instsure v0.2.1

Instsure

Instsure is a function wrapper to ensure the object initialitation, preventing wrong callings to the constructor function without right context.

Installation

Install with npm install instsure --save.

Usage

To use, add the require node module or use browserify if you want to use in a browser:

    // Wrapper Function

    const Instsure = require('instsure');

    var ConstructorWrapFoo = Instsure(function() {
        this.args = arguments;
        this.context = this;
    });

    ConstructorWrapFoo.prototype.foo = 'bar'

    var instance = new ConstWrapFoo(1,2,3,4),
        // or
        instance = ConstWrapFoo(1,2,3,4),
        // or
        instance = ConstWrapFoo.new([1,2,3,4]);

        console.log(instance.args) // [1,2,3,4];

        console.log(instance instanceof ConstWrapFoo); // true

    // Existing Constructor

    const Instsure = require('instsure');

    var ConstructorFoo = function() {
        this.args = arguments;
        this.context = this;
    };

    ConstructorWrapFoo.prototype.foo = 'bar'

    var instance = new Instsure(ConstructorFoo)(1,2,3,4),
        // or
        instance = Instsure(ConstructorFoo)(1,2,3,4),
        // or
        instance = Instsure(ConstructorFoo).new([1,2,3,4]);

        console.log(instance.args) // [1,2,3,4];

        console.log(instance instanceof ConstructorFoo); // true

        console.log(instance instanceof ConstructorWrapFoo); // true
