Error: fatal: Not a git repository

When trying to use lint-staged and husky in a project where the actual node.js project is a child directory of the git repo (as shown below):

project
  └─ node-app
       └─ package.json

I get the following error:

:; git commit                                                                                                                  

> husky - npm run -s precommit

When running npm run precommit, I see a lot of these errors

:; npm run precommit

That’s why I encourage people to read the README when something isn’t working 😃

@maxime1992 You have to insert gitDir as property of lint-staged. like this.

{
  "lint-staged": {
    "gitDir": "../",
    "*.ts": [
      "yarn run prettier:precommit",
      "git add"
    ]
  },
  ...
}
