@elegantech/prettier-multi-config

Multi-configurations presets for Prettier 3. Compatibility with some plugins (PHP, Blade templates, Bash, etc).

Requirements

• Prettier >= 3.0.0: Base prettier and plugins are compatible with Prettier >= 3 only.
• Node.js:
  • Minimum: 14.18.0 (for ESM config compatibility and default plugins)
• npm:
  • Minimum: 7.2.0 (automatic install of peerDependencies).

Note: Some optional plugins may require a more recent version of Node.js.

Installing

In the following instructions it will be used npm, but commands arguments are the same for yarn.

Add Prettier and this package to your project:

# Base Prettier 3
npm add -D --save-exact prettier

# This package
npm add -D @elegantech/prettier-multi-config

Prettier's team recommends to use --save-exact for prettier dependency.

Installing plugins dependencies

There are other optional dependencies that vary depending of the presets you are using. Check that sections for instructions.

Depending on how are you creating your own config file, you may choose to install the required plugins packages as:

• devDependencies (-D, --save-dev).
• peerDependencies (--save-peer).
• dependencies.

In the following plugin installation instructions, it is assumed you are building your configuration directly into your project, and therefore plugin packages should be installed as devDependencies (using the -D npm/yarn alias).

Available presets

There are some presets available with default configurations and plugins for specific languages or cases. These will help you create your own configuration file.

Check for examples in the Usage section.

Base preset (base)

Includes general base rules for all the languages/files officially supported by Prettier. Also, there are options for formatting the package.json file.

Required plugins:

• prettier-plugin-pkg

npm add -D prettier-plugin-pkg

PHP preset (php)

Compatibility with PHP.

Note: You need to set the phpVersion option depending of your PHP environment.

Required plugins:

• @prettier/plugin-php

npm add -D @prettier/plugin-php

Bash Script preset (sh)

Compatibility with Shell Script for Bash or sh.

Required plugins:

• prettier-plugin-sh

npm add -D prettier-plugin-sh

Multiline preset (multiline)

Multiline elements for some languages.

Required plugins:

• prettier-plugin-multiline-arrays

npm add -D prettier-plugin-multiline-arrays

Usage

Simple usage

Although this package is not intended to be used directly as a shared configuration or plugin, you can still use the default export as your prettier setup.

In your package.json:

{
  "prettier": "@elegantech/prettier-multi-config"
}

Or in your .prettierrc.json:

"@elegantech/prettier-multi-config"

This includes the base preset only.

You can use this technique to create your shared configuration using this package. 😉

Check out the following sections to create your own customized configuration file.

The config file

You have to use .js, .cjs or .mjs formats to be able to customize your presets. As you can see, this package it's available for ESM and CommonJs modules.

Remember: If your project is an ESM ({ "type": "module" } in your package.json), by using .prettierrc.js it will import the ESM build, but in the other hand, it will be required the commonjs version. To avoid this, you can use .cjs or .mjs extensions instead.

Initial state for .prettier.mjs:

/** @type {import("prettier").Config} */
const config = {
  // ...
};

export default config;

Read more about config formats in the Prettier documentation.

Examples

Note: Most of the following examples will assume you are using .prettierrc.mjs (ESM), but you are free to use .cjs format instead.

In your .prettier.mjs:

import {
  getMergedGlobalOptionsFor,
  getPluginsFor,
  getMergedOverrideFor,
} from '@elegantech/prettier-multi-config/presets';

const selectedPresets = [
  'base',
  'php',
  'sh',
];

/** @type {import("prettier").Config} */
const config = {
  // Add global configurations for selected presets
  ...getMergedGlobalOptionsFor(selectedPresets, {
    // Here you can add your own global options
  }),

  // Add plugins for selected presets
  plugins: getPluginsFor(selectedPresets, [
    // Here you can add other plugins
    'prettier-plugin-organize-imports',
  ]),

  overrides: [
    // Specific options for presets
    ...getMergedOverrideFor('base'),
    ...getMergedOverrideFor('php', {
      config: {
        // You can override some default options in the preset
        options: { phpVersion: '8.1' },
      },
    }),
    ...getMergedOverrideFor('sh'),

    // Here ypu can add your custom config override
    {
      files: ['.prettierrc.json'],
      options: {
        printWidth: 80,
      },
    },
  ],
};

The order of included options is respected. Be careful of options

Publish a package for your config file (🚧 WIP)

You can create a package that builds the config, using Typescript directly.

Check this example using unbuild to create a config.
