How to use Prettier in VS Code shortcut key?

In Visual Studio Code (VS Code), using Prettier to format code is a great way to improve coding efficiency. To execute Prettier formatting via keyboard shortcuts, follow these steps:

Install the Prettier Plugin

First, ensure you have installed the Prettier plugin in VS Code. You can install it by following these steps:

1. Open VS Code.
2. Go to the Extensions view in the sidebar, which can be opened by clicking the square icon on the left or using the shortcut Ctrl+Shift+X.
3. In the search box, type "Prettier - Code formatter".
4. Find the plugin and click "Install".

Set Up Keyboard Shortcuts

After installing the plugin, the next step is to set up a keyboard shortcut to execute code formatting:

1. Open the command palette using the shortcut Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac).
2. Type "Open Keyboard Shortcuts (JSON)" and select this command. This will open a JSON file where you can customize your shortcuts.
3. In the opened keybindings.json file, you need to add the following configuration:

json
{
    "key": "ctrl+alt+f",  // You can customize this shortcut combination as per your preference.
    "command": "editor.action.formatDocument",
    "when": "editorHasDocumentFormattingProvider && editorTextFocus && !editorReadonly"
}

In the above configuration, "ctrl+alt+f" is the set shortcut, which you can modify according to your preference. "editor.action.formatDocument" is the command to execute formatting.

Use Keyboard Shortcuts to Format Code

Once the shortcut is set, you can open a file in the editor and press your set shortcut; Prettier will automatically format your code. This is particularly useful when working with JavaScript, CSS, HTML, etc., as it quickly organizes code style and maintains consistency.

Example: Suppose you are writing a JavaScript file and the indentation, spaces, etc., are not properly used. You just need to press ctrl+alt+f (or your customized shortcut), and Prettier will automatically adjust these formats, making the code look cleaner and more readable.

This is how you can use the Prettier plugin in VS Code and set up keyboard shortcuts to format code. This method can significantly improve your code quality and work efficiency.
