调研方向

Start by reading the original discussion in issue #1134 and the use_messenger hook plans linked from pull request #881. Determine whether ref support should use client-server communication or a server-side approach; done means an agreed, feasible equivalent to React's canvas ref behavior.

描述

Original discussion: #1134

Current Situation

With several tags such as canvas, ReactJS will "fill in" the context into the ref=... you provide. We currently do not have an equivalent feature in ReactPy. Currently, all props provided to ReactPy are serialized and sent to the client as-is.

Currently we have no mechanism that would enable ReactJS/ReactPy to intelligently "fill in" this ref. To add compatibility for this feature, ReactPy would need to start treating reactpy.html.canvas["ref"] as a unique prop.

Proposed Actions

In all likelihood, creating an equivalent API to ReactJS <canvas ref=... /> would rely on our future plans for a use_messenger hook to allow for arbitrary client->server real-time communication.

There's also a chance we develop this fully server-sided, but that's probably not technologically feasible.
