grunt-prettier

Prettier plugin for Grunt

Getting Started

This plugin requires Grunt ~1.0.3

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-prettier --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-prettier');

The "prettier" task

Overview

In your project's Gruntfile, add a section named prettier to the data object passed into grunt.initConfig().

grunt.initConfig({ prettier: { options: { // Task-specific options go here. progress: false // By default, a progress bar is not shown. You can opt into this behavior by passing true. }, your_target: { // Target-specific file lists and/or options go here. }, }, });

Options

All options you can see in official Prettier repo.

You can put .prettierrc near Gruntfile.js. Options from .prettierrc merge with task config and default options in next order: [default config] < [task config] < [.prettierrc].

You dont need to add path to config file to task definition!

Usage Examples

Default Options

In this example, the default options are specified like prettier-cli.

grunt.initConfig({ prettier: { files: { 'dest/default_options': ['src/unformatted.js', 'src/another_unformatted.js'] } } });

Custom Options

In this example, custom options are used to transform indentation into tabs and use single quotes instead of double quotes.

grunt.initConfig({ prettier: { options: { singleQuote: true, useTabs: true }, files: { 'dest/default_options': ['src/testing', 'src/123'], } } });

Supported and tested "files" params

You can use following formats:

• File to file - format source file and put formatted code to destination file.

files: { "dest/formatted.js": "src/unformatted.js" }

• Concat and format - concat all source files, then format and put to destination file. This format can be used with glob patterns.

files: { "dest/formatted.js": [ "src/unformatted_1.js", "src/unformatted_2.js" ] }

• Hot formatting - overwrite src files with it formatted copy. Set src option instead of files. This format can be used with glob patterns.

files: { src: [ "my-awesome-project/**.js", "!my-awesome-project/**.config.js" ] }

Testing

To run unit tests grunt test

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
