The monorepo documention (https://docs.railway.com/guides/monorepo) describes two kinds of monorepos but there's a third kind, a monorepo that looks like this (a monorepo that uses yarn workspaces):
|--- package.json
|------ backend
|---------package.json
|------frontend
|---------package.json
Here, frontend has a dependency on backend through the root level package.json which looks like
{
"private": true,
"workspaces": [
"frontend",
"backend"
],
"packageManager": "yarn@4.5.3"
}I can't set the respective folders as root in either service because then Docker can't find yarn.lock (which only exists at the top level with yarn workspaces) and I can't get the shared approach to work either because each package has their own package.json with their own set of build commands.

what do you mean 3rd kind?
I finally got it to work, or at least farther than where I was but I had to modify relative paths in my Dockerfile to do so which I'm not particularly pleased about
Similar to how you can set RAILWAYDOCKERFILEPATH to point to your dockerfile, is there a way to point to your nixpacks.toml?

yep! - NIXPACKS_CONFIG_FILE

let me know if theres any more questions!
and got the frontend app to work! Here was my resulting nixpacks.toml:
# https://nixpacks.com/docs/configuration/file
# set up some variables to minimize annoyance
[variables]
NPM_CONFIG_UPDATE_NOTIFIER = 'false' # the update notification is relatively useless in a production environment
NPM_CONFIG_FUND = 'false' # the fund notification is also pretty useless in a production environment
NODE_ENV = 'production'
[phases.setup]
nixPkgs = ['nodejs', 'yarn']
cmds = [
'corepack enable'
]
[phases.install]
cmds = [
'cp ./yarn.lock frontend',
'yarn install --immutable'
]
[phases.build]
cmds = [
'rm frontend/yarn.lock',
'yarn build:backend',
'yarn build:frontend'
]
# download caddy from nix
[phases.caddy]
dependsOn = ['setup'] # make sure this phase runs after the default 'setup' phase
nixpkgsArchive = 'ba913eda2df8eb72147259189d55932012df6301' # Caddy v2.8.4 - https://github.com/NixOS/nixpkgs/commit/ba913eda2df8eb72147259189d55932012df6301
nixPkgs = ['caddy'] # install caddy as a nix package
# format the Caddyfile with fmt
[phases.fmt]
dependsOn = ['caddy'] # make sure this phase runs after the 'caddy' phase so that we know we have caddy downloaded
cmds = ['caddy fmt --overwrite frontend/Caddyfile'] # format the Caddyfile to fix any formatting inconsistencies
# start the caddy web server
[start]
cmd = 'exec caddy run --config frontend/Caddyfile --adapter caddyfile 2>&1' # start caddy using the Caddyfile config and caddyfile adapterit was…a lot. Would be great if railway supported yarn workspaces out of the box better because that was pretty rough
