To update or switch versions, run webi bun@<tag>.
(you can use @beta for pre-releases, or @x.y.z for a specific version)

These are the files / directories that are created and/or modified with this install:

~/.config/envman/PATH.env
~/.local/opt/bun/
~/.local/opt/bun-<VERSION>/

Bun is a wicked-fast JavaScript runtime for developer tooling, API servers, and edge computing.

It's built in Zig and provides a more curated, "batteries-included" approach to developing with JavaScript and JavaScript-ish languages - such as TypeScript, JSX, and TSX.

Run some xScript:

bun run ./hello.js
bun run ./hello.jsx
bun run ./hello.ts
bun run ./hello.tsx

Run a package from npm:

bun x jswt

More goodies:

bun help

(there's also a built-in development server and lots of stuff)

Bun has an official installer:

export BUN_INSTALL="$HOME/.bun"
curl -fsSL https://bun.sh/install | bash

You might want to still use webi if you want to be able to switch between versions.

bun completions

1. Create your script

   vim ./hello

   #!/usr/bin/env bun
   console.log('hello');

2. Make it executable

   chmod a+x ./hello

3. Run it

   ./hello

At the time of this writing (bun v0.5.1), you'll still need to publish with npm.

npm is installed with node.

See Getting Started with NPM (as a developer).

You can run it with bun x:

bun x <whatever>

Or you can put the #!/usr/bin/env bun shebang before publishing, and install from npm:

bun install -g <whatever>
<whatever>

As a system service on Linux:

(note: swap 'my-project' and './my-project' for the name of your project and file)

1. Install serviceman (compatible with systemd)

   webi serviceman
   source ~/.config/envman/PATH.env

2. Go into your program's directory

   pushd ./my-project/

3. Add your project to the system launcher, running as the current user

   sudo env PATH="$PATH" \
       serviceman add --path="$PATH" --system \
           --username "$(whoami)" --name my-project -- \
       bun run ./my-project.js

4. Restart the logging service

   sudo systemctl restart systemd-journald

For macOS:

1. Install serviceman (compatible with launchctl)

   webi serviceman
   source ~/.config/envman/PATH.env

2. Go into your program's directory

   pushd ./my-project/

3. Add your project to the system launcher, running as the current user

   serviceman add --path="$PATH" --user --name my-project -- \
       bun run ./my-project.js
