**Migration from Node**: Replace `node script.js` with `bun run script.js` or `bun script.js`. Run `bun install` in place of `npm install`; most packages work. Use `bun run` for npm scripts; `bun x` for npx-style one-off runs. Node built-ins are supported; prefer Bun APIs where they exist for better performance.

**Package and workspace commands**: `bun add <pkg>` / `bun remove <pkg>` / `bun update [pkg]` manage dependencies; `bun outdated` lists stale deps; `bun pm ls` shows the dependency tree derived from the lockfile (not a listing of what's actually on disk). Read-only inspection: `bun audit` reports known vulnerabilities. Modifying: `bun audit fix` applies fixes, `bun dedupe` collapses duplicate installs, and `bun prune` removes packages no longer referenced. Monorepos use a root `workspaces` array in `package.json` (same convention as npm/yarn); run a script in one workspace with `bun run --filter <pkg-name> <script>`.

For CI, Bun 1.4's test runner adds: `bun test --changed[=<ref>]` (run test files affected by changes vs. a git commit/branch — includes tests exercising changed source files, not just edited test files), `bun test --isolate` (fresh global object per test file, so leaked handles in one file can't affect another; implied by `--parallel`), `bun test --parallel[=<n>]` (run test files across N worker processes, defaults to CPU core count), `bun test --shard=<n>/<count>` (split one suite across CI runners), and `bun test --timings=<file>` (reads JSON per-file duration data to front-load the slowest files) with `--update-timings` (writes to the first `--timings` path given — without `--shard` it merges into existing entries; with `--shard` it writes only the current shard's files to that same first `--timings` path — Bun does not pick a different path per shard automatically, so choose a distinct output path for each shard to avoid overwriting other shards' timing records; pass `--timings` multiple times, once per shard file, to read them together as a single combined table). Example: `bun test --parallel --timings=./test-timings.json --update-timings`. Run `bun test --help` locally to confirm exact flag behavior for your installed version.
