Habitat multisite solution structure example

Question

I've created my own helix based solution on the habitat project and I need to support multiple sites in this solution. But I don't know how to structure the Project folder here I need to create is the following basic structure the right approach or did I miss something?

• Project
  • Common
  • DotComWeb
  • DotComCommon
  • ShopsWeb
  • ShopsCommon

Answer 1

When I was setting up our project layer based upon the Helix architecture principles for the project layer, this bit stood out to me:

Typically, in a single tenant solution there will only be a single module, namely the specific website or requirements that fits the needs of the tenant, and this will contain little or no pre-compiled code but instead consist of mark-up, styling, layout and templates of the item types in Sitecore which the editors can create (see Template types).

And for Habitat:

"The Common module paves the way for a multi-tenant implementation by defining some of the shared templates and settings between tenants."

So our current structure looks very similar:

• Project
  • AbcWebsite
  • Common
  • QrsWebsite
  • XyzWebsite

What I'm not sure is what the use case would be for another Common project for each website, as you've done.

Unless you have multiple multi-tenant implementations with their own shared code, I wouldn't expect you'd need another common project for each website. And if you do have multi-tenant implementations like that (such as if each multi-tenant instance is a different client/customer), I wonder if that should instead be a different Visual Studio solution, one for each client/multi-tenant instance.

This also means that if you don't have a multi-tenant solution, a Common project layer module wouldn't be required.
