Get Started

Installation

You can install this package locally with npm.

# To get the latest stable version and update package.json file:
npm install angular2-cookie --save

After installing the library, it should be included in the SystemJS configurations.

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 * Taken from: https://github.com/angular/quickstart/blob/master/systemjs.config.js
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',

      // angular bundles

Usage

CookieService class is an injectable service with angular @Injectable() decorator. Therefore, it needs to be registered in the providers array (encouraged way). Then, it will be available in the constructor of the component class.

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { CookieService } from 'angular2-cookie/services/cookies.service';

import { AppComponent }  from './app.component';

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ AppComponent ],
  providers: [ CookieService ],
  bootstrap: [ AppComponent ]
})
export class AppModule { }

import {Component} from 'angular2/core';
import {CookieService} from 'angular2-cookie/core';

@Component({
    selector: 'my-very-cool-app',
    template: '<h1>My Angular2 App with Cookies</h1>'
})

export class AppComponent {
  constructor(private _cookieService:CookieService){}

  getCookie(key: string){
    return this._cookieService.get(key);
  }
}

Examples

Here you can find some usage examples with popular boilerplate libraries.

Angular2-quickstart

A boilerplate provided by Angular team. (Link: https://github.com/angular/quickstart)

Just edit the systemjs.config.js file and add the angular2-cookie there.

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',

      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

      // other libraries
      'rxjs':                       'npm:rxjs',
      'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
      'angular2-cookie':            'npm:angular2-cookie'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      },
      'angular2-in-memory-web-api': {
        main: './index.js',
        defaultExtension: 'js'
      },
      'angular2-cookie': {
        main: './core.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

Angular2-seed

A popular seed project. (Link: https://github.com/mgechev/angular2-seed)

Add the following settings to the (constructor of) ProjectConfig class (path: ./tools/config/project.config.ts).

/* Add to or override NPM module configurations: */
//this.mergeObject( this.PLUGIN_CONFIGS['browser-sync'], { ghostMode: false } );
this.mergeObject(this.SYSTEM_CONFIG_DEV['paths'], {'angular2-cookie': 'node_modules/angular2-cookie/bundles/angular2-cookie.js'});
this.mergeObject(this.SYSTEM_BUILDER_CONFIG['packages'], {
  'angular2-cookie': {
    main: 'core.js',
    defaultExtension: 'js'
  }
});

Do not forget to inject the service in the module (providers array).

Angular-cli

A CLI tool for Angular2. (Link: https://github.com/angular/angular-cli)

Edit the vendorNpmFiles array (path: ./angular-cli-build.js).

// Angular-CLI build configuration
// This file lists all the node_modules files that will be used in a build
// Also see https://github.com/angular/angular-cli/wiki/3rd-party-libs

/* global require, module */

var Angular2App = require('angular-cli/lib/broccoli/angular2-app');

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      'systemjs/dist/system-polyfills.js',
      'systemjs/dist/system.src.js',
      'zone.js/dist/**/*.+(js|js.map)',
      'es6-shim/es6-shim.js',
      'reflect-metadata/**/*.+(ts|js|js.map)',
      'rxjs/**/*.+(js|js.map)',
      '@angular/**/*.+(js|js.map)',
      'angular2-cookie/**/*.+(js|js.map)'
    ]
  });
};

Also add angular2-cookie to the map and packages object in the system-config.ts (path: ./src/system-config.ts)

/***********************************************************************************************
 * User Configuration.
 **********************************************************************************************/
/** Map relative paths to URLs. */
const map: any = {
  'angular2-cookie': 'vendor/angular2-cookie'
};

/** User packages configuration. */
const packages: any = {
  'angular2-cookie': {main: 'core.js', defaultExtension: 'js'},
};

CookieService

There are 7 methods available in the CookieService (6 standard methods from Angular 1 and 1 extra removeAll() method for convenience)

get()

Returns the value of given cookie key.

/**
 * @param {string} key Id to use for lookup.
 * @returns {string} Raw cookie value.
 */
get(key: string): string;

getObject()

Returns the deserialized value of given cookie key.

/**
 * @param {string} key Id to use for lookup.
 * @returns {Object} Deserialized cookie value.
 */
getObject(key: string): Object;

getAll()

Returns a key value object with all the cookies.

/**
 * @returns {Object} All cookies
 */
getAll(): any;

put()

Sets a value for given cookie key.

/**
 * @param {string} key Id for the `value`.
 * @param {string} value Raw value to be stored.
 * @param {CookieOptionsArgs} options (Optional) Options object.
 */
put(key: string, value: string, options?: CookieOptionsArgs): void;

putObject()

Serializes and sets a value for given cookie key.

/**
 * @param {string} key Id for the `value`.
 * @param {Object} value Value to be stored.
 * @param {CookieOptionsArgs} options (Optional) Options object.
 */
putObject(key: string, value: Object, options?: CookieOptionsArgs): void;

remove()

Remove given cookie.

/**
 * @param {string} key Id of the key-value pair to delete.
 * @param {CookieOptionsArgs} options (Optional) Options object.
 */
remove(key: string, options?: CookieOptionsArgs): void;

removeAll()

Remove all cookies.

/**
 */
removeAll(): void;

Options

Options object should be a type of CookieOptionsArgs interface. The object may have following properties:

• path - {string} - The cookie will be available only for this path and its sub-paths. By default, this is the URL that appears in your <base> tag.
• domain - {string} - The cookie will be available only for this domain and its sub-domains. For security reasons the user agent will not accept the cookie if the current domain is not a sub-domain of this domain or equal to it.
• expires - {string|Date} - String of the form "Wdy, DD Mon YYYY HH:MM:SS GMT" or a Date object indicating the exact date/time this cookie will expire.
• secure - {boolean} - If true, then the cookie will only be available through a secured connection.

Overriding default options globally

CookieService can use ANGULAR2_COOKIES_PROVIDERS to provide default options. Thus the default options can be altered by overriding the necessary class. See Angular dependency injection guide for more information on the topic.

import {provide} from 'angular2/core';
import {bootstrap} from 'angular2/platform/browser';
import {App} from './myapp';

class MyOptions extends BaseCookieOptions {
  path: string = '/my/path/';
}

bootstrap(App, [ANGULAR2_COOKIES_PROVIDERS, provide(CookieOptions, {useClass: MyOptions})]);

Note

The build process and the file structure of this repository has respectively modeled after the awesome angular2-google-maps project of Sebastian Müller.
