inject-params

Dynamic argument injection using function parameters.

Install

npm install inject-params

Usage

Arguments are dynamically injected into a function based on the parameters it expects.

Arguments can be retrieved from an object using its keys.

var injectParams = require("inject-params");

var allOptions = {
  firstName: "John",
  lastName: "Doe",
  callNow: function () {
    // ...
  }
};

function callJohn(callNow, lastName) {
  // ...
}

injectParams(callJohn, allOptions);

Arguments can also be retrieved using a lookup function.

var injectParams = require("inject-params");

function lookupParams(key) {
  // ...
  return someVal;
}

function contactSomePerson(details, emailNow) {
  // ...
}

injectParams(contactSomePerson, lookupParams);
