Overview of React Table example CRUD with Web API

We will build a React Table Tutorial Application in that:

• Each Tutorial has id, title, description, published status.
• We can create, retrieve, update, delete Tutorials.
• List of Tutorials is shown in a Table using react-table 7
• There is a Search bar for finding Tutorials by title.

Here are screenshots of our React.js CRUD Application.

– Create a Tutorial:

– Retrieve all Tutorials with a data table:

– Click on Edit button to update an item:

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

For Form Validation, please visit:
React Form Validation with Hooks example

– Search Tutorials by title:

This React-Table App 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 App Diagram with Axios and Router

Let's see the React Application Diagram that we're gonna implement:

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

– TutorialsList gets and displays Tutorials in table using react-table v7.
– Tutorial has form for editing Tutorial's details based on :id.
– AddTutorial has form for submission new Tutorial.

– They call TutorialDataService functions which use axios to make HTTP requests and receive responses.

Technology

• React 16/17
• react-table 7.6.3
• react-router-dom 5.2.0
• axios 0.21.1
• bootstrap 4
• fontawesome-free 5

Project Structure

Now look at the project directory structure:

Let me explain it briefly.

– package.json contains 4 main modules: react, react-router-dom, axios & bootstrap.
– App is the container that has Router & navbar.
– There are 3 items using React Hooks: TutorialsList, Tutorial, AddTutorial.
– http-common.js initializes axios with HTTP base Url and headers.
– TutorialService has functions for sending HTTP requests to the Apis.
– .env configures port for this React Table CRUD App.

Setup React.js Project

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

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

---

public

src

components

AddTutorial.js

Tutorial.js

TutorialsList.js

services

TutorialService.js

App.css

App.js

index.js

package.json

---

Install Bootstrap, FontAwesome for React Table CRUD App

Run command: npm install bootstrap @fortawesome/fontawesome-free.

Open src/App.js and modify the code inside it as following-

          import React, { Component } from "react"; import "bootstrap/dist/css/bootstrap.min.css"; import "@fortawesome/fontawesome-free/css/all.css"; import "@fortawesome/fontawesome-free/js/all.js";  class App extends Component {   render() {     // ...   } }  export default App;                  

Add React Router to React Table CRUD 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 reportWebVitals from './reportWebVitals';  ReactDOM.render(   <BrowserRouter>     <App />   </BrowserRouter>,   document.getElementById("root") );  reportWebVitals();                  

Add Navbar to React Table CRUD App

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

          import React from "react"; import { Switch, Route, Link } from "react-router-dom"; ...  import AddTutorial from "./components/AddTutorial"; import Tutorial from "./components/Tutorial"; import TutorialsList from "./components/TutorialsList";  function App() {   return (     <div>       <nav className="navbar navbar-expand navbar-dark bg-dark">         <a href="/tutorials" className="navbar-brand">           bezKoder         </a>         <div className="navbar-nav mr-auto">           <li className="nav-item">             <Link to={"/tutorials"} className="nav-link">               Tutorials             </Link>           </li>           <li className="nav-item">             <Link to={"/add"} className="nav-link">               Add             </Link>           </li>         </div>       </nav>        <div className="container mt-3">         <Switch>           <Route exact path={["/", "/tutorials"]} component={TutorialsList} />           <Route exact path="/add" component={AddTutorial} />           <Route path="/tutorials/:id" component={Tutorial} />         </Switch>       </div>     </div>   ); }  export default App;                  

You can simplify import statement with:
Absolute Import in React

Initialize Axios for sending HTTP requests

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.

Create Data Service

In this step, we're gonna create a service that uses axios object above to send HTTP requests.
The service exports CRUD functions and finder method:

• CREATE: create
• RETRIEVE: getAll, get
• UPDATE: update
• DELETE: remove, removeAll
• FINDER: findByTitle

services/TutorialService.js

          import http from "../http-common";  const getAll = () => {   return http.get("/tutorials"); };  const get = (id) => {   return http.get(`/tutorials/${id}`); };  const create = (data) => {   return http.post("/tutorials", data); };  const update = (id, data) => {   return http.put(`/tutorials/${id}`, data); };  const remove = (id) => {   return http.delete(`/tutorials/${id}`); };  const removeAll = () => {   return http.delete(`/tutorials`); };  const findByTitle = (title) => {   return http.get(`/tutorials?title=${title}`); };  const TutorialService = {   getAll,   get,   create,   update,   remove,   removeAll,   findByTitle, };  export default TutorialService;                  

We call axios (imported as http) 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 Object

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

components/AddTutorial.js

          import React, { useState } from "react"; import TutorialDataService from "../services/TutorialService";  const AddTutorial = () => {   const initialTutorialState = {     id: null,     title: "",     description: "",     published: false   };   const [tutorial, setTutorial] = useState(initialTutorialState);   const [submitted, setSubmitted] = useState(false);    const handleInputChange = event => {     const { name, value } = event.target;     setTutorial({ ...tutorial, [name]: value });   };    const saveTutorial = () => {     var data = {       title: tutorial.title,       description: tutorial.description     };      TutorialDataService.create(data)       .then(response => {         setTutorial({           id: response.data.id,           title: response.data.title,           description: response.data.description,           published: response.data.published         });         setSubmitted(true);         console.log(response.data);       })       .catch(e => {         console.log(e);       });   };    const newTutorial = () => {     setTutorial(initialTutorialState);     setSubmitted(false);   };    return (     // ...   ); };  export default AddTutorial;                  

First, we define and set initial state: tutorial & submitted.

Next, we create handleInputChange() function to track the values of the input and set that state for changes. We also have a function to get tutorial state and send the POST request to the Web API. It calls TutorialDataService.create() method.

For return, we check the submitted state, if it is true, we show Add button for creating new Tutorial again. Otherwise, a Form with Submit button will display.

          const AddTutorial = () => {   ...    return (     <div className="submit-form">       {submitted ? (         <div>           <h4>You submitted successfully!</h4>           <button className="btn btn-success" onClick={newTutorial}>             Add           </button>         </div>       ) : (         <div>           <div className="form-group">             <label htmlFor="title">Title</label>             <input               type="text"               className="form-control"               id="title"               required               value={tutorial.title}               onChange={handleInputChange}               name="title"             />           </div>            <div className="form-group">             <label htmlFor="description">Description</label>             <input               type="text"               className="form-control"               id="description"               required               value={tutorial.description}               onChange={handleInputChange}               name="description"             />           </div>            <button onClick={saveTutorial} className="btn btn-success">             Submit           </button>         </div>       )}     </div>   ); };  export default AddTutorial;                  

React Table for List of Objects Page

There will be:

• a search bar for finding Tutorials by title.
• a tutorials array displayed as a table.
• two buttons for edit & remove actions shown on the right of each row.

So we will have following state:

• searchTitle
• tutorials

We also need to use 4 TutorialDataService methods:

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

We're gonna use the Effect Hook: useEffect() to fetch the data from the Web API. This Hook tells React that the component needs to do something after render or performing the DOM updates. In this effect, we perform data fetching from API.

components/TutorialsList.js

          import React, { useState, useEffect, useMemo, useRef } from "react"; import TutorialDataService from "../services/TutorialService"; ...  const TutorialsList = (props) => {   const [tutorials, setTutorials] = useState([]);   const [searchTitle, setSearchTitle] = useState("");   const tutorialsRef = useRef();    tutorialsRef.current = tutorials;    useEffect(() => {     retrieveTutorials();   }, []);    const onChangeSearchTitle = (e) => {     const searchTitle = e.target.value;     setSearchTitle(searchTitle);   };    const retrieveTutorials = () => {     TutorialDataService.getAll()       .then((response) => {         setTutorials(response.data);       })       .catch((e) => {         console.log(e);       });   };    const refreshList = () => {     retrieveTutorials();   };    const removeAllTutorials = () => {     TutorialDataService.removeAll()       .then((response) => {         console.log(response.data);         refreshList();       })       .catch((e) => {         console.log(e);       });   };    const findByTitle = () => {     TutorialDataService.findByTitle(searchTitle)       .then((response) => {         setTutorials(response.data);       })       .catch((e) => {         console.log(e);       });   };    const openTutorial = (rowIndex) => {     const id = tutorialsRef.current[rowIndex].id;      props.history.push("/tutorials/" + id);   };    const deleteTutorial = (rowIndex) => {     const id = tutorialsRef.current[rowIndex].id;      TutorialDataService.remove(id)       .then((response) => {         props.history.push("/tutorials");          let newTutorials = [...tutorialsRef.current];         newTutorials.splice(rowIndex, 1);          setTutorials(newTutorials);       })       .catch((e) => {         console.log(e);       });   };    return (     ...   ); };  export default TutorialsList;                  

Let's continue to implement the UI.

This is where we use react-table for displaying tabular data. In addition to tutorial's fields (title, description, status), we also have Actions column with edit & delete icon buttons.

Install react-table with command: npm install react-table.

Similar to any table, a React Table includes columns and data:

• columns: array of columns which act as header groups. The columns can be recursively nested as much as needed.
• data: array of rows to be displayed on the table.

          const columns = [   {     Header: "Title",     accessor: "title",   },   {     Header: "Description",     accessor: "description",   },   ... ];  const data = [   {     title: "bezkoder Tut#1",     description: "description Tut#1",   },   {     title: "bezkoder Tut#2",     description: "description Tut#2",   },   ... ];                  

Now, how to modify the value of the cell, for example:

• if cell value is true/false, change it to 'Published'/'Pending'
• set a custom html element with icons and button click events

react-table supports the way to work with Cell property like this:

          const columns = [   ...,   {     Header: "Status",     accessor: "published",     Cell: (props) => {       return props.value ? "Published" : "Pending";     },   },   {     Header: "Actions",     accessor: "actions",     Cell: (props) => {       const rowIdx = props.row.id;       return (         <div>           <span onClick={() => openTutorial(rowIdx)}>             <i className="far fa-edit action mr-2"></i>           </span>            <span onClick={() => deleteTutorial(rowIdx)}>             <i className="fas fa-trash action"></i>           </span>         </div>       );     },   } ];  const data = [   {     title: "bezkoder Tut#1",     description: "description Tut#1",     published: true   },   {     title: "bezkoder Tut#2",     description: "description Tut#2",     published: false   },   ... ];                  

If you click on edit icon button of any Tutorial, the app will call openTutorial() method and direct you to Tutorial page. Similar for trash icon button, deleteTutorial() will be invoked.

Now we're gonna use a custom hook that react-table provides – useTable() – which implements many features: row sorting, filtering, searching, pagination, row selection, infinity scrolling…

          const {   getTableProps,   getTableBodyProps,   headerGroups,   rows,   prepareRow, } = useTable({   columns,   data: tutorials, });                  

useTable() takes columns and data to build a table instance.

We use several props from the instance:

• getTableProps() function is called inside the table tags to resolve any props needed by the table wrapper which built-in props is {role: "table"}.
• getTableBodyProps() function is called inside the tbody tags resolves any props needed by the table body wrapper which built-in props is {role: "rowgroup"}.
• prepareRow() function must be called on any rows to be displayed. It is responsible for lazily preparing a row for rendering.
• headerGroups and rows are internal data structures derived from columns and data above.

This is full code for building the UI and table:

          ... import { useTable } from "react-table";    ...   const columns = useMemo(     () => [       {         Header: "Title",         accessor: "title",       },       {         Header: "Description",         accessor: "description",       },       {         Header: "Status",         accessor: "published",         Cell: (props) => {           return props.value ? "Published" : "Pending";         },       },       {         Header: "Actions",         accessor: "actions",         Cell: (props) => {           const rowIdx = props.row.id;           return (             <div>               <span onClick={() => openTutorial(rowIdx)}>                 <i className="far fa-edit action mr-2"></i>               </span>                <span onClick={() => deleteTutorial(rowIdx)}>                 <i className="fas fa-trash action"></i>               </span>             </div>           );         },       },     ],     []   );    const {     getTableProps,     getTableBodyProps,     headerGroups,     rows,     prepareRow,   } = useTable({     columns,     data: tutorials,   });    return (     <div className="list row">       <div className="col-md-8">         <div className="input-group mb-3">           <input             type="text"             className="form-control"             placeholder="Search by title"             value={searchTitle}             onChange={onChangeSearchTitle}           />           <div className="input-group-append">             <button               className="btn btn-outline-secondary"               type="button"               onClick={findByTitle}             >               Search             </button>           </div>         </div>       </div>       <div className="col-md-12 list">         <table           className="table table-striped table-bordered"           {...getTableProps()}         >           <thead>             {headerGroups.map((headerGroup) => (               <tr {...headerGroup.getHeaderGroupProps()}>                 {headerGroup.headers.map((column) => (                   <th {...column.getHeaderProps()}>                     {column.render("Header")}                   </th>                 ))}               </tr>             ))}           </thead>           <tbody {...getTableBodyProps()}>             {rows.map((row, i) => {               prepareRow(row);               return (                 <tr {...row.getRowProps()}>                   {row.cells.map((cell) => {                     return (                       <td {...cell.getCellProps()}>{cell.render("Cell")}</td>                     );                   })}                 </tr>               );             })}           </tbody>         </table>       </div>        <div className="col-md-8">         <button className="btn btn-sm btn-danger" onClick={removeAllTutorials}>           Remove All         </button>       </div>     </div>   ); };  export default TutorialsList;                  

Object details Component

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

• get()
• update()
• remove()

We also use the Effect Hook useEffect() to get Tutorial by id in the URL.

components/Tutorial.js

          import React, { useState, useEffect } from "react"; import TutorialDataService from "../services/TutorialService";  const Tutorial = props => {   const initialTutorialState = {     id: null,     title: "",     description: "",     published: false   };   const [currentTutorial, setCurrentTutorial] = useState(initialTutorialState);   const [message, setMessage] = useState("");    const getTutorial = id => {     TutorialDataService.get(id)       .then(response => {         setCurrentTutorial(response.data);         console.log(response.data);       })       .catch(e => {         console.log(e);       });   };    useEffect(() => {     getTutorial(props.match.params.id);   }, [props.match.params.id]);    const handleInputChange = event => {     const { name, value } = event.target;     setCurrentTutorial({ ...currentTutorial, [name]: value });   };    const updatePublished = status => {     var data = {       id: currentTutorial.id,       title: currentTutorial.title,       description: currentTutorial.description,       published: status     };      TutorialDataService.update(currentTutorial.id, data)       .then(response => {         setCurrentTutorial({ ...currentTutorial, published: status });         console.log(response.data);         setMessage("The status was updated successfully!");       })       .catch(e => {         console.log(e);       });   };    const updateTutorial = () => {     TutorialDataService.update(currentTutorial.id, currentTutorial)       .then(response => {         console.log(response.data);         setMessage("The tutorial was updated successfully!");       })       .catch(e => {         console.log(e);       });   };    const deleteTutorial = () => {     TutorialDataService.remove(currentTutorial.id)       .then(response => {         console.log(response.data);         props.history.push("/tutorials");       })       .catch(e => {         console.log(e);       });   };    return (     ...   ); };  export default Tutorial;                  

And this is the code inside return:

          const Tutorial = props => {   ...    return (     <div>       {currentTutorial ? (         <div className="edit-form">           <h4>Tutorial</h4>           <form>             <div className="form-group">               <label htmlFor="title">Title</label>               <input                 type="text"                 className="form-control"                 id="title"                 name="title"                 value={currentTutorial.title}                 onChange={handleInputChange}               />             </div>             <div className="form-group">               <label htmlFor="description">Description</label>               <input                 type="text"                 className="form-control"                 id="description"                 name="description"                 value={currentTutorial.description}                 onChange={handleInputChange}               />             </div>              <div className="form-group">               <label>                 <strong>Status:</strong>               </label>               {currentTutorial.published ? "Published" : "Pending"}             </div>           </form>            {currentTutorial.published ? (             <button               className="badge badge-primary mr-2"               onClick={() => updatePublished(false)}             >               UnPublish             </button>           ) : (             <button               className="badge badge-primary mr-2"               onClick={() => updatePublished(true)}             >               Publish             </button>           )}            <button className="badge badge-danger mr-2" onClick={deleteTutorial}>             Delete           </button>            <button             type="submit"             className="badge badge-success"             onClick={updateTutorial}           >             Update           </button>           <p>{message}</p>         </div>       ) : (         <div>           <br />           <p>Please click on a Tutorial...</p>         </div>       )}     </div>   ); };  export default Tutorial;                  

Add CSS style for React Components

Open src/App.css and write CSS code as following:

          .list .action {   cursor: pointer; }  .submit-form {   max-width: 300px;   margin: auto; }  .edit-form {   max-width: 300px;   margin: auto; }                  

Configure Port for React Table CRUD 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 Table CRUD 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 Table CRUD CRUD example successfully with react-table 7, Hooks, Axios & React Router. Now we can consume REST APIs, display data table, search and modify data in a clean way. I hope you apply it in your project at ease.

For larger data, you may need to make pagination:
