Question: Transfering data from window to extension
See original GitHub issueHey, i have a question. I would like to use this implementation of vscode in browser as frontend for lowcode platform. I want to use this in iframe and i want to send data through window.postMessage.
However vscode extension has no access to window object. I tried creating custom command similarly to github1s.vscode.get-browser-url
and i am able to register eventListener on window in this way, but i have no clue how to pass information from callback to extension
Is this even possible?
Thanks for info

I think we can do that:
@mecirmartin
Yes, the extension runs inside a webworker, so we can’t visit the
window
object directly. And the extension host service also runs inside an isolated iframe:https://github.com/conwnet/github1s/blob/master/resources/index.html#L180-L181
We can also use the
postMessage
API inside a webworker (just contact with the extension host service directly), but I think the vscode command maybe better in this case.You can register a command like
github1s.vscode.get-browser-url
in vscode main service, and then the extension can get the data from vscode main service by using the extension API (vscode.commands.executeCommand('github1s.vscode.get-browser-url', ...arguments)
). Noted theReturns
of theexecuteCommand
API is the returned value of the given command(thewindow
object works here) and thearguments
is the data we can get inside an extension context (webworker).https://code.visualstudio.com/api/references/vscode-api#commands
You can also register a command in your extension context using the API (vscode.commands.registerCommand). So that we can call the function which comes from the extension context once the vscode is ready when we are in vscode main service.
Hope the information above can help you.
