prettier-plugin-x


Use pretty printer with enhanced estree printer options from prettierX,
all in a Prettier plugin.

Supported parsers:

- Babel
- Microsoft TypeScript

Requires explicit configuration of parser. Recommended configuation helpers:

- prettier-config-x
- prettier-config-x-standard

Recommended alternative: prettier-plugin-x-babel,
with fixed use of Babel parser for ES languages JavaScript, Flow, and TypeScript.

Includes options from prettierX for
improved consistency with "Standard JS" formatting,
for example:

``js
function * a () {}

console.log(typeof a)
`

with the following .prettierrc configuration:

`js
{
semi: false,
generatorStarSpacing: true,
spaceBeforeFunctionParen: true
}
`

Note that for the non-Babel x-typescript parser this plugin uses the TypeScript parser that is bundled with stock Prettier.

Installation

with Yarn (recommended):

`console
yarn add --dev prettier-plugin-x
`

or with npm:

`console
npm install --save-dev prettier-plugin-x
`

Sample usage

`console
prettier --config ./sample-prettierx-prettierrc --parser=x-babel --check sample.js
`

with babel-ts parser:

`console
prettier --config ./sample-prettierx-prettierrc --parser=x-babel-ts --check sample.js
`

or with the TypeScript parser:

`console
prettier --config ./sample-prettierx-prettierrc --parser=x-typescript --check sample.js
`

with babel-flow parser:

`console
prettier --config ./sample-prettierx-prettierrc --parser=x-babel-flow --check sample.js
`
