eslint-config-byurhan v0.0.6

eslint-config-byurhan

Personal ESLint/Prettier config plugin for my projects with my preferred code style

What it does

• Lints JavaScript based on the latest standards
• Fixes issues and formatting errors with Prettier
• Lints + Fixes React via eslint-config-airbnb
• You can see all the rules here. You can always overwrite any of these settings or just fork the entire repo to create your own config.

Install

1. If you do not already have package.json file, create one with npm init.

2. Then we need to install the plugin:

npm install --save-dev eslint-config-byurhan

3. Create a .eslintrc file in the root of your project folder. Your .eslintrc file should look like this:

{
  "extends": [
    "byurhan"
  ],
}

4. Now you can add the scripts to your package.json to lint and fix:

"scripts" {
  "lint": "eslint .",
  "lint:fix": "eslint . --fix"
}

5. Now you can run npm run lint to lint your code and npm run lint:fix to fix all fixable issues.

Settings/Rules

If you'd like to overwrite eslint or prettier settings, you can add the rules in your .eslintrc file. The ESLint rules go directly under "rules" while prettier options go under "prettier/prettier". Prettier rules overwrite anything in my config (trailing comma, and single quote), so you'll need to include those as well.

{
  "extends": [
    "byurhan"
  ],
  "rules": {
    "no-alert": 0,
    "prettier/prettier": [
      "error",
      {
        "jsxBracketSameLine": false,
        "trailingComma": "all",
        "singleQuote": true,
        "printWidth": 80,
        "semi": false
      }
    ]
  }
}

Auto Lint/Fix with VS Code

1. Install the ESLint package for VS Code

2. Now we need to setup some VS Code settings via Code/File → Preferences → Settings. It's easier to enter these settings from settings.json file, so click the {} icon in the top right corner:

{
  // Turn off "formatOnSave" for JS and JSX, we will set eslint to do this
  "[javascript]": {
    "editor.formatOnSave": false
  },
  "[javascriptreact]": {
    "editor.formatOnSave": false
  },
  // Tell the ESLint plugin to run on save
  "editor.codeActionsOnSave": {
    "source.fixAll": true
  },
  // Turn off prettier for JS and JSX because we are doing it through eslint already
  "prettier.disableLanguages": ["javascript", "javascriptreact"],
}
