Lua Runner

A node module that runs Lua code with the power of webassembly!

About

Run your Lua code right inside of JavaScript or TypeScript with this module. Made from wasm_lua

• Lua 5.4.0

• 0 dependencies
• Tests
• Browser support

Installation

To install do

npm i lua-runner --save

Usage

To use the module

// import the package
import {run_lua} from "lua-runner"
// define the lua code
let testLuaCode = `    
function hello_lua()
    print("Hello World!")
    return "A"
end
return hello_lua()
`
// run the code with the run_lua function and use then to catch the response
run_lua(testLuaCode).then(res=> {
    console.log(res)
})

or without ES6 syntax as

let { run_lua } = require("lua-runner");
let testLuaCode = `    
function hello_lua()
    print("Hello World!")
    return "A"
end
return hello_lua()
`;
run_lua(testLuaCode).then(function (res) {
    console.log(res);
});

lua runner also has a function that returns a response object in the form of the following

interface response {
    return?: string
    exit_code?: string
}

This function call is run_lua_res instead of run_lua

let { run_lua_res } = require("lua-runner");
let testLuaCode = `    
function hello_lua()
    print("Hello World!")
    return "A"
end
return hello_lua()
`;
run_lua_res(testLuaCode).then(function (res) {
    console.log(res);
});
