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:

​

Adding dependencies

You can add dependencies to your project using npm.
