📝 Summary

• IDE shows deprecation warning for baseUrl option in jsconfig.json
• The jsconfig.json schema is validated against TypeScript compiler options

💡 Why this bug?

• Warning message appears in IDE:

Option 'baseUrl' is deprecated and will stop functioning in TypeScript 7.0.
Specify compilerOption '"ignoreDeprecations": "6.0"' to silence this error.

• baseUrl was originally designed for AMD module loaders in the browser, a use case that is no longer relevant
• Since TypeScript 4.1, paths works without baseUrl as long as paths use relative prefixes (e.g., "./*")
• TypeScript 7.0 is being rewritten in Go and will not reimplement baseUrl

Timeline

Version	Status
TypeScript 5.x/6.x	baseUrl works but shows deprecation warning
TypeScript 7.0	baseUrl will be removed

✅ Expected behavior

• IDE shows no deprecation warnings
• Remove baseUrl option since it is no longer required when using paths
• The current paths already use relative prefixes ("./*") so they work without baseUrl

📋 Steps

Phase 1: Remove deprecated option

• Remove "baseUrl": "." from compilerOptions in jsconfig.json:

 {
   "compilerOptions": {
-    "baseUrl": ".",
     "paths": {
       "~/*": ["./*"],
       "@/*": ["./*"],
       "~~/*": ["./*"],
       "@@/*": ["./*"]
     }
   }
 }

🧪 Tests

• IDE shows no deprecation warnings
• Path aliases still work correctly
