What Hacker News says

4 sources
I don’t know what you mean. I have dozens of stories showing components of all layers in the hierarchy. I have single button stories, stories for entire views, stories of entire apps. And storybook allows to show the code of stories, which is equivalent to a « getting started » or usage example for each of these components in docs. Except that it is guaranteed to be evergreen, since if these examples break, my CI wouldn’t pass. Labelflow is a public repo I manage with storybooks like that. We use Chromatic with storybook in there. Search for folders named « __stories__ » for stories at all level of the hierarchy. https://github.com/labelflow/labelflow
In Storybook: UI component explorer for front end developers
I’ve used storybook for 4-5 years (basically since day one) in teams of 1-15 devs and I’d say it’s a must have for any serious react app with 3+ full time developers. It has its rough edges sure but the ROI is 10x nonetheless in my experiences. Advantages - Testing components in isolation forces some good practices and allows to keep the codebase in check by encouraging good practices (limited coupling of unrelated parts of the codebase - It’s super productive because it is both a form of unit tests, useful during development of UX in « TDD mode », and a very good documentation of your UI components. It greatly reduces the effort needed for both these aspects. - For DX, the hot reload is generally faster in storybook than in the App (except if you use vite/snowpack in your app, so far..) because reloading a single component is faster than

reloading the whole app and its state. In a large CRA our hot reload could sometimes take up 1min in complex cases, while storybook was taking 3s. - Coupled with Chromatic (their hosted platform) and its GitHub integration it makes QA and visual regression testing a joy, 10x faster than alternatives, I really recommend that. - It allows to share/iterate easily your ongoing developments with non-tech people in your organisation at early stage. A very good bridge between Figma and the final UI. A good support during Daily meetings about UI, just share the deployed story url to ask for feedback. Drawbacks - It has its own Webpack config. So if you have a custom Webpack config in your app (don’t do that anyway, unless absolutely necessary) then be prepared to duplicate the customizations in your storybook config - Global React Contexts needs to be duplicated in your storybook config and, if necessary, configured for individual stories. For example if your signup button changes based on an Auth status stored in a global context, then you will have to use Story.parameters to customize the content of the Auth context. - We had a couple instances where storybook was the limiting factor for us to embrace some new/fancy tech, like yarn v2 or service worker. However maybe that’s a good litmus test: things that storybook support are state of the art JS and generally safe to use. Things that storybook does not support out of the box will cause you problems with other tools anyway: if it’s not storybook, some other tool like Cypress, Jest, Next, or some browsers will cause you trouble with your “shiny new tech” - It can be slow to startup. We had a storybook with 300+ complex stories and it took 5min to startup and 10min to build in the CI - It had some API changes/ migration pains a couple years back. However I think the new API is very good and will last a long time so this is behind. Overall I definitely advocate to use storybook, especially with Chromatic, the ROI is 10x. If you find yourself limited by it in 2021 despite configuring it, maybe question your own tech stack. Don’t try to implement your own storybook copycat (we had a colleague develop an alternative https://github.com/remorses/vitro , but i think it was not worth the effort) If you want to see a state of the art monorepo in NextJS that uses storybook extensively with some customizations, check https://github.com/Labelflow/labelflow/
In Storybook: UI component explorer for front end developers
4 months ago we announced Labelflow (https://www.labelflow.ai/), the open image annotation and dataset cleaning platform. What was then just a landing page is now a product that you can try for free with no login required, the code is also publicly available on GitHub. (https://github.com/Labelflow/labelflow/). In this first version, we are releasing your most wanted features: a straightforward online image annotation tool. For privacy concerns, your images are never uploaded to our server! You can create bounding boxes, polygons, export labels to COCO format and we added plenty of keyboard shortcuts for productivity! We’re excited to hear your feedback, tell us what features would make your life easier (https://labelflow.canny.io/feature-requests) and upvote what you would like us to build. Stay tuned, It’s just the beginning of a long
