Sharing a Prettier configuration Prettier config.

yarn add --dev prettier-config-webchannel

or

npm install prettier-config-webchannel --save-dev

In your package.json:

{
  "name": "my-library",
  "version": "1.0.0",
  "prettier": "prettier-config-webchannel"
}

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

"prettier-config-webchannel"

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('prettier-config-webchannel'),
  printWidth: 120
};

Only quote properties that are invalid identifiers.

Remove parentheses around a sole arrow function parameter.

"arrowParens": "avoid"

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

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!

Use double quotes in JSX.

"jsxSingleQuote": false

If your component has multi-line properties, close its tag on a new line.

"jsxBracketSameLine": false
