Just found out that someone made a javascript for google analytics which helps single page apps like blazor to correctly tracks urls you visit, external links you open and other features here https://github.com/googleanalytics/autotrack it works really well for me now
The namespace is Blazorx not Blazor. This needs to be changed in all samples.
I followed the setup info you provided.
I added NavigationTracker to the App.Razor
Sorry, there's nothing at this address.
and I added the JS to index.html
<script src="_content/Blazor-Analytics/blazor-analytics.js"></script>I added the service to Program.cs of the client
builder.Services.AddGoogleAnalytics("XXXXXXXXX");
But I am still not getting individual page view info in Google Analytics. It just registers the application was loaded/accessed.
I also experimented with
await Analytics.TrackEvent("PageView", null, "PageName");
in a couple of pages to see if calling the specific event would help but no joy.
Any suggestions or recommendations ?
Hi, I added this library to a small project I'm working on and it doesn't seem to do anything at all when targeting WebAssembly.
Project details:
Neither running on local or publishing on the web shows anything in Analytics. If I copy and paste the code provided by Google into the project's index.html, it shows data when run from both places.
When passing event value/category/label etc the parameters are passed incorrectly. In https://github.com/isc30/blazor-analytics/blob/master/src/Blazor.Analytics/GoogleAnalytics/GoogleAnalyticsStrategy.cs#L63 you call the interop with
await _jsRuntime.InvokeAsync<string>(
GoogleAnalyticsInterop.TrackEvent,
_trackingId, eventName, eventValue, eventCategory);
But in https://github.com/isc30/blazor-analytics/blob/master/src/Blazor.Analytics/GoogleAnalytics/Resources/GoogleAnalyticsInterop.ts#L46 the parameters are in a different order.
export function trackEvent(event: string, eventCategory: string, eventLabel: string, eventValue: string)
{
gtag("event", event, { event_category: eventCategory, event_label: eventLabel, value: eventValue });
if(this.debug){
console.log(`[GTAG][Event trigered]: ${event}`);
}
}
Looking at the history it seems there were two functions for trackEvent in GoogleAnalyticsInterop.ts
but one was removed in 36b752f#diff-6cdb5d4488ebfb7b2a0f7d2e59fea40eea0d17ed2bf53c4f5186d16950b06d9e. The removed one matched the arguments being passed in correctly.
Not sure how you want to resolve this but should be quite straightforward. Let me know if you'd like a pull request for it.
3.0.0.2 build from Nuget
Running server side blazor 3.1 (.net core 3.1.1)
Title says it all, getting a 404 for the blazor-analytics.js
Roll back to 3.0.0 and now blazor-analytics.js comes through fine, everything else seems fine so far.
Request URL: https://localhost:44379/_content/Blazor-Analytics/blazor-analytics.js
Status Code: 404
I followed all the instructions for server side Blazor. How does the file get out of the nuget package and into the _content folder? I can see the file in wwwroot folder (not in any other folder, just at the root) in solution explorer but it's not actually there on the file system - it's full path is a path to the NuGet folder.
Any ideas of things I can investigate?
Documentation on the readme file is inaccurate. I cannot pass in an event object. Why was this taken out?
Hi,
your app running in Azure sometimes gets the following exception:

Hi, I'm successfully using your NuGet package but my website is now accepting two country domains and I need to conditionally configure the scoped service with a Google key depending on the domain of the http request. I guess I should first add the scoped service with its parameterless constructor and configure the service with the right key after building the WebApplication on Program.cs. May you publish in the Readme file an example of how to configure it if even possible?
Hi,
Small ask but can would it be possible to get a disclosure added to the package? I am using this package in a Blazor WASM app and trying to get google to approve our ads on the site and one of the final hurdles are proper software disclosure on all .dll that the client downloads.
Currently this package is one that is flagged by Google Ads.
Thanks
Hi,
I am using Blazor Server Side app with .NET 6.
I tried to setup extension, but I got still 404 error. I know some while ago it was similar issue.
Maybe you know why it still appears?
GET https://www.mysite.com/_content/Blazor-Analytics/blazor-analytics.js net::ERR_ABORTED 404 (Not Found)
like explained here:
https://developers.google.com/analytics/devguides/collection/gtagjs/cross-domain
gtag('config', 'GA_MEASUREMENT_ID', {
'linker': {
'accept_incoming': true
}
});
Hello, first of all, thank you for building this <3.
I'm using Xunit together with Bunit to write unit tests. (https://bunit.egilhansen.com/docs/providing-input/inject-services-into-components.html#injecting-services-in-c-based-tests)
To 'mock' an service injection they use a concrete class
ctx.Services.AddSingleton<IWeatherForecastService>(new WeatherForecastService());
I tried to
ctx.Services.AddSingleton<IAnalytics>(new ?);
Is there anything I could use for the IAnalytics. My tests now fail due the error
System.InvalidOperationException : Cannot provide a value for property 'Analytics' on type 'Pay1Euro.Client.Pages.Counter'. There is no registered service of type 'Blazor.Analytics.IAnalytics'.
My question is : In any project of yours, were you able to test this, and how did you do this?
My very basic Counter page that i'm trying to test.
@page "/counter"
<h1>Counter</h1>
<p>Current count: @currentCount</p>
<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>
@code {
private int currentCount = 0;
[Inject]
private Blazor.Analytics.IAnalytics Analytics { get; set; }
private void IncrementCount()
{
currentCount++;
Analytics.TrackEvent("Increment", currentCount.ToString(), "CountPage");
}
}
This may be an issue separate from Blazor-Analytics (let me know if you agree). When trying to view the BlazorClient site in preview mode using GTM, the expected panel does not appear. Is this just an incompatibility with Blazor? I'm not sure if GTM needs to inject additional js to make this functionality work or if it is supposed to be included in the initial analytics scripts from the head element to insert the preview/debug iframe.
Add PR checks for compilation
Create a demo application
Is there any way to disable tracking certain pages? It would be nice to have some way to disable it when not needed.
It would be nice to pass custom additional parameters to Google Analytics, such as customer number.
Thanks
Preview 9 replaced IUriHelper
with NavigationManager
which throws a
System.TypeLoadException: "Could not load type 'Microsoft.AspNetCore.Components.IUriHelper' from assembly 'Microsoft.AspNetCore.Components, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'."
At startup because
Blazor.Analytics.GoogleAnalytics.GoogleAnalyticsComponent
is trying to load IUriHelper
Here:
Hey there many thanks for this awesome library. I would recommend trying to load scripts using Js Isolation way. This way consumers don't need to add scripts in index.html
. What's your thoughts on this?
Looks Like it's not working for Blazor Web App 8.0
I have created a Blazor web app with both server and web assembly modes.
But it not recorded in analytics.
If you provide one working sample for Blazor web app 8.0 with both server and web assembly in a client project.
Is it possible to track an event like this for example:
https://developers.google.com/gtagjs/reference/ga4-events#select_content
Why is "eventValue" an integer for TrackEvent (https://github.com/isc30/blazor-analytics/blob/master/src/Blazor.Analytics/GoogleAnalytics/GoogleAnalyticsStrategy.cs)?
I'm happy to do a PR if changes are needed to make it work.
Hi,
great package. I was wondering since Google now has the GA4 properties instead of the old Universal Google Analytics ID.
They call it the measurement ID now for GA4. Can i pass that ID now also in this package and does that work?
thanks
I am currently using the library but I have a problem when entering the TrackingId since I do not have it when registering the service in the startup since I am also using the Finbuckle.MultiTenant library
I see that they have the service registration without the trackingId, how to use the service when the service only registers you in the following way?
services.AddGoogleAnalytics();
Hi,
we need a switch to turn on/off Google analytics. The reason behind this is here in Germany we have GDPR that states that the end user must be able to switch off analytics tracking through consenting or rejecting cookies.
That means when the user doesn't consent to cookie policy the analytics mustn't be activated.
Could you implement this?
Thanks
Sven
When I'm monitoring the "real time" of Google Analytics, it looks like the NavLink transitions are not being tracked.
Only when I refresh the page in the browser, the page views are tracked.
Is this normal?
Also, is there a solution?
gtag('set', 'linker', {
'domains': ['domain1.de', 'domain2.de', 'domain3.de']
});
I just wanted to ask if its possible to enable the tracking again after initially disabling it. I want to wait on a response from CookieBot if the statistics cookies have been accepted and before that they have to be disabled.
Thanks!
In v3.1.1 the tsconfig.json file seems to have been accidentally included in the Nuget package. This causes Visual Studio to generate errors when it can't find anything to compile. Deleting tsconfig.json from the nuget package cache suffices as a workaround.
Hi,
is there possibility to add events?
The console.log
statements are very useful for debugging, but I'd like them to not be logged in production. Can we have a way to opt-in to logging but have it not logged by default?
The library works great btw, thank you!
with the version from NuGet I still get the previous error listed at #6 regarding iurihelper vs NavigationManager.
Pulling the code from github and compiling myself I now get an issue with:
JavaScript interop calls cannot be issued at this time. This is because the component is being statically rendererd. When prerendering is enabled, JavaScript interop calls can only be performed during the OnAfterRenderAsync lifecycle method

I don't have a tracking id during development or when deploying for self-hosting in a container.
When I don't provide a tracking id, I get a run-time error on the console and from the Blazor dev UI that the "tracking code is invalid".
I get a different error when I don't do a AddGoogleAnalytics
at all.
How is this to be handled?
Hi,
how is possible to use the package from API in ASP.NET Core?
Is also possible to track a single user passing any ID?
Thank you.
Currently, only GTag is supported but the architecture allows any kind of integrations.
Keeping this issue alive until we gather a list of the most used analytic APIs.
List of possible candidates:
This component is totally Compliance with GA4?
Best Regards,
Ivan,
thanks for putting this together. Really handy.
I've followed your instructions to include this in a Blazor client (WASM) project.
I think there is a problem with the component.
On page load I get an unhandled error in the UI and looking at the browser debugging console I see:
Unhandled exception rendering component: Cannot provide a value for property 'Analytics' on type 'Blazor.Analytics.Components.NavigationTracker'. There is no registered service of type 'Blazor.Analytics.IAnalytics'.
Any ideas?
