Advanced tools
If you work with a lot of generic objects ({}
) in your code and you want to give special behavior to some or all of them, then BlueprintJS is the right tool for you.
var User = blueprint({
name: "",
lastName: "",
fullName: function () {
"use strict";
// Never use this.name, always use the "get" and "set" methods
return this.get("name") + " " + this.get("lastName");
}
});
User
Blueprintvar someObjectIHaveInMyProject = {name: "Robert", lastName: "Baratheon"};
var user = new User(someObjectIHaveInMyProject);
// Now you get the "fullName" method for free. Bargain!
console.log(user.get("fullName")); // Robert Baratheon
user.set("lastName", "Downey Jr.");
console.log(user.get("fullName")); // Robert Downey Jr.
user
blueprintObject into a plain objectvar userPlainObject = blueprint.toPlainObject(user);
// Note that the fullName method is now a property with a value that is the
// result of that method
console.log(user.fullName); // Robert Downey Jr.
var listOfObjects = [
{name:"John", lastName: "Blue"},
{name:"Mary", lastName: "Red"},
{name:"Richard", lastName: "Green"},
{name:"Michael", lastName: "Gray"},
{name:"Agatha", lastName: "Orange"}
];
// blueprint.cast(Blueprint, object_or_list_of_objects)
var listOfUsers = blueprint.cast(User, listOfObjects);
console.log(listOfUsers[1].get("fullName")); // Mary Red
init
methodvar Car = blueprint({
init: function () {
this.set("model", "BMW"); // It will replace the default model
},
model: "Mercedes Benz"
});
// The object is created and the "init()" method is called
var car = new Car();
console.log(car.get("model")); // BMW
// Just require the package and you are set
var blueprint = require("blueprint");
var Car = blueprint({
// Using closure and IIFE to create the isExpensive method
isExpensive: (function (){
"use strict";
// "Static" list of expensive brands
var expensiveBrands = {
bmw: true,
mercedez: true
};
// The function that will be executed when the
// isExpensive method is called
return function () {
if (expensiveBrands[this.get("brand")]) {
return true;
}
return false;
};
}())
});
var car = new Car({brand:"bmw"});
console.log("Is the car expensive? " + car.get("isExpensive"));
// outputs: Is the car expensive? true
That's it. Any feedback will be appreciated.
