function-apply

Allows to apply functions to hash-maps of arguments

Features

  • Binds argument object keys to function argument names
  • Works with objects and arrays

Motivation

HTTP requests, configuration objects, settings for JavaScript apps come in form of JSON objects. Yet, we usually prefer to write our functions in classical manner: listing and naming all the required parameters. Mapping incoming objects to function parameters might become repetitive and make the code harder to read. Especially, when dealing with higher-order functions that don't necessarily know their products' arguments.

One more thing: naming arguments in function calls can sometimes make them easier to understand:

var result = myFunction({data: 100, callback: myCallback})

Installation

npm install function-apply

Usage

var apply = require('function-apply');
 
// Argument name binding
var multiply = apply(function (number, multiplier) {
    return number * multiplier;
});
 
var result = multiply({
    number: 100,
    multiplier: 2
})
 
 
// Object application
var config = [{
    url: 'http://my.url',
    method: 'get'
}, {
    url: 'http://my.url',
    method: 'get'
}];
 
function createRoute(url, method) {
    ......
}
 
var routes = config.map(apply(createRoute));
