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.

Storybook 8 Beta
First, we switched the default compiler for new projects from Babel to SWC (Speedy Web Compiler). SWC is dramatically faster than Babel and requires zero configuration. We’ll continue to support Babel in any project currently using it.

Implementing auth flow as fast as possible using NestJS
As the reference explains “**SWC** (Speedy Web Compiler) is an extensible Rust-based platform that can be used for both compilation and bundling. Using SWC with Nest CLI is a great and simple way to significantly speed up your development process.”

Ruby Outperforms C: Breaking the Catch-22
This is specifically about breaking the myth that performing expensive self-contained operations (e.g, parsing GraphQL) in a native extension (C, Rust, etc.) is always faster than the interpreted language.
The JS ecosystem has the same problem, people think rewriting everything in Rust will be a magic fix. In practice, there's always the problem highlighted in the post (transitioning is expensive, causes optimization bailouts), as well as the cost of actually getting the results back into Node-land. This is why SWC abandoned the JS API for writing plugins - constantly bouncing back and forth while traversing AST nodes was even slower than Babel (e.g https://github.com/swc-project/swc/issues/1392#issuecomment-...)

FTA: Fast TypeScript Analyzer
FTA is a TypeScript static analysis tool built on the speedy foundations of swc. FTA is fast; capable of analyzing more than 150 files per second on typical hardware, it offers a powerful addition to your code quality toolkit.

Show HN: Ezno, a TypeScript checker written in Rust, is now open source
Very cool! I'm curious, is this intended for dev tooling?
For example, I could see this (or something similar) being useful as the engine for a typescript language server that would be faster than the standard one
But if it's not aimed at 1:1 with tsc, would it be intended more for something like swc[1]?
Or what would you expect people to use this for, besides just being a cool project to learn from?

TypeScript team released an explorer for performance tuning
This is... good news, but I still cannot fathom using the default Typescript compiler for regular development. Seriously, leave the type-checking to your IDE and CICD chain, and switch to using tsx (https://www.npmjs.com/package/tsx) or swc (https://swc.rs/) and you will _immediately_ notice the difference in speed and productivity.
