Essential VS Code Extensions for Web Development

In today's fast-paced web development world, efficiency and productivity are crucial. Developers need tools that streamline their workflow and ensure clean, maintainable code. Visual Studio Code (VSCode) has become one of the most popular code editors, thanks to its flexibility and vast ecosystem of extensions. The right extensions can significantly improve code quality and boost collaboration. In this blog, we'll explore essential VSCode extensions that every modern web developer should have in their toolkit.

An Extension for Everything

Visual Studio Code (VSCode) extensions are add-ons that boost the editor's functionality, letting developers tailor their coding environment. These tools offer a variety of features - from syntax highlighting and code formatting, to debugging and version control integration. Whether you're tackling a small project or a large-scale application, the right extensions can greatly improve your development experience, making coding more efficient and enjoyable. Below, we will discover various and useful extensions together!

Prettier ESLint

Prettier ESLint combines the benefits of Prettier and ESLint. It automatically formats your code using Prettier while ensuring it follows your ESLint rules. Prettier handles formatting (like indentation and spacing), while ESLint enforces code quality and style rules. This combination streamlines development by making your code stylistically consistent and aligned with team standards.

How to Use Prettier ESLint

  • Install Prettier, ESLint, and other needed prerequisites (we are using this with Typescript today):

      npm i -D prettier@^3.1.0 eslint@^8.52.0 prettier-eslint@^16.1.2 @typescript-eslint/parser@^5.0.1 typescript@^4.4.4
          
  • Configure Prettier and ESLint:

    • Open or create a settings.json file at the root of the project. Paste in the following settings.

        {
                "editor.defaultFormatter": "rvest.vs-code-prettier-eslint",
                "editor.formatOnType": false, // required
                "editor.formatOnPaste": true, // optional
                "editor.formatOnSave": true, // optional
                "editor.formatOnSaveMode": "file", // required to format on save
                "files.autoSave": "onFocusChange", // optional but recommended
                "vs-code-prettier-eslint.prettierLast": false // set as "true" to run 'prettier' last not first
              }
            
  • Install the Prettier ESLint Extension in VSCode:

    • Search for Prettier ESLint in the extensions tab in VSCode. Hit install.
