About Events & Service Plugins and the SDK

You can now use the Wix JavaScript SDK instead of Velo APIs for most functionality when developing sites or building apps with Blocks. This marks the beginning of a gradual transition from using Velo APIs to using the next generation SDK. You are encouraged to start using the SDK in all new and ongoing development projects.

However, the following APIs are not yet supported in the SDK:

• Event handlers and service plugins when using Blocks or when developing sites.
• Data hooks.
• Routers.

To use the functionality of these APIs, continue to use the existing Velo APIs.
