web_push_notifications

A demo project to send web based push notifications.

Please go through the article here to undestand how this demo project is implemented and how to generate the values needed for the required environmental variables.

Requirements

  • node >= 6
  • npm

Starting the app

You need to set the following environmental variables

VAPID_SUBJECT
VAPID_PUBLIC_KEY
VAPID_PRIVATE_KEY
AUTH_SECRET

Afterwards type

npm install

to install the dependencies and then

node index.js

to start the server. If you don't have any environmental variable named PORT set, the server should start on port 8080.

Testing the app

  1. Goto the URL http://localhost:8080 from either Chrome or Firefox, latest versions.
  2. Click the Subscribe to push notifications button, and choose to allow notifications when prompted by the browser.
  3. Use the following curl command to send a push notification, you will obviously need to change the auth-secret header value to match your environmental variable.
curl -G --header "auth-secret: qwertyuiop" "http://localhost:8080/notify/all" \
    --data-urlencode "title=Willy Wonka" \
    --data-urlencode "message=Willy Wonka's new chocklate is awesome" \
    --data-urlencode "clickTarget=http://www.favoritemedium.com"
