PostMessage / WebRTC data source

[benfoxall]

I might have a bunch of data loaded in my own web page, and I want to be able to "open in Foxglove", without having to upload that content to a file server.

Two ways I could imagine this working

1. postMessage to window / iframe

const ref = window.open('https://studio.foxglove.dev/?transferOrigin=my-page.com')

ref.postMessage(myData, 'studio.foxglove.dev', [transfer])

Open a new window, use that reference to send data to foxglove with post. Could be quite efficient and quick to prototype, though might hit problems with ad blockers.

2. WebRTC

<a href="'https://studio.foxglove.dev/?signalToken=xyz" target="_blank">Open</a>

Open foxglove to connect a peer-to-peer datchannel to the source window, then the content could be streamed across (maybe reusing the ws-protocol).

This would require a signalling server etc, though it could open up a bunch of other use cases (being able to share your data to other people, or connecting to robots without having to expose http ports).
