Support WebSocket in HAR

[germanbisogno]

Do you have plans to include WebSockets in the result of harFromMessages?

Since chrome 76, it includes WebSocket messages in HAR exports.

Thanks,

Awesome project!

Hi @germanbisogno thanks for the kind words! Do you have a Chrome trace with a websocket, I can have a look.

Thanks

Or even better a URL with an example, then I can generate the trace myself.

hi @soulgalore , thanks for the quick response, you can setup a node express and play around ws by yourself, exporting the har file from devtools manually after sending some messages to your local server, for example as this page shows https://medium.com/@PubNub/node-js-websocket-programming-examples-f6b8e15f8f85.

Thanks,

The har-format package has the structure needed.

For a reference implementation:
https://github.com/UppaJung/hardy-har/blob/0e1ab29feb847b5078e7af87cc85c440de335ee9/src/HarEntryBuilder.ts#L779-L799

Note: you will need to add the web sockets protocol to the supportedProtocols function.
