How to build

To build this, you have to worry about backend/ and frontend/ folders only, the files outside are mainly concerned with deployment on azure. I've also created a staging database which you can use while development.

Credentials are open, please don't misuse (it has incomplete data):

username = test

password = 0XP0V69Lvhwu9wbo

Backend

Inside backend/ folder

In src/index.ts: Change the mongoose.connect line to: (keep this change locally only)

mongoose.connect(`mongodb+srv://${db.user}:${db.pass}@cluster0.robkk.mongodb.net/test?retryWrites=true&w=majority`);

Then to build and run:

$ npm install
$ DB_USER=test DB_PASS=0XP0V69Lvhwu9wbo npm run dev

Frontend

Inside frontend/ folder

To build and run:

$ npm install
$ npm start
