Python API Output is not getting formatted in ReactJS

Below is my ReactJS component written where I want to print the output as list of buttons.

// CityContent.js



import React, { Component } from "react";

import axios from "axios";



const pStyle = {

  backgroundColor: "#79D3EF",

  color: "white"

};



export default class CityContent extends Component {

  constructor(props) {

    super(props);



    this.state = {

      citydetail: 

    };

  }



  componentDidMount() {

    axios.get("http://127.0.0.1:8000/Delhi").then(res => {

      const citydetail = res.data;

      this.setState({ citydetail });

    });

  }



  render() {

    console.log(this.state);

    return (

      <div className="content-wrapper">

        <section className="content-header">

          <div className="row">

            <div className="col-md-4">

              <div className="box">

                <div className="box-body">

                  <div className="row">

                    <div className="col-md-8">

                      <ul>

                        {this.state.citydetail.map(city => (

                          <li>

                            {city.name}

                            <button>{city.name}</button>

                          </li>

                        ))}

                      </ul>

                    </div>

                  </div>

                </div>

              </div>

            </div>

          </div>

        </section>

      </div>

    );

  }

}

The Api used is written in python Boto which returns the list of instances whose code is as follows:

import boto3

import json



Cities = {'Delhi': 'LB1',

          'Hyderabad': 'LB2', 'Mumbai': 'LB3'}





def CityDetail(city):

    client = boto3.client('elb')

    response = client.describe_instance_health(

        LoadBalancerName=Cities[city]

    )

    Instances = dict()

    InstanceList = list()

    for goods in response['InstanceStates']:

        InstanceList.append({"name": goods['InstanceId']})

    print(InstanceList)

Api is returning output as :

   [{'name': 'i-cc608f4d'}, {'name': 'i-fd608f7c'}, {'name': 'i-fe608f7f'}]

I want these IDs to be printed as buttons one below other in ReactJS component.

In the current code when ran doesn't show anything on screen and returns this.state.citydetail.map is not a function on chrome console.

If data type is array on browser console (not python console) and no error on browser console, then check your CSS rules.

If data type is array on browser console (not python console) and no error on browser console, then check your CSS rules.

There's an error , on console it is showing: CityContent.jsx?a1a1:44 Uncaught (in promise) TypeError: this.state.citydetail.map is not a function

Looks like Python server is not responding with JSON - try this:

Instances = dict()

InstanceList = list()

for goods in response['InstanceStates']:

    InstanceList.append({"name": goods['InstanceId']})

json_str = json.dumps(InstanceList)

print(json_str)

CityContent.jsx?a1a1:44 Uncaught (in promise) TypeError: this.state.citydetail.map is not a function . I'm getting above error in ReactJS component

Making above change made my output like this: [{"name": "i-cc608f4d"}, {"name": "i-fd608f7c"}, {"name": "i-fe608f7f"}]

That suggests this.state.citydetail is not an array. My guess is that response from API is not of content-type json. What does network tab in chrome dev tools say ? Did you try code from my answer ? Please add a debug to your get method and check the console axios.get("http://127.0.0.1:8000/Delhi").then(res => { console.log('data', res.data); console.log('status', res.status); const citydetail = res.data; this.setState({ citydetail }); });

I've used your code, and I can see below snippet in chrome console logs : data {status: "[{"name": "i-cc608f4d"}, {"name": "i-fd608f7c"}, {"name": "i-fe608f7f"}]"} CityContent.jsx?a1a1:27

But still the " TypeError: this.state.citydetail.map is not a function" is there is logs. I believe I'm having issue with this function call in render method, not sure how to fix that in above code
