Bun runtime

[yantakus]

Hi there. Thanks for working hard on Convex!

Is there a plan to support bun runtime?

Inspired by next.js support of bun runtime (https://bun.com/docs/guides/ecosystem/nextjs) I've just tried to run convex with bun run --bun convex dev and immediately run into

✖ Error fetching POST  http://127.0.0.1:3210/api/deploy2/start_push 400 Bad Request: DeploymentNotConfiguredForNodeActions: Hit an error while pushing:
Deployment is not configured to deploy "use node" actions. Node.js v18, 20, or 22 is not installed. Install a supported Node.js version with nvm (https://github.com/nvm-sh/nvm) to deploy Node.js actions.

error which is absolutely obvious, because it checks for node version which is missing at all.

What about "use bun" :)

Bun's API is 100% compatible with node.js, so it seems to be pretty straightforward (I might be wrong, don't blame me if not :)

Hi - there's no plan.

Seems like a not-crazy idea. Feel free to fork and try to get it working while self-hosting and share what you figure out.

We're probably going to be pretty slow to move on getting it into the cloud product - because we would want to battle test an option like that. We're probably going to spend more effort getting the Convex runtime working better in more scenarios. But very excited about folks trying to get it working on their own and reporting back.
