typescript - Typings for sub-folders inside a root index.d.ts -

-



we created typings material-ui@next , want ship them library, did last beta.

here link index.d.ts.

but typings not usable in current form. in development used locally , worked fine, when shipping files library typescript seems use different discovery strategy.

all typings reference subfolder (e.g. declare 'material-ui/button/button') not found typescript. when importing components error show up:

[ts] not find declaration file module 'material-ui/button/button'. '<project path>/node_modules/material-ui/button/button.js' implicitly has 'any' type.   try `npm install @types/material-ui/button/button` if exists or add new declaration (.d.ts) file containing `declare module 'material-ui/button/button';`

does typescript not accept declaring other imports when used inside npm_modules folder? because said, using them locally or moving them @types/material-ui make them work.

also, typescript seems find index.d.ts, because importing "root" works (import { button} 'material-ui').

so, turns out typescript treats typings inside of node_modules/@types/* , node_modules/* different:

typings in @types called augmented modules. global , in them on project's code. why accessing submodule declarations, material-ui/button/button, work.

regular npm modules treated (regular) modules. thus, if import subfolder subfolder must contain typings. typescript not go root of modules , check if typings there have augmented modules.

this means (a) have publish typings definitelytyped or created .d.ts files every subfolder , file.
