Bun remains usable as an optional dependency installer and package-script runner. The default package manager remains pnpm, which is fully supported and used by docs tooling. Bun cannot use pnpm-lock.yaml and ignores it.

Install

`bun.lock` / `bun.lockb` are gitignored, so there is no repo churn. To skip lockfile writes entirely:

```sh
bun install --no-save
```

Commands that launch OpenClaw itself must still run through Node.

Lifecycle scripts

Bun blocks dependency lifecycle scripts unless explicitly trusted. For this repo, the commonly blocked scripts are not required:

• baileys preinstall: checks Node major >= 20 (OpenClaw requires Node 22.22.3+, 24.15+, or 25.9+, with Node 24 recommended)
• protobufjs postinstall: emits warnings about incompatible version schemes (no build artifacts)

If you hit a runtime issue that needs these scripts, trust them explicitly:

bun pm trust baileys protobufjs

Caveats

Some package scripts hardcode pnpm internally (for example check:docs, ui:*, protocol:check). Running them via bun run still shells out to pnpm, so just run those via pnpm directly.
