What You Get
– React Native front-end (deployable to all web , iOS , android)
– Node.js back-end with PostgreSQL database
– React admin dashboard (Single-page application)
Why React Native?
Why Node js , express , postgres (PERN stack)?
We’ve chosen node and express as the back-end due to it’s powerful middleware design , allowing us to dissect and organise routes as well as add middleware (conditional too!) to have powerful functionality , as well as being minimal by design. Postgres is also a good choice for this application because of its performance and capabilities. Express is good because it allows us to combine our middleware , controllers , routers and reduce coding/development time significantly.
The front-end (client) is the main app , which can be exported to web , ios and/or android. Using Expo we can easily deploy either as a full-apk , or a bundled (and more efficient) apk to release on the store.
The whole client is a single-page (SPA) too , which means better performance , more user-friendliness and fluid pages. Users will be playing on the client , with their progress , attempts , levels saved
while they are actively engaged in the app. The client will load data from the backend and respond accordingly. We feature adverts for Google Admob , which can be configured in the admin dashboard , among other things. Easily enable/disable adverts , change advert providers , ID , etc.

—Superadmins are hardcoded in the backend and must be configured manually in the code , but it’s very easy and only requires changing the email (and setting it to whatever you wish the superadmin’s email to be) , and then create a new account in the front-end.
—Token-based authentication , with tokens being stored in the cookies (for dashboard login) and Secure Storage/Async Storage depending on your system. Mobile devices will use SecureStorage.
—JWT tokens are used , which are technically public but have a private key , incredible security.
—Token verification so if any tokens are tampered with they will not let you pass!
