18 Dec 202312 minutes to read

This section provides information about the script isolation process and how to reference scripts from CDN, Static Web Assets and Custom resource generator (CRG) for Syncfusion Blazor Components.

NOTE

The javascript interop files needs to be added to support the features that can’t be implemented in native blazor.

CDN Reference

You can refer the Syncfusion Blazor scripts through the CDN resources.

For Blazor Web App, reference scripts in ~/Components/App.razor file.
For Blazor WASM App, reference scripts in ~/wwwroot/index.html file.
For Blazor Server App, reference scripts in ~/Pages/_Layout.cshtml file for .NET 6 project and in ~/Pages/_Host.cshtml file for .NET 7 project.

Syncfusion Blazor components are available in CDN for each version. Make sure that the version in the URLs matches the version of the Syncfusion Blazor Package you are using .
