Appwrite Sites now supports Bun (1.0, 1.1, 1.2, 1.3) and Deno (1.40, 1.46, 2.0, 2.5, 2.6) as build runtimes for every Node-based framework.
Switch the build runtime per site under Site settings, in the Runtime settings section. The change applies on the next deployment, your active deployment is not affected until you redeploy.
