Puppeteer 24 – Popular high-level API to control Chrome or Firefox.
Cypress 14 – Easy testing for anything that runs in a browser. Now supporting the latest versions of React, Angular, Svelte & Vite for component testing.

react-nil 2.0: A React ‘Null Renderer’ — An interesting experiment to use React in situations where you don’t need it to render anything, but you want to use hooks, suspense, context, and other bits of the React lifecycle. Like in, say, a Node app. Maybe this CodeSandbox example will provoke some ideas.

🔎file-type 20.0: Detect the File Type of a File, Stream or Data — For example, give it the raw data from a PNG file, and it’ll tell you it’s a PNG. Uses a ‘magic number’ approach so is targeted at non text-based formats. v20 adds support for yet more formats, including JARs, Word/Excel templates, and now supports ZIP decompression.
