skypanther / pushtest.js
Created Apr 20, 2017
GCM push test script
View pushtest.js
/*
Instructions
1. In the same directory where this js file exists, run `npm install gcm` (to install the required node module)
2. Get your GCM/FCM API Key from the Google APIs Console and paste it in place of "YOUR_GCM_API_KEY" below
2. You'll need your device's push token. You can get this by logging the token when your GCM-enabled app calls
the "success" callback after registering for push services. Paste it in place of "YOUR DEVICE_PUSH_TOKEN" below.
3. Run this with `node pushtest.js`
4. After a moment, you should get the push notification on your device

You can’t perform that action at this time.
