@rmorshea This is fully functional but currently has no eviction/expiration strategy implemented. Let me know what you think.

[rmorshea]

Will take a look tomorrow

[rmorshea]

Overall LGTM. Perhaps we could add a test which passes a parameter to a component that isn't JSON serializable?

[Archmonger]

The reconnect variable has been changed to better describe the new behavior. Also, the rename helps in preparation for reactive-python/reactpy#525

In the future, I hope to introduce a IDOM_RECONNECT_INTERVAL setting as well.

Changelog in the PR's description has been updated.

[Archmonger]

I've added tests for the component parameter cleanup logic

[Archmonger]

@rmorshea This has security fixes, so I'd like to get this out soon if possible.

[Archmonger]

I removed the version bump from this PR.

I will create a follow-up PR that bumps IDOM to 1.0.0 and Django-IDOM to 3.0.0.

[rmorshea]

Will review tomorrow.

[rmorshea]

Generally approve, just few minor nits/comments

[Archmonger]

Let me know if we're okay with the approach on the 3 unresolved comments

[rmorshea]

I think everything looks good to me.
