In order to follow along the tutorial series, I recommend you to use Visual Studio Code Editor and install & apply the below extensions and settings.

Install the below extensions:

• ESLint
• Prettier
• Path Autocomplete

Go to your Visual Stuido Code settings.json file and add the below settings there:

// config related to code formatting
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": true,
"[javascript]": {
  "editor.formatOnSave": false,
  "editor.defaultFormatter": null
},
"editor.codeActionsOnSave": {
  "source.fixAll.eslint": true,
  "source.organizeImports": true
},
"eslint.alwaysShowStatus": true

Make sure in your VS Code Editor, "LF" is selected as line feed instead of CRLF (Carriage return and line feed). To do that, just click LF/CRLF in bottom right corner of editor, click it and change it to "LF". If you dont do that, you will get errors in my setup.

In order to lint and format your code automatically according to popular airbnb style guide, I recommend you to follow the instructions as described in video. References are as below.

yarn add -D eslint prettier
npx install-peerdeps --dev eslint-config-airbnb-base
yarn add -D eslint-config-prettier eslint-plugin-prettier

Create a .eslintrc.json file in the project root and enter the below contents:

{
    "extends": ["prettier", "airbnb-base"],
    "parserOptions": {
        "ecmaVersion": 12
    },
    "env": {
        "commonjs": true,
        "node": true
    },
    "rules": {
        "no-console": 0,
        "indent": 0,
        "linebreak-style": 0,
        "prettier/prettier": [
            "error",
            {
                "trailingComma": "es5",
                "singleQuote": true,
                "printWidth": 100,
                "tabWidth": 4,
                "semi": true
            }
        ]
    },
    "plugins": ["prettier"]
}
