A Node.js library providing access to V8 isolates to create completely isolated JavaScript environments. It lets you run untrusted or sandboxed code free of the Node.js runtime's capabilities.
Use cases
- run untrusted javascript code safely in nodejs
- create sandboxed js execution environments
- run user-submitted scripts in isolation
- execute plugin code without access to node runtime
- run multiple isolated javascript environments in one process
When to choose
- you need strong isolation for executing untrusted JavaScript in Node.js
- you want per-tenant script execution with shared memory transfer controls
- you need a native V8 isolate API rather than child processes
When to avoid
- you need a pure-JavaScript solution without native compilation
- you want a project under active feature development (it is in maintenance mode)
- you are on an odd-numbered or unsupported Node.js version
