Warning

Bun is not recommended for gateway runtime (known issues with WhatsApp and Telegram). Use Node for production.

Bun is an optional local runtime for running TypeScript directly (bun run ..., bun --watch ...). The default package manager remains pnpm, which is fully supported and used by docs tooling. Bun cannot use pnpm-lock.yaml and will ignore it.

Install

Install dependencies

```sh
bun install
```

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

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

Build and test

```sh
bun run build
bun run vitest run
```

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 defaults to Node 24 and still supports Node 22 LTS, currently 22.19+)
• protobufjs postinstall -- emits warnings about incompatible version schemes (no build artifacts)

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

bun pm trust baileys protobufjs

Caveats

Some scripts still hardcode pnpm (for example check:docs, ui:*, protocol:check). Run those via pnpm for now.
