Local development

To run the code for your challenge locally, you’ll need node installed. Our test runners use Node 18 (as of April 2024). The script for your challenge (like ./your_grep.sh) will automatically compile your code using node before executing it. It’ll look something like this:

#!/bin/sh

exec node app/main.js "$@"

File structure

The files for your solution are placed in the app/ directory.
app/main.js contains the main() function, which is what the test runner executes.

Adding more files

You can add more files and directories to app/. The test runner will include them when compiling your code. For example, if you add a file at app/foo.js, you could use it like so:

function foo() {
    console.log('Hello from foo!');
}

function bar() {
    console.log('Hello from bar!');
}

module.exports = { foo, bar };

const { foo, bar } = require('./foo');

function main() {
    foo();  // Uses the foo function from foo.js
    bar();  // Uses the bar function from foo.js
}

We use the CommonJS syntax for importing and exporting of modules.

Adding dependencies

You can add dependencies to your project using npm.

Instructions for adding depedencies will be documented soon.
