Small Ionic PWA app with NestJS/MongoDB backend

Main features:

1. Registration and Login (JWT)
2. List of air quality measurements by user city (part of the user profile)
3. List of all air quality measurements by country/city (desc sort by air quality index)
4. PWA support
5. List infinite scroll

User flow

1. Create account (all fields are required - city will be used for filtering)
2. Login
3. Home page shows two tabs:
   • My list: This is the list of measurements filtered by city name from user profile (see step 1)
   • All: This is the list of all measurements grouped by country/city and sorted by index

Run instructions

Project supports docker and it can be started using docker-compose:

1. cd Src/
2. docker-compose build
3. First time start only db service and add initial data
   • docker-compose up air-quality-db
   • When the container is running we need to add our inital user:
     • Open container bash: docker container exec -it air-mongodb bash
     • Open mongo: mongo
     • Switch to db use air_quality
     • Add user: db.createUser({user: 'air_quality_api', pwd: YOUR_PASSWORD, roles: [{role: 'readWrite', db: 'air_quality'}]})
     • Exit the mongo shell and container bash
   • Restore DB dump (DB dump can be found under Src/db/dump folder):
     • mongorestore -h localhost:27017 __PATH_TO_PROJECT__/Src/db/dump/
   • This will create two collections:
     • air-quality-indexes with 15 countries + each country has 25 measurements (subdocuments)
     • users with default user that can be used for login (username: [email protected], pass: 1234aQ)
4. When the database is populated stop the container (Do not delete the container because no volume is configured)
5. Set ENV vars and run all services:sudo JWT_SECRET="" DB_USER="air_quality_api" DB_PASS="" docker-compose up -d :
   • Frontend http://localhost:8081 (Use pre-defined demo username: [email protected] and password: 1234aQ)
   • Backend http://localhost:3000
   • Both parts, frontend and backend, support configuration with ENV vars (provided with docker-compose - see above).
