Apr 24, 2023
🎉In this Blazor JavaScript Isolation Tutorial, we dive deep into Blazor JavaScript Interop to show you how to load a JavaScript module on demand from a Blazor component. This is the essential, modern way to use JavaScript in a Blazor C# app, keeping your code clean, maintainable, and efficient.
📌We'll walk you through the entire process, starting from a new Blazor WebAssembly project. This video is perfect for Blazor developers looking to correctly and cleanly integrate JavaScript functionality without polluting the global namespace.
In this tutorial, you will learn:
âś…How to create a dedicated JavaScript module and export functions.
âś…How to inject IJSRuntime into your Blazor component.
âś…The correct way to import your JS module using import inside the OnAfterRenderAsync lifecycle method.
âś…How to store the module reference in an IJSObjectReference.
âś…How to call your JavaScript function from C# using InvokeVoidAsync (for example, to show an alert).
âś…Why IAsyncDisposable is crucial for cleaning up your JS module reference and preventing memory leaks.
âś…The key benefits of Blazor JavaScript Isolation, such as preventing naming conflicts and creating a local scope.
âś…The difference in file paths when using a Blazor app vs. a Razor Class Library.
