Configuring ESLint in Visual Studio Code

ESLint is a popular JavaScript linter that helps developers find and fix problems in their code. It can be configured to work with Visual Studio Code (VSCode) to provide real-time linting of your code. In this article, we will look at how to configure ESLint to work with VSCode.

The first step is to install the ESLint extension for VSCode. To do this, open the Extensions tab in VSCode and search for “ESLint”. Click the Install button to install the extension. Once installed, you should see the ESLint icon in the bottom right corner of the VSCode window.

The next step is to configure ESLint to work with your project. To do this, create an ESLint configuration file in the root folder of your project. This file is typically called .eslintrc.json. The contents of this file should look something like this:

{
    "env": {
        "browser": true,
        "es6": true
    },
    "extends": "eslint:recommended",
    "globals": {
        "Atomics": "readonly",
        "SharedArrayBuffer": "readonly"
    },
    "parserOptions": {
        "ecmaVersion": 2018,
        "sourceType": "module"
    },
    "rules": {
    }
}

This configuration sets up ESLint to work with the current version of JavaScript (ES6) and with the browser environment. You can find more information about configuring ESLint in the official ESLint documentation.

Once the configuration file is in place, you can enable ESLint in VSCode by opening the Settings tab (Ctrl + ,) and searching for “eslint”. Make sure that the “ESLint: Enable” setting is set to true. This will enable ESLint in VSCode.

You can also configure ESLint to work with specific files and folders in your project. To do this, edit the ESLint configuration file and add the following lines:

"overrides": [
    {
        "files": ["src/**/*.js"],
        "excludedFiles": ["src/vendor/**/*.js"],
        "rules": {
            "no-console": "off"
        }
    }
]

This configuration tells ESLint to lint all JavaScript files in the src folder, except for files in the vendor folder. It also tells ESLint to ignore the “no-console” rule for these files. You can find more information about configuring ESLint rules in the official ESLint documentation.

That’s all you need to do to configure ESLint to work with VSCode. Once you have saved your configuration, ESLint will start linting your code in real-time and provide you with helpful errors and warnings. Happy coding!
