Fengari is a complete Lua 5.3 virtual machine, parser, and base libraries ported from the Lua C library to JavaScript ES6, runnable in Node.js and the browser. It exposes the same C API as native Lua through a JS API, letting developers embed and execute Lua code in JavaScript environments.

Use cases

• run Lua scripts in the browser
• embed a Lua interpreter in a Node.js application
• execute user-provided Lua code safely in a web app
• port Lua programs to JavaScript environments
• build a web-based Lua playground or REPL
• script game or app logic in Lua from JavaScript

When to choose

• you need to run Lua code where only JavaScript is available (browser or Node)
• you want Lua 5.3 semantics without native compilation
• you're building tools that let users write Lua scripts in web apps

When to avoid

• you need maximum Lua execution performance (use native Lua or LuaJIT)
• you need Lua 5.4 features or newer semantics
• you only need to parse or lint Lua rather than execute it
