Remove ignoreDeprecations workaround once tsup supports TypeScript 6 #57
Description
Context
TypeScript 6.0 deprecated the baseUrl compiler option (TS 6 migration). tsup's DTS build internally sets baseUrl, causing build failures:
error TS5101: Option 'baseUrl' is deprecated and will stop functioning in TypeScript 7.0.
Current workaround
We added "ignoreDeprecations": "6.0" to tsconfig.json to silence this.
Upstream tracking
- DTS Build error TS5101: Option 'baseUrl' is deprecated and will stop functioning in TypeScript 7.0. egoist/tsup#1388 — DTS build error report
- Support TypeScript 6 egoist/tsup#1389 — TypeScript 6 support request
Action
Once tsup ships a fix (removing its internal baseUrl usage), remove "ignoreDeprecations": "6.0" from tsconfig.json.
