Setting your Bun Version

Bun is an all-in-one toolkit for JavaScript and TypeScript apps. Bun version 1.1.0 is the current default for Render services.

You can customize your service’s Bun version by setting the BUN_VERSION environment variable to a valid version number, such as 1.1.30.

To use the most recent version of Bun with every deploy, set BUN_VERSION to latest.
