Expo push notificaton server

A simple node.js server to store user credentials in a MongoDB database and send notifications to them via a Heroku scheduler command (/bin).

It is the server-side implementation of Expo push notifications in node.js for which Expo themselves provide an identical tool here, without the user saving part.

It is based on the pretty extensive hackathon-starter boilerplate where some of the scaffold comes from, but most of its features have been removed for simplification purposes.

Requirements

You'll need a running MongoDB instance for this to work. Otherwise, node won't know where to store the user data.

Setup

npm install

Usage

npm start

Tests

npm test

API calls

Save a new user:

POST /user/:type

Update a user's latest item ID:

PUT /user/:type

Delete a user:

DELETE /user/:type

• :type can be events or jobs
• Calls are x-www-form-urlencoded and contain one parameter:
  • token: Expo-generated push notification token

Sending push notifications to users

The command node bin/send-notifications.js is executed every full hour on Heroku using a scheduler
