I wonder whether there is a web-shop or another custom web-app available which could be used for own projects. Best would be if this app already supports self-registration with e-mail verification, passwort-reset and self-managing of “own Party” data.
Well, we are still maintaining nereid_webshop which consists of a fully integrated suite over nereid, a flask integration over trytond. It is still at version 6.0, migration to 7.0 is underway.
