Since Bswup is taking care of the lifecycle of the application, we need to disable the autostart of the Blazor by adding autostart=false to the Blazor script tag:

<script src="_framework/blazor.web.js" autostart="false"></script>

Or for the standalone template:

<script src="_framework/blazor.webassembly.js" autostart="false"></script>

The next step is to add and configure the bit Bswup's script tag itself:

<script src="_content/Bit.Bswup/bit-bswup.js"
        scope="/"
        log="verbose"
        sw="service-worker.js"
        handler="bitBswupHandler"
        blazorScript="_framework/blazor.webassembly.js"></script>

This script tag as shown above, has some options:

scope: The scope of the service-worker (read more).

log: The log level of the Bswup logger. available options are: info, verbose, debug, and error (coming soon).

sw: The file path of the service-worker file.

handler: The name of the handler function for the service-worker events that explained here.

blazorScript: The file path of the Blazor's js script file.

Note: You can remove any of these attributes which makes the bit Bswup to use the default values mentioned above.
