How to display json data in a reactjs component

Question

I'm new to react. I dont know how to import json data in one of my component.

This is my json data:

[
    {
        "id": 1,
        "firstname": "abc",
        "lastname": "xyz",
        "phone": "[phone]",
        "email": "[email protected]"
    },
    {
        "id": 2,
        "firstname": "def",
        "lastname": "uvz",
        "phone": "[phone]",
        "email": "[email protected]"
    }
]

Here is list Component :

<Container>
  <Grid>
    <Grid.Row>
      <Grid.Column>
        <Header>List</Header>
        <List>
          <List.Item block>
            <List.Content>FirstName and Last Name</List.Content>
            <List.Content>Phone</List.Content>
          </List.Item>
        </List>
      </Grid.Column>
    </Grid.Row>
  </Grid>
</Container>

Can anyone help me in displaying the list? Thanks in advance

You can import contacts from your data.json, and use the map() to iterate and display contacts.

import React, { Component } from "react";
import { Container, Grid, Header, List } from "semantic-ui-react";
import contacts from './data.json';

class App extends Component {

  render() {
    return (
      <Container>
        <Grid>
          <Grid.Row>
            <Grid.Column>
              <Header>List</Header>
              <List>
                {contacts.map(el => {
                  return (
                    <List.Item  key={el.id}>
                      <List.Content>
                        {el.firstname} {el.lastname}
                      </List.Content>
                      <List.Content>{el.phone}</List.Content>
                    </List.Item>
                  );
                })}
              </List>
            </Grid.Column>
          </Grid.Row>
        </Grid>
      </Container>
    );
  }
}

export default App;

But I think using Table component from semantic-ui-react would be a better for this.

import React, { Component } from "react";
import {  Table } from "semantic-ui-react";
import contacts from './data.json';

class App extends Component {

  render() {
    return (
      <Table singleLine>
        <Table.Header>
          <Table.Row>
            <Table.HeaderCell>Id</Table.HeaderCell>
            <Table.HeaderCell>Fullname</Table.HeaderCell>
            <Table.HeaderCell>Phone</Table.HeaderCell>
            <Table.HeaderCell>Email</Table.HeaderCell>
          </Table.Row>
        </Table.Header>

        <Table.Body>
          {contacts.map(el => {
            return (
              <Table.Row key={el.id}>
                <Table.Cell>{el.id}</Table.Cell>
                <Table.Cell>
                  {el.firstname} {el.lastname}
                </Table.Cell>
                <Table.Cell>{el.phone}</Table.Cell>
                <Table.Cell>{el.email}</Table.Cell>
              </Table.Row>
            );
          })}
        </Table.Body>
      </Table>
    );
  }
}

export default App;
