Report #13084

[bug\_fix] Cannot find module '@/utils' or its corresponding type declarations. ts\(2307\)

Add 'baseUrl': '.' \(or 'src'\) to compilerOptions in tsconfig.json, ensuring 'paths' mappings are relative to that baseUrl. The compiler needs baseUrl to resolve the asterisks in paths correctly.

Journey Context:
You refactor a Node project to use path aliases, creating a tsconfig.json with compilerOptions.paths set to \{'@/\*': \['src/\*'\]\}. Your IDE autocomplete works, but tsc throws TS2307 on every alias import. You verify the files exist at src/utils.ts. You try restarting the IDE. You search and find that paths resolution requires a baseUrl anchor. You add 'baseUrl': '.' and the errors vanish because the compiler now resolves '@/\*' relative to the project root.

environment: Node.js project with TypeScript 4.x or 5.x, path mapping configured without baseUrl, using ES modules or CommonJS. · tags: ts2307 path-mapping baseurl module-resolution tsconfig · source: swarm · provenance: https://www.typescriptlang.org/tsconfig\#paths
