# func-args

    ECMAScript Function Arguments parser, Get arguments of a function, useful for and used in dependency injectors. Works for regular functions, generator functions and arrow functions.

```nodemon

npm install func-args

```

## api

* [index.d.ts](index.d.ts)

* by default will throw error if func is native or bounded func

## demo

see [_tests.ts](test/_tests.ts)

```ts

import { parseFunc } from 'func-args';

let fn = async (a, b, c, {e, d, }, [aa1, aa2, { aaa3 }, [ bbb1, bbb2, { bbb4 } ], ...rrr], e2 = null, f = {

		g: 7,

		a: 8,

		b: {

			c: 555,

			d: true,

		},

	},

	f2 = (333), ...argv) => {};

let { args, params } = parseFunc(fn);

console.dir({

	/**

	 * func args with structure

	 */

	args,

	/**

	 * all func args name

	 *

	 * @type string[]

	 */

	params,

}, {

	depth: 6,

});

/*

{ args:

   [ 'a',

     'b',

     'c',

     { e: 'e', d: 'd' },

     [ 'aa1',

       'aa2',

       { aaa3: 'aaa3' },

       [ 'bbb1', 'bbb2', { bbb4: 'bbb4' } ],

       '...rrr' ],

     'e2',

     'f',

     'f2',

     '...argv' ],

  params:

   [ 'a',

     'b',

     'c',

     'e',

     'd',

     'aa1',

     'f2',

     '...argv' ] }

 */

// skip throw error if func is native or bounded func

console.dir(parseFunc(Math.abs, true), {

	depth: 6,

});

/*

{ type: undefined,

  name: 'abs',

  native: true,

  generator: undefined,

  async: undefined,

  args: [],
