cache-bun

Cache bun

Sets up actions/cache for the bun cache directory (default: ~/.bun/install/cache).

Purpose

• Caches bun's package cache to speed up installs in subsequent runs.
• Exports BUN_INSTALL_CACHE_DIR via GITHUB_ENV so bun uses the same cache path in later steps.
• No-op when no bun.lock or bun.lockb file is found.
• Uses lockfile hash in the cache key for correctness.

Run after checkout; run before any bun install command.

Usage

- name: ⬇️ Checkout
  uses: actions/checkout@v4
- name: 📦 Cache bun
  uses: w5s/actions/cache-bun@main
  with:
    cache-path: .bun-cache # optional

Inputs

• cache-path (optional): bun cache directory to store/restore. Defaults to ~/.bun/install/cache.

Requirements

• Use in projects that have bun.lock or bun.lockb (bun). Bun must be available (e.g. after ci-setup).
