Overview of React Material UI examples

We will build a React Tutorial Application using Material UI in that:

  • Each Tutorial has id, title, description, published status.
  • We can create, retrieve, update, delete Tutorials.
  • There is a Search bar for finding Tutorials by title.

Here are screenshots of our React CRUD Application.

– Create an item:

react-material-ui-examples-crud-app-create

– Retrieve all items:

react-material-ui-examples-crud-app-retrieve-all

– Click on Edit button to update an item:

react-material-ui-examples-crud-app-retrieve-one

On this Page, you can:

  • change status to Published using Publish button
  • delete the item using Delete button
  • update the item details with Update button

– Search Tutorials by title:

react-material-ui-examples-crud-app-search

This React Material UI Client consumes the following Web API:

Methods Urls Actions
POST /api/tutorials create new Tutorial
GET /api/tutorials retrieve all Tutorials
GET /api/tutorials/:id retrieve a Tutorial by :id
PUT /api/tutorials/:id update a Tutorial by :id
DELETE /api/tutorials/:id delete a Tutorial by :id
DELETE /api/tutorials delete all Tutorials
GET /api/tutorials?title=[keyword] find all Tutorials which title contains keyword

React.js Material UI Component Diagram with Router & Axios

Now look at the React components that we’re gonna implement:

react-material-ui-examples-crud-components

– The App component is a container with React Router. It has AppBar that links to routes paths.

TutorialsList component gets and displays Tutorials.
Tutorial component has form for editing Tutorial’s details based on :id.
AddTutorial component has form for submission new Tutorial.

– These Components call TutorialDataService methods which use axios to make HTTP requests and receive responses.

Technology

  • React 16
  • react-router-dom 5.1.2
  • axios 0.19.2
  • Material UI 4

Project Structure

react-material-ui-examples-crud-project-structure

I’m gonna explain it briefly.

package.json contains 4 main modules: react, react-router-dom, axios & @material-ui/core.
App is the container that has Router & AppBar.
– There are 3 components: TutorialsList, Tutorial, AddTutorial.
http-common.js initializes axios with HTTP base Url and headers.
css-common.js exports object that contains common styles for using in many components.
TutorialDataService has methods for sending HTTP requests to the Apis.
.env configures port for this React CRUD App.

Setup React Material UI Project

Open cmd at the folder you want to save Project folder, run command:
npx create-react-app react-material-ui-crud

After the process is done. We create additional folders and files like the following tree:


public

src

components

add-tutorial.component.js

tutorial.component.js

tutorials-list.component.js

services

tutorial.service.js

App.css

App.js

index.js

package.json


Import Material UI to React App

Run command: npm install @material-ui/core
Or: yarn add @material-ui/core

Add React Router to React Material UI App

– Run the command: npm install react-router-dom.
– Open src/index.js and wrap App component by BrowserRouter object.

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";

import App from "./App";
import * as serviceWorker from "./serviceWorker";

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById("root")
);

serviceWorker.unregister();

Add Common CSS to React Material UI App

In src folder, add css-common.js file.
This javascript file export an object that includes className of many components, the key is the className and nested object is css attribute named in camel case:

export const styles = {
    appBar: {
        backgroundColor: "#343A40",
        height: "50px",
        '& .MuiToolbar-regular': {
            minHeight: "50px"
        }
    },
    name: {
        marginRight: "15px"
    },
    link: {
        textTransform: "unset",
        color: "#a5a5a5",
        margin: "0 20px",
        textDecoration: "unset"
    }

From now, everytime we want to use one of the styles above, just import the styles object, then use props.classes to access the style.

Don’t forget to call withStyles() with styles as input parameter to return a function (higher-order component).

...
import { styles } from "./css-common";

import { ..., withStyles } from '@material-ui/core';

class YourComponent extends Component {
  render() {
    const { classes } = this.props

    return (
      <div>
        <AppBar className={classes.appBar} position="static">
          <Toolbar>
            <Typography className={classes.name} variant="h6">
              bezKoder
            </Typography>
            <Link to={"/tutorials"} className={classes.link}>
              <Typography variant="body2">
                Tutorials
              </Typography>
            </Link>
          </Toolbar>
        </AppBar>

        ...
      </div>
    );
  }
}

export default withStyles(styles)(YourComponent);

Add AppBar to React Material UI App

Open src/App.js, this App component is the root container for our application, it will contain a AppBar, and also, a Switch object with several Route. Each Route points to a React Component.

import React, { Component } from "react";
import { Switch, Route, Link } from "react-router-dom";
import "./App.css";
import { styles } from "./css-common"

import AddTutorial from "./components/add-tutorial.component";
import Tutorial from "./components/tutorial.component";
import TutorialsList from "./components/tutorials-list.component";

import { AppBar, Toolbar, Typography, withStyles } from '@material-ui/core';

class App extends Component {
  render() {
    const { classes } = this.props

    return (
      <div>
        <AppBar className={classes.appBar} position="static">
          <Toolbar>
            <Typography className={classes.name} variant="h6">
              bezKoder
            </Typography>
            <Link to={"/tutorials"} className={classes.link}>
              <Typography variant="body2">
                Tutorials
              </Typography>
            </Link>
            <Link to={"/add"} className={classes.link}>
              <Typography variant="body2">
                Add
            </Typography>
            </Link>
          </Toolbar>
        </AppBar>

          <Switch>
            <Route exact path={["/", "/tutorials"]} component={TutorialsList} />
            <Route exact path="/add" component={AddTutorial} />
            <Route path="/tutorials/:id" component={Tutorial} />
          </Switch>
      </div>
    );
  }
}

export default withStyles(styles)(App);

Initialize Axios for React Material UI HTTP Client

Let’s install axios with command: npm install axios.
Under src folder, we create http-common.js file with following code:

import axios from "axios";

export default axios.create({
  baseURL: "http://localhost:8080/api",
  headers: {
    "Content-type": "application/json"
  }
});

You can change the baseURL that depends on REST APIs url that your Server configures.

For more details about ways to use Axios, please visit:
Axios request: Get/Post/Put/Delete example

Create Data Service

In this step, we’re gonna create a service that uses axios object above to send HTTP requests.

services/tutorial.service.js

import http from "../http-common";

class TutorialDataService {
  getAll() {
    return http.get("/tutorials");
  }

  get(id) {
    return http.get(`/tutorials/${id}`);
  }

  create(data) {
    return http.post("/tutorials", data);
  }

  update(id, data) {
    return http.put(`/tutorials/${id}`, data);
  }

  delete(id) {
    return http.delete(`/tutorials/${id}`);
  }

  deleteAll() {
    return http.delete(`/tutorials`);
  }

  findByTitle(title) {
    return http.get(`/tutorials?title=${title}`);
  }
}

export default new TutorialDataService();

We call axios get, post, put, delete method corresponding to HTTP Requests: GET, POST, PUT, DELETE to make CRUD Operations.

Create React Components

Now we’re gonna build 3 components corresponding to 3 Routes defined before.

Add item Component

This component has a Form to submit new Tutorial with 2 fields: title & description.

react-material-ui-examples-crud-app-create

components/add-tutorial.component.js

import React, { Component } from "react";
import TutorialDataService from "../services/tutorial.service";

import { TextField, Button, withStyles } from "@material-ui/core"
import { styles } from "../css-common"

class AddTutorial extends Component {
    constructor(props) {
        super(props);
        this.onChangeTitle = this.onChangeTitle.bind(this);
        this.onChangeDescription = this.onChangeDescription.bind(this);
        this.saveTutorial = this.saveTutorial.bind(this);
        this.newTutorial = this.newTutorial.bind(this);

        this.state = {
            id: null,
            title: "",
            description: "",
            published: false,

            submitted: false
        };
    }

    onChangeTitle(e) {
        this.setState({
            title: e.target.value
        });
    }

    onChangeDescription(e) {
        this.setState({
            description: e.target.value
        });
    }

    saveTutorial() {
        var data = {
            title: this.state.title,
            description: this.state.description
        };

        TutorialDataService.create(data)
            .then(response => {
                this.setState({
                    id: response.data.id,
                    title: response.data.title,
                    description: response.data.description,
                    published: response.data.published,

                    submitted: true
                });
                console.log(response.data);
            })
            .catch(e => {
                console.log(e);
            });
    }

    newTutorial() {
        this.setState({
            id: null,
            title: "",
            description: "",
            published: false,

            submitted: false
        });
    }

    render() {
        // ...
    }
}

export default withStyles(styles)(AddTutorial)

First, we define the constructor and set initial state, bind this to the different events.

Because there are 2 fields, so we create 2 functions to track the values of the input and set that state for changes. We also have a function to get value of the form (state) and send the POST request to the Web API. It calls TutorialDataService.create() method.

For render() method, we check the submitted state, if it is true, we show Add button for creating new Tutorial again. Otherwise, a Form will display.

class AddTutorial extends Component {
  // ...

   render() {
        const { classes } = this.props

        return (
            <React.Fragment>
                {this.state.submitted ? (
                    <div className={classes.form}>
                        <h4>You submitted successfully!
                        <Button
                            size="small"
                            color="primary"
                            variant="contained"
                            onClick={this.newTutorial}>
                            Add
                        </Button>
                    </div>
                ) : (
                        <div className={classes.form}>
                            <div className={classes.textField}>
                                <TextField
                                    label="Title"
                                    name="title"
                                    value={this.state.title}
                                    onChange={this.onChangeTitle}
                                    required
                                />
                            </div>

                            <div className={classes.textField}>
                                <TextField
                                    label="Description"
                                    name="description"
                                    value={this.state.description}
                                    onChange={this.onChangeDescription}
                                    required
                                />
                            </div>

                            <Button
                                size="small"
                                color="primary"
                                variant="contained"
                                onClick={this.saveTutorial}>
                                Submit
                            </Button>
                        </div>
                    )}
            </React.Fragment>
        );
    }
}

List of items Component

This component has:

  • a search bar for finding Tutorials by title.
  • a tutorials array displayed as a list on the left.
  • a selected Tutorial which is shown on the right.

react-material-ui-examples-crud-app-retrieve-all

So we will have following state:

  • searchTitle
  • tutorials
  • currentTutorial and currentIndex

We also need to use 3 TutorialDataService methods:

  • getAll()
  • deleteAll()
  • findByTitle()

components/tutorials-list.component.js

import React, { Component } from "react";
import TutorialDataService from "../services/tutorial.service";
import { Link } from "react-router-dom";

import { styles } from "../css-common"
import { TextField, Button, Grid, ListItem, withStyles } from "@material-ui/core";

class TutorialsList extends Component {
  constructor(props) {
    super(props);
    this.onChangeSearchTitle = this.onChangeSearchTitle.bind(this);
    this.retrieveTutorials = this.retrieveTutorials.bind(this);
    this.refreshList = this.refreshList.bind(this);
    this.setActiveTutorial = this.setActiveTutorial.bind(this);
    this.removeAllTutorials = this.removeAllTutorials.bind(this);
    this.searchTitle = this.searchTitle.bind(this);

    this.state = {
      tutorials: [],
      currentTutorial: null,
      currentIndex: -1,
      searchTitle: ""
    };
  }

  componentDidMount() {
    this.retrieveTutorials();
  }

  onChangeSearchTitle(e) {
    const searchTitle = e.target.value;

    this.setState({
      searchTitle: searchTitle
    });
  }

  retrieveTutorials() {
    TutorialDataService.getAll()
      .then(response => {
        this.setState({
          tutorials: response.data
        });
        console.log(response.data);
      })
      .catch(e => {
        console.log(e);
      });
  }

  refreshList() {
    this.retrieveTutorials();
    this.setState({
      currentTutorial: null,
      currentIndex: -1
    });
  }

  setActiveTutorial(tutorial, index) {
    this.setState({
      currentTutorial: tutorial,
      currentIndex: index
    });
  }

  removeAllTutorials() {
    TutorialDataService.deleteAll()
      .then(response => {
        console.log(response.data);
        this.refreshList();
      })
      .catch(e => {
        console.log(e);
      });
  }

  searchTitle() {
    TutorialDataService.findByTitle(this.state.searchTitle)
      .then(response => {
        this.setState({
          tutorials: response.data
        });
        console.log(response.data);
      })
      .catch(e => {
        console.log(e);
      });
  }

  render() {
    // ...
  }
}

export default withStyles(styles)(TutorialsList)

Let’s continue to implement render() method:

// ...
import { Link } from "react-router-dom";

class TutorialsList extends Component {
  // ...

  render() {
    const { classes } = this.props
    const { searchTitle, tutorials, currentTutorial, currentIndex } = this.state;

    return (
      <div className={classes.form}>
        <Grid container>
          <Grid className={classes.search} item md={12}>
            <TextField
              label="Search by title"
              value={searchTitle}
              onChange={this.onChangeSearchTitle}
            />
            <Button
              size="small"
              variant="outlined"
              className={classes.textField}
              onClick={this.searchTitle}>
              Search
            </Button>
          </Grid>
          <Grid item md={4}>
            <h2>Tutorials List

            <div className="list-group">
              {tutorials &&
                tutorials.map((tutorial, index) => (

                    selected={index === currentIndex}
                    onClick={() => this.setActiveTutorial(tutorial, index)}

                    button	
                    key={index}>
                    {tutorial.title}
                  </ListItem>
                ))}
            </div>

            <Button

          </Button>
          </Grid>
          <Grid item md={8}>
            {currentTutorial ? (
              <div className={classes.tutorial}>
                <h4>Tutorial

                >
                  Edit
              </Link>
              </div>
            ) : (
                <div>
                  <br />
                  <p className={classes.tutorial}>Please click on a Tutorial...

</div> )} </Grid> </Grid> </div> ); } } export default withStyles(styles)(TutorialsList)

If you click on Edit button of any Tutorial, the app will direct you to Tutorial page.
We use React Router Link for accessing that page with url: /tutorials/:id.

You can add Pagination to this Component, just follow instruction in the post:
React Pagination with API using Material-UI

Item details Component

We’re gonna use the component lifecycle method: componentDidMount() to fetch the data from the Web API.

react-material-ui-examples-crud-app-retrieve-one

For getting data & update, delete the Tutorial, this component will use 3 TutorialDataService methods:

  • get()
  • update()
  • delete()

components/tutorial.component.js

import React, { Component } from "react";
import TutorialDataService from "../services/tutorial.service";

import { styles } from "../css-common"
import { TextField, Button, withStyles } from "@material-ui/core";

class Tutorial extends Component {
    constructor(props) {
        super(props);
        this.onChangeTitle = this.onChangeTitle.bind(this);
        this.onChangeDescription = this.onChangeDescription.bind(this);
        this.getTutorial = this.getTutorial.bind(this);
        this.updatePublished = this.updatePublished.bind(this);
        this.updateTutorial = this.updateTutorial.bind(this);
        this.deleteTutorial = this.deleteTutorial.bind(this);

        this.state = {
            currentTutorial: {
                id: null,
                title: "",
                description: "",
                published: false
            },
            message: ""
        };
    }

    componentDidMount() {
        this.getTutorial(this.props.match.params.id);
    }

    onChangeTitle(e) {
        const title = e.target.value;

        this.setState(function (prevState) {
            return {
                currentTutorial: {
                    ...prevState.currentTutorial,
                    title: title
                }
            };
        });
    }

    onChangeDescription(e) {
        const description = e.target.value;

        this.setState(prevState => ({

    }

    getTutorial(id) {
        TutorialDataService.get(id)
            .then(response => {
                this.setState({
                    currentTutorial: response.data
                });
                console.log(response.data);
            })
            .catch(e => {
                console.log(e);
            });
    }

    updatePublished(status) {
        var data = {
            id: this.state.currentTutorial.id,
            title: this.state.currentTutorial.title,
            description: this.state.currentTutorial.description,
            published: status
        };

        TutorialDataService.update(this.state.currentTutorial.id, data)
            .then(response => {
                this.setState(prevState => ({
                    currentTutorial: {
                        ...prevState.currentTutorial,
                        published: status
                    }
                }));
                console.log(response.data);
            })
            .catch(e => {
                console.log(e);
            });

            this.state.currentTutorial

                this.setState({

                });

    deleteTutorial() {

            .then(response => {
                console.log(response.data);
                this.props.history.push('/tutorials')
            })
            .catch(e => {
                console.log(e);
            });
    }

    render() {
       // ...
    }
}

export default withStyles(styles)(Tutorial)

Configure Port for React Material UI Client with Web API

Because most of HTTP Server use CORS configuration that accepts resource sharing retrictted to some sites or ports, so we also need to configure port for our App.

In project folder, create .env file with following content:

PORT=8081

Now we’ve set our app running at port 8081.

Run React Material UI examples App

You can run our App with command: npm start.
If the process is successful, open Browser with Url: http://localhost:8081/ and check it.

This React Client will work well with following back-end Rest APIs:
Express, Sequelize & MySQL
Express, Sequelize & PostgreSQL
Express, Sequelize & SQL Server
Express & MongoDb
Spring Boot & MySQL
Spring Boot & PostgreSQL
Spring Boot & MongoDB
Spring Boot & SQL Server
Spring Boot & H2
Spring Boot & Cassandra
Spring Boot & Oracle
Python/Django & MySQL
Python/Django & PostgreSQL
Python/Django & MongoDB

Conclusion

Today we’ve built a React CRUD Application successfully using Material UI with React Router & Axios. Now we can consume REST APIs, display, search and modify data in a clean way. I hope you apply it in your project at ease.

You can add Pagination Component with this tutorial:
