eslint-plugin-prettier 
Runs Prettier as an ESLint rule and reports differences as individual ESLint issues.
If your desired formatting does not match Prettier’s output, you should use a different tool such as prettier-eslint instead.
Please read Integrating with linters before installing.

Installation
npm install --save-dev eslint-plugin-prettier eslint-config-prettier
npm install --save-dev --save-exact prettier
eslint-plugin-prettier
does not install Prettier or ESLint for you. You must install these yourself.
This plugin works best if you disable all other ESLint rules relating to code formatting, and only enable rules that detect potential bugs. If another active ESLint rule disagrees with prettier
about how code should be formatted, it will be impossible to avoid lint errors. Our recommended configuration automatically enables eslint-config-prettier
to disable all formatting-related ESLint rules.
Configuration (legacy: .eslintrc*
)
For legacy configuration, this plugin ships with a plugin:prettier/recommended
config that sets up both eslint-plugin-prettier
and eslint-config-prettier
in one go.
Add plugin:prettier/recommended
as the last item in the extends array in your .eslintrc*
config file, so that eslint-config-prettier
has the opportunity to override other configs:
{
"extends": ["plugin:prettier/recommended"]
}
This will:
- Enable the
prettier/prettier
rule.
- Disable the
arrow-body-style
and prefer-arrow-callback
rules which are problematic with this plugin - see the below for why.
- Enable the
eslint-config-prettier
config which will turn off ESLint rules that conflict with Prettier.
Configuration (new: eslint.config.js
)
For flat configuration, this plugin ships with an eslint-plugin-prettier/recommended
config that sets up both eslint-plugin-prettier
and eslint-config-prettier
in one go.
Import eslint-plugin-prettier/recommended
and add it as the last item in the configuration array in your eslint.config.js
file so that eslint-config-prettier
has the opportunity to override other configs:
const eslintPluginPrettierRecommended = require('eslint-plugin-prettier/recommended');
module.exports = [
// Any other config imports go at the top
eslintPluginPrettierRecommended,
];
This will:
- Enable the
prettier/prettier
rule.
- Disable the
arrow-body-style
and prefer-arrow-callback
rules which are problematic with this plugin - see the below for why.
- Enable the
eslint-config-prettier
config which will turn off ESLint rules that conflict with Prettier.
Svelte
support
We recommend to use eslint-plugin-svelte
instead of eslint-plugin-svelte3
because eslint-plugin-svelte
has a correct eslint-svelte-parser
instead of hacking.
When use with eslint-plugin-svelte3
, eslint-plugin-prettier
will just ignore the text passed by eslint-plugin-svelte3
, because the text has been modified.
If you still decide to use eslint-plugin-svelte3
, you'll need to run prettier --write *.svelte
manually.
arrow-body-style
and prefer-arrow-callback
issue
If you use arrow-body-style or prefer-arrow-callback together with the prettier/prettier
rule from this plugin, you can in some cases end up with invalid code due to a bug in ESLint’s autofix – see issue #65.
For this reason, it’s recommended to turn off these rules. The plugin:prettier/recommended
config does that for you.
You can still use these rules together with this plugin if you want, because the bug does not occur all the time. But if you do, you need to keep in mind that you might end up with invalid code, where you manually have to insert a missing closing parenthesis to get going again.
If you’re fixing large of amounts of previously unformatted code, consider temporarily disabling the prettier/prettier
rule and running eslint --fix
and prettier --write
separately.
Options
Note: While it is possible to pass options to Prettier via your ESLint configuration file, it is not recommended because editor extensions such as prettier-atom
and prettier-vscode
will read .prettierrc
, but won't read settings from ESLint, which can lead to an inconsistent experience.
