I have made this app using React Hooks, and Openweathermap API.
The way I connected the API is quite simple to understand for a beginner.
We just have to enter the 'CITY NAME' and we`ll get the result of its weather along with date.
Initially, I haven't added much UI and made it simple, but soon I'll add a good sort of CSS.
For more details checkout the source code. Below image is the demonstration of my Weather-App.
