CRUD in React JS using Axios | Building an App using React CRUD

In this article, you will learn how to apply a basic CRUD operation in React JS.

What is CRUD

Crud stands for

Create
Read
Update
Delete

No application in the world can be made without using CRUD operation. Let’s say, you uploaded a picture on Facebook, well that is a Create operation. To see how many likes/comments you got, you refresh your feed and see your post is reflecting on your feeds . that is a Read Operation. Soon you realized your caption has a spelling mistake, so you edit and corrected it, that is noting but Update Operation. After a while, you removed the post because you thought life is more than social media 😜 , so you went ahead and deleted the post, that is Delete Operation.

Now that Mark Zuckerberg and you guys, both understood what is crud operation, let’s understand it more with a code.

About the application

We are going to build a simple application where user can

enter their name and email
view their name and email
edit and update their name and email
delete their name and email

We are going to build the above same application as shown in the image

Wach Video Instead

Let’s build now

Pre-requisite

Basic of HTML, CSS and Java Script
Familier with basics of ES6 feture
Basic of React JS like functional component ,props , states , React Router , useState() , useEffect() 

Note - Even you are not very sure of the above topic, you can read the article. I have tried to make it as simple as possible.

Tech stack, packages and other stuff used to build this application

REACT JS , AXIOS (NPM PACKAGE) , BOOTSTRAP , HTML, CSS.

Note - One more thing need to build the application is patience and curiosity(hope you guys have installed that already).

Let’s get the basic react project setup

npx create-react-app CrudProject

We would also need a few node packages for the project, so let’s install those dependencies now itself.

npm i axios
npm i react-router-dom

src/App.js

import "./App.css";


function App() {
  return (
    <div className="container">
      <h2>Welcome to CRUD operation</h2>
    </div>
  );
}

export default App;

Also I have just imported the CSS CDN of bootstrap 5 to make the application simple

public/index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <meta name="theme-color" content="#000000" />
//bootstrap 5 css CDN added
    <link
      href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.0-beta1/dist/css/bootstrap.min.css"
      rel="stylesheet"
      integrity="sha384-0evHe/X+R7YkIZDRvuzKMRqM+OrBnVFBL6DOitfPri4tjfHxaWutUpFmBp4vmVor"
      crossorigin="anonymous"
    />

    <meta
      name="description"
      content="Web site created using create-react-app"
    />
    <link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" />
    
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
    <title>React App</title>
  </head>
  <body>
    <noscript>You need to enable JavaScript to run this app.</noscript>
    <div id="root"></div>
  
  </body>
</html>

Now that your boilerplate is ready , let’s perform our operations

Also since we are understanding the CRUD operation from the frontend side, I have used mockAPI as a backend server, so make the tutorial point-to-point and beginner-friendly

Create.js (CREATE Operation)

import axios from "axios";
import React, { useState } from "react";
import { useNavigate } from "react-router";
import { Link } from "react-router-dom";

const Create = () => {
  const [name, setName] = useState("");
  const [email, setEmail] = useState("");
  const history = useNavigate();

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log("clciekd");
    axios
      .post("https://62a59821b9b74f766a3c09a4.mockapi.io/crud-youtube", {
        name: name,
        email: email,
      })
      .then(() => {
        history("/read");
      });
  };

  return (
    <>
      <div className="d-flex justify-content-between m-2">
        <h2>Create</h2>
        <Link to="/read">
          <button className="btn btn-primary">Show Data</button>
        </Link>
      </div>
      <form>
        <div className="mb-3">
          <label className="form-label">Name</label>
          <input
            type="text"
            className="form-control"
            onChange={(e) => setName(e.target.value)}
          />
        </div>

        <div className="mb-3">
          <label className="form-label">Email address</label>
          <input
            type="email"
            className="form-control"
            aria-describedby="emailHelp"
            onChange={(e) => setEmail(e.target.value)}
          />
        </div>

        <button
          type="submit"
          className="btn btn-primary"
          onClick={handleSubmit}
        >
          Submit
        </button>
      </form>
    </>
  );
};

export default Create;

Read.js (Read Operation & Delete Operation)

import React, { useState, useEffect } from "react";
import axios from "axios";
import { Link } from "react-router-dom";

const Read = () => {
  const [data, setData] = useState([]);
  const [tabledark, setTableDark] = useState("");

  function getData() {
    axios
      .get("https://62a59821b9b74f766a3c09a4.mockapi.io/crud-youtube")
      .then((res) => {
        setData(res.data);
      });
  }

  function handleDelete(id) {
    axios
      .delete(`https://62a59821b9b74f766a3c09a4.mockapi.io/crud-youtube/${id}`)
      .then(() => {
        getData();
      });
  }

  const setToLocalStorage = (id, name, email) => {
    localStorage.setItem("id", id);
    localStorage.setItem("name", name);
    localStorage.setItem("email", email);
  };

  useEffect(() => {
    getData();
  }, []);

  return (
    <>
      <div className="form-check form-switch">
        <input
          className="form-check-input"
          type="checkbox"
          onClick={() => {
            if (tabledark === "table-dark") setTableDark("");
            else setTableDark("table-dark");
          }}
        />
      </div>
      <div className="d-flex justify-content-between m-2">
        <h2>Read Operation</h2>

                          )

export default Read;

Update.js (Update Operation)

import axios from "axios";
import React, { useEffect, useState } from "react";

import { Link, useNavigate } from "react-router-dom";

const Update = () => {
  const [id, setId] = useState(0);
  const [name, setName] = useState("");
  const [email, setEmail] = useState("");

  const navigate = useNavigate();

  useEffect(() => {
    setId(localStorage.getItem("id"));
    setName(localStorage.getItem("name"));
    setEmail(localStorage.getItem("email"));
  }, []);

  const handleUpdate = (e) => {
    e.preventDefault();
    console.log("Id...", id);
    axios
      .put(`https://62a59821b9b74f766a3c09a4.mockapi.io/crud-youtube/${id}`, {
        name: name,
        email: email,
