can't build Preact X + Typescript

See original GitHub issue

hi everybody, I wanted to play a little bit with Preact X before official release, but I’m finding stuck with basic building of a Typescript template project.

steps to reproduce:

$ npm i -g preact-cli@next
$ preact create typescript x-test
$ cd x-test
$ npm i -D preact-cli@next @types/react
$ npm i preact@next preact-router@next
$ npm run build

and I get the following errors (at 95% of build 😭):

✖ ERROR ./node_modules/preact-router/index.d.ts
ERROR in ./node_modules/preact-router/index.d.ts(65,62):
TS2694: Namespace 'global.JSX' has no exported member 'HTMLAttributes'.
✖ ERROR ./node_modules/preact-router/match.d.ts

✖ ERROR undefined

running npm start is fine, the project is built and can be opened in the browser, is only the build command that it’s breaking.

I’ve figured out reading other issues how to “upgrade” to Preact X, I didn’t found any documentation or note about it in repo or website, so maybe I’m missing something.

Any feedback is appreciated, thanks
