@excelsia/prettier-config v1.0.1

@excelsia/prettier-config

A Prettier shareable config for projects using Prettier separate processes.

Installation

npm

npm install --save-dev @excelsia/prettier-config

yarn

yarn add --dev @excelsia/prettier-config

pnpm

pnpm add -D @excelsia/prettier-config

This is only a shareable configuration. It does not install Prettier, Standard, ESLint, or any other part of the tool chain.

Usage

To use this config in your project, you will need to add the following to your Prettier configuration. You should choose one based on your project's current config.

// `.prettierrc.json`
"@excelsia/prettier-config"

// `prettier.config.js` or `.prettierrc.js`
module.exports = '@excelsia/prettier-config'

Extending Shared Configurations

This configuration is not intended to be changed, but if you have a setup where modification is required, it is possible. Prettier does not offer an "extends" mechanism as you might be familiar from tools such as ESLint.

To extend a configuration you will need to:

1. Import/Require this sharable config from within your own configuration. This means you must be using a JavaScript version of a Prettier configuration file.
2. Extend your modification on top of the shared config using something like Object destructuring, Object.assign(), or lodash.merge()
3. Export the modified configuration

Prettier uses cosmiconfig for configuration file support. This means you can configure prettier via:

• A .prettierrc file, written in YAML or JSON, with optional extensions: .yaml/.yml/.json.
• A .prettierrc.toml file, written in TOML (the .toml extension is required).
• A prettier.config.js or .prettierrc.js file that exports an object.
• A "prettier" key in your package.json file.

...

Sharing configurations

Note: This method does not offer a way to extend the configuration to overwrite some properties from the shared configuration. If you need to do that, import the file in a .prettierrc.js file and export the modifications, e.g:

module.exports = {
  ...require("@excelsia/prettier-config"),
  semi: false
};

For example, if you need to change it so that semicolons are required:

// `prettier.config.js` or `.prettierrc.js`
const prettierConfigStandard = require('@excelsia/prettier-config')
const merge = require('lodash.merge')

const modifiedConfig = merge(
  {},
  prettierConfigStandard,
  {
    semi: true,
    // ... other modified settings here
  }
)

module.exports = modifiedConfig
