Found interesting behavior regarding apps directory, which I’m not reporting as a bug because I don’t think it’s workspace’s issue; but noting here for people who are figuring out their own monorepo directory structure.
I was playing around with the directory structure where I created a blank workspace, then a “domains” path for domain bounded context applications.
mix workspace.new my_workspace
cd my_workspace
mix deps.get && mix compile
mkdir domains
cd domains
mix new --sup mytestdomain1
mix phx.new mytestdomain2
cd ..
mkdir apps
cd domains
mix phx.new mytestdomain3
mix new --sup mytestdomain4
The workspace before mkdir apps
my_workspace % ls
README.md _build deps domains mix.exs workspace.lock
The workspace after apps and mix creating the new phoenix project
my_workspace % ls
README.md apps deps mix.exs workspace.lock
_build config domains mix.lock
Highlighting:
That the mytestdomain2 project config is within the mytestdomain2 path; but after just making the apps directory, mytestdomain3 has config references (in its mix.exs) pointing to a top level config path.
Expansion of details:
mytestdomain2 % ls
README.md assets deps mix.exs priv
_build config lib mix.lock test
mytestdomain2 % cat mix.exs
defmodule Mytestdomain2.MixProject do
use Mix.Project
def project do
[
app: :mytestdomain2,
version: "0.1.0",
elixir: "~> 1.14",
elixirc_paths: elixirc_paths(Mix.env()),
start_permanent: Mix.env() == :prod,
aliases: aliases(),
deps: deps()
]
end
... OMITTED ...
and
mytestdomain3 % ls
README.md assets lib mix.exs priv test
mytestdomain3 % cat mix.exs
defmodule Mytestdomain3.MixProject do
use Mix.Project
def project do
[
app: :mytestdomain3,
version: "0.1.0",
build_path: "../../_build",
config_path: "../../config/config.exs",
deps_path: "../../deps",
lockfile: "../../mix.lock",
elixir: "~> 1.14",
elixirc_paths: elixirc_paths(Mix.env()),
start_permanent: Mix.env() == :prod,
aliases: aliases(),
deps: deps()
]
end
... OMITTED ...
Concluding:
The phoenix project generator switches logic to generate an umbrella based phoenix project if it detects the existence of a top-level (in monorepo) apps directory.
Which stands to reason is because the apps path is significant to elixir umbrella projects.
Regular mix new projects don’t have configs so they look as expected.
