prettier-eslint-cli

CLI for prettier-eslint

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.

Installation

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

Usage

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

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]

Options:
  -h, --help      Show help                                            [boolean]
  --version       Show version number                                  [boolean]
  --write         Edit the file in-place (beware!)              [default: false]
  --stdin         Read input via stdin                          [default: false]
  --eslintPath    The path to the eslint module to use
    [default: "<your_project>/node_modules/eslint"]
  --prettierPath  The path to the prettier module to use
  [default: "<your_project>/node_modules/prettier"]
  --log           Show logs                                     [default: false]
  --sillyLogs     Show silly amount of logs (good for debugging)[default: false]

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.

--write

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.

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!

--stdin

Accept input via stdin. For example:

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

--eslint-path

Forwarded as the eslintPath option to prettier-eslint

--prettier-path

Forwarded as the prettierPath option to prettier-eslint

--log

If prettier-eslint encounters an error formatting a file, it logs an error to the console. prettier-eslint-cli disables this behavior by default. You can turn it on with --log.

--silly-logs

This will be forwarded onto prettier-eslint as (sillyLogs) and is useful for debugging.
