Export Typeinformation for Libraries

Kadrei opened this issue · comments

To get the most out of using flowtypes it would be amazing if sagui automatically exports the type information when building (build/dist).

As far as I understand flow automatically uses types in dependencies with the .flow - file-extension.

Imo a good approach would be to do a normal build to generate a typeless file for use and also generate the same file(s) with the type information and the file extension .flow.

This is extremely useful when building Libraries for use in other Projects as they can now fully use the type information of the library.

At least if we can trust https://javascriptplayground.com/blog/2017/01/npm-flowjs-javascript/

Another solution could be to use https://babeljs.io/docs/plugins/transform-flow-comments/

But I think this will result in an increase of filesize and would also require us to bundle external defined flowfiles in the distribution.
