Next.js Type error: Could not find a declaration file for module `@scalar/openapi-parser`

[huypham50]

What happens?

Type error: Could not find a declaration file for module '@scalar/openapi-parser'. '/Users/johndoe/Desktop/repo/node_modules/@scalar/openapi-parser/dist/src/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/scalar__openapi-parser` if it exists or add a new declaration (.d.ts) file containing `declare module '@scalar/openapi-parser';`

> 1 | import { dereference } from "@scalar/openapi-parser";

What did you expect to happen?

Should have no type errors since package is written in Typescript (which is great!)

How can we reproduce the issue?

yarn add @scalar/openapi-parser

What! Do you have the latest version? 0.7.1?

Latest version should have "types": "./dist/index.d.ts" not "types": "./dist/src/index.d.ts"

Anyway, I’m about to update the build process this week, I’ll make sure to fix this swiftly if it’s still in the latest version.

[huypham50]

Yep latest version 0.7.1 and the .d.ts is in the wrong place.

If I import { dereference } from "@scalar/openapi-parser/dist/src"; then the type errors go away but there's a compile error instead

Module not found: Package path ./dist/src is not exported from package /Users/johndoe/Desktop/code/repo/node_modules/@scalar/openapi-parser (see exports field in /Users/johndoe/Desktop/code/repo/node_modules/@scalar/openapi-parser/package.json)

[hanspagel]

Oh man, I’ll fix that. Thanks for the great bug report!

[hanspagel]

It’s more than just fixing the pass. Some type definition files land in random places. But #127 fixes it.

[huypham50]

Thanks, I will test once change is live!

[hanspagel]

Fixed already. ✌️
