msw VS storybook

We’re going to use Mock Service Worker (MSW) for mocking network requests in our integration tests and in the app during development.

However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.

While mocks are effective, they require modifying the component's internal logic or mocking global functions like fetch. This can become cumbersome for complex components with numerous API interactions. Here's where MSW shines.

> For those wondering what the use case is, you must not have tried it. It does take work to set up (with each version that's less), but it can be very nice to test in isolation esp in cases where a component is under a login, the 4th page of a 10 page form, etc. Also obviously if you're working on a component library that ships without an app, Storybook can be your development and/or demo app.

I have worked with storybook extensively over the past couple of years and my team is moving away from it in favour of MSW (https://mswjs.io).

For "4th page of a 10 page form" during the development there's hot reloading which is really stable nowadays and haven't failed me, although I understand that some setups are old and it might be easier to configure Storybook than good hot reloading.

I'm not entirely sure about the testing part of it and I'd be grateful if you could elaborate. I haven't felt the need for some special setup with SB because for unit tests, I can test a deeply nested component separately. For E2E tests, I usually test the whole form.

I agree on the component library part, this is probably the only use case where Storybook is 100% justified, but I'm unconvinced about the

Additionally, thank you to all our community launch partners across the frontend ecosystem for helping us bring Storybook 8 to the world!

similar with msw.js, but fully automated

they could be network mocks (use msw)

With orval, we can also integrate the API client in our unit tests. Orval provides first class support for mocking through the (Mock Service Worker)[https://mswjs.io/] library, and it can automatically generate the MSW handlers for testing server.

Consider a hypothetical scenario where data from a list of companies within an ERP needs to be retrieved. As a personal recommendation, leverage tools like MSW for top-level mocks, which can significantly enhance the testing process.

As a development server, we can use an actual development server of our app, like Create React App (that we use for the examples) or Vite, or another tool like React Styleguidist or Storybook, to test isolated components.

[Bug]: Configuration with TailwindCss Next.js using Tailwind with Storybook

Astro has no runtime. This means no unit tests. This also means no Storybook for your Astro components (although, they’re working on it!)

If you're into UI development, then you need to know about Storybook. It's a frontend workshop for building UI components and pages in isolation. The latest version brings some big improvements for testing and documentation with built-in visual testing. There's also React Server Component support, improved controls for React and Vue projects, as well as improved Vite architecture, Vitest testing, and Vite 5 support. Check out all the major changes in the Storybook changelog.

Storybook

We are continuing to make building fullstack websites and application with Analog and Angular as seamless as possible, and extending the Angular ecosystem through integrations with Astro, Nx, [Vitest]https://analogjs.org/docs/features/testing/vitest, Storybook, and more.

Storybook is the industry standard UI tool for building, testing, and documenting components and pages. It’s used by thousands of teams globally, integrates with all major JavaScript frameworks, and combines with most leading design and developer tools.

Expo has first-class support for building full-stack websites with React, so I can leverage that to add Cypress/Playwright for E2E testing and add the Storybook for UI components.

Storybook emerges as a pioneering solution among React debugging tools, offering an interactive environment for developers to create and test UI components. With its robust platform, teams can build, organize, and design UI components, and even entire screens, without the hurdles of business logic and plumbing.
