🎉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: ✅How to create a dedicated JavaScript module and export functions. ✅How to inject IJSRuntime into your Blazor component. ✅The correct way to import your JS module using import inside the OnAfterRenderAsync lifecycle method. ✅How to store the module reference in an IJSObjectReference. ✅How to call your JavaScript function from C# using InvokeVoidAsync (for example, to show an alert). ✅Why IAsyncDisposable is crucial for cleaning up your JS module reference and preventing memory leaks. ✅The key benefits of Blazor JavaScript Isolation, such as preventing naming conflicts and creating a local scope. ✅The difference in file paths when using a Blazor app vs. a Razor Class Library.
