bun-self
v0.1.0 bun
bun-self
Let's say you have a file called script.ts
with the following content:
import { $ } from "bun";
await $`curl -s wttr.in`;
And you really want your friend to run it, so you decide to share a gist with them, but they are not as cool as you and don't have Bun installed yet. A problem.
But you won't even believe what happens next:
bunx bun-self script.ts
And you send this beauty to your friend instead (script.run.ts
):
#!/bin/sh
/*/.this-doesnt-exist 2>/dev/null
## Please do not edit this part of the script, this is a loader created by "npx bun-self"
if ! [ -x "$(command -v bun)" ]; then
echo "Installing bun.sh"
sleep 2
curl -fsSL https://bun.sh/install | bash
export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"
echo "Now let's run the script"
echo ""
fi >&2
bun "$0"
exit 0
#*/
// Script starts here
import { $ } from "bun";
await $`curl -s wttr.in`;
Your friend just has to run it either with
bash script.run.ts
or
chmod +x ./script.run.ts
./script.run.ts
They won't even know what hit them.
Of course it doesn't have to be a friend, you can hide that stuff in plain sight at your job with an innocent-looking "bash script.run.ts" in the "scripts" section of your package.json and no one even will notice that they are now happy Bun users.
