You are a life saver! This is just so timely as I was about to abandon the monorepo (pnpm) setup having failed to setup Storybook. Really love your style of teaching, please don't get tired creating content. Much ❤ from 🇵🇭
All your content is so clear and cool. Thank you for it. Im a 4 yrs exp. developer (I guess I'm just starting my career) and I see you as the person I want to be in the future. Calmed, nice and enjoying sw development. Taking care of yourself and the others. Btw, I think the first unit test is flaky tobethruty() will pass even when the array is empty
I am not a person who comments a lot on youtube, but there are cases in which it is impossible not to, your videos are very valuable, the way you explain is excellent and goes beyond the basics that other youtubers do, I can't wait for more FE stuff such as architecture, patterns... THANKS!
Although I didn't get hired yet, I'm finding myself more and more immerse into front end development. Your videos are absurdly useful and I feel like I can watch any of them without prior knowledge and just learn some cool shit. I even refactored stuff from older projects with some of the ideas you provide. Really innovative solutions too.
You have a very nice way to explain things. It would have helped me a lot to have someone like yourself to teach advanced concepts in such an easy to understand way.
Great video, React, Storybook and Test. Honestly the work you do is amazing, and I say it as a Developer and UA-camr, from the explanations to the animations. Thanks Jack
Pro tip: you're already creating stories with the correct or example props set. Instead of importing the component directly into your tests and addingprops there again, import the story component to avoid dupe code!
Thanks so much! Recently found your channel and been loving your content. I know you mostly focus on React & Web dev (at least from what I’ve seen), but would love to hear your approach to putting together a cross-platform (React / React-Native) UI library. Thanks again for all the content!
Like how you use pnpm I like having all related things in their own folder as well (storybook, tests, styled-components, etc...). Ohh and I love MDX as well, yay Great video, nicely done!
Great intro to storybook! I feel like a lot of devs tend to over-engineer the component libraries especially in smaller teams when they are trying to build something like bootstrap og material design while all they need is just a simple set of primitives. IMHO you don't always need a full blown styleguide.
Storybook is a cool package) But there are some cases when we don’t need all the power of storybook, but just a simple “test page” with all our components where we can play with its props. There is one package that works just fine for this, called storybox-react
This approach would break things in next13 , you need multiple entry points to avoid components with hooks getting imported together ina server component
Brilliant work Jack! Thanks for your videos especially in these difficult times. I really appreciate the time and effort you put into making content. Hope everything is getting better at home. Take care and get well soon to your wife 🙏🙏🙏
Hi Mr. Herrington, can you please explain the concept you spoke about at 21:55? So as I understand, it's not really necessary to perform testing/create a storybook on every component you create - just do it for the "bigger" components that render out the smaller ones, like the header, hero, shopping cart, etc?
Making it pretty is our task peeps 😂😂 Maybe you can do a video on localization with i18next, it's fairly simple to setup but I don't see anyone implementing it. I implemented it from the start and adding new translations is just adding a new key value pair to the json, I love it!
Hi jack I think you can extend this amazing tutorial with a part containing proper guidance for build step as a npm package. I find there’s scarcity of quality materials on this topic. Rollup will be a good choice for you to demo with, unfortunately it’s pretty messed up especially for typescript.
If you are using a monorepo architecture with module federation, would a UI library like this also be exposed via module federation? Or would the UI library components be built/versioned and then imported as npm modules by the main application.
It wouldn't. In this particular setup there are other libraries that are shared via Module Federation so that you get both live updating and fallback on a compile-time version if the lazy loading fails.
How about atomic design? How would you structure the library? Will you separate it in folders (atoms, molecules, organisms) or just keep the file structure the same and separate it visually in the Storybook with "title: 'Organisms/Card" for example? Thank you Jack!
I would have one library of the atoms, and possibly commonly used molecules. Then I would have other libraries for the un-common molecules and organisms. I'd possibly have a dedicated storybook project that would including all the stories from all the libraries.
As of the release of React 17, there's no need to import React in react components anymore, for reference, look for: Introducing the New JSX Transform on the official react blog
Hi sir, thank you so much for the video, but I think it'll be great if you put the starter and the finish code on the repo I think it's now only the completed code, a little bit hard to follow step by step Sorry for my bad English Thank you very much for the video, I learned from you a lot
15:20 won't this check toBeTruthy always pass since queryAllByText will always at least return an empty array, which is truthy? Might be better to do queryByText("Hello").toBeInDocument() or something like that?
At 15:14 - testing an array to be truthy will always return true, wouldn't it? Better to do queryByText or to check the length again if you choose queryAllByText
I notice you still use React.FC type instead of letting Typescript infer it as a JSX element. I recall there being a difference with how those types handle the children prop, but otherwise is there a benefit to explicitly typing the component? Great video though. was just about to create something similar.
React.FC or React.FunctionComponent just give you a children prop by default, which we don't use here, so we could remove that. They also set the return type which is nice because it ensures that every return path returns something valid... which is cool.
There are a bunch of different ways to handle CSS. You could use a CSS-in-JS solution (my preferred) or you could do CSS files and then bundle the CSS and include it in dist on build and dev and then bring that into the host app via an import and let Webpack bundle it.
@@jherr Thanks. We are using CSS-in-js but some of 3rd party need to import css that's time we are put that in global.css and bundle with webpack mini extract css. Nextjs otherwise giving error. What is the best approach? your saying everything one folder all components related things

@@jherr That's awesome. 👏 I often wonder if I'm just lazy or if other people have more time. I appreciate your answer as it gives me a kick to do more with my time!
I did clone the repo and run pnpm test, but I'm getting the follow error: Test suite failed to run Jest encountered an unexpected token Jest failed to parse a file.

I'm having gnarly problems getting Storybook working with a Next.js 13 project with pnpm or npm. It only seems to be less gnarly when using Yarn. As a web dev noob these paint-points are super annoying :/

I usually go with this structure except I'm using styled components with emotion and TypeScript support! it really is amazing.
Thanks for the tutorial Jack, it popped up in my UA-cam feed just when I needed it... spooky :)

Thanks so much for putting this together Jack!!! This is incredibly valuable knowledge right here.

What about the tree shaking when you build the UI? it will bring all components exported in index.ts on first JS load ?
If it's a hard npm linkage then it's up to your bundler to do final build tree shaking.
Hey Jack, what Tool use you for screendrawing?
awesome thanks!! 🙏 for you and yours!
Can you tell me what plugin you used to get hints when writing the code?
100000/100 of greatness
Great video! In your component folder structure would you have a types file in the same place?
That is one way to do it. But this video offers organization by component as opposed to by file type.
thank you so much 🌀
As of the release of React 17, there's no need to import React in react components anymore, for reference, look for: Introducing the New JSX Transform on the official react blog
If you use TS and you want to reference something like React.FC then you still need to include it.
Another beautiful video as always. I noticed that you didn't test the Storybook code, is that possible or needed?
Hi sir, thank you so much for the video, but I think it'll be great if you put the starter and the finish code on the repo
I think it's now only the completed code, a little bit hard to follow step by step
Sorry for my bad English

Just tried running npx storybook init in the packages/ui directory and it didn't blow up! Looks like that fixed that.
15:20 won't this check toBeTruthy always pass since queryAllByText will always at least return an empty array, which is truthy? Might be better to do queryByText("Hello").toBeInDocument() or something like that?
Yeah, that's true. Whoops.
Amazing!
What is the difference between pnpm and npm?
pnpm is slightly faster and has some offline caching functionality.
Amazing stuff as usual
Is it possible to keep storybook in its own separate package, and keep stories colocated with their respective components in other packages?
I've seen it done, yes.
Great! Now, how do we publish a UI Library from this to NPM? Thanks
Jack, how are you? Thank you for the video!
I’m hanging in there. Thanks for asking! FWIW, this video was shot before all this happened.
Can you please make a video on fetching data in next js from express server with a db
Do you guys prefer Jest over Testing-library?
pnpx I deprecated, use pnpm exec instead :)
I am having a problem when I wrap my components with React.memo, the props and component name don't get to set correctly, any ideas?
At 15:14 - testing an array to be truthy will always return true, wouldn't it? Better to do queryByText or to check the length again if you choose queryAllByText
You are correct. My bad on that one.
How about SolidJS with Storybook next?
谢谢！
