# Constructor Decorator

Typized and autoassigned arguments for JS class constructor.

## Overview

Are you not tired of constantly writing like:

```js

class TypedEntity {

  constructor (

    foo,

    bar,

    baz,

    bat,

    fie,

    bal,

    fuu,

    faa

  ) {

    this.baz = baz

    this.bal = bal

    this.foo = foo

    this.fuu = fuu

    this.bar = bar

    this.bat = bat

    this.fie = fie

    this.faa = faa

  }

}

module.exports = TypedEntity

```

Now you can avoid of it with the class extend:

```js

const BaseClass = require('constructor-decorator')

const Foo = require('./Foo')

const Bar = require('./Bar')

const Baz = require('./Baz')

class TypedEntity extends BaseClass {

  get args () {

    return {

      foo: [Foo, Baz],

      bar: [Bar, String],

      baz: String,

      bat: Boolean,

      fie: String,

      bal: [String, Number],

      fuu: Date,

      faa: Number,

    }

  }

  constructor () {

    super(...arguments)

  }

}

module.exports = TypedEntity

```

The types compare is enabled with an array OR-operator syntax support.
