Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Mastering Jest Configuration for React TypeScript Projects with Vite: A Step-by-Step Guide
//config/jest/setupTests.ts // jest-dom adds custom jest matchers for asserting on DOM nodes. // allows you to do things like: // expect(element).toHaveTextContent(/react/i) // learn more: https://github.com/testing-library/jest-dom import '@testing-library/jest-dom';

Anyone have setup instructions for Vitest + Typescript + React testing library? My setup is failing to extend matchers on Vitest Types
Update: Just got it working. Following the instructions on this github issue and using `shamefully-hoist=true` with pnpm I got it working. The issue I was facing was with pnpm.

Is there a jest query method for this use case?
React Testing Library uses jest-dom which has a .getByText() matcher.

Setting Up a Modern Preact Application With Typescript, Vite and Vitest
vitest-dom extends the standard Jest matchers with convenient methods like .toBeDisabled. Now you can write tests that assert on the state of the DOM. The package is a fork of @testing-library/jest-dom.

Migrating from Jest to Vitest
At the time of writing this article, it still seems to be an open issue. However, a workaround I found is to add "skipLibCheck": true, to your tsconfig.json file.

Setup Jest to React Typescript Vite project, also SWC (part 1)
Everything you want to do to your test environment such as extends the jest matchers with @testing-library/jest-dom, mock some APIs that’s not implemented in jdom, you can put to config/jest/setupTests.js:
-
Svelte test suite setup
This will register the additional assertions from @testing-library/jest-dom.

Creating mocks for testing react code
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.

Storybook 8
> 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!
