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
