Frontend updates without server restart for local development of crowdsourcing task?

[sfillwo]

When locally developing the frontend for a crowdsourcing task in ParlAI, is there any way to publish the frontend changes to display in the browser without having to restart the server?

I've found some information in Mephisto about this for their example static_react_task, but it does not seem to be applicable to the example crowdsourcing tasks in ParlAI (e.g. the mephisto.blueprint.link_task_source config parameter does not exist in model_chat task). I'm not sure if ParlAI has some analogous documentation somewhere, but I am having difficulty finding it if it exists.

Hi @sfillwo, @pringshia put together the link_task_source setup for the static_react_tasks. This setup is successful primarily because the static react tasks don't have any live state that needs to be restored upon a refresh (whereas ParlAI has previous chat turns, and refresh behavior wasn't always consistent). After Mephisto 1.0.0 this type of behavior should be more stable in the ParlAIChatBlueprint as well, so it's something that could be worth looking into.

@pringshia any chance you can provide some direction on the steps required to enabled this for the ParlAI blueprint?

Hi @sfillwo - this is the PR that added in link_task_source support for static_react_task: facebookresearch/Mephisto#509.

The files of note are:

• mephisto/abstractions/blueprints/static_react_task/static_react_blueprint.py
• mephisto/abstractions/blueprints/static_react_task/static_react_task_builder.py

You are correct that this configuration isn't available for the ParlAIChatBlueprint (for the reasons Jack mentioned above - though with Mephisto 1.0 it's more reasonable to add this in).

One option here would be to mimic the implementation above and add it to ParlAIChatBlueprint in the Mephisto repo. Do you feel comfortable opening up a PR with this?
