Question
I am learning how to use Blazor Interop, but it has changed recently, so I don't have any easy example to learn from I copied a code from a working example and would like to change it to the new interop here is the code from Blazor 0.4.0 from .js file
Blazor.registerFunction('saveToken', token => {
window.localStorage.setItem('jwt', token);
console.log("Authentication token has been stored.");
return true;
});
And this from the Blazor page .csthml functions
RegisteredFunction.Invoke<bool>("saveToken", token);
I have already read the Blazor Doc Interop https://blazor.net/docs/javascript-interop.html and the example was very easy to follow, but with localstorage I don't know how
Accepted Answer
In 0.5+, you just make the function visible through window.
window.saveToken = token => {
window.localStorage.setItem('jwt', token);
console.log("Authentication token has been stored.");
return true;
};
JsRuntime.Current.InvokeAsync<bool>("saveToken", token);

Or, you can just use a Nuget package that already does the interop for you like this one: https://github.com/BlazorExtensions/Storage
