About The Project

RBH Bank is a digital bank built using Node.js, MongoDB, and Express. This application implements a user-service, account-service, and transaction-service to provide a complete banking experience.

Here are some of the key features of the Web App:

Very user friendly User interface.
Very robust and fast apis.
Extremely safe and everything is secure.
Whole server is tested using different testcases and if found any bugs then it does not affects other features. Of course, there are still a lot of issues to be tackled and new features to be added and we are slowly but surely working on it.

Usage

The backend is created on Express. It has 3 features for now.

New Account creation.
Account Validation and other basic user services.
Transactional services (NEFT type of tranfer technique).

The transactional services includes normal banking transactions between users, Account balance, Account validation, New account creation etc.

Description

This API is for creating a simple banking application developed in Node JS and secured by JWT token.

It includes three independent services
1. User-Service
2. Account-Service
3. Transaction-Service
The User-Service takes care of handling user related information.
The Account-Service takes care of handling account related information.
The User-Service takes care of handling user related information.
The Transaction-Service takes care of handling transaction related information.
We will be adding the low level designs of this seperately very soon.

User Service

The user-service allows users to register with RBH Bank and provides a validate function for login. The service also includes several GET and UPDATE requests. During login, a JSON Web Token (JWT) is generated and used as a header for the account-service.

Account Service

The account-service allows users to create a new account and includes functions such as createnewaccount, getaccountdetailsbyusername, getaccountdetails, addpayee, getpayees, and transferamount. The addpayee function is used to add a beneficiary for making payments. The username is used as a foreign key in the user table and the JWT token is used for security.

Transaction Service

The transaction-service includes two functions: trans summary and log summary. Trans summary provides a transaction summary with remarks after the transaction.

Folder structuring

The main file for the server is at the root named by index.js. There you can find the express server. Then there are various folders. Each of them quite different from other and you can find the details of it in the documentation.

Controllers -> it included the router and the breakpoints of the rest apis.
lib -> it contains some of the functions which have been used again and again in various places.
.vercel -> it inclued the files necessary for the deployment.
logger -> it includes the logger (what should be logged in the console what should'nt).
Middlewares -> simple middleware for jwt setup.
models -> it contains the schemas for different tables of the database.
validator -> it includes the validator files which validates the schema coming from the client.
Dao -> It includes all the data access operations (the functions which are related to database manipulation).
