This is a hackathon boilerplate for new Node.js applications created by Major League Hacking. It is for hackers looking to get started quickly on a new hackathon project using the Node.js environment.

This project requires the following tools:

  • Node.js - The JavaScript environment for server-side code.
  • NPM - A Node.js package manager used to install dependencies.
  • PostgreSQL - A relational database system.

To get started, install NPM and Postgres on your local computer if you don't have them already. A simple way for Mac OS X users to install Postgres is using Here is a Windows guide for installing PostgresSQL.

Getting Started

Step 1. Clone the code into a fresh folder

$ git clone
$ cd mlh-hackathon-nodejs-starter

Step 2. Install Dependencies.

Next, we need to install the project dependencies, which are listed in package.json.

$ npm install

Step 3: Create an app on GitHub

Head over to GitHub OAuth apps and create a new OAuth app. Name it what you like but you'll need to specify a callback URL, which should be something like:


The default port for our app is 5000, but you may need to update this if your setup uses a different port or if you're hosting your app somewhere besides your local machine.

Step 4: Update environment variables and run the Server.

Create a new file named .env by duplicating .env.sample. Update the new file with the GitHub credentials. It should look similar to this:

# .env file

You replace the GitHub credentials here and update the database URL. Learn more about the required Environment Variables here.

Now we're ready to start our server which is as simple as:

$ npm start

Open http://localhost:5000 to view it in your browser.

The app will automatically reload if you make changes to the code. You will see the build errors and warnings in the console.

What's Included?

  • Express - A minimal web framework for Node.js web applications
  • Sequelize - A promise-based ORM for Node.js that supports PostgreSQL, MySQL, and SQLite.
  • Bootstrap 4 - An open source design system for HTML, CSS, and JS.
  • Handlebars - A popular templating language for building layouts.
