The problem

You have a bunch of files that you want to format using prettier-eslint. But prettier-eslint can only operate on strings.

This solution

This is a CLI that allows you to use prettier-eslint on one or multiple files. prettier-eslint-cli forwards on the filePath and other relevant options to prettier-eslint which identifies the applicable ESLint config for each file and uses that to determine the options for prettier and eslint --fix.


This module is distributed via npm which is bundled with node and should be installed (with yarn) as one of your project's devDependencies:

yarn add --dev prettier-eslint-cli

If you're still using the npm client: npm install --save-dev prettier-eslint-cli


Typically you'll use this in your npm scripts (or package scripts):

  "scripts": {
    "format": "prettier-eslint \"src/**/*.js\""

This will format all .js files in the src directory. The argument you pass to the CLI is a glob and you can pass as many as you wish. You can also pass options.


Vim users can add the following to their .vimrc:

autocmd FileType javascript set formatprg=prettier-eslint\ --stdin

This makes prettier-eslint-cli power the gq command for automatic formatting without any plugins. You can also add the following to your .vimrc to run prettier-eslint-cli when .js files are saved:

autocmd BufWritePre *.js :normal gggqG

CLI Options

prettier-eslint --help
Usage: prettier-eslint <globs>... [--option-1 option-1-value --option-2]
  -h, --help       Show help                                           [boolean]
  --version        Show version number                                 [boolean]
  --write          Edit the file in-place (beware!)   [boolean] [default: false]
  --stdin          Read input via stdin               [boolean] [default: false]
  --eslint-ignore  Only format matching files even if they are not ignored by
                   .eslintignore. (can use --no-eslint-ignore to disable this)
                                                       [boolean] [default: true]
  --eslintPath     The path to the eslint module to use
    [default: "<path-to-root>/node_modules/eslint"]
  --prettierPath   The path to the prettier module to use
  [default: "<path-to-root>/node_modules/prettier"]
  --ignore         pattern(s) you wish to ignore (can be used multiple times and
                   includes **/node_modules/** automatically)
  --log-level, -l  The log level to use
        [choices: "silent", "error", "warn", "info", "debug", "trace"] [default:

Any number of globs you wish to use to match the files you wish to format. By default, glob will ignore **/node_modules/** unless the glob you provide includes the string node_modules.


By default prettier-eslint will simply log the formatted version to the terminal. If you want to overwrite the file itself (a common use-case) then add --write. You should quote your globs, otherwise your terminal will expand the glob before it gets to prettier-eslint (which can have unexpected results):

  "scripts": {
    "format": "prettier-eslint --write \"src/**/*.js\""

NOTE: It is recommended that you keep your files under source control and committed before running prettier-eslint --write as it will overwrite your files!


Accept input via stdin. For example:

echo "var   foo =    'bar'" | prettier-eslint --stdin
# results in: "var foo = 'bar';" (depending on your eslint config)


Forwarded as the eslintPath option to prettier-eslint


Forwarded as the prettierPath option to prettier-eslint


Forwarded as logLevel option to prettier-eslint


Disables application of .eslintignore to the files resolved from the glob. By default, prettier-eslint-cli will exclude files if they are matched by a .eslintignore. Add this flag to disable this behavior.

Note: You can also set the LOG_LEVEL environment variable to control logging in prettier-eslint
