Trigger.dev runs your tasks on specific Node.js versions:

### v3

- Node.js `21.7.3`

### v4

- Node.js `21.7.3` (default)
- Node.js `22.16.0` (`node-22`)
- Bun `1.3.3` (`bun`)

You can change the runtime by setting the `runtime` field in your `trigger.config.ts` file.

```ts
import { defineConfig } from "@trigger.dev/sdk";

export default defineConfig({
  // "node", "node-22" or "bun"
  runtime: "node-22",
  project: "<your-project-ref>",
});
```
