edge-push-server

This server sends push notifications to Edge client apps. It contains an HTTP server that clients can use to register for notifications, and a background process that checks for price changes and actually sends the messages.

The docs folder has can find an example of how to use the v2 API.

Setup

This server requires a working copies of Node.js, Yarn, PM2, and CouchDB. We also recommend using Caddy to terminate SSL connections.

Set up logging

Run these commands as a server admin:

mkdir /var/log/pm2
chown edgy /var/log/pm2
cp ./docs/logrotate /etc/logrotate.d/loginServer

Manage server using pm2

First, tell pm2 how to run the server script:

# install:
pm2 start pm2.json
pm2 save

# check status:
pm2 monit
tail -f /var/log/pushServer.log
tail -f /var/log/priceDaemon.log

# manage:
pm2 reload pm2.json
pm2 restart pm2.json
pm2 stop pm2.json

pm2 restart pushServer // Just the HTTP server
pm2 restart priceDaemon // Just the price checker

Updating

To update the code running on the production server, use the following procedure:

git pull
yarn
yarn prepare
pm2 restart pm2.json

Each deployment should come with its own version bump, changelog update, and git tag.
