Bun Runtime

Native Bun runtime operations for filesystem, process, and network tasks.

When to Use

Use this skill when:

• Working with Bun's native file APIs (Bun.file(), Bun.write(), Bun.glob())

• Need optimized I/O operations in Bun environment

• Running Bun-specific process commands

• Making network requests with Bun's fetch

Filesystem Operations

Read File

scripts/bun-fs.sh read /path/to/file.txt

Returns JSON: {"content": "file contents"}

Write File

scripts/bun-fs.sh write /path/to/file.txt "content here"

Creates parent directories automatically. Returns JSON: {"written": true, "path": "/path/to/file.txt"}

Glob Files

scripts/bun-glob.sh "/tmp/*.txt"

Returns JSON: {"files": ["/tmp/file1.txt", "/tmp/file2.txt"], "count": 2}

Process Operations

Execute Command

scripts/bun-process.sh "ls -la"

Runs shell command and returns output.

Network Operations

HTTP Request

scripts/bun-fetch.sh "https://api.example.com" "GET"

Makes HTTP request using Bun's native fetch.

Notes

• All scripts use Bun's native APIs for better performance

• File operations automatically handle encoding

• Errors are returned with clear messages
