## Sourcemaps

JS-bundle sourcemap generation mirrors rolldown's native `output.sourcemap` API:

| `sourcemap` | Emits | `sourceMappingURL` comment | Use when |
|---|---|---|---|
| `true` (default) | separate `.js.map` file | yes | OSS libraries — full debuggability |
| `'hidden'` | separate `.js.map` file | **no** | Closed-source: ship maps to error-reporting service (Sentry, etc.) without leaking via the bundle |
| `'inline'` | base64 map embedded in `.js` | n/a | Very small bundles, simpler deploy |
| `false` | nothing | n/a | You explicitly don't want maps |

```js
// vl-tools.config.mjs — privacy without losing debuggability
export default {
build: {
sourcemap: 'hidden',
},
}
```

DTS output never includes sourcemaps (declarations don't need them).

## Advanced Build Options

For non-library builds such as Chrome extensions, CLI tools, serverless functions, or Electron apps, you can bypass the `package.json`-driven pipeline with explicit configuration:
