🤟 Node.js Toolbox: A Way to Find and Compare Node.js Packages A fantastic community maintained resource that presents a category-based way to find packages and libraries. For example, you can check out HTTP frameworks, browser testing, query builders, and more. You can compare libraries in various ways, see their download count, or edit/submit listings yourself.

SPONSORED BY Lantern Cloud 👯‍♀️ Vector database on top of Postgres for AI 🤔 JS-PyTorch: A PyTorch-Like Library for JavaScript Recently renamed from JS-Torch, this brings some of the magic from Python’s popular PyTorch library to JavaScript for training and testing neural networks in particular. We linked to it earlier this year, but it has added GPU support thanks to GPU.js. Eduardo Leao
