@onetapaway/eslint-config-ota v2.0.2

eslint-config-ota

Shareable eslint config for OTA Node projects using recommended eslint/prettier configs.

Getting Started

You can install this package directly from gitlab npm i --save-dev @onetapaway/eslint-config-ota

Next the peer dependencies will need to be installed manually npm i --save-dev eslint eslint-config-prettier eslint-plugin-prettier prettier eslint-plugin-jest

Inside your node project's package.json file add the following eslintConfig:

  "eslintConfig": {
    "extends": "eslint-config-ota"
  }

OTA configuration rules can be overridden on a per project basis by adding a rules object to the eslintConfig object in the project's package.json file.

  "eslintConfig": {
    "extends": "eslint-config-ota",
    "rules": {
      "no-unused-vars": "warn"
    }
  }

The above will set eslint's no-unused-vars rule to the level of warning instead of it's default of error

Usage

Run eslint and prettier in a single command: npx eslint "*.js"

To automatically fix problems: npx eslint "*.js" --fix

See complete list of options available

For ease of running consider adding a lint command to your package.json:

"scripts": {
  "lint": "eslint \"**/*.js\""
}

Setting up precommit hooks (optional)

We can setup precommit hooks in our projects to automatically run and fix any violations before a file is committed to git.

Install husky and lint-staged to your project npm i --save-dev husky lint-staged

Add the following configuration to your project's package.json

  "husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  },
  "lint-staged": {
    "*.js": [
      "npx eslint --fix",
      "git add"
    ]
  }

Now upon running git commit a pre-commit hook will run the eslint command for you. Any violations that aren't automatically fixed will need to be fixed by hand before committing your code.
