Syncing TSConfig Paths

Keep tsconfig paths in sync with package.json subpath imports.

Steps

Syncing

pnpm exec tsx .claude/skills/syncing-tsconfig-paths/scripts/sync-tsconfig-paths.ts

Auditing

Run with --check flag to verify without modifying:

pnpm exec tsx .claude/skills/syncing-tsconfig-paths/scripts/sync-tsconfig-paths.ts --check

Reference

The script transforms package.json imports to tsconfig paths:

// package.json
{
  "imports": {
    "#pkg": "./build/_.js",
    "#foo": "./build/foo.js"
  }
}

Becomes:

// tsconfig.json
{
  "compilerOptions": {
    "paths": {
      "#pkg": ["./src/_.ts"],
      "#foo": ["./src/foo.ts"]
    }
  }
}

Key transformation: ./build/ → ./src/ (extension stays .js - TypeScript with nodenext resolves to .ts)

Notes

• Run after modifying any package's imports field
• Conditional imports (objects with browser/default) are skipped with a warning
• This enables TypeScript to resolve # imports during development before build
