npm - Multiple entrypoints in typescript external modules not resolved -

i trying build external module, @example/lib typescript multiple entry points. consume this:

import * lib '@example/lib'; import * foobar '@example/lib/foobar'; 

i can build npm module works correctly setting "target": "es5" , "declaration": true in tsconfig, , pointing "main" , "typings" properties in package.json single source location. if this, can import @example/lib without issue.

the problem arises when attempt import @example/lib/foobar. typescript complains "cannot find module @example/lib/foobar". compiled output, can import submodule fine (after being processed webpack).

inside @example/lib project have source files:

index.js index.d.ts foobar.js foobar.d.ts 

and in package.json have:

{     ...     "typings": "index.d.ts"     "main": "index.js"     ... } 

what need keep typescript happy (and type checking!) in case?

the above does, in fact work.

unfortunately in case d.ts file not being generated foobar, (though source was, due error).
