# no-empty-function-plugin

A Deno lint plugin that disallows empty function bodies.

## Rule Details

This rule flags any function declarations, function expressions, or arrow functions that have empty bodies. Empty function bodies often indicate incomplete implementations or dead code.

## Installation

```json

// deno.json

{

  "lint": {

    "plugins": ["jsr:@armaanas/no-empty-function@0.3.0"]

  }

}

```

## ❌ Invalid Examples

```js

function foo() {}

const bar = function* () {};

const baz = () => {};

class Example {

  constructor() {}

  foo() {}

}

```

```txt

error[no-empty-function-rule/no-empty-function]: Empty function body

 --> /home/user/deno/lint/example.ts:1:16

  |

1 | function foo() {}

  |                ^^

  = hint: Add code or comment to the empty function body

```

## ✅ Valid Examples

```js

function foo() {

  return true;

}

const bar = function () {

  return "node".split("").sort().join("");

};

const baz = () => 42;

class Example {

  constructor() {

    this.foo = 3.14;

  }

}

function foo1() {

  /* no-op */

}

```
