@edge-runtime/vm

Execute JavaScript Code

This feature allows you to execute arbitrary JavaScript code within a secure and isolated virtual machine context.

const { EdgeVM } = require('@edge-runtime/vm');
const vm = new EdgeVM();
const result = vm.run('2 + 2');
console.log(result); // 4

Sandboxed Environment

You can create a sandboxed environment with predefined global variables, ensuring that the executed code does not have access to the outer scope.

const { EdgeVM } = require('@edge-runtime/vm');
const vm = new EdgeVM({ sandbox: { foo: 'bar' } });
const result = vm.run('foo');
console.log(result); // 'bar'

Timeouts and Resource Limits

This feature allows you to set execution timeouts and resource limits to prevent infinite loops and excessive resource consumption.

const { EdgeVM } = require('@edge-runtime/vm');
const vm = new EdgeVM({ timeout: 1000 });
try {
  vm.run('while(true) {}');
} catch (e) {
  console.log(e.message); // 'Script execution timed out.'
}
