It’s been 4 years since TypeScript schema validation library Zod released v3, but the new v4 release makes it worth the wait. Expect faster parsing times across the board, built in error pretty-printing, and even a tree-shakeable API called Zod Mini for constrained environments like edge runtimes.

There’s a new npm-based CLI tool for managing and sharing AI rules across different editors and tools called vibe-rules. In addition to saving favorite prompts so they can be applied to any supported editor, vibe-rules can also automatically install prompts shared in a project’s NPM packages into an editor’s configuration. It’s early days yet, but a great idea to make prompts easier for anyone to use.

Angular v20 is out with some much anticipated highlights. Stabilized signal-based APIs, incremental hydration, custom Angular reporting directly in Chrome DevTools, GenAI development advancements, and, last but not least, a RFC for an official Angular mascot. Not to bias you, but we favor the pink, dice-shaped mascot around here.
