How do I get lint-staged working with Husky version 6

Question

I try to use Husky's pre-commit and lint-staged.

Those are installed:

"husky": "^5.1.3",
"lint-staged": "^10.5.4",

In package.json I have:

"scripts": {
    "build": "gatsby build",
    "develop": "gatsby develop",
    "format": "prettier --write \"**/*.{js,jsx,ts,tsx,json,md}\"",
    "start": "npm run develop",
    "serve": "gatsby serve",
    "clean": "gatsby clean",
    "test": "echo \"Write tests! -> https://gatsby.dev/unit-testing\" && exit 1",
    "lint": "eslint --ext .js,.jsx,.ts,.tsx src --color",
    "isready": "npm run format && npm run lint && npm run build"
  },
  "husky": {
    "hooks": {
      "pre-commit": "lint-staged",
      "pre-push": "npm test",
    }
  },
  "lint-staged": {
    "./src/*.{js,jsx,ts,tsx}": [
      "npm run format",
      "npm run lint",
      "git add"
    ]
  },

If I run npm run lint, currently I have 2 problems (1 error, 1 warning). So when I run git commit, I don't expect to be able to commit, right? But I can proceed and finish the commit.

What's wrong?

Update:

I downgraded husky to 4.3.8:

"husky": "^4.3.8",
"lint-staged": "^10.5.4",

Inside package.json, in my scripts I have:

"prettier": "prettier '**/*.{js,jsx,ts,tsx}' --write",
"lint": "eslint --ext .js,.jsx,.ts,.tsx src --color",

And:

"husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  },
  "lint-staged": {
    "src/**/*.{ts,tsx,js,jsx}": [
      "npm run prettier",
      "npm run lint",
      "git add"
    ]
  },

When I do a commit, Husky is still not fired off. What's wrong?

Update 2: I couldn't get Husky 4 to work so I upgraded to version 6:

npm install husky@6 --save-dev \
  && npx husky-init \
  && npm exec -- github:typicode/husky-4-to-6 --remove-v4-config

Now it works fine.

The only thing I can't get to work is lint-staged.

• I added the hook npx husky add .husky/pre-commit "lint-staged"

But then I get .husky/pre-commit: line 4: lint-staged: command not found? How do I get lint-staged working with Husky version 6?

Answer 1

Making lint-staged working with Husky version 6 by adding:

// .husky/pre-commit
npm run pre-commit

and:

// package.json
{
  "scripts": {
    "pre-commit": "lint-staged"
  }
}

Answer 2

Based on this husky github issue, just do these steps to make it work(we did it and it is working fine):

1. npx husky-init
2. yarn
3. npx husky add .husky/commit-msg 'npx --no-install commitlint --edit "$1"'
4. yarn add @commitlint/config-conventional @commitlint/cli --dev

.commitlintrc.json:

{
  "extends": ["@commitlint/config-conventional"]
}

.lintstagedrc:

{
  "src/**/*.+(js|json|ts|tsx)": [
    "eslint"
  ],
  "src/**/*.{js,jsx,ts,tsx,json,css,scss,md}": [
    "prettier --write"
  ]
}

.husky/pre-commit:

#!/bin/sh
. "$(dirname "$0")/_/husky.sh"

yarn pre-commit-lint

Finally, add pre-commit-lint script to package.json:
