In the tutorial, I introduce how to build an “React.js Nodejs CRUD MySQL Example” project with the help of Ajax to POST/GET/PUT/DELETE requests with step by step coding examples:

– Nodejs project produces CRUD RestAPIs with MySQL database using the supporting of Sequelize ORM.
– React.js project will consume the Nodejs CRUD RestAPIs by Ajax then show up on Reactjs component’s views.

what will I do?

– I draw a fullstack overview Diagram Architecture from React.js Frontend to MySQL database through Nodejs RestAPI backend.
– Develop Nodejs CRUD RestAPIs with the supporting of Sequelize ORM.
– Implement Reactjs CRUD application with Ajax fetching APIs to do CRUD request (Post/Get/Put/Delete) to Nodejs Backend APIs.
– I create a testsuite with a number of integrative testcases with CRUD RestAPI requests from Reactjs to do CRUD requests to Nodejs RestAPIs Server and save/retrieve data to MySQL database.

Overall Architecture System: Reactjs + Nodejs + MySQL

• We build a backend: Nodejs CRUD Application with MySQL that provides RestAPIs for POST/GET/PUT/DELETE data entities and store them in MySQL database.
• We implement React.js CRUD Application that use Ajax to interact (call/receive requests) with Nodejs CRUD application and display corresponding data in Reactjs Component.

Nodejs MySQL CRUD Design Application

We have 4 main blocks for the application:

• For building RestAPIs in Nodejs application, we use Express framework.
• For interacting with database MySQL, we use Sequelize ORM.
• We define APIs URL in router.js file
• We implement how to process each API URL in controller.js file
• We use Bootstrap and JQuery Ajax to implement frontend client.

Reactjs CRUD Application Design

– Reactjs CRUD Application is designed with 2 main layers:

React.js components let you split the UI into independent, reusable pieces, and think about each piece in isolation.
Ajax is used by Reactjs component to fetch (post/put/get/delete) data from remote restapi by http request
Reactjs CRUD Application defines 5 components:

• Home.js is used serve as the landing page for your app.
• AppNavbar.js is used to establish a common UI feature between components.
• CustomerList.js is used to show all customers in the web-page
• CustomerEdit.js is used to modify the existed customer
• App.js uses React Router to navigate between components.

Integrative Project Goal

Reactjs Home page:

Reactjs List all data:

Reactjs add data:

Reactjs update data:

Reactjs delete a customer with id=2, check the Customer List after deleting:

Check MySQL Database after do CRUD operations:
