How to Set Up a Vue Development Environment

Mastering Vue.js development starts with a well-configured environment. This guide shows you how to set up VS Codium (an open-source alternative to VS Code) for optimal Vue.js development, leveraging extensions, linters, and browser tools for enhanced productivity.

Key Highlights:

• VS Codium: Utilize VS Codium for a clean, open-source Vue development experience.
• Vetur Extension: Install the Vetur extension for superior Vue code support, including syntax highlighting, snippets, linting, and IntelliSense.
• Vue CLI: Employ Vue CLI to streamline project scaffolding and integrate essential tools like ESLint and Prettier.
• ESLint & Prettier: Configure ESLint and Prettier for consistent code style, error detection, and automatic formatting.
• Vue Devtools: Leverage Vue Devtools (browser extension) for efficient debugging and application state inspection.

Setting Up Your Editor (VS Codium):

Download and install VS Codium (or VS Code) for your operating system. We'll refer to it as VS Code for simplicity.

Installing the Vetur Extension:

1. Open VS Code.
2. Click the Extensions icon (square icon in the sidebar).
3. Search for "Vetur" and install the extension by Pine Wu.
4. Reload VS Code to activate the extension.

Vetur Features:

Vetur enhances Vue development with:

• Syntax Highlighting: Provides clear visual distinction of code elements within .vue files.
• Snippets: Offers pre-defined code snippets for faster development. Type "scaffold" for a quick SFC template.
• Emmet: Supports Emmet abbreviations for rapid HTML/CSS generation. Try div#header>h1.logo>a{site Name} and press Tab.
• Error Checking/Linting: Detects errors and potential issues in your code.
• IntelliSense: Provides intelligent code completion suggestions.

Example Project with Vue CLI:

1. Ensure Node.js is installed.
2. Install Vue CLI globally: npm install -g @vue/cli
3. Create a new project: vue create my-project
4. Select features manually during setup, choosing "ESLint Prettier" and "Lint on save," placing config files in package.json.

Linting with ESLint:

Vue CLI integrates ESLint for code quality checks. The eslint-plugin-vue plugin specifically handles .vue files. Errors are displayed in the terminal and (after installing the ESLint VS Code extension) within the editor. You can configure rules in your package.json file.

Formatting with Prettier:

Prettier automatically formats your code for consistency. Enable "formatOnSave" in VS Code settings (editor.formatOnSave: true) for automatic formatting upon saving. Configure Prettier rules in your package.json file.

Vue Browser Tools:

Install the Vue.js devtools browser extension (Chrome or Firefox). This allows inspection of components, Vuex store (if used), and emitted events during development.

Conclusion:

This setup provides a robust environment for Vue.js development. The combination of VS Codium, Vetur, Vue CLI, ESLint, Prettier, and Vue Devtools significantly enhances productivity and code quality. Remember to consult the documentation for each tool for advanced configuration options.
