Prettier Formatter for Visual Studio Code

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

Installation

Install through VS Code extensions. Search for Prettier - Code formatter

Visual Studio Code Market Place: Prettier - Code formatter

Can also be installed in VS Code: Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.

ext install esbenp.prettier-vscode

⚠ A word of warning-if you have any other code formatting extensions installed such as for example hugely popular HookyQR.beautify or taichi.react-beautify they might take precedence and format your code instead of Prettier leading to unexpected results.

Usage

Using Command Palette (CMD/CTRL + Shift + P)

1. CMD + Shift + P -> Format Document
OR
1. Select the text you want to Prettify
2. CMD + Shift + P -> Format Selection

Keyboard Shortcuts

Visual Studio Code provides default keyboard shortcuts for code formatting. You can learn about these for each platform in the VS Code documentation.

If you don't like the defaults, you can rebind editor.action.formatDocument and editor.action.formatSelection in the keyboard shortcuts menu of vscode.

Format On Save

Respects editor.formatOnSave setting.

You can turn on format-on-save on a per-language basis by scoping the setting:

// Set the default
"editor.formatOnSave": false,
// Enable per-language
"[javascript]": {
    "editor.formatOnSave": true
}

Plugins

This extension support Prettier plugins when you are using a locally resolved version of prettier. If you have Prettier and a plugin registered in your package.json, this extension will attempt to register the language and provide automatic code formatting for the built-in and plugin languages.

VSCode ESLint and TSLint Integration

Previous versions of this extension included ESLint, and TSLint integrations out of the box. This functionality was extremely error prone and counter to the best practices of what Prettier is now recommending for integrating with linters. To continue to use Prettier and your linter we recommend you use the ESLint or TSLint extensions directly.

You can enable Auto-Fix on Save for either TSLint or ESLint and still have formatting and quick fixes:

"eslint.autoFixOnSave": true,
"tslint.autoFixOnSave": true,

NOTE: If you are seeing conflicts between Prettier and ESLint this is because you don't have the right ESLint or TSLint rules set as explained in the Prettier documentation.
