build: update action runtime to Node.js 24 by adam0white · Pull Request #176 · oven-sh/setup-bun

adam0white · 2026-03-11T16:19:27Z

GitHub Actions is deprecating Node.js 20, with Node 24 becoming the default
runner on June 2, 2026. This updates setup-bun to run on the Node 24 runtime.

Changes:

action.yml: node20 → node24
esbuild target: node20 → node24
@types/node: ^20 → ^24
@actions/* deps bumped to their Node 24-compatible versions (highest CJS-compatible releases, avoiding the ESM-only latest)

Notes:

The @actions/* packages were pinned to the highest CJS-compatible versions (core@2, cache@5, tool-cache@3, etc.) since esbuild outputs CJS. The next majors (core@3, cache@6) are ESM-only.
Other actions (checkout, cache, setup-node) shipped this as a new major.

The @actions/* bumps also resolve the punycode deprecation warning (DEP0040) that Node 24 triggers with the older dependency chain.

Closes #172
Related: #173, #174, #175

Test plan

bun test — 56 pass, 6 pre-existing fail (same as main)
bun run build — reproducible (identical checksums on rebuild)
bun run format — all files unchanged
Source audit: zero Node 24 deprecated APIs in use
CI matrix (ubuntu/macos/windows) validates on PR 🤞

I'm still getting this warning

Node.js 20 actions are deprecated.

Even though I'm using

      - name: Setup Bun
        uses: oven-sh/setup-bun@v2

can't reproduce that - https://github.com/oven-sh/setup-bun/actions/runs/23085358972

actions/checkout@v4 still targets Node 20, which GitHub Actions now force-runs on Node 24 with a deprecation annotation. v5 through v7 all ship runs.using: node24 natively (checked action.yml on each tag); v7.0.1 is the current release. oven-sh/setup-bun@v2 is unaffected: it's a floating major tag that already resolves to v2.2.0, which moved to node24 in PR oven-sh/setup-bun#176.
