Auto-import not using up TypeScript path alias when using barrel export (index.ts)

[dd-jonas]

Type: Bug

tsconfig.ts:

{
  "compilerOptions": {
    "allowJs": false,
    "allowSyntheticDefaultImports": true,
    "baseUrl": "./src",
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "isolatedModules": true,
    "jsx": "react-jsx",
    "lib": ["dom", "dom.iterable", "esnext"],
    "module": "esnext",
    "moduleResolution": "node",
    "noEmit": true,
    "noFallthroughCasesInSwitch": true,
    "outDir": "dist",
    "paths": {
      "~/api": ["api/index.ts"],
      "~/assets/*": ["assets/*"],
      "~/components": ["components/index.ts"],
      "~/constants/*": ["constants/*"],
      "~/hooks": ["hooks/index.ts"],
      "~/pages/*": ["pages/*"],
      "~/router": ["router/index.tsx"],
      "~/schemas": ["schemas/index.ts"],
      "~/store": ["store/index.ts"],
      "~/store/*": ["store/*"],
      "~/styles/*": ["styles/*"],
      "~/translations/*": ["translations/*"],
      "~/types": ["types/index.ts"],
      "~/utils": ["utils/index.ts"]
    },
    "resolveJsonModule": true,
    "skipLibCheck": true,
    "strict": true,
    "target": "ESNEXT"
  }
}

1. When I type useModal, I get the import suggestion hooks/useModal. I would expect the suggestion ~/hooks instead, as this function is exported from hooks/index.ts as specified in my tsconfig file.
2. When I type EMAIL, I get the expected import suggestion ~/constants/regex. The difference in behavior seems to be caused by using barrel export files (re-exporting all submodules in index.ts).

The exports in all index.ts files are specified as e.g. export * from './useModal'. It seems to make no difference when I change it to export { useModal } from './useModal'. I have also tried enabling "typescript.preferences.importModuleSpecifier": "non-relative" which makes no difference.
Disabling all extensions has no effect.

Is there a way to solve this problem? It's annoying currently to always update the import manually.

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.82.2. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

We'd need a demo repo to understand what's going on here. There are many variables at play when determining auto-import priority

Hi @RyanCavanaugh, I made a reproduction here: https://github.com/dd-jonas/tsconfig-path-alias-autocomplete. While making this reproduction, I noticed the '/' in the path alias is the culprit (e.g. "~/api" does not work but "~api" does). Is this a bug or expected behavior?

[RyanCavanaugh]

Confirmed we're not using withIndex even with import preference set to non-relative and removing baseUrl from the tsconfig

Hey! Did this get into typescript 5.4 by chance?
