Web modules allow you to write backend functions that you can easily call from the frontend. The following describes how to create, export, and call web module functions, also known as web methods.
The way you add a web module file depends on which IDE you're using.
To add a web module file to your site in the editor:
Navigate to Public & Backend in code sidebar.
Hover over the Backend heading, click the plus icon , and then select Add web module.
This action creates a web module file with a .web.js
extension.
To add a web module file in the Wix IDE or your local IDE:
Create a new file in the backend-modules
directory and name it with the .web.js
extension.
