bun --canary

[vjpr]

It's annoying to have to bun upgrade --canary and then bun upgrade --stable if there is a bug.

It would be nice to be able to use a flag to control which bun version is used.

Some ideas:

bun --canary
bun --channel=canary
bun --revision=1.2.2+c1708ea6a

BUN_CHANNEL=canary bun

I use a personal script I wrote called js to control which bun runtime to use because there are still occasions I need to use node because of a bug.

Example usage in shell script for cli app. You then use env vars to control which js runtime and which version to be used.

#!/usr/bin/env js

import('src/cli.ts')

FYI: Bun download logic seems to be here if needed: https://github.com/oven-sh/setup-bun/blob/main/src/action.ts

Btw you can use bunx bun-pr <commit-hash> and if it has built a canary in CI for it, then it'll download and you can use it like bun-<commit-hash> run ./index.ts

It's intended to be discouraged for actual normal use because you should be using latest Bun (and esp not a random commit). I only use this when trying to find which commit regressed, otherwise I try to keep latest canary locally (or stable if production normally).
