Wix Blocks: About Coding in Blocks
3 min read
Wix Blocks is currently open to a limited number of users.
Blocks lets you add Velo code to your widgets and apps. You can add code to an individual widget, as well as code for the entire app.
Visit Blocks Developers Docs
If you are a developer working with Blocks, make sure to visit these sites:
- The WixDocs website, with complete developer documentation for Blocks
- The Velo API Reference website, specifically:
In this overview article, learn more about:
Widget Code
Add code to your widget to provide the following:
- Custom functionality and interactions. Adding Velo code to your widget is just like adding code to a site page in the Wix Editors. Use this to implement your widget's internal business logic. Note that Blocks has a Properties and Events panel for your widget's elements.
- Widget API. Your widget API enables you to add properties, functions and events to the entire widget. These are exposed when your widget is installed on a site (in the Wix Editors) or when it's added inside another widget. Use your widget API with the $widget namespace.
Panel Code
Blocks custom panels have their own code tab to create their logic.
Design a custom panel, connect it to a desired action button and add code to determine what happens in the panel.
Note that Blocks custom panels have designated API references:
Dashboard Code
Add Dashboard pages to your app, to enable site creators to configure your app. Dashboard pages also have have a designated code tab, as well as designated APIs.
Collection code
Blocks allows you to create dataset collections and access them in your app and site. Use the `wix-data` module to work with your collections.
Code Files and Folders
App namespace
To use code files, make sure your app has a namespace
Add frontend or backend code files for your entire app. These are also referred to as "code packages".
To add code to your app:
- Click Public & Backend
icon under the App Structure 
menu. - Select the type of file you would like to add.
Installed App Instance Code
When your app is installed on a site, you can get information about that specific instance. One useful example of that is to learn about the pricing plan of this user.
To do this, use the wix-application module.
