Geolocation Service for Blazor
A lightweight and efficient Blazor service for interacting with the Browser's Geolocation API. This service uses JS Interop with Lazy Loading to ensure that JavaScript resources are only loaded when needed.
Features
- Lazy Initialization: The JavaScript module is loaded only upon the first method call.
- Permission Handling: Includes a built-in check to verify if the user has granted geolocation permissions.
- Memory Management: Implements
IAsyncDisposableto properly release JavaScript object references. - Robust Error Handling: Internal try-catch blocks prevent JS runtime errors from crashing the .NET process, logging issues to the browser console instead.
Registration
Add the service to your Dependency Injection (DI) container in Program.cs:
builder.Services.AddGeoService();
Usage
Inject the IGeolocationService into your Razor components to retrieve the user's coordinates.
@page "/location"
@inject IGeolocationService GeolocationService
<PageTitle>Location Tracker</PageTitle>
<h1>Geolocation</h1>
@if (currentPoint != null)
{
<p>Latitude: @currentPoint.Latitude</p>
<p>Longitude: @currentPoint.Longitude</p>
}
<button class="btn btn-primary" @onclick="GetUserLocation">
Get My Location
</button>
@code {
private ILatLong? currentPoint;
private async Task GetUserLocation()
{
bool isGranted = await GeolocationService.GetGeoLocationGrantedAsync();
if (isGranted)
{
currentPoint = await GeolocationService.GetPositionAsync();
}
else
{
// Handle permission denied or prompt user
Console.WriteLine("Location access denied.");
}
}
}
