Reactjs Nodejs PostgreSQL Example

reactjs nodejs postgresql

Link tutorial: https://loizenai.com/reactjs-nodejs-postgresql-example/

In the tutorial, I introduce how to build an “React.js Nodejs CRUD PostgreSQL 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 PostgreSQL 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.

List to do:

– I draw a fullstack overview Diagram Architecture from React.js Frontend to PostgreSQL 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 PostgreSQL database.

Overall Architecture System: Reactjs + Nodejs + PostgreSQL

![Overall Architecture System: Reactjs + Nodejs + PostgreSQL]https://loizenai.com/wp-content/uploads/2020/11/React.js-Nodejs-PostgreSQL-Diagram-Architecture.png

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

Nodejs PostgreSQL CRUD Design

We have 4 main blocks for the application:

  • For building RestAPIs in Nodejs application, we use Express framework.
  • For interacting with database PostgreSQL, 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 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.
