Proposed fix: [TypeScript 6.0] Deprecation errors TS5101/TS5107 'Option 'baseUrl' is deprecated and will stop functioning in TypeScript 7.0' (also moduleResolution node/node10, target es5, outFile, mo
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Migrate: remove baseUrl and prefix each paths entry (e.g. "@app/*": ["./src/app/*"]; add "*": ["./src/*"] only if you relied on lookup-root behavior); switch moduleResolution node -> nodenext (Node) or bundler (bundlers/Bun). Use the experimental ts5to6 codemod for baseUrl/rootDir.
Option: Rewrite paths without baseUrl and modernize moduleResolution [evidence: official_recommended_action]
Applies when: Projects upgrading to TS 6/7
Steps:
1. Delete baseUrl; prefix paths values with ./src/...
2. Set moduleResolution to nodenext (Node) or bundler
3. Run tsc; optionally try the ts5to6 codemod
Expected: No deprecation errors; config ready for TS 7
