# yarn
yarn add eslint-formatter-simple --dev

How To Use

Via CLI:

$ eslint --format="simple" file.js

# Disable verbose output:
$ ESLINT_CFS_VERBOSE=false eslint --format="simple" file.js

With webpack via eslint-loader:

module.exports = {
  entry: "...",
  module: {
    rules: [
      {
        test: /\.js$/,
        use: [
          {
            loader: "eslint-loader",
            exclude: /node_modules/,
            options: {
              formatter: require("eslint-formatter-simple")
            }
          }
        ]
      }
    ]
  }
};

Getting Exit Error

If getting an error like the following when running as a npm/yarn script:

error Command failed with exit code 1.

Check the following eslint issue here. The solution is to add the following to the end of the script.

{
  scripts: {
    lint: "eslint ...; exit 0"
  }
}
