## What it is
|
|
|
|
Bun runs JavaScript and TypeScript, like Node.js, and also installs packages, bundles code and runs tests, all from one binary. It aims to work as a drop-in replacement for Node.js in most projects, and runs TypeScript files directly without a separate build step.
|
|
|
|
## Why it's here
|
|
|
|
- **Fast installs.** `bun install` reads `package.json` and installs dependencies much faster than npm.
|
|
- **TypeScript without setup.** `bun run file.ts` just works.
|
|
- **Fewer tools.** Runtime, package manager, bundler and test runner in one.
|
|
|
|
## On CoreDesktop
|
|
|
|
Bun is installed from pacman, alongside Node.js, so you can use either per project. `update` keeps it current with the rest of the pacman packages.
|
|
|
|
```
|
|
bun run index.ts
|
|
```
