A Prettier configuration based off the Airbnb JavaScript style guide

Installation

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

Usage

In your package.json:

{
  "name": "my-library",
  "version": "1.0.0",
  "prettier": "@trxn/prettier-config"
}

If you don't want to use your package.json, you can create a .prettierrc.json file in your projects root directory.

'@trxn/prettier-config';

If you would like to extend or modify these properties, create a .prettierrc.js file in your projects root directory and export your desired modifications.

module.exports = {
  ...require('@trxn/prettier-config'),
  printWidth: 120,
};

Properties

3.6 Quote Props

Only quote properties that are invalid identifiers.

"quoteProps": "as-needed"

6.1 Quotes

Use single quotes instead of double quotes.

"singleQuote": true

8.2 Arrow Function Parentheses

Remove parentheses around a sole arrow function parameter.

"arrowParens": "avoid"

19.1 Tabs and Tab Width

Use soft tabs (space character) set to 2 spaces.

"tabWidth": 2

"useTabs": false

19.3 Print Width and Wrapping

Specify the line length that the printer will wrap on. Wrap prose if it exceeds the print width.

19.11 Bracket Spacing

Do not print spaces between brackets in object literals.

20.2 Trailing Commas

21.1 Semicolons

Print semicolons at the ends of statements.

"semi": true

JSX Properties

Prettier allows some React/JSX properties to be configured. If your project doesn't use React, no need to worry; these properties won't be applied to your project!

Quotes

Use double quotes in JSX.

"jsxSingleQuote": false
