JS : astuces VSCode

Discovering little tricks like that can really streamline your workflow. Here are some more tips and tricks for making the most out of your coding experience in VS Code, especially when you're working with Node.js:

1. Integrated Terminal

You already found out about using the terminal in VS Code, but did you know you can split terminals? Use Ctrl + Shift + 5 (or Cmd + Shift + 5 on Mac) to open a split terminal. This is great for running a server in one terminal while executing scripts or running tests in another.

2. Debugger

VS Code has a built-in debugger that works seamlessly with Node.js. Set breakpoints in your code by clicking in the gutter next to the line numbers, and then press F5 to start the debugger. You can step through your code, inspect variables, and view call stacks, making it much easier to find and fix issues.

3. Live Server Extension

If you're working on web projects, the Live Server extension is a game-changer. It automatically refreshes your browser whenever you save changes to your HTML, CSS, or JavaScript files. Just install the extension, right-click your index.html file, and select "Open with Live Server."

4. Emmet Abbreviations

For HTML and CSS, Emmet abbreviations can save you tons of time. For example, typing ul>li*5 and pressing Tab will generate an unordered list with five list items. It's like magic!

5. Prettier Extension

The Prettier code formatter helps keep your code consistent and clean. Install the Prettier extension and then format your code with Alt + Shift + F (or Option + Shift + F on Mac). You can also configure it to format your code on save.

6. Code Snippets

Custom snippets can speed up your coding. Go to File > Preferences > User Snippets and create a new snippet file for JavaScript. For example, you can create a snippet for a console log:

"log": {
    "prefix": "clg",
    "body": ["console.log('$1');"],
    "description": "Log output to console"
}

Now, typing clg followed by Tab will expand to console.log();.

7. IntelliSense

VS Code’s IntelliSense offers intelligent code completion, parameter info, and member lists. For JavaScript, it’s particularly useful when dealing with complex objects or unfamiliar libraries. You can trigger it manually by pressing Ctrl + Space.

8. Extensions for Node.js

There are a few must-have extensions for Node.js developers:

• Node.js Extension Pack: A collection of useful extensions like npm, ESLint, and Node.js Modules Intellisense.
• Nodemon: This extension allows you to use the Nodemon utility which automatically restarts your Node.js application when file changes in the directory are detected.

9. Source Control Integration

VS Code has Git integration built-in. You can manage your repositories, stage changes, make commits, and even resolve merge conflicts directly from the editor. Use the Source Control panel on the left sidebar for all your Git operations.

10. Command Palette

The Command Palette (Ctrl + Shift + P or Cmd + Shift + P on Mac) is the gateway to all VS Code commands. You can quickly search and execute commands, open files, and run extensions without leaving your keyboard.

11. Multi-Cursor Editing

Place multiple cursors in your code by holding Alt (or Option on Mac) and clicking where you want to add a cursor. You can also use Ctrl + Alt + Down (or Cmd + Option + Down on Mac) to add a cursor below the current line. This is super handy for making the same edit in multiple places.

12. Explorer Shortcuts

Navigate your files quickly using the explorer panel on the left. Ctrl + P (or Cmd + P on Mac) brings up the quick open file menu, allowing you to jump to any file in your project with just a few keystrokes.

13. Task Runner

You can define tasks in VS Code to run scripts or commands with ease. Create a tasks.json file in the .vscode folder of your project and configure tasks like building your project or running tests.

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "npm run build",
            "problemMatcher": []
        }
    ]
}

Now you can run your build task from the Command Palette or the terminal.

14. Code Lens

For JavaScript, Code Lens shows inline references to functions and variables, making it easier to see where they are used. Enable it in settings under Editor: Code Lens.

15. Bracket Pair Colorization

To make nested code easier to read, enable bracket pair colorization. This can be done by adding "editor.bracketPairColorization.enabled": true to your settings.json file.
