No worries! Very well done video. Very informative. There's a lot of beginner content on UA-cam but not as much architectural content, so I really appreciate you sharing your take on the subject. Just subscribed! Looking forward to more of this kind of content 😁
I've been using the compound component pattern for a while and this is a great visual explanation of the benefits and how it's implemented. The pattern is a good example for Separation of Concerns / SOLID principles - Single responsibility, Open-Close, Dependency inversion.
i really dislike this sort of composition. i call it fake composition. the internal components are just a longer way of specifying props (as opposed rendering something). - components become 10X more complex because of the need to maintain a context and everything around it. - zero type safety. which components are allowed inside? is the order important? how about nesting? - because of the type safety thing, you need to maintain docs for the thing. instead of just asking TS to let you know which props it accepts.
This comment is underrated. You also turned each of these components required to be used within a context. Instead of using props, makes the sole use of the component to be within the product card component. It its also very hard to test, as you need to mock a context in order to be able to test the components instead of simple passing props to the components youre testing. Props > context api. This is simply over engineered
@@ChristianMoentest Valid point, and I do not advice using this pattern everywhere. It's very helpful for building design systems, especially public libraries as this prevents unintended usage and simplifies the API for the user. The testing is indeed a bit harder, though I don't see much point in testing the sub-components individually as small and simple as they usually are.
@@codevincas So for me, a real composition would be something like Settings. If the internal components are just a fancy way to set props it's just an over complicated configuration method IMO.
1. How do they become more complex? You create a context and wrap a Root component around the Provider. You can create all your components in a single file-is it really that hard to maintain a scoped context? 2. Why does it matter which components are allowed? Order shouldn't be important. You're creating arbitrary restrictions that makes it harder to reuse for other cases. You're making up an API which takes _more_ effort to implement than just accepting any component. If your intent is to map over the children to stuff props onto them or filter out, then don't. That's what compound components solve for you. Compound components makes decisions easier at the consumer level, rather than implementation level, making them great for reusability. 3. I don't get this. The compound component is just a component built up of other components, whether it provides a context or not. Each component defines their own props. That said, this is by no means a recommendation that you should make everything a compound component. It's still more effort than just making a special-case component that does what it needs. However, they are a great abstraction when you want more flexibility without imposing restrictions and unnecessary implementation details.
What a great way to group components and their relevant data. I've been using React in production for nearly a year now and it never occurred to me to use a Context at this deep level before. Really good video, thanks for sharing!
Same here, using Context at deep level sounds like a nice idea. But as many others have pointed out, it comes with its own challenges of tightly coupled component that could have been mistaken for "NOT TO BE REUSED AT OTHER PLACES".
Hey Vincas, I just wanted to let you know that this was a masterful lecture, and really informed my coding style! I'll be writing a small storybook component library for my startup this week and your patterns have really shaped the approach I wanna take. So thank you for providing such high-quality instruction! Secondly, I just wanna point out for anyone that uses NextJS *13* that context is a client side feature, and will not work without the "use client" directive at the top of the file. This also means that if you want to fetch data server side, say in an async function, you will probably need to have a state initializer component that can interface between the server and client. Jack Herrington (author of No BS TS -- and he has a UA-cam channel under his name) has a video going over state management in NextJS 13 to cover this topic. Again, Vincas, I really appreciate this! Thanks, and greetings from the US 👋🏽 Subbed.
Nice video! I like the demonstration of Component Composition and also the "name-spacing", however, I wouldn't agree with the use of Context API here: Firstly, in the first part of the video you show how to make the component more reusable with Component Composition, but then with the Context API you introduce maximum-tight coupling to the Context, which arguably impedes the reusability. Secondly, in a way, I'm thinking Context API is just "hidden" prop drilling where the dependency isn't visible at first sight, which might not be ideal in terms of readability for other developers.
Correct, also gosh !! if anyone is using vanilla js with react good luck accessing/handling those product attributes after change in product's attributes.
Agreed, I'm definitely going to apply the idea about Component Composition, but the rest of the video sounds like it's better for demo projects to look as "clean" as possible rather than for real-world code. I'm more likely to use , and and other similar lower-level components as children rather than , and . It's a lot more flexible and it's still very readable.
Really clean video, showed the process really well. I think the really great thing about this approach is that you can easily create variants. It is really good if you need to use the same code base to support multiple clients for example.
danggg it! I've seen this pattern started from headless-ui a couple years ago and nowadays as my experience increases, I see a lot more, the most recent is radix-ui which I (we) love hahaha I try to learn this kind of approach back then from headless-ui, sadly I understand nothing, lol. A couple years later, I try to learn again from headless-ui and radix-ui, then your video showed up at the very right time. thank you for making a very clear tutorial and a good example whereas this kind of card can be very complex at some point. I really enjoy watchin this video a couple of times. Thanks! 🙌
Very good content! As some people already pointed below, you need to work on the editing. I know it is hard, but this type of things helps to understand better your content.
I see this composition pattern in the MUI implementation, personally I think this may suite for base components with infrequently change structure. Suppose your Card component need modifying to grid style, it's hard to maintain both `slot` styles and props-components styles. Another problem is manage reference of slot props, which can lead to performance issues, but if you using old class component with some properties like `renderImage`, `renderRating`, etc, this is a good way to simplify your component.
@@davien001 Yes it would, but at the same time you will have to maintain multiple memos instead of having a single memoization step for the entire component.
This is a good pattern to use, especially for low level components. prefer slots over props to keep the code of the component easy. Another suggestion i would give is to make the components do as little as possible, whatever you are not sure is not going to be reused most of the times should stay in the parent, i think a common mistake is to pass the options props to a Select component, but the options may be in many format, value-label, value-label-andLotOfOtherStuff, maybe you don't even need the label because you are showing a bunch of icons, also the options may come from an API or may be filterable, and the filtering logic may vary, etc. So just move the handling of the options and the selection of the value in the parent and it will simplify the code of the Select greatly, while the code in the parent would be easy to understand because it will be very specific for that Select.
10 seconds in and I’d already subscribed! Really liked this tutorial, looking forward to your future content. UA-cam needs a lot more React design pattern videos like this.
Sam Selikoff has a great set of videos on implementing RadixUI components which follow a similar design. In fact, once I saw the end result of using the Context API to make the components modular I couldn’t help but think I had seen it somewhere before. It was a great video and I learned a lot! Subbed 😊
I myself, prefer to develop components so they're easier to use consumer side, I feel like providing variations of a component as a prop is much easier, pass through an Id for the product, and have all logic relating to fetching and deciding layout to the component, learning curve for other developers is much nicer, and you're using the same composition in every place, it makes it much harder to fix bugs or make changes, where if it's inside the component, maintenance is much easier, you end up having to create wrapper components too many times with composition too so that things are reusable
This was very helpful and informative! I have a couple of questions if you have time to answer: 1. Why does use slot props as opposed to only "children" like the compound components? 2. Are there concerns about bundle size when using compound components since you're always importing all of them?
old comment but I'm guessing slots restricts the order of components or DOM structure (ie image on top, info in the middle, cta button on the bottom) based on ProductCard's implementation while children have more wiggle room
Thank you for the video. You can achieve namespacing by perhaps importing everything on a separate file as non default exports if the issue at hand is too many lines of imports. I will personally always favour to as on the latter you're creating a data dependency where the first one you can easily erase Product and will still exist. You could then import everything in one line.
Great video! I can't to help but to ask why do you think this is a good approach? When in fact we can make the component accept one prop, and object with all the data necessary to render the component.
You could, and for most components that's totally acceptable, and anything more would be overengineering. As I mentioned in the beginning of the video - what happens when you want to slightly change the appearance of the component, for instance hide some parts of it or add a small bit of logic? You'd add boolean flags and change the component implementation logic to accommodate for them. That's fine while there aren't that many flags - most components never reach that point, so that's ok. But particularly design system components are often used in multiple different ways with slight tweaks for each use case. In that case changing the implementation of the component becomes risky and cumbersome, also the component's implementation logic would grow to support all those different use cases and the prop list would be mostly a bunch of boolean flags. Just passing in an object doesn't help in that case, because it doesn't change the need for those flags and in many cases design system components won't even be using a domain model (the object), but rather generic props to retain flexibility. In that case, composable components are superior. If you want to use the context and compound components - that's your decision, in many cases it would be over-engineering, but in some, they're a nice way to group components together.
Let's see if I understood correctly the right use cases of this: I should/could use this whenever I have a component that needs some more details, but those details alone wouldn't be something that I could reuse elsewhere Seems like this, am I right? :)
Hi! Excelent video, but I have a question, React recommends to use Component Composition every time it's possible and avoid (as much as you can) the use of ContextAPI (Re rendering problems). Will you use Context in a real app in the way you are showing right now? Thanks.
I would like to follow over your video from the initial code. I'd like to follow along while watching the video, starting from the initial code. Could you possibly provide the initial code too?
I didn't quite understand what are the benefit of passing the image, info and action components vs adding them inside the ProductCard once you've already implemented the context. Wouldn't it be simpler? you'll just have to pass the product as prop and the components inside the ProductCard would get that through the context.
The "slots" is a way to delegate the layout/design decisions to the user of the ProductCard. Without them you'd have no way to make certain parts invisible, reorder them or extend the component easily (without changing the implementation). Basically, this improves flexibility by making the component composable, and the context is just a bit of sugar on top, to reduce the amount of props that need to be passed around.
@@codevincas The props does not delegate those decisions to the user but to the ProductCard itself-you exactly need to change the implementation of ProductCard because it takes those props. What Prizel is saying is that you could make ProductCard component itself take those compounds as children, since it already provides the context for those components to consume, then pass the product as a prop to the ProductCard. You'd now have even more flexibility over the layout. Even better, you could use the Radix UI Slot component to further allow other types of user-defined components that will merge its props into the immediate child component. This is a, arguably, better way of handling custom components instead of dealing with `as`/`component` props that otherwise are hard to create types for.
Hey,, excellent video! Just a quick question. Let's imagine that you have to render 100 ProductCards. In that case, would you create 100 Context for each card? Thanks!
Nice video! Quick suggestions: 1. Add ambient music in the background to make it more immersive while watching 2. Make the video more about the topic and example code by having snippets ready to paste than typing manually 3. Could work on some tone modulations while explaining i.e varying intensity, some animations, etc. Watch Hyperplexed on YT as he grew very quickly due to loopable content. Good luck!
Thanks for the comment, I might add BGM in the next video and I do need to work on the smoothness of my talking, but it will come with practice I hope. I'm experimenting with different ways to present code atm, will try to do some copy-pasting in some sections for longer videos, or edit out the typing part. Hyperplexed is next level stuff, he's not doing long-form tutorials, but is definitely inspiring though.
1. I'm actually quite happy there's not background music. If I wanted any, I'd play my own 😅 2. As the typing has roughly the same duration as the explanations... I think they match well.
would it also make sense to put the subcomponents as default values for the Product props and allow them to be nullable, so you would get a default Product which is used most often and you don't have to compose it every time, but you still retain all of the flexibility when you need to have special cases
There's nothing stopping you from doing that, though I would probably create wrapper components for different use cases instead, and leave the composable components as a lower level API.
This is a great pattern but could easily be broken by other engineers who didn't know what components to pass on the slots, which can be solved by strictly typing, this has pros and cons
Sorry for the gaps from 4:56 to 5:00 and 5:05 to 5:09, editing fail, will try to double check better in the future 🤦♂

3. Could work on some tone modulations while explaining i.e varying intensity, some animations, etc.
Watch Hyperplexed on YT as he grew very quickly due to loopable content. Good luck!
Thanks for the comment, I might add BGM in the next video and I do need to work on the smoothness of my talking, but it will come with practice I hope. I'm experimenting with different ways to present code atm, will try to do some copy-pasting in some sections for longer videos, or edit out the typing part. Hyperplexed is next level stuff, he's not doing long-form tutorials, but is definitely inspiring though.
1. I'm actually quite happy there's not background music. If I wanted any, I'd play my own 😅
2. As the typing has roughly the same duration as the explanations... I think they match well.
No BGM necessary. It's a distraction that will compete with his voice, which is the most important element of a tutorial video.
Hard disagree. I don't want ambient music.
I liked the typing
first time someone wrote react code using a typewriter!
would it also make sense to put the subcomponents as default values for the Product props and allow them to be nullable, so you would get a default Product which is used most often and you don't have to compose it every time, but you still retain all of the flexibility when you need to have special cases
There's nothing stopping you from doing that, though I would probably create wrapper components for different use cases instead, and leave the composable components as a lower level API.
@@codevincas that makes sense, loved this content btw, cant wait to see more from you
Great content!
Very nice
This is a great pattern but could easily be broken by other engineers who didn't know what components to pass on the slots, which can be solved by strictly typing, this has pros and cons
very good video, you opened eyes :D Got a sub
Super nice, thank you for this! By the way, any way to do this with React Server Components without having to use ‘use client’?
nice 🔥
Great video lol it makes me want to refactor my whole codebase
Glad you enjoyed, but don't refactor unless you absolutely need to.
This looks like combining the "Render Prop" pattern with "Compound Components."
