We needed to use this PR so we published an npm package called 'ngx-breadcrumbs-ui'. If you are using ngx-breadcrumbs with angular six you can swap the npm dependencies and fix your app with this work-around.

Hi @peterbsmith2. Thanks for your workaround. I tried to put your npm module working and everything work fine in dev enviroment. But running ng build --prod, an error was happens.

ERROR in ./node_modules/ngx-breadcrumbs-ui/ngx-breadcrumbs.ngfactory.js
Module not found: Error: Can't resolve 'ngx-breadcrumbs' in '[...]/node_modules/ngx-breadcrumbs-ui'

I tried to change "importAs":"ngx-breadcrumbs" to "importAs":"ngx-breadcrumbs-ui" in ngx-breadcrumbs.metadata.json and everything is working but i dont know if it is enough or if there are any other solution.

Thanks by advanced

@jpargana we incorporated your suggestion so the latest ngx-breadcrumbs-ui (0.0.10) ought to work fine.
