How to invoke a nested function

Hi,

I love C# and therefore I'm trying to switch my Angular frontend to a Blazor WebAssemby frontend but not all of the used javascript libraries I'm using in my Angular frontend are available as C# library.

I tried many hours to get the first javascript lib working but without succes.

The first javascript lib I want to use is keycloak.js which contains methods like init, login and logout but I dont know how to call them.

If I call "await JSRuntime.InvokeVoidAsync("Keycloak", new object[] { keycloakClientOptions });" I get into "function Keycloak (config)" but how can I than call init, login or logout?

Thanks

Thomas

I haven't worked with Keycloak, but generally speaking, if you want to invoke a specific JavaScript function, you'd do something like this:
```
string txt = await jsRuntime.InvokeAsync<string>("methods.getText");
```
This would return a string from a JavaScript file that looked something like:
```
window.methods = {
    getText: function () {
        return "Some text";
    }
};
```
You can learn more about invoking JavaScript functions from Blazor at: https://docs.microsoft.com/en-us/aspnet/core/blazor/call-javascript-from-dotnet?view=aspnetcore-3.1
