Getting Started

To install this application, run the following commands:

git clone https://github.com/NiteshReddi/Miracle_ECommerce_POC.git 
cd Miracle_ECommerce_POC

This will get a copy of the project installed locally. To configure all of its dependencies and start each app, follow the instructions below.

Configure Database

Now you can run the server from cmd with file path commad: mongod which runs mongoDB server.

Once MongoDB compass is installed you must create a document. You must configure in the file application.configure located in the path src/main/resources/.

In the file application.configure you must edit the parameters spring.data.mongodb.host=localhost and spring.data.mongodb.port=27017 and spring.data.mongodb.database=<MyDocumentName> with the values you defined.

Configure Vault:

Run command in cmd. Command: vault server --dev --dev-root-token-id="<MyVaultToken>"

This command starts vault server and generate a Root Token:"" & vault Api Address: http://127.0.0.1:8200 by default. You must configure in the Vault-Service module in file application.properties located in the path src/main/resources/.

Module Description

1. Client-Service: This module we have multiple Api's to interact with all the other services to create Order, Get order Details, Store user Credentials in vault and retrieve user Credentials from vault.

2. JWT-Service: This module is used to validate client user on server side. This module has two services, one to generate JWT Token for the client user and other to validate JWT token when accessing other service modules.

3. Vault-Service: This module is used to Store user credentials in Hashicorp vault and retrieve them when required.

4. Create-Order-Api-Service: This module is used to place orders with the appropriate order details. Once the Api is called, order is placed and order details are stored in DB.

5. Get-Order-Api-Service: This module is used to GET orderDetails. Once the Api is called, order details are retrieved from DB.

6. Update-Order-Api-Service: This module is used to Update orderDetails based on order_Id. Once the Api is called, order details are updated in DB based on given Order_Id.
