Avoid using numbers at the end of variable or function names.

Examples of incorrect code for this rule:

const foo1 = 1;
const bar2 = 2;

function baz3() {
  return 3;
}

Examples of correct code for this rule:

const foo = 1;
const bar = 2;

function baz() {
  return 3;
}

You can pass an allow option to specify a list of variable or function names that are allowed to have numbers at the end. By default, the rule allows s3 and v4 as they are common in the JavaScript world. (e.g. s3 for AWS S3, v4 for UUID v4)

{
  "clean-code/no-number": ["error", {
    "allow": ["s3", "v4"]
  }]
}

You can pass an allowRegex option to specify a list of regular expressions that are allowed to have numbers at the end.

{
  "clean-code/no-number": [
    "error",
    {
      "allowRegex": [
        "^foo[0-9]+$",
        "S3$"
      ]
    }
  ]
}

You can pass an extensions option to specify a list of file extensions that will be checked. By default, the rule checks .js, .jsx, .ts, and .tsx files.

{
  "clean-code/no-number": ["error", {
    "extensions": [".js", ".jsx", ".ts", ".tsx"]
  }]
}

npm install @kougen/eslint-plugin-clean-code

Add the plugin to your .eslintrc configuration file:

{
  "plugins": ["@kougen/clean-code"]
}

Then configure the rules you want to use under the rules section.

{
  "rules": {
    "@kougen/clean-code/no-number": "error"
  }
}

Add the following into your esling.config.js:

export default [
  {
    // .....
    plugins: {

      "clean-code": eslintCleanCode,
    },
    rules: {
      "clean-code/no-number": "error",
    }
  }
]
