Upgrading to Typescript 5.x

[egekorkan]

Should we update to version 5 (or newer) of TypeScript? We have noticed this in test-things due to discrepancy in the versions (not a huge deal) and I wasn't sure if there is a blocker.

I could not find an exact issue and asked @danielpeintner and we both remember something but not an issue it seems.

Some questions/aspects

• why are we pinpointing the version to a fixed version "typescript": "4.7.4" in the first place?
• out of curiosity I tried to update to [email protected] and npm run build fails with errors (e.g., node_modules/@types/node/globals.d.ts:73:13 - error TS2403: Subsequent variable declarations must have the same type. Variable 'AbortSignal' must be of typ)
  • Hence, I updated @types/node also which leads to even more issues with eventsource etc etc ... so it seems this requires more work :-(

I think it might have some consequences with #1267 too.
