Report #103446

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

Add a 'paths' mapping with a wildcard pattern under 'compilerOptions' in the consuming package's tsconfig.json \(e.g. "@org/\*": \["../packages/\*/src"\]\) and ensure 'baseUrl' is set or the paths values are relative to it. If using TypeScript 4.7\+ with native ESM, prefer 'moduleResolution': 'NodeNext' or 'bundler' so path mapping is honored alongside Node.js resolution semantics.

Journey Context:
In a pnpm workspace, a package imported '@org/utils' and the app compiled fine in the IDE, but 'tsc' threw TS2307. I ran 'tsc --traceResolution' and saw TypeScript never tried the monorepo package directory; it only looked in 'node\_modules/@org/utils'. The tsconfig had 'paths' defined at the repo root, but the app package's own tsconfig extended it and accidentally overrode 'baseUrl' to '.', which made the relative path values in 'paths' resolve from the wrong directory. After fixing 'baseUrl' and adding the '\*' wildcard so '@org/utils' matched '../packages/\*/src', resolution worked. The wildcard matters because TypeScript matches the whole import specifier against the pattern; without it, only exact imports resolve.
