An eslint plugin to enforce method or function name conforms to conventions.

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install eslint-plugin-function-name:

npm install eslint-plugin-function-name --save-dev

Add function-name to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": [
    "function-name"
  ],
  "rules": {
    "function-name/starts-with-verb": "error"
  }
}

Function is always do something, so it should start with a verb and to avoid confusion with variables.

👎 Examples of incorrect code for this rule:

function cat(fish) {}
function dog(distance) {}

👍 Examples of correct code for this rule:

function feedCat(fish) {}
function walkDog(distance) {}

interface IOptions {
  whitelist: string[];
  blacklist: string[];
}

.eslintrc.js

{
  "rules": {
    "function-name/starts-with-verb": ["error", {
      "whitelist": ["success"],
      "blacklist": ["init"]
    }]
  }
}

👎 Examples of incorrect code for this rule:

// ..."blacklist": ["init"]...
const foo = {
  init() {},
}

👍 Examples of correct code for this rule:

// ..."whitelist": ["success"]...
const foo = {
  success() {},
}
