Key feature of Eventure WebApp:

• It has a Microservice architecture
• It runs in a docker container which is maintained by Kubernetes and Skaffold
• Handles concurrency
• All microservices are hosted differently in the docker container, and it communicates with one another using the async communication technique (event-bus)
• If certain services go down, then too other services will be fully functional.
• Simple implemented search feature by their title

Why to use Microservices Architecture?

Let's take an example to understand it easily.

• Have you ever booked an Indian railway ticket? If yes, then you might have surely experienced that servers are sometimes hangy (gets hangs) and slow down very frequently.

• So, why is it happening? The main reason is the Single Monolithic Server can't handle that much traffic at a time and need to add more servers at that movement which is somehow hard.

• So, By keeping all these problems in mind. Eventure WebApp is created using microservices architecture which can be easily scaled using Kubernetes.

Tech Implemented:

• FrontEnd:
  • next.js
  • react
  • bootstrap
  • language used: javascript
• BackEnd:
  • Language used: typescript
  • mongoose
  • NATS streaming server as an event bus
  • Jest for testing
  • Redis server for performing jobs and stripe for performing payments

Installation Info (locally):

Requirement:

Docker, Kubernetes, and Skaffold should be installed and configured. (Also, required ingress-nginx installed for Windows and MacOS users and enabled in minikube for Ubuntu)

• Clone the project and install it locally by using

  git clone https://github.com/Ishan25j/Eventure-App.git

• Go to every services folder (i.e auth, client, event-srv, expiration, orders, payment) and install required package using

  npm install

• After installing the required packages, try running test in auth, event-srv, orders and payment service by going to each folder and running

  npm run test

• Check and verify that each test passes and if you are facing any issue than try reinstalling and also verify that all package are available.

Note: Common folder is the submodule which orginally shared the common source code between each services which has been published on npm websites. Nothing that much important if you delete that submodule.

• After testing and installing package make you you have ingress-nginx enable on your system. Now go to you host file

In Windows: C:\Windows\System32\Drivers\etc\hosts In Linux\MacOS: \etc\hosts Edit it at the bottom add 127.0.0.1 eventure.dev and save it

• If you are using minikube then run minikube ip And use that ip instead of 127.0.0.1 (i.e. minikube_ip eventure.dev)

So, this edit tries to run eventure.dev locally instead of finding it online via browser

Now after completing all the above steps and configuration, let's run the application.

Running it locally:

• Now, you need to create three Kubernetes secrets in order to run this. So just edit the three given commands values as per the requirement

• For JWT:

  kubectl create secret generic jwt-secret --from-literal=JWT_KEY=<'JWT key you want to keep for auth'>

• For stripe private key:

  kubectl create secret generic stripe-secret --from-literal=STRIPE_KEY=<'use private key given by stripe'>

• For stripe public key:

  kubectl create secret generic stripe-p-secret --from-literal=STRIPE_P_KEY=<'use public key given by stripe'>

• Now, just run

  skaffold dev

and it will start the application.

Future Updates:

• Adding the functionality of buying multiple tickets at a time.
• Adding socketIO for creating realtime communication system.
• Adding the functionality of adding a custom image and background for individual event by the organizer.
• Adding credit system. (just like in steam app, for buying and selling tickets as at present after selling the ticket the seller is getting nothing)
• Adding the various categories for the event
