Bun runtime patterns. Use when running bun commands, working with package.json/bun.lock, writing TypeScript scripts under Bun, or developing Claude Code plugins.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Bun

## bunx

Put `--bun` before the executable name to force the Bun runtime over Node shebangs. Use `-p`/`--package` when the binary name differs from the package name (e.g., `bunx -p @angular/cli ng`).

See [references/bunx.md](references/bunx.md)

## Lockfile

`bun.lock` is a text-based lockfile. Resolve merge conflicts by regenerating it from `origin/main` with only the resolved manifests applied, never by hand.

See [references/lockfile.md](references/lockfile.md)

## Resolution

Runtime flags must precede the script path: `bun --cwd ./packages/app run dev`. Never use `.js` extensions in TypeScript imports — Bun resolves them natively.

See [references/resolution.md](references/resolution.md)

## Shell

`Bun.$` is a tagged template for shell execution. Use response methods (`.text()`, `.json()`, `.lines()`) to extract output, `.nothrow()` to handle failures without exceptions, and pipe/redirect syntax to compose commands.

See [references/shell.md](references/shell.md)

How to install

The exact contents, by fingerprint
mdr add bendrucker/claude/bun@sha256:59fa081b3cbc62c8

The line at the top of this page pins the label git:20261030.ee8bb41, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
