require(esm) in Node.js: from experiment to stability
More than a year ago, I set out to revive require(esm) in Node.js and landed an experimental implementation. After a lot of iteration and battle-testing, require(esm) is now unflagged across all suppo

npm's broken UI bugged me enough I wrote a userscript to fix them, and added some features too. Repo: github.com/bluwy/npm-us...

I feel the dilemma is, that I feel responsible for being friendly and welcoming to make the experience nicer for newcomers to OSS, who may not yet know the manner well.
But with AI messing this up, it's really hard to tell if it's a human behind I should take care or just AI doing terrible work.

Vite bundled some dependencies for perf

Vite bundled some dependencies for perf
I think the package.json file should include a field `inlineDependencies` to record the dependencies of inline bundles and separately calculate their download size.

Hello friends and welcome to a new “How is ESM vs CJS going!” 33.4% of the popular packages on npm now includes ESM. Up from 29.6% half a year ago. We have a third!
ESM-only is up from 11.5% to 12.6%.
This is also the impact of half a year of Node 18 being EOL, making `require(esm)` available

Another issue I had: TS7 doesn't work well with Vue LSP (basically Volar.js).
Maybe Volar.js needs to work more closely with the TS team. For now, is there a way in tsconfig (or something else) to choose between TS5 + Volar.js and TS7 only?

Only one case, and I assume it’s due to an issue with my code.
TS 5 didn’t emit it, but TS 7 did.

Three years ago, frustrated with performance, I offhandedly said, “Wait until TS gets rewritten.”
Today, it finally happened.

The new version will enable `failOnWarn` by default in CI environments to ensure strict build quality.
You can also choose to run publint and arethetypeswrong only in CI, speeding up your local builds!

It's common to need different settings for different formats.
Now, you can share a base config and specify separate options for CJS and ESM formats, all within a single config options.

The build API and hooks now return the built chunk content directly.
With the write option, you can access the output without writing to disk.

Previously, tsdown used chokidar to watch for file changes and then rebuilt with rolldown.
Now, it leverages rolldown’s built-in watch API, making it faster and cutting out an extra dependency.
