I plan for Vue language tools v4 to be agnostic to the Vue Content Mapper package, so users will be able to replace @vue/content-mapper with Vize themselves.

create-vue 3.24.0 adds a tsgo option, letting you replace TypeScript with typescript-native-bridge.
The version also clarifies that the overwrite prompt deletes all existing files. "fix: keep Ox" is where the Oxlint side of the changelog stops in what we can see.
CI got less chatty too. The playground submodule now carries a private root package․json so pnpm 12 can verify dependencies without reinstalling and writing install progress to stderr during the Vitest job.
create-vue-templates added a root manifest for pnpm dependency checks and holds a 3.24.0 version snapshot. Meanwhile the lock files got refreshed. #vuejs

I wrote and solely maintain rolldown-plugin-dts. An @AnthropicAI engineer contributed two PRs using Claude Code.
Meanwhile, Anthropic suddenly suspended my own Claude account—the tool I use to maintain that same project. The irony is hard to miss.

The crazy part is that replacing magic-string with muggle-string noticeably improved the Vue compiler’s performance, memory use, and source map accuracy.

I've sent a skill I put a lot of work into to every individual sponsor who has given over $200 in total, as a small thank-you. Check your email. 🎁

アクセシビリティかい！！！！！
それなら vize/compiler で templateSyntaxMode: "strict" にしつつ．
vize/linter で a11y のリントを有効にしまくって，
vize/musea でストーリーを書いて axe-core でテストすれば自然にいい感じのマークアップが高速に書けるよ！！！

Vue Language Tools v4 alpha is out.
TypeScript 7's own tsc now type-checks .vue files via @vue/content-mapper, no more vue-tsc.
* Editor support isn't ready yet.

That's what i thought, and is how things are set up rn for ts 7.1
I need to double check the html and css support tho (for ember), bucause i'm a little perplexed by vue still wanting volar!

If Ember still needs HTML (or CSS) support, it will most likely still need Volar.js. But I'm revisiting the framework design in Volar.js v3, so that even if you have to use it, things stay as simple as possible. For example, Volar.js and Content Mapper will share the same object shapes as much as possible.

was most of that 8.7k the typescript side, like the tsserver plugin and program proxy that mapped diagnostics back through the virtual code, so v3 only keeps source mapping for the html and css services?

Impressive. @vuejs + content mappers + tsrs are amazing!
Tested this on the @nuxt_js ui repo and can't wait to see the impact on big Vue projects 🔥
ALT Nuxt UI type-checking benchmark across 208 Vue files. Time: vue-tsc + TS6, 15.35 seconds; vue-tsc + TS7.1, 3.76 seconds, vue-tsc + tsrs, 2.08 seconds. Peak memory: 1,823 MiB, 1,751 MiB, and 991 MiB respectively. Lower is better for both metrics.

42s → 8s → 5s
Type-checking one of our Vue codebases (~1k files, ~200 SFCs):
vue-tsc + TS6 → TS 7.1 → tsrs --fast
TS 7.1 and tsrs run Vue through the new @vue/content-mapper alpha. I'm excited.

In language-tools v4, several modifiers edit the same code in an order no one can predict. muggle-string handles this in its API design: whichever of the 24 orders they run in, the output is the same.
