Bun includes a built-in shell for running shell commands from JavaScript with template literals. Cross-platform — same syntax on macOS, Linux, and Windows.
Why Bun Shell?
Bun's shell lets you write shell scripts in JavaScript with proper error handling, type safety, and cross-platform support. No more child_process.exec.
The Free APIs You're Missing
1. Tagged Template Shell
Run any shell command with Bun's dollar-backtick syntax. Variables are safely escaped — no injection risk.
2. Output Modes
Get output as .text(), .json(), .lines(), or .blob(). Parse command output natively in JavaScript.
3. Cross-Platform
Same syntax works on macOS, Linux, and Windows. Bun translates commands to the native shell.
4. Error Handling
Use .nothrow() for graceful error handling. Access exitCode, stdout, and stderr as structured data.
5. Piping
Pipe between commands and redirect to files, just like a real shell — but with JavaScript error handling.
