WeatherApp (no mobile version yet) is my first Vanilla JS project that has search engine, API integration, wind speed, weather description,weather icons, forecast and unit conversion. Everything that's included in its code is fully working (no fake data). You can see the forecast for your current location by clicking home icon.
It is a landing page from scratch about ptotein shakes cuz I am passionate about this topic. The page was created using HTML and CSS, ncludes a user interaction.
