📋 Available Bun Packages

debian.griffo.io provides three different Bun packages to suit different needs:

🥟 bun (Recommended)

Metapackage that automatically installs the latest stable bun-one. This is the recommended choice for most users as it ensures you always get the latest stable release.

sudo apt install bun

🚀 bun-one

Latest stable release of Bun runtime. This package contains the production-ready version with optimizations for performance and stability.

sudo apt install bun-one

🔍 bun-profile

Profiling-enabled build of Bun with debugging symbols and profiling capabilities. Ideal for development, debugging, and performance analysis. Slightly larger binary with additional debugging information.

sudo apt install bun-profile

🔄 Managing Multiple Bun Versions

You can install both bun-one and bun-profile simultaneously and switch between them using Debian's update-alternatives system:

Install both versions:

sudo apt install bun-one bun-profile

Configure alternatives (done automatically during package installation):

sudo update-alternatives --install /usr/bin/bun bun /usr/bin/bun-one 100
sudo update-alternatives --install /usr/bin/bun bun /usr/bin/bun-profile 90
            

Switch between versions interactively:

sudo update-alternatives --config bun

Check current version:

bun --version
which bun
            

步骤 2：安装 Bun

sudo apt install bun

apt install bun

Step 3: Verify Installation

bun --version
bun --help
            

🚀 Quick Start Examples

Create a new project:

mkdir my-bun-app && cd my-bun-app
bun init
        

Install packages (faster than npm):

bun install express
bun add -d @types/express
        

Run TypeScript directly:

echo 'console.log("Hello from Bun!")' > app.ts
bun run app.ts
        

Bundle for production:

bun build ./app.ts --outdir ./dist --minify

Run tests:

bun test

🔧 Configuration

Bun can be configured using a bunfig.toml file in your project root or home directory:

# bunfig.toml
[install]
# Configure package manager behavior
cache = "~/.bun/install/cache"
registry = "https://registry.npmjs.org"

[run]
# Configure script runner
shell = "bash"

[test]
# Configure test runner
preload = ["./setup.ts"]
