First, install the latest versions of node and npm from nodejs.org.

Then, from a console, run:

git clone https://github.com/hpr/AlgoBeginner
cd AlgoBeginner
npm install
npm run seed
npm run start-dev

The webapp should now be accessible from http://localhost:8080/. To deploy to Heroku, sign up for a Heroku account and install its client, then run these commands at the top-level directory to set up an app:

heroku login
heroku create <app-name>
heroku addons:create heroku-postgresql:hobby-dev
npm run deploy
heroku run bash
(from the Heroku bash prompt) npm run seed

When you’re done, your project should be accessible from https://.herokuapp.com!

To test admin functionality on a live site, use admin user murphy with password 123.

To test regular user functionality on a live site, use user cody with password 123.

Compete for the fastest times across various user-generated challenges in JavaScript! AlgoBeginner uses the vm2 library to run and time code server-side in a sandbox. All routes are protected to prevent unauthorized access or cheating.

Due to caching, vm2 will typically run a piece of code faster the second time than the first -- so try to submit your code multiple times in a row to get a faster clocking!
