eslint-plugin-no-mixed-operators

Fixable no-mixed-operators rule for eslint.

Why

The plugin originally comes from the need of supporting prettier to work with eslint. But since eslint/eslint#8916 didn't get enough consensus from the team, I figured to create a drop-in replaceable plugin myself.

Installation

yarn add -D eslint-plugin-no-mixed-operators

OR

npm install --save-dev eslint-plugin-no-mixed-operators

Usage

Use it like a regular plugin and disable the original one if it's already enabled.

// .eslintrc
{
  "plugins": ["no-mixed-operators"],
  "rules": [
    "no-mixed-operators": "off",
    "no-mixed-operators/no-mixed-operators": "error"
  ]
}

Then you can fix the code with --fix via eslint CLI.

eslint --fix .

Example

Considered the following code

a && b + c - d / e || f

will automatically be fixed to

(a && b + c - (d / e)) || f

Options

All original options are available.

Running Tests

yarn test # npm test

Running Demo

cd demo # change to the demo directory
yarn # npm install
yarn test # npm test

See demo/index.js for fixed changes.
