chore(website): preserve RulesTable filters state in searchParams #6568

Addresses an existing open issue: fixes Website: Sync Supported Rules filter state in the URL #6171
That issue was marked as accepting prs
Steps in Contributing were taken

Overview

Howdy! 👋

I added syncing rules table filters state to URL search params, and I wrote two test cases for it.

Solution

There are two tables, so I serialised the state to two search params, one for each table

supported-rules,
and extension-rules.

Each value is list of categories concatenated with dashes -.

If FilterMode is "include", we include the category as is

supported-rules=recommended-fixable

If FilterMode is "exclude", we prefix it with x. (We can't use ! in the URL.)

supported-rules=xrecommended-strict-xfixable

I grouped the state of filters into one objects so it's easier to stringify.

Non-solutions

I initially just added a useEffect to update search params after the state change, and useIsomorphicLayoutEffect, but the problem was that the initial state would be written to the URL before it was read. I ended up moving writing to the URL to the changeFilter function exported from useRuleFilters hook.

We need useIsomorphicLayoutEffect to read from the URL instead of just using the state initialiser, because initialising different state in SSG and post-hydration would give us a hydration mismatch.

Alternative solution

I noticed Docusaurus uses React Router, so in 7c2e81a I removed setState and synchronization and move the entire state to useLocation, what in theory sounded better, because we'd just keep it in one place. Unfortunately, this got me a bug where the state wasn't re-read post hydration (useLocation doesn't rerender again?) and I needed a layout effect again, so I ended up just reverting this change.

It seems that the tests are failing, because they wait for the deploy preview and they timeout before it deploys.

😍 thanks for adding this in!

JoshuaKGoldberg

Yup, this looks great. Thanks for sending it in @hasparus!

Just one suggestion on refactoring RulesTable<>useRulesFilters a bit. What do you think?

I'm down to merge as-is if you don't like the suggestion, or make it myself if you don't have time.

+  );


[Cleanup] I'm not a big fan of hardcoding IDs on boolean logic. It tends to break over time, and makes it harder to understand where the IDs come from. How about giving the RulesTable component a mandatory id prop that's then passed directly to useRulesFilters?

I agree about hardcoding is no boolean logic, but I feel that

<RulesTable id="extension-rules">

might be a bit confusing given that the heading above receives id attribute from the markdown pipeline.

How about a prop ruleset: "supported-rules" | "extension-rules" that would subsume the boolean flag and be usable as a search param key?

Yeah I like that a lot!

I added it in 642031f, but it seems there are indirect codecov changes that are failing the CI. Do you think it's connected to my change?

We can ignore codecov for these website PRs. We don't have great unit test coverage on it anyway. 🤷

@JoshuaKGoldberg The deploy has finished in 3 minutes, but the status check's been hanging for 19 hours. Is there a way we can stop it or restart it? This seems like a bug in the Netlify integration.

@Skn0tt sorry for pinging you here, but I couldn't find a contact button at https://app.netlify.com/sites/typescript-eslint/deploys/64131d041e22810009b38f2c.
Who should I bother when the Netlify GitHub integration acts out?

The implementation looks mostly good to me, but as some extra reading, you may want to try useSyncExternalStore (interesting read) ^^

You can replace window.location with useLocation() so you get SSR safety for free

I expected useLocation() to trigger re-renders whenever the location changes, as the docs would suggest: https://reactrouter.com/en/main/hooks/use-location

So using location from useLocation here wouldn't be the same logic, right?
And I'm in a useLayoutEffect which does not run on the server, so accessing window.location works.

Could you tell me more what do you mean by "SSR safety for free"?

Notice that I had rewritten this logic to react-router specific hooks, what I described in "Alternative solution" in the original post. It turned out to be buggy and harder to reason about than the less elegant, naive solution with setState and useLayoutEffect, so I reverted that change — 786557f.

Nice article! Do you think I should rewrite this PR to use useHistorySelector presented in the post?

I'm okay either way! I don't have strong opinions on this, and TBH my React is getting a bit rusty these days. Just thought you may be interested—since effects don't work well with SSR.

Could you tell me more what do you mean by "SSR safety for free"?

I mean you don't have to use useIsomorphicLayoutEffect and read from a client-only API inside. useLocation is available both server-side and client-side, so it's more robust.

Well, yes, that's true, but then we shouldn't use useState, because a change to the location will already re-render the component. Would you agree?

Would you prefer if I went back to the state from 7c2e81a? and write end-to-end tests to ensure it works?

This reverts commit 7c2e81a.

this looks great, if you fix those linting errors i think we are ready to merge

Sorry for getting back so late, I was on PTO the past weeks. Not sure what happened here, but it looks like things are alright now? Let me know if not, and i'll see how I can help :)
