Package Exports

@lopatnov/namespace

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@lopatnov/namespace) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

TypeScript and JavaScript samples

namespace creation

const ns = new Namespace(); // <-- create namespace variable

ns.namespace("a.b.c.d"); // <-- create inner namespaces
ns.namespace("a.b.c.e"); // <-- Function namespace(path: NamespacePath): Namespace
ns.namespace("a.b.f.g"); // <--
ns.namespace("a.i.h.k"); // <--
ns.namespace("a.i.h.l"); // <--
ns.namespace("a.m.n.o"); // <--

// Access to inner namespaces
const anyNS: any = ns; // <-- to avoid type casting
console.log(anyNS.a.b.f.g instanceof Namespace); // true
console.log((ns as any).a.b.c.d instanceof Namespace); // true
console.log((ns as any).a.b.c.e instanceof Namespace); // true

attach namespace to a current object

let shapes = {
    color: "green",
    count: 3
};
let shapesSpace = Namespace.attach(shapes);

shapesSpace.namespace('Triangles');
shapesSpace.namespace('Circles');
shapesSpace.namespace('Rectangles.Squares');

console.log(shapesSpace.exists('Triangles')); // true
console.log(shapesSpace.exists('Circles')); // true
console.log(shapesSpace.exists('Rectangles.Squares')); // true
console.log(shapesSpace.color); // "green"
console.log(shapesSpace.count); // 3
console.log(shapes === shapesSpace); // true

checking that object inside namespace exists

// Function exists(path: NamespacePath): boolean
console.log(ns.exists('a.b.c.d')); // true
console.log(ns.exists('a.b.c.e')); // true
console.log(ns.exists('a.b.f.g')); // true
console.log(ns.exists('a.i.h.k')); // true
console.log(ns.exists('a.i.h.l')); // true
console.log(ns.exists('a.m.n.o')); // true

create namespace through direct call

var dynamicNamespace: any = Namespace; // <-- escape current TypeScript restrictions with any Type
var a = dynamicNamespace('Pacific.Ocean'); // <-- call as function
console.log(a.Pacific.Ocean instanceof Namespace); // true

create namespace through new operator

var n: any = new Namespace("Hello.World");
console.log(n.Hello.World instanceof Namespace); // true

var eeny: any = new Namespace('meeny.miny.moe[Catch][a][tiger][by][the][toe]');
console.log(eeny.meeny.miny.moe.Catch.a.tiger.by.the.toe instanceof Namespace);  // true

go to inner object

var kitchenRadar = new Namespace();
    kitchenRadar.namespace('big.fruits');
    kitchenRadar.namespace('big.eggs');
    kitchenRadar.namespace('small.dishes');
    kitchenRadar.namespace('small.cookies');

    var fruits = kitchenRadar.goto('big.fruits'); // <-- goto(path: NamespacePath): any
    var eggs = kitchenRadar.goto('big.eggs');
    var dishes = kitchenRadar.goto('small.dishes');
    var cookies = kitchenRadar.goto('small.cookies');

    console.log(fruits === (kitchenRadar as any).big.fruits); // true
    console.log(eggs === (kitchenRadar as any).big.eggs); // true
    console.log(dishes === (kitchenRadar as any).small.dishes); // true
    console.log(cookies === (kitchenRadar as any).small.cookies); // true

apply namespace as a property of an object

var persons: any = {};
var extension = new Namespace('with.small.kitty');

extension.applyTo(persons, 'Julia'); // Function applyTo(context: any, name: string): void
extension.applyTo(persons, 'Kathy');
extension.applyTo(persons, 'Liza');

console.log(persons.Julia.with.small.kitty instanceof Namespace); // true
console.log(persons.Kathy.with.small.kitty instanceof Namespace); // true
console.log(persons.Liza.with.small.kitty instanceof Namespace); // true
