HTML5 WebUSB API implementation for Microsoft Blazor
Blazor Extensions are a set of packages with the goal of adding useful things to Blazor.
This package wraps HTML5 WebUSB APIs.
Install-Package Blazor.Extensions.WebUSB
- First add the USB services on Blazor
IServiceCollection
:
public void ConfigureServices(IServiceCollection services)
{
services.UseWebUSB(); // Makes IUSB available to the DI container
}
- On your
_ViewImports.cshtml
add the using entry:
@using Blazor.Extensions.WebUSB
- Then, on your
.cshtml
inject theIUSB
:
@inject IUSB usb
And then use the usb
object to interact with connected USB devices thru your Blazor application.
Define a property of type IUSB
and mark it as [Injectable]
:
[Inject] private IUSB _usb { get; set; }
Then use the _usb
variable to interact with the connected USB devices.
Note: For now, you have to call await IUSB.Initialize()
once in your application. This is a temporary requirement and we are looking on a better way to automatically register to Connect/Disconnect events.
Please feel free to use the component, open issues, fix bugs or provide feedback.
