Make a Weather App Using React Bootstrap OpenWeatherMap API

npx create-react-app weatherapp
cd weatherapp
npm i bootstrap

App.js

import React from "react";

import Titles from "./components/Titles";
import Form from "./components/Form";
import Weather from "./components/Weather";

const API_KEY = "###yourapikey###;

class App extends React.Component {
  state = {
    temperature: undefined,
    city: undefined,
    country: undefined,
    humidity: undefined,
    description: undefined,
    error: undefined
  }
  getWeather = async (e) => {
    e.preventDefault();
    const city = e.target.elements.city.value;
    const country = e.target.elements.country.value;
    const api_call = await fetch(`http://api.openweathermap.org/data/2.5/weather?q=${city},${country}&appid=${API_KEY}&units=metric`);
    const data = await api_call.json();
    if (city && country) {
      this.setState({
        temperature: data.main.temp,
        city: data.name,
        country: data.sys.country,
        humidity: data.main.humidity,
        description: data.weather[0].description,
        error: ""
      });
    } else {
      this.setState({
        temperature: undefined,
        city: undefined,
        country: undefined,
        humidity: undefined,
        description: undefined,
        error: "Please enter the values."
      });
    }
  }
  render() {
    return (
      <div>
        <div className="wrapper">
          <div className="main">
            <div className="container">
              <div className="row">
                <div className="col-xs-5 title-container">
                  <Titles />
                </div>
                <div className="col-xs-7 form-container">
                  <Form getWeather={this.getWeather} />
                  <Weather 
                    temperature={this.state.temperature} 
                    humidity={this.state.humidity}
                    city={this.state.city}
                    country={this.state.country}
                    description={this.state.description}
                    error={this.state.error}
                  />
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>
    );
  }
};

export default App;

Here you need to replace the openweathermap api key.

After that, make a components folder and inside this you need to make

Form.js

import React from "react";

const Form = props => (
 <form onSubmit={props.getWeather}>
  <input type="text" name="city" placeholder="City..."/>
  <input type="text" name="country" placeholder="Country..."/>
  <button>Get Weather</button>
 </form>
);

export default Form;

Titles.js

import React from "react";

const Titles = () => (
 <div>
  <h1 className="title-container__title">Weather Finder</h1>
  <h3 className="title-container__subtitle">Find out temperature, conditions and more...</h3>
 </div>
);

export default Titles;

Weather.js

import React from "react";

const Weather = props => (
 <div className="weather__info">
  { 
   props.city && props.country && <p className="weather__key"> Location: 
    <span className="weather__value"> { props.city }, { props.country }</span>
   </p> 
  }
  {  
   props.temperature && <p className="weather__key"> Temperature: 
    <span className="weather__value"> { props.temperature } </span>
   </p> 
  }
  {  
   props.humidity && <p className="weather__key"> Humidity: 
    <span className="weather__value"> { props.humidity } </span>
   </p> 
  }
  {  
   props.description && <p className="weather__key"> Conditions: 
    <span className="weather__value"> { props.description } </span>
  </p> 
  }
  { 
   props.error && <p className="weather__error">{ props.error }</p>  
  }
 </div>
);

export default Weather;
