[bug]: TypeScript Export Path Issue with Strapi Plugin Build

[deivydarwoft]

What version of @strapi/sdk-plugin are you using?

• Npm version: 10.8.2
• Node.js version: 20.18.3
• React version: 18.3.1
• Strapi version: 5.23.3
• @strapi/sdk-plugin version: 5.3.2
• Browser: Chrome

What's Wrong?

When building a Strapi plugin with TypeScript, the generated type definitions (.d.ts) are placed in a nested folder (e.g. dist/<plugin-name>/admin/src/index.d.ts).

However, the default package.json configuration expects the types in dist/admin/src/index.d.ts and dist/server/src/index.d.ts, causing verification errors when running the script:

"verify": "strapi-plugin verify"

The error output:

[ERROR]  Missing files for exports:
    ./dist/admin/src/index.d.ts
    ./dist/server/src/index.d.ts

To Reproduce

1. Create or update a Strapi plugin with TypeScript in a monorepo (Nx or similar).

2. Use the default build scripts and tsconfig.build.json.

3. Run the build and verify commands:

   npm run build
   npm run verify

4. Observe that the type files are generated in dist/<plugin-name>/admin/src and dist/<plugin-name>/server/src.

5. The verification fails due to missing files in the expected export paths.

Expected Behaviour

• The plugin build should generate type files in the exact paths expected by the package.json exports field, or the package.json should be updated to match the actual output structure.

• After updating the package.json to:

  "types": "./dist/<plugin-name>/admin/src/index.d.ts"

  and

  "types": "./dist/<plugin-name>/server/src/index.d.ts"

  the verification passes and the plugin works as expected

Additional Notes

• If you run watch: strapi-plugin watch before running verify, the verification will pass without errors. This is because the watch command generates the type files in the expected locations before verification.
