@danydodson/prettier-config NPM

prettier-config

Mine prettier configuration.

Pairs well with mine ESLint configuration.

Installation

yarn

yarn add --dev prettier
yarn add --dev @danydodson/prettier-config prettier

npm

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

Usage

We export two ESLint configurations for your usage:

Default Config

Create a prettier.config.js file at the root of your project that contains:

module.exports = require('@danydodson/prettier-config')

Four Spaces Config

If you prefer 4 spaces instead of 2, use this in your prettier.config.js instead:

module.exports = require('@danydodson/prettier-config/four-spaces')

Pre-commit Hook

As another line of defense, if you want Prettier to automatically fix your errors on commit, you can use pretty-quick with husky, which manage git hooks.

yarn add --dev prettier pretty-quick husky
npm install --save-dev prettier pretty-quick husky

Update your package.json like this:

{
  "husky": {
    "hooks": {
      "pre-commit": "pretty-quick --staged"
    }
  }
}

If you already have lint-staged running ESLint on precommit, you can just add pretty-quick on top of it:

{
  "husky": {
    "hooks": {
      "pre-commit": "pretty-quick --staged && lint-staged"
    }
  },
  "lint-staged": {
    "*.js": ["eslint --fix", "git add"]
  }
}

Enforced Rules

Check out all of Prettier's configuration options.

Print Width: Line wrap at 100 characters.
Tab Width: Spaces per indentation-level.
Tabs: Indent lines with spaces, not tabs.
Semicolons: Always print semicolons at the ends of statements.
```
const greeting = 'hi'
```
Quote: Use single quotes instead of double quotes.
```
const quote = 'single quotes are better'
```
Trailing Commas: Use trailing commas wherever possible.
```
const obj = {
  a: 'hi',
  b: 'hey'
}
```
Bracket Spacing: Print spaces between brackets in object literals.
```
{
  foo: bar
}
```
JSX Brackets: Put the > of a multi-line JSX element at the end of the last line instead of being alone on the next line (does not apply to self closing elements).
```
<button className='prettier-class' id='prettier-id' onClick={this.handleClick}>
  Click Here
</button>
```
Arrow Function Parentheses: Omit parens when possible.
```
x => x
```
