qnm: A CLI Tool to Look Into

— If you’ve been into a

folder and been overwhelmed, this tool (supporting both npm and Yarn) lets you dig around with extra guidance as to what is what. You can use fuzzy search to find specific things, and also see which modules are using the most space (you could try that right now with

).

🛠 It must be the week for testing, as endpts has shared a thorough built-in test runner primer too, and NearForm’s Rômulo Vitoi takes it a step further by showing us how to build a custom test reporter.

IN BRIEF:

• Somehow we missed it, but Node.js recently turned 14 years old with the initial release being on May 27, 2009.

• As of June 1, Node.js 19 is now ‘end of life’ and will not receive further updates.

• 📄 Ohm, Pohl and Boes published an academic paper titled You Can Run But You Can’t Hide: Runtime Protection Against Malicious Package Updates for Node.js. They approached the long-standing issue around supply chain security with a technique to automatically limit the capability of packages at runtime with 90% success and little overhead.

• Alternative server-side JavaScript runtime Bun has added an interesting ‘macro’ feature to its new bundler. This might catch on.

• MDN’s reference pages on regular expressions in JavaScript have been substantially improved.

🛠 Code & Tools

bundlejs: npm Package Bundle Size Checker — A browser-based tool that can treeshake, bundle, minify, and compress (gzip and brotli) packages to show you what their weight impact is. It runs entirely in the browser, too, using the WebAssembly build of esbuild.

Prisma-Lint: A Linter for Prisma Schema Files — The team behind this tool has dozens of schema files to stay on top of, so they built this to maintain a consistent style and ensure they have the proper indices in place.

Loop Payments

copy-paste: Cross-Platform Clipboard Copy/Paste — Wraps around different utilities for each operating system (macOS, Linux, BSD, and Windows).

Actio: A Framework for Backend Apps — A framework that ‘blurs the line’ between microservices and monoliths giving the flexilibity to experiment with your approach. Comes with a few ‘batteries included’ services for areas like auth, file upload support, configuration, and payments. (Examples.)

Crufters

DOT Classes: TypeScript Library to Model Data Transfer Objects — Designed to model data transfer objects in HTTP JSON APIs using class-based schemas that serialize/deserialize, static types by default, custom validation support, and an API that may feel familiar if you use OpenAPI and JSON Schema.
