microservices app

Advertisement :)

• This is my "Superior Grade" (don't know how it's called in your country) project it's not professional or nothing similar, it's just my try to learn new tech and introduce my self into micro services. This project was made with me during an intership in a company so i didn't have much time to make this with all i wanted to do, so i will be updating it in my free time adding better error handling and Oauth2 support.
• Feel free to use copy or send me feedback!

Hope you like the project!

Project Structure

First of all the project is hosted in a Google Cloud Platform VM, running in ubuntu 18.04lts, and the PostgreSQL databases are running in a Google Cloud Platform Cloud SQL, the storage is hosted with Firebase Storage and the NoSQL database is hosted with Firebase Realtime Database.

The github project is configured for localhost, the kong server will run by defualt in localhost, all the other services will go in localhost.

service	host	port
kong	http://localhost	:8000
konga	http://localhost	:1337
auth	http://localhost	:3002
profile	http://localhost	:8100
chat	http://localhost	:5000
posts	http://localhost	:3000
notifications	http://localhost	:9000

If you want to use the Konga interface to configure Kong you can download it here.

📂Server

📂Kong

I use Kong for handling the routing (Kong uses Nginx) and the auth, you can also handle logging, trafic etc. For easy configuration i use Konga UI

📂Auth

This API is programmed using compojure framework (Clojure) it basically call's to kong for creating the Basic Auth of the user and sends other petition to the profiles API for creating a profile for that user.

📂Profile

This API is programmed using fastapi framework (Python) it hosts al the data of profiles without email and password and store it in a postgresql database.

📂Chat

This API is programmed using .net CORE 3 (C#) and it hosts all the chat data and store it in a Firebase realtime database.

📂Posts

This API is programmed in Go and it hosts all the posts data and store it in a postgresql database.

📂Notifications

This API is programmed in Scala with SLICK and PLAY it get's the notifications and sends it to the specified device.

Create a constants.clj file in the auth core package

(ns auth.constants
  (:gen-class))

(def server-path (str "YOUR SERVER URL"))

(def api-key (str "YOUR SERVER API - KEY"))
