Need some pointers to build a local version of docx-templates for browser.

[brijeshbv]

Hello,
I am currently working on a patch version of docx-templates for some custom modifications.

I am able to build and publish my patch to a private npm repository.
The library works fine when I use it in a node environment, however I seem to have not built the binaries right for the browser version.

The same patch version on the browser throws the following error when I import the library as shown here:
import createReport from 'docx-templates';

Error when pointing to the locally built library:
Error in v-on handler (Promise/async): "SyntaxError: The requested module '/xxxxxxxxxxxxxxx/repos/docx-templates-original/lib/index.js' does not provide an export named 'default'"

Can I please be pointed to the build and publish documentation used for the official release ?
Any help here would be much appreciated.
