I'm trying to extract Data from Object (API) in React

Question

Im trying to display the the API data on the page from an Object.

I attempted to display the data from the CamperList variable inside the camperlist.js file, but I'm having trouble.

I am going to paste in the code from each file that I have used to retrieve the API.

Here is the code from the camperlist.js file:

 import React from 'react'; import CamperListItem from './camper_list_item.js' //This is where the data is being pulled from VVVV const CamperList = (props) => { console.log('these are the datas', props.campers); return ( <div> hello world </div> ); } export default CamperList

In this next file is where you will find the "CamperList" component being rendered.

This is the App.js file:

 import React, { Component } from 'react'; import logo from './logo.svg'; //import './App.css'; import axios from 'axios'; import CamperList from './camperlist' export default class App extends Component { constructor(props) { super(props); this.state = { recentCampers: [], allTimeCampers: [], currentView: 'recentCampers' } } componentWillMount() { let current = this; axios.all([this.fetchRecent(), this.fetchAllTime()]).then(axios.spread(function(recentCampers, allTimeCampers){ current.setState({ recentCampers, allTimeCampers}); })); } fetchRecent(){ return axios.get('https://fcctop100.herokuapp.com/api/fccusers/top/recent') } fetchAllTime(){ return axios.get('https://fcctop100.herokuapp.com/api/fccusers/top/alltime') } changeView(currentView){ this.setState({currentView}) } render() { return ( <div> <h2> viewing top {this.state.currentView} </h2> <button onClick={()=> this.changeView('recentCampers')} className="btn btn-primary"> Recent </button> <button onClick={() => this.changeView('allTimeCampers')} className="btn btn-primary"> All Time </button> <CamperList campers={this.state[this.state.currentView]}/> </div> ); } }

And this is the camper_list_item.js file:

 import React from 'react'; const CamperListItem = (props) => { return( <div> camper item </div> ); } export default CamperListItem 

Answer 1

Were you able to receive your request succesfully?

Because by looking at your code. It will only display hello world .

You should change you CamperList component something like this to display your request.

import React from 'react';

import CamperListItem from './camper_list_item.js'

//This is where the data is being pulled from VVVV
const CamperList = (props) => {

  return (
    <div>
      {props.campers.map(c => {
        return <div key={c.username}>{c.username}</div>
      }}
    </div>
  );
}

export default CamperList

You may return the CamperListItem component after looping through the campers prop in CamperList .

import React from 'react';

import CamperListItem from './camper_list_item.js'

const CamperList = (props) => {
  return (
    <div>
      {
        props.campers.map((camper, i) => {
          return <CamperListItem camper={camper} key={i} />
        }
      }
    </div>
  );
}

export default CamperList;

Here I have illustrated an example of using the props given to CamperListItem :

import React from 'react';

const CamperListItem = (props) => {
  return(
  <div>{props.camper.name}</div>
  );
}

export default CamperListItem
