JSIR: A High-Level IR for JavaScript from Google — Google has open sourced a new tool (JSIR) and proposed an industry-standard IR (Intermediate Representation – if an AST tells you what the code looks like, an IR tells you what it does) for JavaScript. Already used at Google for analysis and code transformation, the underlying idea could form a foundation for a new generation of tooling.

Minimum Release Age is an Underrated Supply Chain Defense — An increasingly common package manager feature is being able to specify a minimum ‘package age’. The idea is that if you wait, then maintainers, security tools, etc. will tackle the most nefarious supply chain attacks. It’s no silver bullet, but may suit your use case, and here’s how to set it up.

A new, major npm supply chain attack via Axios

axios Package Compromised; Malicious Versions Added a Trojan Dependency — Axios is an HTTP library that gets 100M+ downloads a week, largely due to its legacy popularity. An attacker took advantage of that to roll out a version with a malicious dependency including a remote access trojan (though Axios' codebase itself was fine). This is big, as even if you don’t use Axios, your dependencies might. Here's how to see if you're affected.

💡 More: Socket offers a more accessible breakdown. There's also a GitHub issue discussing the matter. It's worth considering pinning your dependencies, preventing post-install scripts from running (can be configured with npm but is the default in pnpm and Bun) and/or using cooldowns for dependency updates (using minimumReleaseAge in npm or pnpm's approach).

JavaScript Weekly

Announcing TypeScript 6.0 — Over six months in the making, TypeScript 6.0 is designed to bridge the gap between its self-hosted compiler and the (almost ready) Go-powered native compiler of TypeScript 7.0 . There are new features (Temporal improvements, RegExp.escape, and more), but most important are the changes to help you prepare for 7.0:

Numerous default changes: strict is now true, module is esnext, rootDir defaults to ., and more.
A change that will affect many apps is types defaulting to [] rather than pulling in everything from node_modules/@types.
Numerous deprecations: the es5 target, emitting AMD, UMD, and SystemJS modules, --baseUrl, and others.
--stableTypeOrdering makes 6.0's type ordering behavior match 7.0's to help diagnose inference differences as you update.
