Run linter in a subdirectory

Our monorepo has two relatively separate projects in it, with their own Prettier config in project-A and project-B. I’m looking for a way to do something like this:

"lint-staged": {
    "project-A/**/*.js": [
      "cd project-A && prettier --check"
    ],
    "project-B/**/*.js": [
      "cd project-B && prettier --check"
    ],
}

(Prettier needs to have a working directory set to either project-A or project-B to pick up the right ignore & config files.)

This doesn’t work as it resolves to something like this:

  lint-staged:task bin: /usr/bin/cd +8ms
  lint-staged:task args: [ 'project-A',
  lint-staged:task   '&&',
  lint-staged:task   'yarn',
  lint-staged:task   'prettier',
  lint-staged:task   '--check',
  lint-staged:task   '/Users/borekb/example/project-A/index.js' ] +0ms

A workaround is to create npm scripts like this:

"scripts": {
  "prettier-A": "cd project-A && prettier --check",
  "prettier-B": "cd project-B && prettier --check"
},
"lint-staged": {
    "project-A/**/*.js": [ "yarn prettier-A" ],
    "project-B/**/*.js": [ "yarn prettier-B" ]
}

Is there a built-in way to run lint-staged in a subdirectory / subfolder?

(We’re using lint-staged@8.1.15.)

Another way of working around this is to use yarn workspaces. Then you can basically run:

"lint-staged": {
    "project-A/**/*.js": [ "yarn workspace @myorg/project-A prettier" ],
    "project-B/**/*.js": [ "yarn workspace @myorg/project-B prettier" ]
}

(Replying here since this thread pops up on web searches)
