Settings

Prettier's Settings

Settings will be read from (listed by priority):

1. Prettier configuration file
2. .editorconfig

Or if no prettier configuration file exist

1. .editorconfig
2. VSCode prettier's settings (described below with their default)

prettier.printWidth (default: 80)

prettier.tabWidth (default: 2)

Number of spaces it should use per tab

prettier.singleQuote (default: false)

If true, will use single instead of double quotes

prettier.trailingComma (default: 'none')

Controls the printing of trailing commas wherever possible. Valid options:

• "none" - No trailing commas
• "es5" - Trailing commas where valid in ES5 (objects, arrays, etc)
• "all" - Trailing commas wherever possible (function arguments)

prettier.bracketSpacing (default: true)

Controls the printing of spaces inside object literals

prettier.jsxBracketSameLine (default: false)

If true, puts the > of a multi-line jsx element at the end of the last line instead of being alone on the next line

prettier.parser (default: 'babylon') - JavaScript only

Which parser to use. Valid options are 'flow' and 'babylon'.

prettier.semi (default: true)

Whether to add a semicolon at the end of every line (semi: true), or only at the beginning of lines that may introduce ASI failures (semi: false)

prettier.useTabs (default: false)

If true, indent lines with tabs

prettier.proseWrap (default: 'preserve')

(Markdown) wrap prose over multiple lines.

prettier.arrowParens (default: 'avoid')

VSCode specific settings

These settings are specific to VSCode and need to be set in the VSCode settings file. See the documentation for how to do that.

prettier.eslintIntegration (default: false) - JavaScript and TypeScript only

Use prettier-eslint instead of prettier. Other settings will only be fallbacks in case they could not be inferred from ESLint rules.

prettier.stylelintIntegration (default: false) - CSS, SCSS and LESS only

Use prettier-stylelint instead of prettier. Other settings will only be fallbacks in case they could not be inferred from stylelint rules.

prettier.requireConfig (default: false)

Require a 'prettierconfig' to format

prettier.ignorePath (default: .prettierignore)

Supply the path to an ignore file such as .gitignore or .prettierignore. Files which match will not be formatted. Set to null to not read ignore files. Restart required.

prettier.disableLanguages (default: [])

A list of languages IDs to disable this extension on. Restart required. Note: Disabling a language enabled in a parent folder will prevent formatting instead of letting any other formatter to run

Prettier resolution

This extension will use prettier from your project's local dependencies. Should prettier not be installed locally with your project's dependencies, a copy will be bundled with the extension.
