Typescript <5 support?

[nikita-fuchs]

Hello, is there a Typia version that has the essential features working (type checks in runtime) but relying on a TS version < 5? I have an angular project that has this dependency. Couldn't find anything myself unfortunately.

Possible in NodeJS with latest version or typia with at TS 4.8 over version. It needs older version of ts-patch or ttypescript.

However, I do not know how it works on the Angular.

If not possible, consider generation mode.

Hey, thank you for the fast response ! I would really like to use and support this package !
I use "typescript": "4.8.4", with my Angular project. But after running npx typia setup I have "typescript": "5.6.3". The console output says

> ts-patch install && typia patch

[+] ts-patch installed!

Since TypeScript v5.3 update, "tsc" no more parses JSDoc comments.

Therefore, "typia" revives the JSDoc parsing feature by patching "tsc".
This is a temporary feature of "typia", and it would be removed when "ts-patch" being updated.

So it looks like Typia is installing TS 5?
How can I keep it at Typescript 4.8 ?

Install manually please

How would I install manually?

When I run `npx typia setup" it automatically installs and patches typescript version 5. How can I keep my typescript and make the setup patch my version 4.8.4 ?
