Support typescript natively

[ziimakc]

Allow to run typescript files natively.

The flag --experimental-strip-types enables Node.js to run TypeScript files. https://nodejs.org/api/typescript.html

Flag is available in current LTS node v22.

Hey @ziimakc,

Hmm... This should work:

"test:smoke:strip-types": "node --experimental-strip-types test/smoke/ts.test.ts",

What's your use case?

[antongolub]

Anyway, it seems reasonable provide overriding the default ext (.mjs) in some cases.

It will be cool if zx have support for ts without any other:

npx zx script.ts

zx can spawn a node with --experimental-strip-types on it's own.

[antongolub]

npx accepts node flags via NODE_OPTIONS for its own internal spawn: NODE_OPTIONS='--experimental-strip-types' npx zx. So we can avoid extra node > node process init.

@antongolub I just want to run typescript files to ensure scripts are correct.

[antongolub]

In this case tsc is required to check (not only strip) types.

[ziimakc]

@antongolub yes, tsc to check types and --experimental-strip-types to run the file

"test:smoke:strip-types": "node --experimental-strip-types test/smoke/ts.test.ts"

Indeed, I was confused a bit because of zx explicit imports are required then.
