#23 React Js Challenge Day 23 | Weather app using react js (openweathermap api tutorial)

Today we will be building a weather app using react js and openweathermap api. This tutorial will guide you through the process of creating a simple yet functional weather app that can display the current weather information for a given location.

Prerequisites

• Basic understanding of HTML, CSS, and JavaScript
• Node.js and npm installed on your machine
• Knowledge of react js

Setting up the project

First, let’s create a new react project using create-react-app. Open your terminal and run the following command:

npx create-react-app weather-app

Once the project has been created, navigate to the project directory and open it in your code editor.

Getting the API key

In order to fetch weather data, we will be using the openweathermap API. Head over to their website and sign up to get an API key. Once you have the key, store it in a safe place as we will be using it in our app.

Building the weather app

Now that we have our project set up and API key ready, let’s start building our weather app. We will be creating components to display the weather information and fetch data from the openweathermap API using axios.

Step 1: Creating the components

Start by creating components for displaying the current weather, a search input for location, and a button to fetch weather data. You can also add a component for displaying error messages if the location is not found.

Step 2: Fetching data from the API

Use axios to make a get request to the openweathermap API using the API key and the user’s input location. Once the data is received, update the state and display the weather information on the app.

Conclusion

Congratulations! You have successfully created a weather app using react js and openweathermap API. You can further customize the app by adding more features such as a 5-day forecast, temperature conversion, and styling the UI. Keep exploring and building more projects to enhance your skills in react js.
