@importvault/bindall

bindall ( ob , fns , selected )

API

• ob - Object to bind methods to.
• fns - is an object whose values get fixed bound to ob

optional

• selected - Array of string providing names of selected functions to bind - in case when binding needs to be done selectively.

Install

npm install @importvault/bindall

Internals

• reassign .this to fixed object for selected functions

• mutates fns that holds the functions

• Other implementation ( lodash, underscore ) of bindall does not provide option to control what fns is bound to.

• 40 lines of code.

Examples

. . binding all functions in object

livescript

var bindall = require("@importvault/bindall")

var log = function()
{
	console.log(this);
}

var ob =
{
	fuel:"coffee",
	fns:
	{
		foo:log
	}


}

ob.fns.foo() // { foo: [Function: foo] } // cannot access .fuel  :(

bindall(ob,ob.fns) // will mutate original object

ob.fns.foo() 
// { fuel: 'coffee', fns: { foo: [Function] } } // can access .fuel now !

. . for applying to a subset number of functions

livescript

var bindall = require("@importvault/bindall")

var log = function()
{
	console.log(this);
}

ob =
{
	fuel:"coffee",
	fns:
	{
		foo:log, 
		bar:log
	}
} 

bindall(ob , ob.fns , ["bar"])

ob.fns.bar() 
// { fuel: 'coffee', fns: { log: [Function] , bar: [Function] }}

ob.fns.foo() 
// { fns: { log: [Function] , bar: [Function] } }
