In this tutorial, we’re gonna build a React CRUD (Create, Read, Update, Delete) Application with JWT Authentication, File upload/ download, and consume CRUD Restful APIs developed by Spring boot.
- JWT Authentication Flow for User Signup & User Login.
- Project Structure for React JWT Authentication (without Redux) with LocalStorage, React Router, Axios, react-bootstrap, react-hook-form.
- Creating React Components with Form Validation.
- Dynamic Navigation Bar in React App.
Let's start with creating a React App using create-react-app CLI.
To create a new app, you may choose one of the following methods:
Using npx
npx create-react-app react-appname
Using npm
npm init react-app react-appname
Install some npm packages:
npm install bootstrap reactstrap
npm install react-bootstrap bootstrap
npm install reactstrap react react-dom
npm install axios
npm install react-router-dom
npm install react-hook-form
