Let's add a function that will take a YouTube channel ID and a YouTube Data API key as input that will be sent from the frontend of the Anvil app. If you are a paid Anvil user then you will also have access to a large number of Python libraries. Here you can add the Python functions that can receive and send data to the frontend. To access the server code editor, click on the 'App' icon in the left-sidebar and under 'Server Code' section click on the 'Add Server Module' button to open the server code editor. So, we will add a Label element just below the submit button and change its variable name to 'channel_info' for convenience.Īnvil allows its users to write both client-side (front-end) code as well as server-side (backend) code. The output will be sent back to the frontend for the user to consume. The user inputs will be sent to the Anvil server where we will create a Python function that will process the inputs and generate some output. The objective of this web app is to take some input from the user and show some output to the user on the frontend. Now in this tutorial, we will write the client-side and server-side code for our app so that it can take inputs from the user, i.e., a YouTube channel ID and a YouTube Data API key, then use the inputs to fetch the channel's information with the help of the YouTube Data API. ![]() Below is the screenshot of the final UI of our app. In the article Create Front-End of a YouTube Web App using Anvil, we learned to build the user interface (UI) of a simple web app in Anvil.
