Display data on the table - React.js

This is a simple question. How to display the data in the table from json file?

table.js

   componentDidMount() {
    
        fetch('/apps.json')
       .then(rsp => rsp.json())
        .then(data => data.map(item => {
            return console.log(item);
        }));
    }

      <tbody> 
     {/* { data.map(item => {
      return(
         <tr>
        <td>{item.id}</td>
        <td>{item.name}</td>
        <td>{item.dateCreated}</td>
       </tr>
      );
      })} */}
     </tbody>

// Set appsData state
componentDidMount() {
  fetch("/apps.json")
  .then((rsp) => rsp.json())
  .then((rsp) => {
    this.setState({
      appsData: rsp
    });
  });

// Map the data
{ this.state.appsData.map(item => {
  return(
      <tr key={item.id}>
         <td>{item.id}</td>
         <td>{item.name}</td>
         <td>{item.url}</td>
         <td>{item.devOpsUrl}</td>
         <td>{item.techStack}</td>
         <td>{item.dateCreated}</td>
     </tr>
  );
})}

If you're interested in hooks, you can use the useState and useEffect hooks.


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

const Apps = () => {
  const [data, setData] = useState([])

  useEffect(() => {
    fetch("/apps.json")
      .then((rsp) => rsp.json())
      .then((data) => setData(data))
  }, [])

  return (
  <div>
    <h4>Apps List</h4>
      <table border={1} cellPadding={5}>
        <thead>
          <tr>
            <th>ID</th>
            <th>Name</th>
            <th>URL</th>
            <th>DevOps URL</th>
            <th>Tech Stack</th>
            <th>Date Created</th>
          </tr>
        </thead>
        <tbody>
          { data.map(item => (
            <tr key={item.id}>
              <td>{item.id}</td>
              <td>{item.name}</td>
              <td>{item.url}</td>
              <td>{item.devOpsUrl}</td>
              <td>{item.techStack}</td>
              <td>{item.dateCreated}</td>
            </tr>
          ))}
        </tbody>
      </table>
    </div>
  );
}

export default Apps

After you have converted the response received from the server into JSON, you can then set the JSON formatted response in your state variable using the setState() method.

componentDidMount() {
    fetch("/apps.json")
    .then((rsp) => rsp.json())
    .then((rsp) => {
      this.setState({
        appsData: rsp
      });
    });
}

In your JSX code, you can uncomment the code you have written with a small change that you need to add a unique key prop to each item in your list. This helps React identify which elements have really changed so as to render them again.

{ data.map(item => {
    return(
        <tr key={item.id}>
           <td>{item.id}</td>
           <td>{item.name}</td>
           <td>{item.url}</td>
           <td>{item.devOpsUrl}</td>
           <td>{item.techStack}</td>
           <td>{item.dateCreated}</td>
       </tr>
    );
})}

You can work with react-data-table-component its very simple to use this is a simple :

    import React from 'react';
    import DataTable from 'react-data-table-component';
    
    
  
    const data= [{"id":1,"name":"Alphazap","url":"http://1und1.de","devOpsUrl":"https://webs.com/nunc/commodo/placerat/praesent/blandit/nam/nulla.jsp","techStack":"sit amet cursus id turpis integer aliquet massa id lobortis convallis tortor risus dapibus","dateCreated":"05.06.2020"}]

      const columns = [
      // your columns here 
      ];
    
      return (
        <>

          <DataTable
            title="my table"
            columns={columns}
            data={data}
          />
        </>
      );
    };
