Best Practices for Improving Syncfusion® Blazor App Performance

20 Aug 20251 minute to read

Enhancing the rendering performance of Syncfusion® Blazor apps involves implementing the following best practices.

Use Individual NuGet Packages

Opt for individual Syncfusion® NuGet packages for specific components. This approach allows you to selectively include only the necessary components, minimizing overhead. For detailed information, refer to Benefits of Using Individual NuGet Packages.

Reduce Script Reference Size

The overall syncfusion-blazor.min.js script reference may be redundant. Instead, consider employing the following solutions to include only the required scripts for rendering Syncfusion® components.

Use Optimized CSS Themes

To reduce CSS payload and improve rendering speed, use optimized CSS themes provided by Syncfusion. These themes are tailored to include only the styles required for the components you use. Learn more at Optimized CSS Themes
