Code engine (Context)

[TechStudent10]

The Context Engine must be completed in order for scripting to work.

The way the Context Engine is supposed to work is that it will

• Get the main.js script
• Limit its accessibility to scope

The app also needs a Context class that will help the user

• Add intractability to their applications
• Get information about elements (see Elements #5)
• Send/receive information from another server

For future reference:

Node.JS has a built-in vm module that allows you execute JavaScript in a sandboxed or contextified environment: https://nodejs.org/api/vm.html#vm-executing-javascript

Example (from the Node.JS docs):

const vm = require('node:vm');

const x = 1;

const context = { x: 2 };
vm.createContext(context); // Contextify the object.

const code = 'x += 40; var y = 17;';
// `x` and `y` are global variables in the context.
// Initially, x has the value 2 because that is the value of context.x.
vm.runInContext(code, context);

console.log(context.x); // 42
console.log(context.y); // 17

console.log(x); // 1; y is not defined.
