wordpress-firebase-auth-bridge v1.1.1

wordpress-firebase-auth-bridge

This is an API endpoint which is used by BRCS - Bot Remote Control System. It allows to authenticate users in Firebase with Wordpress details (using jwt). If user doesn't exist in Firebase it will be created first and then authenticated.

It works one-way-only so it creates and authenticates users from Wordpress in Firebase (doesn't work vice-versa yet).

In general what I wanted to achieve and what I actually achieved using this:

• I've made a Wordpress Woocommerce online shop and wanted users from mobile app to have exactly the same authentication database as users from online shop
• Users using online shop were authenticated by Wordpress database, but users using mobile app were authenticated by Wordpress first, then "copied" over to Firebase auth and then logged in to mobile app using Firebase SDK

You are thinking.. why not Wordpress only? Because I love Firebase features for mobile apps!

Features:

• fully customizable
• integrated with pm2 for auto-restarting, deployment and auto-scaling
• rate limiting & brute force protection (uses redis in production to maintain banned users)
• anti-ddos protection
• bot protection (throws 404 for bots and crawlers)
• integrated with cloudflare protection
• saves logs to file
• accept requests only from custom user agent (endpoint was used only by mobile app)
• well integrated with pmx monitor & new relic

Endpoints:

• status endpoint - /fb/status => GET
• auth endpoint - /fb/auth => POST => format: {"username":"test","password":"test"}

Requirements:

• WP REST API V2 enabled
• JWT Authentication for the WP REST API enabled

Setup:

I will be honest here. There may be some steps missing so you will have to figure it out yourself (I've stopped using it because mobile app which uses it is not developed anymore). 1. Install npm install --g babel-cli pm2 2. Clone repository 3. Run npm install 4. Modify settings in these files: - ./keys/server.crt && ./keys/server.key => generate your own keys - ./serviceAccountKey.json => get whole file from Firebase project - ./newrelic.js - ./ecosystem.config.js - ./dev_ecosystem.config.js - ./settings.js - ./package.json => modify name of your app (if changed) in pre-defined commands

Things to keep-in-mind:

• add your ssh key to deployment machine
• configure pm2 on your deployment machine (pm2 link)
• you could install some useful plugins for pmx monitor on deployment machine: (keep in mind that each of these has to be configured separately, also some of them are useless if you're not going to run Wordpress on same machine with Login API)
  • pm2 install pm2-server-monit
  • pm2 install pm2-php-fpm
  • pm2 install pm2-memcached
  • pm2 install pm2-mysql
  • pm2 install pm2-slack
  • pm2 install pm2-logrotate
• you have to open some ports (for example in AWS security group => 2096 for API and 43554 for pmx monitor in my case)
• if I recall correctly I had to exclude auth endpoint from cloudflare caching (somewhere on theirs website in domain settings)

Usage example:

• Run setup first: pm2 deploy ecosystem.config.js dev setup
• Then.. deploy!: pm2 deploy ecosystem.config.js prod
• And save process to be run on next startup: pm2 save

Useful commands:

You can do all these steps above with one command npm run pm2devcleandeploy or if you already did setup you can do npm run pm2devdeploy. You can also remotely destroy already running instances with: npm run pm2devdeploydestroy and read logs using npm run pm2devdeploylogs or clean them up with npm run pm2devdeploycleanup.
