Development
This project uses Bun for package management, tests, and scripts. Packages are still published to npm as ESM-only libraries.
Prerequisites
Install Bun 1.3.14: https://bun.sh/docs/installation
Node.js 24 is pinned in .nvmrc for npm package validation and OIDC publishing; Bun remains the workspace package manager and test runner.
Install, build, test
git submodule update --init --recursive
bun install
bun run build
bun run test
Lint and format with Biome:
bun run check
Publishing
Releases still go through Changesets and publish to npm (OIDC). Merging to main opens a Version Packages PR; merging that publishes.
