HapiJS Authentication Sample

This sample project demonstrates how to set up a user authentication API with Hapi.js using JSON Web Tokens. There are several endpoints exposed in the sample, including user login and signup, along with an example of a protected instructors resource.

Demo API

The API for the course is served at https://user-authentication-api.now.sh/api

Installation and Running the App

Clone the repo, then:

npm install
node server.js

The app will be served at localhost:3001.

Local Setup

To setup the API locally, you will need to run MongoDB or have an MLab instance. Create a .env file and populate it with the following values:

SECRET_KEY=<secret_key>
MLAB_USER=<mlab_user>
MLAB_PASSWORD=<secret_key>
MLAB_DOMAIN=<domain>
MLAB_DB=<database>

Available Routes

  • Used for logging a user in. Accepts user (where you can supply a users username or email) and password to authenticate a user. Returns a JWT.
