bun-runtime
Provides Bun runtime helpers to run shell commands, perform filesystem reads/writes, globbing, and HTTP requests via scripts/bun-process.sh, scripts/bun-fs.sh, scripts/bun-glob.sh, and scripts/bun-fetch.sh. It enables executing arbitrary shell commands (OUTPUT=$(eval "$COMMAND") and making fetch requests to arbitrary URLs (e.g., https://api.example.com), allowing unrestricted command execution and remote network access.
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
