Technology stack

This repository is built on top of Express.js, React.js, MongoDB and venom library, however in the implementation detail, we will find other supporting technologies as well.

Client side

• React - A JavaScript library for building user interfaces
• Ant Design Pro - A design system for enterprise-level products. Create an efficient and enjoyable work experience
• Testing Library - React Testing Library
• Umi Request - HTTP client for the executing HTTP request from browser to server.

Server side

• Node.js - evented I/O for the backend
• Express.js - Fast, unopinionated, minimalist web framework for Node.js
• MongoDB - The application data platform for NoSQL databases
• Mongoose - mongoose
• Swagger - Swagger (Not done yet)
• Jest - JavaScript testing framework
• Super Test - Super test API testing framework
• venom-bot - Venom is the most complete javascript library for Whatsapp

Details frameworks and packages can be found in the package.json files in server and client directory.

Running the application

Visual Studio Code

Prerequisites

• Node.js : To run npm packages
• MongoDB : As a database for the application

Steps

• To run via vscode, we should run the server and client side projects separately, and also make sure mongodb is up and running.
• Create a .env file inside of the server directory. Add the below entries or change accordingly. You can follow the .env.sample file to see the format.

DB_HOST=localhost
DB_PORT=27017
DB_NAME=appdb
JWT_SECRET=secret
JWT_EXPIRES_IN=100
PORT=5000
IS_MONGODB_CLOUD_URL=false
MONGODB_CLOUD_URL=mongodb+srv:// <USER >: <PASSWORD >@cluster0.abcd.mongodb.net/myFirstDatabase?retryWrites=true
DEFAULT_PAGE_SIZE=10
SENDGRID_API_KEY=123
FRONTEND_URL=http://localhost:8000

Server commands

We assume we run the MongoDB in the docker container.

cd server
npm i
npm run db:up
npm start

Client commands

cd client-pro
nvm use --lts
yarn
yarn start

Data seeding

To seed the database, we need to run the following commands in the server directory.

npm run db:seed
npm run db:migrate

You should be able to see the username and password in the /server/setup/users.json file. You can change these as you see fit.

Permission management ui

I have introduced a permission management ui for the application. Sample image is given below.

Centralized log to Sentry.io

We can also send the logs to sentry.io. To use this feature, we need to add the dsn entry into client/src/env.config.js. Setup snippet is like below in index.js file

Sentry.init({
  dsn: Config.dsn,
  integrations: [new Integrations.BrowserTracing()],
  tracesSampleRate: 1.0,
});

~~Test server API~~ (NOT DONE YET)

~~To view the api, open your browser and visit http://localhost:5000/api-docs Ideally we should add all of the API endpoints into the swagger, but for the demo purpose, we only added Products API endpoint.
To test the APIs, we can reuse the postman collection. Open docs/rbac-mern-boilerplate.postman_collection.json into Postman and you should see the endpoints with appropriate payloads.~~

Scripts

Types of testing

In this repository, we have included both unit testing and integration testing. For now, the code coverage is very low, but we are working on it to make it more than 90% somewhere in the future

Client side

• We incorporated only unit tests in client side, and mock all the externals dependencies like localStorage and axios.

To run the tests, we can run npm run test command.

Server side

• Integration testing: We have integrated the Jest as the testing library, and we have added supertest and mongodb-memory-server packages to make the integration testing easier.
• Unit testing: We have used Jest to test the service layers and mock the external dependencies like MongoDB.

To run the tests, we can run npm run test command.
