Hello,

the message indicates the script was found otherwise you'd have had a 404, but the MIME type provided by the web server was unexpected (text/html) so Chrome won't execute it for security reason. I've had this issue on Windows and fixing the registry worked for me:

Alternatively, you might try to run a release build in a production-like environment (not using Dart/Flutter's Web server).

On a side note, it seems you're using the latest version of squadron_builder so you can simplify your service class:

@SquadronService()
class LiveFeedService {
  @SquadronMethod()
  Stream<double> pulse() async* {
    var n = 0;
    while (true) {
      yield n.toDouble();
      n += 1;
      await Future.delayed(const Duration(milliseconds: 100));
    }
  }
}

Please note that this service is not interruptible because it lacks a CancellationToken parameter, so once it is listened to, I guess it will run forever you will have to properly cancel the subscription to stop the streaming operation.

Hello, following up on this issue. Did you manage to have it work on the Web?

d-markey commented 10 months ago

Not a Squadron issue / No follow up in the last month --> Closing

sabin26 commented 9 months ago

I am facing the same issue. If it only works in production environment (not tested yet) then it is a productivity killer while developing in debug mode.

d-markey commented 9 months ago

Hello, unfortunately, I don't know why Flutter's dev Web server responds with a 'text/html' MIME type in your case, but that prevents your browser from running the Worker code. Have you checked your browser's dev tools to see what's going on? Maybe the URI to your worker script is incorrect? When using squadron_builder, you can specify the base URL to your worker via the SuqadronService annotation.

I remember I ran into a similar problem when I started this project, but I managed to fix it although I can't remember exactly how. I've added a proper key for ".js" mime type in the Windows registry, and I remember also fiddling with Chrome's security settings. Eventually the problem disappeared.

I have checked my browser's dev tools and here is the stack:

squadron-bug

I am using squadron_builder and I expect it to provide correct Uri to my worker scripts or am I supposed to provide one?

I also tried these steps you mentioned but the key was already present on my windows machine.

  • open key "HKEY_CLASSES_ROOT.js" in the Windows Registry,
  • I assume the "Content Type" key is missing
  • create the "Content Type" key with value "application/javascript"

On Web platform, the Dart code must be compiled to JavaScript and copied to the web output (typically somewhere in the /web folder). This step is not handled by squadron_builder and the baseUrl provided to SquadronService must match the subfolder where the JS lives. squadron_builder will only take care of the file name (appending ".js" to the original Dart file name).

Eg.

dart compile js .\lib\src\my_service.web.g.dart -o .\web\abc\my_service.web.g.dart.js -m

You can refer to https://github.com/d-markey/squadron_sample for an example.

Now to check if your browser found the JS worker, can you check the network tab in Chrome's devtools and look for the entry to the JS worker URI? If the response is a 404 you need to provide the proper baseUrl matching the output of your dart compile js command for your worker.

PS @sabin26 referring to your other issue (passing a Function to a Worker method -- https://github.com/d-markey/squadron/issues/26) please note that this won't work on Web. Functions cannot be transferred to a Web Worker.

I have worked around that issue by not passing a function as an argument to the worker task. I return the Map from the worker and use Model.fromJson in the main thread now.

This step is not handled by squadron_builder and the baseUrl provided to SquadronService must match the subfolder where the JS lives. squadron_builder will only take care of the file name (appending ".js" to the original Dart file name).

Eg.

  • your service is implemented in "my_service.dart"
  • you provide "/abc" as the baseUrl
  • squadron_builder generates several files, including "my_service.web.g.dart"
  • this file contains the target URL to your JS worker: "/abc/my_service.web.g.dart.js"
  • then before running you app in your browser, you need to compile the JS code like this:

dart compile js .\lib\src\my_service.web.g.dart -o .\web\abc\my_service.web.g.dart.js -m

You can refer to https://github.com/d-markey/squadron_sample for an example.

Although I am still stuck on making my worker work on the web, I am no longer getting MIME error by following the above steps correctly. I can see the worker.js on the Network Tab with status code: 200. You can close the issue now. Thank you for your help.
