Reactjs Nodejs MongoDB CRUD Example – MERN Stack Application

Tutorial at: Reactjs Nodejs MongoDB CRUD Example

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.

List to do - Reactjs Nodejs MongoDB CRUD Example:

– I draw a fullstack overview Diagram Architecture from React.js Frontend to MongoDB database through Nodejs RestAPI backend.
– Develop Nodejs CRUD RestAPIs with the supporting of Mongoose ODM.
– 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 MongoDB database.

Overall Architecture System: Reactjs + Nodejs + MongoDB

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 Design Application

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 Application Design

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:
