Hello hello!
I have a small CRUD project with with two separate mix files (applications) for separation of concerns.
Blog_App
--- browser(Phoenix Liveview Front End)
--- blog (All of the CRUD business logic and DB)
The blog has a functioning Blog.Repo, but I don’t quite understand how to start/find this repo when starting mix phx.server in Blog_App/browser.
My error-
could not lookup Ecto repo Blog.Repo because it was not started or it does not exist
I’ve tried-
in Browser’s mix.exs setting the deps
{:blog, path: "../blog"}
and
setting Blog.Repo as one of the children to start in browser’s application.ex.
Any ideas or tips?
Thanks for any help 
You also need to configure Blog.Repo in Browser…
Phoenix does already this separation of concern, with App, AppWeb.
It’s meant to separate Core Business Logic, and Web interface.
I am also curious how You build your Blog part. Is it a simple mix new project --sup?

Ha yes, I’m just trying to separate the concerns even further 
Correct, Blog has it’s own Supervisor tree already implemented from the boiler plate mix new project --sup command
It’s possible and I do it very often…
But Blog’s config needs to be duplicated in the Browser’s config.

Ah! That makes sense to edit in the config file. The error is gone now. I just added it like this-
browser/config.exs
config :browser,
ecto_repos: [Browser.Repo]
config :blog, Blog.Repo,
database: "blog_repo",
username: "postgres",
password: "pass",
hostname: "localhost"
config :blog,
ecto_repos: [Blog.Repo]
Just copied and pasted the config from blog/config.exs. That’s what you’re talking about, right?
