To install Bun, open your terminal and run

npm install -g bun

If you don’t have Node.js installed yet, check out other installation options

After the installation you’ll have two commands available: bun and bunx.

You’ll use bunx to install and directly run packages. If you know or used npx, that’s the same thing.

For everything else, you’ll use the bun command.

We’ll see more about it, but if you type just bun you’ll see an overview of how to use it.

Use bun --help to see a more detailed list of flags you can use.

And just so you know, you can upgrade Bun by running bun upgrade.
