A Blazor JavaScript interop for dynamically loading scripts, styles, and modules
Overview
The ResourceLoader class is designed to manage the loading and initialization of scripts, styles, and JavaScript modules in a Blazor application. It provides methods to asynchronously load scripts and styles, wait for variables to be available, and manage the lifecycle of JavaScript modules.
It ensures that each resource is only loaded once (through this interop), even with multiple concurrent calls.
To import a JavaScript module, use the ImportModule method:
var module = await resourceLoader.ImportModule("moduleName");
You probably want ImportModuleAndWaitUntilAvailable, as that waits until the module is loaded, and accessible:
// 'ResourceLoader' is the name of the export class
var module = await resourceLoader.ImportModuleAndWaitUntilAvailable("Soenneker.Blazor.Utils.ResourceLoader/resourceloader.js", "ResourceLoader");
Waiting for Variables
To wait for a JavaScript variable to be available, use the WaitForVariable method:
Soenneker.Blazor.Utils.ResourceLoader
