How to fix just one rule using eslint

I want to use eslint command flag --fix to just fix one rule. And I tried the command: eslint --fix --config ./.eslintrcsomerules.js .. But it does not work. How to achieve the object?

My .eslintrcsomerules.js file is below:

module.exports = {
  'rules': {
    'indent': [2, 2],
  }
};

To fix the issues caused by just one rule, you need to combine --fix --rule with --no-eslintrc. Otherwise your rule will just be merged with your existing configuration and all fixable issues will be corrected. E.g.

$ eslint --no-eslintrc --fix --rule 'indent: [2, 2]'

Depending on your setup you'll need to re-add mandatory settings from your ESLint configuration to the command line for the lint run to succeed. In my case I had to use

$ eslint --no-eslintrc --parser babel-eslint --fix --rule 'indent: [2, 2]'

new eslint versions (eslint.config.js)

For eslint > 9.x (not sure about the lowest version) use a new option name:

$ eslint --no-config-lookup --fix --rule 'indent: [2, 2]'

The answers suggesting ignoring .eslintrc with

eslint --no-eslintrc --fix --rule 'indent: [2, 2]'

may fail if your .eslintrc contains preprocessors without which you get errors, such as

Parsing error: The keyword 'import' is reserved

I recommend using eslint-interactive, which will let you select the rules you want to fix:

yarn install -D eslint-interactive
eslint-interactive . # This will interactively guide you.
yarn remove -D eslint-interactive

I struggled with this. I was using create-react-app and it was very difficult to turn off all the rules but keep all the configs to parse ES6/TS/etc.

This library was exactly what I wanted! I can see how many errors there are for each rule and selectively fix one rule at a time

You can pass a --rule flag with the rule you want to fix. For example:

eslint --fix --rule 'quotes: [2, double]' .

Check out the official documentation for more information.

The list of available rules might also be helpful.
