Hey @codemaniac,
I am also struggling to find the way how Strapi wants us plugin-developers to create (and bring along) components with our plugin.
Without that created content-Types are quite dumb.
I know @Boegie19 is a busy man but maybe you know how it’s possible to create a plugin with some plugin-related components.
Or are there any (near) future plans to improve creating plugin in the direction of components?
Because refactor(core/strapi): move components to registry by iamandrewluca · Pull Request #16273 · strapi/strapi · GitHub does sadly not sound like that so we might have to wait until v5?
