  from the AccuWeather API.Create an AccuWeather API KeySign up for a free AccuWeather developer account athttps://developer.accuweather.com/. Within your account, create a new app by selecting MY APPS on the top navigation menu to get your unique API key.
  AccuWeather API is a web API that provides real-time weather data and forecasts. Developers can use this API to integrate weather information into their applications, websites, or other projects.Change directory to accuweather-api
  
  $ cd accuweather-api
  Set your AccuWeather API key using the .env file:
  TipTo prevent conflicts, ensure that any existing environment variables named API_ENDPOINT_BASE or ACCUWEATHER_API_KEY are removed before modifying the .env file.Run the following command on your terminal:
  
  unset API_ENDPOINT_BASE
  unset ACCUWEATHER_API_KEY
  Itâs time to set the environment variables in the .env file:
  
  ACCUWEATHER_API_KEY=XXXXXX
  API_ENDPOINT_BASE=http://dataservice.accuweather.comMake sure to populate ACCUWEATHER_API_KEY with the correct value.Install the dependenciesRun the following command to install the required packages:
  
  $ npm install
  This will install all the packages listed in your package.json file. These packages are essential for the project to function correctly.If you encounter any warnings related to deprecated packages, you can ignore them for now for this demonstration.Assuming that you donât have a pre-existing Node server running on your system, go ahead and start the Node server by running the following command:
  
  $ npm run start
  You should see the following output:
  
  > express-api-starter@1.2.0 start
  > node src/index.js
  
  API_ENDPOINT_BASE: http://dataservice.accuweather.com
  ACCUWEATHER_API_KEY is set: true
  Listening: http://localhost:5001Keep this terminal window open.Run the curl command to send a GET request to the server URL.In the new terminal window, enter the following command:
  
  $ curl "http://localhost:5000/api/v1/getWeather?city=Bengaluru"
  By running the command, you're essentially telling your local server to provide you with weather data for a city named Bengaluru. The request is specifically targeting the /api/v1/getWeather endpoint, and you're providing the query parameter city=Bengaluru. Once you execute the command, the server processes this request, fetches the data and returns it as a response, which curl will display in your terminal.When fetching data
