Tutorial: “React Node.js MongoDB CRUD Example – MERN Stack Application”

In the tutorial, I introduce how to build an “React.js Nodejs CRUD MongoDB 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 MongoDB database using the supporting of Mongoose ODM.
– React.js project will consume the Nodejs CRUD RestAPIs by Ajax then show up on Reactjs component’s views.

Overall Architecture System: React Node.js MongoDB CRUD Example

React.js Nodejs MongoDB Diagram Architecture

We build a backend: Nodejs CRUD Application with MongoDB that provides RestAPIs for POST/GET/PUT/DELETE data entities and store them in MongoDB 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 MongoDB CRUD Example

In the tutorial “React Node.js MongoDB CRUD Example”, with Nodejs Backend, We have 4 main blocks for the application:

For building RestAPIs in Nodejs application, we use Express framework.
For interacting with database MongoDB, we use Mongoose ODM.
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 RestAPI Application Frontend Architecture Diagram

– 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.
