Not work in pyodide #553

Open Nanguage opened 11 months ago

Nanguage commented 11 months ago

I tried to run imjoy-rpc in the pyodide environment:

import micropip
await micropip.install("imjoy-rpc")
from imjoy_rpc import api

class Plugin:
    async def setup(self):
        print("setup")

    async def run(self, ctx):
        print("run")
        print(ctx)

api.export(Plugin())

but the following error occurred.

Traceback (most recent call last):
  File "<console>", line 1, in <module>

    self._post_message = js.sendMessage

AttributeError: sendMessage

Do I need to make some settings in the JS environment? If so, how should I do it?

You will need to load the imjoy core in the web page, so imjoy-rpc can connect to it. In that case, you can just use imjoy-core and load a plugin with type=web-python, this will automatically run Python plugin in pyodide.

If you don't want to do anything in the pyodide env, it's easier to just use imjoy_rpc.hypha to connect to the hypha server. Then you will have a system similar to imjoy.
