In this episode, Michael Jackson of React Training and Rob DeLuca and Taras Mankovski of The Frontside talk about what is a component, and what a component is specifically in the context of React.
They also discuss when it stops being a component and becomes something larger, how it has changed the way we develop UI, and thoughts on container and presentational components being synonyms for controller and view.

ROBERT: Hello, everyone. Welcome to Episode 103 of The Frontside Podcast. I'm Robert DeLuca, a developer here at the Frontside and I'll be today's episode host. We're going to be discussing what is a React component or what is a component with Michael Jackson. I'm pretty excited about this topic, a sort of off from a tweet that I sent out after a long workday, when it is something being called "component" because it was built with React components but it was more like a mini application? Then Michael replied to my tweet, as they're happening and he said, "What is your definition of a component?" which is exactly what we're going to be discussing today. I thought that was a really great question.
With me, as a co-host is Taras Mankovski.
TARAS: Hello, hello. I'm also a developer at Frontside.
Hi, Michael. How are you doing?
MICHAEL: Hi Robert, I'm doing well. Thank you for inviting me to be on the podcast.
ROBERT: Oh, no. Thank you for joining. I feel like this going to be really fun conversation. We went back and forth on Twitter a little bit and I was like, "You know what? This serves really well like a free flowing conversation."
MICHAEL: Yeah, it's something I really like to talk about, specifically, when we're talking about components or when we're talking about React components. I think there's a lot stuff there to discuss and I think that React, specifically has really, at least defined that word for me. When you were talking about your mini application, I was like, "Oh, yeah. That's cool," and to me, that's kind of what these components have the potential to be, what these React components have the potential to be. It's kind of like almost these miniature applications that you stitched together to make a bigger one.
ROBERT: Yeah, that's really cool. I was frustrated at the end of that day, just because that had so much logic crammed into it and you can kind of see that come through in the tweet but I'm not going to lie. After I sent that tweet, I was a little disappointed with myself because it came off a little bit like flangy but I guess we could just kind of jump right into defining what is a component.
MICHAEL: When I saw your tweet, I was like, "Oh, you know like --" and of course, I don't know the component that you're looking at. It could have been terrible. Totally, it could have been terrible. I'm totally willing to believe that it was not a good component. But writing React is hard, especially writing good React is actually hard. At first, I thought it was easy but I think it's easy to solve your immediate problems but to write React to that is generic enough to solve lots of different problems, I think it's actually very, very hard and it's something that I've spent the last couple years learning. Anyway, that's kind of a tangent.
But regardless of the component that you were looking at, the way that I've tend to think about these components is we used to have a model for thinking about how to build frontend applications --
ROBERT: Like MVC?
MICHAEL: MVC, that's the one. That's the one that talking about. You have, here's your model, here's your view, here's your controller. You know, there are separate logical entities and lots of times, those even live in separate files on the file system and we keep them sort of separate and spaced out. As far as I can tell, that's a sort of paradigm. I learned it in school. By the time universities catch up with industry is at least, like twenty years, so it's probably something that was invented back in the 60s or 70s.
ROBERT: I think it was like the 80s because Charles talks about it a lot and sort of Taras, actually because we're building something that's like a composable model, just like the Vue of React is a composable view, its components. I think it's interesting because I was listening to the Changelog Podcast and it sounds like you worked with Ember for a while.
MICHAEL: I did, yeah.
ROBERT: I forget, which podcast that was but we can find it and we'll link it to the show notes but I thought that was really interesting that you also came... Oh, maybe not came from Ember. You had experience with for, at least a couple years and that's where I came from. That's kind of where that tweet came from and was like, "Man, I don't like what happened to the word component," because when I think of component, it's like something that is encapsulated in a small piece of UI. But I'm okay with letting go of that.
MICHAEL: Well, yes. Ember came out of something called SproutCore, which actually originated at Apple. Tom Dale used to be a developer at Apple. I'm sure you all know all of this but just for some sort of back story for others who might not. Apple was a place where MVC was really, really big. The whole Cocoa frameworks. They're all very much like, here's your controller, here's your view, core data has all of your models, that kind of thing.
It's a software development philosophy that goes back a long time and has deep roots and I'm not here to suggest that because it's old it's bad, because lots of old things are actually very, very nice and good, especially in programming. We're starting to see a resurgence of functional programming ideas, for example, which have been around forever, since at least, the 60s or even earlier than that. It's not necessarily that I think that because it's old, that it's bad. I don't.
ROBERT: Right, right.
MICHAEL: But the thing that I do see in these React components is they kind of go very much against the grain. If you had, for example your model, your view and your controller as these vertical silos, just imagine turning that whole thing on its side and then cutting a slices of that, so that each of your React components has elements of MVC in it. They're all sort of mixed together.
I run a training company called React Training and whenever I'm doing one of my training workshops, the way that I talk about it is a component is able to encapsulate three things: markup, which is the view essentially; state, which is essentially your data or your model; and behavior, which is essentially the controller, so what happens when the user is interacting with the view and clicking on the buttons? What do we do in response to the user input? You’ve got all three of those MVC elements in the React component.
In fact, I've been meaning to kind of coin the term for a while. Instead of MVC, I call it MSB -- markup, state and behavior.
ROBERT: You heard it here first.
MICHAEL: That's right, here on The Frontside Podcast, we're coining new terms.
ROBERT: That's pretty great. I guess coining off of that, is it fair to say that MVC kind of still lives on, except it's now in React? Or it's kind of more sliced up into smaller, more digestible pieces? We can always come back to this composability element, right? Would you say like really React would made it possible to compose many little MVC apps?
MICHAEL: Yeah, exactly. The thing that people really, really love about MVC, I think you still have it in React. MVC, the thing that people always come back to is the separation of concerns. Let's just say, "I don't want everything sort of mingled together. I want it to be very clear. What is my model? What is my controller? And what is my view?"
The cool thing about a React component is if you look at it, you still have very clear separation within the single component. You have a very clear separation of all three of those concerns: your state lives in an object called 'this.state,' then your view is whatever you return from your render method. That's in a completely separate spot, since still in the same component and then your behavior or your controller usually has its own method, so you can inline those in your render method or you can pull them out if this is how you'd like to do it. You can pull them out into instance methods. You can still have kind of that separation of the concerns within a single component.
I think to your point, the React component model is all about composition, so this is kind of a term that we've actually adopted in other areas in technology. It's sort of just coming to frontend. The idea is you've probably heard of a service-oriented architecture for design in backend systems. These servers over here are application servers, these are database servers, here's our caching tier, here's our Ingress or LoadBalancer and maybe, you stitch them all together on the backend into one coherent system. You know, here's our storage and our image-resizing services. You stitch them all together on the backend into one coherent system but it benefits you to not build them all as one part of sort of monolith.
We've got a lot of benefits from the decoupling. For one, if one piece of the system fails, the whole thing doesn't go down, so you can like swap it out or upgrade it and replace it with something else. I feel like that is kind of a similar idea to what is going on the frontend with these React components.
ROBERT: Oh, microservice components.
MICHAEL: Yeah, exactly. Each component is kind of like you said. It could be like a miniature application and it could be totally self-sufficient and I could drop it onto a page and it could just do its own thing or what I could do is I could take that app, that component and I could drop it into a larger app that can speak to it and can communicate state to it via the props that it sees and then can get state back out of it via these callbacks. I kind of view it as like all of these miniature systems that they can either be completely encapsulated and self-governing on their own or you can take them and compose them with a larger app.
ROBERT: That's really interesting. I guess what is a component specifically in the context of a React. I guess, we kind of just answered that, that you can bundle all these things together, right? Does that make sense?
MICHAEL: Yeah. The beautiful thing about this composition model is you can have all three of those things in the same component: markup, state and behavior. You can have all three of them right there, encapsulated in one component or once you discover more advanced patterns with React, you can actually make it so that a component only has two of the three or one of the three.
ROBERT: And then it kind of like passes callbacks or props or state around?
MICHAEL: Exactly. It can essentially delegate the responsibilities for handling the other pieces that it misses to other components around it. There's a pattern that I kind of coined last year called render props.
ROBERT: Oh, yes. I remember hearing this on Changelog Podcast. I was actually one of the people that at first thought it literally was a prop name render.
MICHAEL: Well, I mean it's not a bad way to think about it. It could be a prop name render.
ROBERT: But then I found out it actually is a prop that you send JSX too and render whatever is there.
MICHAEL: Yeah, exactly, a prop that you used to render stuff. It's the way that I describe it. When you think about it, any component, for example that accepts a render prop is really just delegating it's rendering to some other function. It can contain the two pieces: the state and the behavior, but then it can sort of delegate this third piece, which is the markup and say, "You know what? I don't really care about, specifically what I have to render." I don't have an opinion about that. You just give me a function and I'll give you my state and possibly, some behavior callbacks and then you can tell me what to render. I'm like a component that I have two of those three pieces. I don't have the markup, you just give me a function, that I will call when I need the markup.
ROBERT: That's really powerful.
MICHAEL: Yeah, exactly. I can have all three in one place or I can also with this component model, just delegate one piece or even two pieces, using these kinds of patterns to other components, so it's really nice.
ROBERT: I'm always have to come back to this because this is where I kind of cut my teeth in the frontend world. I feel like render props are very similar to the yield pattern in Ember, where you can yield out a component and place it anywhere inside that template block. I think it's really similar. Because we have a large base of Ember developers that listen and they needed a draw like a parallel, I would say that's almost a parallel. I might be off on that. Taras, would you agree with that?
TARAS: Yeah, it's very similar. There is one little 'gotcha' with render props in React, which I think Ember deals with a little bit more gracefully. I do use React all the time now. I use it much more often than I use Ember but --
TARAS: Yeah and I'm kind of curious, Michael if you would think about this. Because there are certain things that, for example, JSX does, like one of the attributes of using render prop is that you want to pass stable functions, like something that is actually defined in init hook, so you're not necessarily recreating a new identity for this function every time that you pass into the render prop. Is that right?
I think for someone who is might not be familiar with this, it's a little bit counterintuitive because it just kind of like, you just pass something and then you later realize, "Actually, I can't really do that because now your components were rendering over and over again." I'm curious like where can we kind of innovate in that? Because in Ember world, for example, it's really safe to use render props. If you're delegating to the context to do the rendering, you can very easily pass a block of template into the component and then the component will know how to render that in a performant way.
My experience with render props in React was that the pattern in Ember is it's a very common behavior to delegate to the context of how the children of a component are rendered. This is the primary purpose of the yield in Ember and this is used by a lot of the components to provide APIs, so essentially, you're yielding, you're sending into the children function behavior that you want the developer to use while consuming your component.
The parallel with React is that you would have, essentially a function, like you have a children render prop, which is a function that receives so that when a component is rendering the children render prop, it's passing some data into that function and it's invoking the children function and it's passing to it some data and then that data is being used inside of the children render function.
Now, this mechanism works really well in Ember because Ember is using its own templating engine, so it manages every placeholder in the entire template as being passed into the component. It knows exactly what has changed in the function. Looking at that, the value just passing through component as a whole thing. It's actually managing each individual spot where the dynamic elements needs to be rendered. What that does is it allows it to manage the entire children function so you don't need to worry about stabilizing the render props. You don't need to assign them.
Because there's also other challenges that kind of arise when you have to move the actual function that you pass into children. You have to move into the body of the actual component. Your ability to compose the state that is within the render function is kind of limit because you now have kind of broken up into different places. I'm a little bit curious what are your thoughts about this? And if there's any innovation that's going to require or improvements that will require in the way that React handles render props.
ROBERT: I definitely remember seeing some tweets from you, Michael about this, like very recently.
In a lot of ways, it's more flexible but with that flexibility comes this extra concern of what happens with the prop passing and it's a real concern but I don't think it's as big of a problem as most people have heard or might think it is. The real problem, the root of the problem is that if you have a pure component in React, the pure component is optimization tool in React, if you find that your component really is a pure component of just a pure function of its props and state, and that it will never render anything different, if it receives the exact same props and state, you can declare that that component is a pure component. Instead of just a regular component, it's now a pure component and so, it will actually opt out of the render cycle if it receives the exact same props and state on subsequent render. By exact same, what I mean is like identity triple --
MICHAEL: -- Same. That's an optimization tool that you can use in React to say for example, maybe I've got a component and for some reason, it's always receiving the exact same props and it's rendering a lot. I can say, "You know what, React? Don’t even waste your time re-rendering this component and doing the reconciliation around it and everything like that. If it receives the exact same props, don't even waste your time. This is a pure component. It received the same props. It's going to render the exact same stuff as it rendered last time, so it will completely opt out of the render cycle," so React won't even call the render method, won't even bother doing the reconciliation for that component or its descendants. It's actually a really, really nice way to get a little performance boost in that situation.
ROBERT: Interesting. Does that mean, rather than passing some JSX that returns out an anonymous function, you would rather have like a pure component over that?
MICHAEL: All it really means is that when you identify a place in your app where this is happening, instead of extending React component, you can extend React.PureComponent and now you component opts out of the render cycle.
ROBERT: Gotcha. Because I see a lot in React applications, it will just return some JSX out of anonymous function, kind of think, Taras was getting at, when each re-render happens, it's recreating a new function and all of it were done inside of it, from the JSX because it's just a new function that's being bound each time.
I think my takeaway from that and correct me if I'm wrong, is don't pass JSX and an anonymous function or I guess, from your tweets yesterday, that's kind of a premature optimization. Maybe, not pass as anonymous function but pass as pure component.
MICHAEL: I hadn't yet gotten to directly addressing Taras's concern but the idea is --
ROBERT: -- Jumping the gun.
MICHAEL: Yeah, it's fine. If you do have a pure component, that is when you're going to have a problem with this render prop pattern because you can't pass a render prop to a pure component. They just don't go together. Well, sorry. I should actually qualify that. You can pass around a prop to pure component but you need to make sure that it is always the exact same function, otherwise why are you making this thing a pure component, so there's a little bit of a problem there.
I actually wrote the documentation on React's website on render props and there's a little caveat section where I discuss how you could get around this, you could convert it into an instance method or something else but then the concern at this point and this is why I said it's not such a huge problem because we're getting very, very specific now. Let's assume that we've got a pure component that is the child that we want to render and it accepts a render prop and that render prop depends on state and/or some sort of scope that it needs in the render method.
Now, we've got a problem because we need to generate a new function in the render method and the fact that we're generating a new function and passing it to a pure component means that we are essentially negating all the benefits of extending pure component in the first place. First of all, in order to experience the problem, you have to get very, very specific and it's not easy to actually get into a point where the problem manifests itself.
But then for the second part, fixing the problem is actually not tricky, so the way that you would fix this issue, there's a couple of ways to fix it. The most common way, I think to fix it would be to just say that pure component, let's just move that down one level and we'll put it inside the render method of the component that takes the render prop. The component that takes the render prop is no longer pure but the pure component has dropped down one level and we can still get all of the benefits of a pure component and again, its whole descendant tree lives underneath it.
ROBERT: That make sense.
MICHAEL: So, we can still get all the benefits of having a pure component, while still being able to use the pattern. But again, just getting back to what we were saying at the beginning. The render props is just one example of an advanced pattern that actually lets you delegate one of these three pieces to somewhere else. It's just one pattern. It's not like there are others as well.
ROBERT: Yeah, so getting back to what is a component, is there ever a line that's drawn, like when does it stop becoming a component and it becomes something larger.
MICHAEL: It's actually interesting because for a long time, we didn't have a component model on the web and I think --
ROBERT: It's very true.
MICHAEL: -- still, like we mix to all three things together in our jQuery code. It was just like there was some state mixed in with some markup, mixed in with some behavior. It was all kind of mixed into one place.
ROBERT: Nice plate of spaghetti.
MICHAEL: Yeah, exactly. As soon React came along and actually gave us a real component model that really worked where we could actually identify these pieces, then all of a sudden, everything is a component and you really can make if you want, like if you really wanted to, you could make your entire application out of components. It could just even behavior stuff like, "I want to fetch some data," that could be a component or, "I want to listen to the window scroll or the window size," that could be another component. "I want to render an image or a bit of text or do some measuring or I want to do some parsing of some data or something like that," all of this stuff could be represented as components if you wanted it to.
Of course, you can still extract those functions out into their own bag of utility methods and lots of times when I write a React Apple, I have a little bag of utils and I'll go and reach in there and grab those as I need them. But for the most part, most of my React apps are just components all the way down, so there's not much that I can't do with a component. The cool thing about that is what do you get when you have components, where you get reusability and sharability. I can make a component and I can just share it with you, Robert. I could say, "You want a component for listening to the windows size? Here you go. Here's the components. Got to render --"
ROBERT: Drop it in.
MICHAEL: "-- It will give you the size when you need it," so that ability to share code is, I think super important.
ROBERT: Yeah, I think so too and it really helps you build applications rapidly because you can just start dropping these little components that are contained in composable throughout your entire app.
I guess, I'm still clinging onto like there is maybe a line that is drawn and I think from the React community, there were a couple of terms coined called the container component and the presentational component, in which I immensely mapped those to basically being synonyms for controller and view. It's like the container components is kind of like a controller, like it delegates the view... Or decorates the view, not delegates. And the presentational component is just like we're talking earlier -- pure component. It's just taking props and rendering that. Is that fair to say?
MICHAEL: Yeah. As far as I can tell, that's a pattern that was first talked about by the redux community, specifically I think Dan is the first to discuss that that pattern and it's a pattern that I think can work well. I haven't ever found it to be especially useful in my code but I can see how other people could like it for their code. I really just think it has to do with how your brain works. If you prefer structuring things like that, if you prefer like the vast majority of your components to just be these little view layers and then your main container components to hold all of the logic, I want fault you for that. I'd say, that's fine you can build your app like that.
But I do think that when you're thinking about components like that, you are thinking about the much less like these miniature applications. Basically, in my opinion it's kind of a false separation. It's a separation that doesn't really need to exist because essentially, the thing that I really love about these components is you have encapsulation. You encapsulate everything. As soon as you adopt this pattern of containers and essentially, just these presentational leaf nodes, they're not as useful on their own. They just encapsulate some of the rendering logic.
ROBERT: That's very true and they're not reusable. I mean, it's very, very hard to make those reusable.
MICHAEL: Well, yeah. Most of the time, they're designed to be used with a very specific container. It is like, "Why couldn't we just put that in a container." Like I said, I really don't fault anybody for using them. It's just not how my brain works. I tend to think more about components as if they were these miniature applications and they're going to be useful on their own for the most part.
One place where I have started to do that, the fourth thing that your components can encapsulate is style information, which is really just kind of the markup but it's the fourth thing and I think that I've really started to employ that kind of pattern when styling comes in. But it's not for this separation of containers and leaf nodes. It's just because I would like to encapsulate some of the styles down at a lower level or be able to reuse some of the styles down at a lower level, so that's when I'll typically start breaking up one of my components into multiple kind of tightly-coupled components but it's just for the sake of the styling, not really in any of the control flow or the logic.
Sure, there's edge cases that's like a blanket statement but I think those lines of separation is way more blurred these days and I think that's what React just unlocked. That's kind of where all of this is sort of rolling downhill and it's not a train. It's really powerful to be able to encapsulate all of those things together and then just think of your UI as these components. That's why we call them components. They componentized.
Like when I have a butt-in and I drop it on the page, I don't want to have to go and make sure that I have the right class that's wired up in some other file. I can just drop the button in there and it's going to do its thing. I can pass the props, it'll change it, that's fine. It lives within itself.
MICHAEL: Yeah, I would say you're absolutely right. You can't ship anything meaningful without having, at least some styling in there, unless you're shipping very, very basic behavioral style components. It's kind of one piece, I think like the React components are able to encapsulate their own styles but there's no, I guess officially recommended way to do it, which is where I think React get some of the critique, like some people come in and say like, "There are a million different ways to do styling in React and therefore, React is supposed to something like --" I guess, yeah, some of the other frontend frameworks have like, "This is how you do styling in our framework."
ROBERT: Right, like the lack of convention.
MICHAEL: Yeah, exactly. It's a blessing and a curse, though. If there's a lack of convention, it's harder for newcomers to know exactly what to do.
ROBERT: Yeah, or like what's best for their use case.
MICHAEL: Yeah, exactly but then on the other side, it's kind of a blessing because people are free to experiment and they don't have to feel like if they're experimenting, they're going sort of against the grain of what the community has already accepted to be the answer. I think that freedom to get out there and experiment is really valuable as well.
ROBERT: You can see but I'm nodding.
TARAS: I'm just curious what your thoughts were. This Suspense API is something that's... React kind of lead the way with components and now, the changes that are coming in with Suspense API coming in and it'd be great, if you can, are you able to explain a little bit about what it does for people that are not familiar and I'm curious what your thoughts about it.
MICHAEL: Yeah, for sure. The Suspense API, I think is actually, with regards to what we've been talking about, with the encapsulation of markup, state and behavior and possibly styles, I think the Suspense API is kind of the React teams attempt to sort of encapsulate or generalize, at least one more thing, which is asynchronous behavior.
The truth is, the most common async behavior that we know of, that most people are familiar with is a fetch, a data fetch -- you go and fetch some data. But there are others, there are things like loading of images and animations and navigation and things like that, where you have some time that passes in between when you initiate an operation and when you're actually able to render as a result of completing that operation.
How do we manage or how do we generalize that and how do we think about it? The Suspense API is basically a way to declaratively say, "I need this async operation to be done." Let's just use the example of a fetch. I need this fetch. I need to have fetched this data in order to render this view and don't even attempt to render this view, unless the data has been fetched. Before the async API or Suspense, as they're calling it, you would basically have to manage this asynchronous behavior yourself. You would basically have to say, "Go and do the fetch," and while we're doing the fetch, maybe I'll set a loading flag in my state and say, "Loading is true," and then when the fetch gets back, I'll say, "Loading is false," and then I'll render. Maybe, while loading is true, I'll show like a spinner or some loading dots or something.
What the Suspense API allows us to do or what they're hoping to do, again it's all very like... I don't know if I made this clear. It's still very, very, very, very early days for this API and I don't actually know when it'll be ready. But anyway, the idea is to be able to say --
ROBERT: Would you say the Suspense is killing the community?
MICHAEL: The suspense around suspense.
ROBERT: A terrible pun.
MICHAEL: Anyway, the API is basically just a more declarative way to indicate where this asynchronous stuff is happening and give React sort of clues, if you will, to say, "There's some asynchronous stuff happening here, just so you know." That has many applications in the real world.
Let's say for example, you were navigating in a master detail view and you're tapping down the master view and loading these detail views, if you tap a master view and you haven't yet loaded the information for the detail view, instead of sliding to the detail and showing the data still loading there in the detail view, you might want to show some sort of loading indicator while you're still in the master view. Then, if it's taking a while to load, they can actually select something else from the master view and in that case, you would cancel the old fetch and start another fetch. It's just supposed to make things like that, kind of feel a little bit more fluid and a little bit more intuitive to the programmer, so you don't have to think so hard about managing a lot of that complexity in your own head.
ROBERT: Yeah. By the way, I love the mobile first language that you used. You tapped here, you tapped here, that slides in.
MICHAEL: Yeah, for sure. It's all we're building these days.
ROBERT: Yeah, it's very true.
TARAS: It's interesting because the Suspense API, you wouldn't really imagine it to be within the scope of a view in a traditional sense, to [inaudible] but considering the scope of a component in React, it makes sense but I think people might not imagine as being something that would become part of core, potentially in React. I'm curious like what do you think other areas of React and I'm glad that the scope of components in React is so broad because it kind of opens up this question to be pretty much anything in React ecosystem. But is there an area of React building or the aspects of applications that you would like to see an improvement in or some kind of a change or something that hasn't seen the right amount of innovation in the same way that we've seen in other areas?
MICHAEL: Basically, is there a place where I would like to see the React ecosystem improve?
MICHAEL: I know this goes kind of contrary to what I just said but I would like to see a little bit more cohesiveness. I feel like in some ways, the freedom is good but I also feel like in some ways, for the last couple of years, we've been just sort of like rehashing the exact same old problems again and again because React really made everything else so easy, like a lot of the stuff that was hard about building web apps, just got really easy when React came along.
I'm not saying that because I have React training company. Of course, my livelihood right now depends on React but honestly, if it wasn't for React, I think I probably would have quit and done something else because it was actually getting really, really difficult for me. I was trying to build an app in Ember before I started with React and I just couldn't do it, you know? I just couldn't get the level of polish that I wanted in my app and get all the bugs out and get it working exactly how I want it to. It frustrated me, actually that I've spent a lot of time.
I spent about 18 months, about $100,000 of my own money, just down the drain trying to build this app, trying to get it out the door and I wasn't able to finish it off. At the end of the day, I really started to question like, "Was it me? Do I just suck? Am I not a great developer? Is that the problem?" You really have to start asking ourselves hard questions like that when you put everything you have into something and it doesn't work out and then React came along and I was like, "I was just using the wrong tools." The tools were the problem. It wasn't me. There is a different way to think about this about building stuff.
I thought the way that I was doing it was the only way that existed to build things but it turns out, it's not. I used to not understand what were people talking about when they were talking about functional programming or what do they talk about when they're talking about composition, solving problems with composition, instead of inheritance. I didn't even understand what that meant. But all I knew is really smart people would say stuff like that and I was like, "What are you talking about?" Now I feel like, because of React, I've gotten it.
Again, to get back to your question, Taras, React made a lot of the stuff that we used to worry about, that we used to think about. It made it easy and so, we could build amazing things now a lot more easily. But now, for the last couple of years, I feel like we've just been sort of rehashing a lot of the same stuff.
I would really like to see us, as a community sort of tackle the next level problems. I think the React Suspense stuff is definitely getting there. That's a problem that I really don't see anybody else sort of address, which is how do I make it easy to deal with the fact that applications by their nature -- these networked applications -- are asynchronous. How do I deal with that in a declarative way? That's why I'm encouraged by that work because I do think that it's kind of one of the more forward thinking things right now that's going on in the React community but I would like to see us in general, sort of like get past talking about styling and get past talking about service and rendering and move on.
ROBERT: Right and I'm going to assume you have this really unique experience since you do a lot of trainings. I follow you on Twitter and it's just always talking about where you're flying to and who you're training, so the things have to come up there where you see these things in pattern over pattern over pattern.
MICHAEL: Yeah, exactly. I see like a lot of and this again, gets back to Taras's question. I train a lot of people who are very new to React and I see people who are new to React, they really don't have a ton to go on besides just like blog posts and Medium pieces and podcast like this one and who am I? A lot of people in their React community don't even know or care who I am. It's like, "There's a guy out here who are saying stuff about React. Maybe I should listen to him. Maybe I should listen to somebody else," and it's confusing. It's confusing, I feel like, for people who are just getting into React. It's confusing. Like I said, experimentation is good but I guess, I wish the experience of coming to React was a little bit more like the experience of coming to Vue because --
ROBERT: Oh, like it was a beaten path.
MICHAEL: Exactly. I don't actually think there's not a whole lot about the Vue technology that is compelling to me and let's not dig on it. It's just --
ROBERT: A personal preference?
MICHAEL: Yeah, exactly, just preference but I do think the thing that is very compelling about the Vue experience is just the cohesiveness of it all. You go to Vue and there's like a way to do server-side rendering with data fetching and styling and --
ROBERT: They have a CLI and --
MICHAEL: And a CLI and a component and all these stuff. Yeah, and a router built right in. Anyway, I think that's a way that the React community could improve. I don't know if that'll ever happen because the React community at heart is artists and hackers and those people are traditionally very reluctant to be corralled and like I said, it's a blessing but I think from the perspective of people who are new to the community, it does tend to cause some confusion.
TARAS: I want to add to what Michael is saying. What's interesting and I'm sure Michael sees this in his training but the kind of people that use React is very diverse. There's this kind of original group or there's kind of mentality that prompted the early adopters of React and now, we're seeing these companies that are traditionally enterprise-y with MSE backgrounds and coming into React. It's really interesting to see all this kind of worlds collide and then see what's happening as a result. It's definitely interesting on what's going on now.
ROBERT: This is an excellent stopping point. I really agree. I come from Ember background so I would like to see a little bit more convention but I think it's okay. It would be nice to see that.
Thank you, Michael for coming on. Is there anything that you would like to give a quick plug for and where people can reach you?
MICHAEL: If you want to support the work we're doing, you can sign up for one of our upcoming workshops. We've got one right now on ReactTraining.com. We've got a workshop coming up, actually in my hometown of Carlsbad. You can come out here in July and hang out with us and do some React training. We got a really awesome host here who's right here in town. We're doing some React training workshops on July 25th through 27th, I think and then, other ways that you can support what we're doing is publish in all my open source code at GitHub.com/ReactTraining or you can follow us on Twitter at Twitter.com/ReactTraining or at my personal account at @MJackson -- Michael Jackson.
ROBERT: Awesome. I really appreciate you taking the time to come on.
MICHAEL: Yeah, thank you so much. It's been a pleasure.
ROBERT: This is a great talk. Cool.
