μ Sandbox

μ provides a secure environment for executing JavaScript code with WebAssembly-based isolation. This documentation covers all aspects of using the sandbox, from basic setup to advanced security features and API integrations.

Basic Usage

Open the sandbox in your browser and start writing JavaScript code immediately. No setup required.

Security Requirements

By default, μ enforces:

• • Memory-isolated execution
• • No network access
• • Restricted filesystem access
• • Real-time execution monitoring

Code Execution Example

// Open in μ Sandbox:
function main() {
  console.log('Secure execution environment')
  return 'Hello from sandbox!'
}

main()
                    

μ provides enterprise-grade security through:

Isolation Features

• • WebAssembly-based runtime
• • Memory-protected execution
• • No privileged system access

Threat Detection Features

• • Real-time execution monitoring
• • Automatic resource limits
• • Sandboxing violations detection

Sandbox Methods

• run(code: string): Execute JavaScript code in secure sandbox
• clear(): Clear current execution context
• getStats(): Get last execution performance

Example API Integration

const { run } = require('@microsandbox/runtime')

try {
  const result = run("console.log(1+2)")
  console.log(result)
} catch (e) {
  console.error('Execution error:', e)
}
                    

• Always test code in sandbox before production systems
• Never execute untrusted code without thorough inspection
• Use resource limits for all untrusted code execution
• Monitor execution stats for performance anomalies
