Never continues to amaze me how I manage to find corner cases of major projects a decade plus into their existence 😭 Today: serving static assets of a Next.js app from an external CDN and instantiating a Web Worker straight up doesn't work. v16.1 it mangles the URL, v16.2 it's a SecurityError. Fml

When would you use this instead of ky? Is it mostly a preference of API style? Or are there distinguishing features, like bring your own fetch?

020

Louis DeScioli @lou.descioli.com · 04/04/2026

Yes, my case where I use this is a query used in a single place. So not re-rendering when data updates elsewhere is n/a. This is a gray area about the rules IIUC. It's an effect, but it's idempotent w/ the cache. Any other suggestions for this pattern, where a parent fetches but a child suspends?

Got a question for you about trying to React.use on a promise from queryClient.fetchQuery bsky.app/profile/lou....

Louis DeScioli @lou.descioli.com · 01/04/2026

@tkdodo.eu related to your work here bsky.app/profile/tkdo... I recently wanted to initiate a fetch in a parent component but then suspend in a child component. Instead of usePrefetchQuery + useSuspenseQuery I came up with this. Child component calls `use` with returned promise. Clever or stupid?

Nice! Looking forward to it. Trying to migrate my team’s workflows to continuous tasks/TUI for day to day dev and this got raised as enough friction to stick current workflow of separate terminal tabs/windows

Louis DeScioli @lou.descioli.com · 22/10/2025

@juri.dev is there some way to search the logs for an @nx.dev continuous task, aside from copy and pasting the entire TUI output into a separate file and searching? Or, is there a way to tail the output for a task(s) to a file? There's the MCP server, but is there a simpler way to see/query logs?

...was counting on being auto-memoized for performance reasons. An innocent change blew up the performance of the whole tree. Handler functions created in the parent that had previously been memoized now changed every render, messing up the memoization of the child components, etc. etc.

Louis DeScioli @lou.descioli.com · 14/06/2025

I think at this point my team and I definitely want warnings, either via eslint or at compile time, when a component won't be memoized. In the real-world situation I'm pulling that sort example from, it was a big, ~1k-line component that renders a couple costly sub components, each of which...

Same issue though when copying and using sort playground.react.dev#N4Igzg9grgTg...

Louis DeScioli @lou.descioli.com · 14/06/2025

It's so silent and surprising that it has me considering whether my guidance to my team should be to stop using useMemo altogether, just use IIFEs and let the Compiler do any and all memoizations

100

Louis DeScioli @lou.descioli.com · 14/06/2025

Will this help situations where the Compiler bails out on certain uses of useMemo? I've been surprised a few times in the past couple weeks where adding a useMemo that follows all rules and looks harmless accidentally de-optimized a component playground.react.dev#N4Igzg9grgTg...

Louis DeScioli @lou.descioli.com · 08/06/2025

We keep having to 'use no memo' in components that use @tanstack/react-table, though. I think there's something with the useReactTable hook that is relying on over-rendering/breaking some rule of React. Haven't gotten to the bottom of that

100

Louis DeScioli @lou.descioli.com · 08/06/2025

I enabled it February on a very large Next.js project I joined that had little to no memoization. Re-renders were so bad taking a profile would fail most of the time. It worked wonders! Almost no one on the team knew about it! I was very surprised. Next.js making it an "experiment" doesn't help

@juri.dev I'm curious, with the TS Go future how has that changed the @nx.dev team's thinking for TS monorepo setups? You think package manager + references setup is still the best default, or single project + path aliases and adopt references as needed?

Also how can I get suggested imports working again? That functionality seems to be broken in VSCode with the references+workspaces setup, using either pnpm or npm. Having to manually write out import paths is unfortunate. Is that a known issue?

Louis DeScioli @lou.descioli.com · 09/02/2025

Looks like the esbuild, swc and rollup executors are all set to not allow generatePackageJson github.com/search?q=rep... Maybe this is coming in Nx v21? 🤞 This is a hard blocker for being able to adopt a references+workspaces setup.

@juri.dev another question when using the new @nx.dev TS setup. I have Node.js apps built using the esbuild executor, using the generatePackageJson option to install only that app's deps in prod. With the new setup there's an error about that option being unsupported 🫤 What's a viable alternative?

@juri.dev, I just finished doing a deep dive on all the latest Nx & TS work. Really exciting stuff! When following the new suggestion to use references+workspaces, is the withNx bit for configuring a Next.js app nx.dev/recipes/next... even needed anymore?

Love this! I just tried this out on my site and caught some accidental enlargement in places other than the first paragraph, e.g. an article where I had list items in a ul. Solved it by using `p:first-of-type` instead of `:first-child` 👍

120

Louis DeScioli @lou.descioli.com · 28/01/2025

Yup, I’m tracking the same threads about it. Maybe this will be the year reading from a big context is performant instead of a pitfall! 🫠🤞

010

Louis DeScioli @lou.descioli.com · 28/01/2025

I haven't put the compiler through its paces on these cases yet, though, so I could be happily wrong!

110

Louis DeScioli @lou.descioli.com · 28/01/2025

I think so. It’s the assumption of the compiler entirely replacing useMemo for cases that involve reselect that doesn’t feel entirely plausible, yet.

120

Louis DeScioli @lou.descioli.com · 28/01/2025

No, not by themselves. I think you still need reselect, or something like it

Louis DeScioli @lou.descioli.com · 27/01/2025

I’m so skeptical that the compiler will be just as performant for the case of multiple selectors composed together with specific caching strategies. I think we’ll still need useContextSelector for quite some time 🤷‍♂️

110

Louis DeScioli @lou.descioli.com · 27/01/2025

Is the benefit of this over use-context-selector that use+useMemo will hopefully just be simple renames to the APIs from react when the memo+context optimization is eventually implemented? vs useContextSelector, which won't ever be part of the core React API?

Hm, ok. So when adding a dependency to a project, you would still only add it to the root package.json, or you’d have to root and the project’s?

100

Louis DeScioli @lou.descioli.com · 17/01/2025

Does using workspaces imply a multiple package.json/multi-version setup?

100

Louis DeScioli @lou.descioli.com · 16/01/2025

I'm having a bit of trouble following the latest best practice with Nx. If I have a traditional one-version Nx monorepo, with a single root package.json and a tsconfig.json & project.json for each lib & app, is that still optimal or is there a better way to do this now?
