Libraries outside of node_modules that are made available using paths-mapping are not currently processed by ngcc, so they are not compiled for Ivy usage. For the time being you can run ./node_modules/.bin/ivy-ngcc -s ./dist each time after building the library and before serving.

oic, any road map for this feature ?
./node_modules/.bin/ivy-ngcc -s ./dist <-- it work, but ... i can't do this all day ... /.\

@manughub could this be moved to @angular/angular-cli, as it is caused by how @ngtools/webpack processes modules.

I've moved this issue to the CLI repo. We don't yet have good support for Ivy libraries in the CLI.

Hi @keatkeat87, yes this is something in the roadmap to add ngcc processing on workspace libraries. We are targeting this for 8.1

Thanks
