func-deps v0.1.1

func-deps

Determines a function's dependencies based on its signature or annotations

Similar to the AngularJS $injector

Installation

npm install func-deps

Usage

Call func-deps with a function, and it returns an object with two properties: deps and func.

var funcDeps = require('func-deps');

funcDeps(function(){});
// => returns { deps: [], func: function(){} }

funcDeps(function(a, b){});
// => returns { deps: ['a', 'b'], func: function(a, b){} }

You can also pass func-deps an array, where the first args are string dependencies, and the last arg is the function.

var funcDeps = require('func-deps');

funcDeps(['a', 'b', function(c, d){}]);
// => returns { deps: ['a', 'b'], func: function(c, d){} }

funcDeps(['a', 'b', function(){}]);
// => returns { deps: ['a', 'b'], func: function(){} }

If no array annotation is provided, and the function has a $inject property that is an array, the $inject property is assumed to be the dependency list.

var funcDeps = require('func-deps');

function test() {};
test.$inject = ['a', 'b'];
funcDeps(test);
// => returns { deps: ['a', 'b'], func: function test(){} }
