eval-the-evil | Untrusted JavaScript snippet evaluator

eval-the-evil is a JavaScript library. eval-the-evil has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Eval the Evil safely evaluates untrusted JavaScript snippets, passing them JSON-compatible contexts, and returns JSON-compatible results:. It is intended for executing a large number of different, small (~10 lines), simple, synchronous scripts that describe business logic. It is not intended for running long-lived, persistent "apps" that require larger amounts of memory, NPM packages, make outbound connections, and so on. For that, maybe use CloudFlare Workers or AWS Lambda. Similarly, it is not meant for integrating tightly with your app. For that, you can use V8 bindings such as J2V8 (Java), isolated-vm (Node.js), V8js (PHP) and similar, or even V8 directly (C++).
