Buzz Words

Angular V16
Ionic V7
Docker
MongoDB
RedisDB - JSON
Redis - Pub/Sub
NestJS
Socket.IO - Websockets
REST - HTTP
JWT Auth - Access & Refresh Tokens
Signals
Monolithic - MVC

Prerequisite

Docker/Docker-Desktop node & npm MongoDB Compass - Optional Android Studio - Optional

Procedure to run this repo locally

1.) pull this repo
2.) cd to client and npm i
3.) cd to server and npm i
4.) cd back to root and docker-compose up server redis redis-insight mongodb --build -V
5.) cd to client again and npm run start:local
6.) check http://localhost:4200/
7.) to check redisdb http://localhost:8001/ (Host: redis, port: 6379, name: local, username: default, password: password) 8.) to check mongodb open mongodb compass and connect to this url mongodb://root:password123@localhost:27017/

Steps 4 & 5 can be skipped if you do this

From root cmd - "docker-compose up --build -V" this will also containerize the Angular-Ionic frontend app and also takes some time to containerize and run

Note

Angularv16, IonicV7, NestJS(monolithic), redis pub/sub & redisdb, MongoDB, Docker, built with only signals ( No NGRX & RxJS so far ), Basic default UI and themes, Socket.io extensive implementation
Make sure you use toggle device toolbar in your browser and set a android or ios device for better UI (Ionic)
Don't expect API & UI with error handling, loggers, testing and stuff (not there yet) , purely focusing on functionality
Default Profile Picture is a random 80 x 80 image from a website loaded at random, you can change it by adding your link for a image hosted online

What's special

Learning the Techs mentioned in note, as well as building a chat application project with backend scalability in mind

Possibilities

with redis pub/sub, websockets are H-scalable
and redis is also H-scalable with redis clusters
mongodb also H-scalable with multiple instances
NestJS monolithic to microservices (if required) is also possible with message brokers or other methods
