I built PushServer as a way to send push notifications for my new app Letters - a game about spelling words. Please check it out!
A nodejs server that runs on heroku for sending Apple APNS push notifications.
Uses mongodb to store device token information and subscribed channel lists.
- Provides API to update device tokens for the sandbox and production environments.
- Provides API to subscribe/unsubscribe devices to/from channels
- Provices web interface to send push notifications to channels (using Github auth for admin login)
Setup your app for Remote Push Notifications using the
docs
and download the Remote Push Notifications certificate .cer files
for Development and Production. Import them both into your keychain.
Open Keychain Access and export both the certificate and private key
(highlight them both) to a .p12 file. I recommend saving them as:
apns_dev_Certificates.p12
apns_prod_Certificates.p12
Then create the corresponding .pem files:
#dev
openssl pkcs12 -clcerts -nokeys -out apns_dev_cert.pem -in apns_dev_Certificates.p12
openssl pkcs12 -nocerts -out apns_dev_key.pem -in apns_dev_Certificates.p12
#prod
openssl pkcs12 -clcerts -nokeys -out apns_prod_cert.pem -in apns_prod_Certificates.p12
openssl pkcs12 -nocerts -out apns_prod_key.pem -in apns_prod_Certificates.p12
# optional to remove passphrase from keys
openssl rsa -in apns_dev_key.pem -out apns_dev_key.unencrypted.pem
openssl rsa -in apns_prod_key.pem -out apns_prod_key.unencrypted.pem
Copy the *.pem files into the certs folder of this repo.
Create two github apps, one for local development and one for production (you need two because the callback URL must be pre-registered and match the callback URL specified during the login flow). These apps are just used to authenticate the admin for the push dashboard and prevent anyone else from sending notifications from your server.
npm install -d
heroku apps:create <app_name_here>
heroku addons:add mongolab # free 240mg mongo tier
See config.js for the environment variables you need to set for
running the server. MONGOLAB_URI will be provided in your heroku
environment if you ran the above heroku addons command.
export SITENAME="My push server"
export SITEURL=http://localhost:5000
export ADMIN_USERID=<your github userid>
export GH_CONSUMER_KEY=<your github app Client ID>
export GH_CONSUMER_SECRET=<your github app Client Secret>
export GH_CALLBACK=http://localhost:5000/oauth/callback
export EXPRESS_SESSION_SECRET=<random string>
Run mongod in a terminal
cd /path/to/mongodb/bin
./mongod
Run PushServer using foreman (should start on port 5000)
foreman start
Create a production branch of this repo
git branch production
Remove *.pem from .gitignore and add your certs/*.pem files to
the branch - this way your certificates will be deployed to heroku.
heroku config:set GH_CONSUMER_KEY=<your github app Client ID> \
GH_CONSUMER_SECRET=<your github app Client Secret> \
GH_CALLBACK=http://yourdomain.example.com/oauth/callback \
ADMIN_USERID=<your github userid> \
EXPRESS_SESSION_SECRET=<random string> \
SITENAME="My push server" \
SITURL=http://yourdomain.example.com
Push to heroku to deploy
git push heroku production:master
NEVER commit your cert/pem files and push them to a public repo. Make sure to work in a private local branch using your certs/keys when you push to heroku.
POST /dev/updateDeviceToken
Create or update a device token entry in the database, optionally (un)subscribing it to some channels. The device token is marked in the database as a sandbox/development environment token.
Parameters
- deviceToken - 64 character string of the iOS device push token (required)
- channels - comma separated string of channels to subscribe to (optional)
- unsubscribe - string "true" if the channels should be unsubscribed instead (optional)
Returns 200 status code on success.
POST /prod/updateDeviceToken
Create or update a device token entry in the database, optionally (un)subscribing it to some channels. The device token is marked in the database as a production environment token.
Parameters
- deviceToken - 64 character string of the iOS device push token (required)
- channels - comma separated string of channels to subscribe to (optional)
- unsubscribe - string "true" if the channels should be unsubscribed instead (optional)
Returns 200 status code on success.
GET /channel_list/:device_token
Parameters
- :device_token - 64 character string of the iOS device push token (required)
Returns 200 status plain text comma separated list of channels the passed-in device token is currently subscribed to.
Returns 404 status if device token is not found.
Returns 500 status on other error.
Navigate to the website root, then click "login with github" in the upper right to authenticate as the admin. Once logged in, you will see the "dashboard" link in the nav bar.
On the dashboard page you can select the Dev or Prod environment, the channel to send a notification to, the badge number (use 0 to clear the badge), and the message to send in the notification payload.
Hit the "Submit" button, and if all goes well, you will see a "Success" message on the next page and a push notification arrive on your device! Errors are logged to the server console.
