受TypeScript保护和npm软件包

Question

I'm currently building an internal TypeScript "library" with webpack 1.14.
To do so I created a npm package and published it to a private feed. Everything works like a charm (I can use classes and interfaces from the library in other "projects" installing the package).

The only thing I'm struggling with is protected members of classes in the library. When a class in a consuming project extends a class from the library it cannot use protected parent members . The confusing part is that auto completion "sees" the protected members but I get this error during compilation. error TS2339: Property 'apply' does not exist on type 'SitesRollup'

The typescript protected keyword documentation does not state that protected members are restricted to current module, so I'm assuming it should just work.

My question is: should protected members be visible in extending/inheriting classes from different modules?

Answer 1

Finally found where the issue was coming from. The overall type mapping wasn't working properly. This was because of two reasons:
First I was missing this line in the package.json file "types": "dist/src/index.d.ts", allowing tsc (and my editor) to properly locate the types of the library.
Second my library wasn't properly emitting the typings, fixed that adding "declaration": true, to my complierOptions in my tsconfig.json file.
Hope that helps.
