## Get Started
### Installation
You can install this package locally with npm.
```bash
# To get the latest stable version and update package.json file:
yarn add ngx-cookie
# or
# npm install ngx-cookie --save
```
### Usage
`CookieModule` should be registered in angular module with `withOptions()` static method.
These methods accept `CookieOptions` objects as well. Leave it blank for the defaults.
```typescript
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { CookieModule } from 'ngx-cookie';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule, CookieModule.withOptions() ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
```
```typescript
import { Component } from '@angular/core';
import { CookieService } from 'ngx-cookie';
@Component({
selector: 'my-very-cool-app',
template: 'My Angular App with Cookies
'
})
export class AppComponent {
constructor(private cookieService: CookieService){}
getCookie(key: string){
return this.cookieService.get(key);
}
}
```
### Server Side Rendering
`ngx-cookie` supports usage during Server Side Rendering (SSR / Angular Universal). Getting Server Side Rendering itself set up the first time can be tricky and is outside the scope of this guide. Here, we'll assume that you've got a working SSR setup similar to the [Angular Universal Starter project](https://github.com/angular/universal-starter), and you're just trying to get `ngx-cookie` working with SSR.
Note: during normal, client side usage, `ngx-cookie` manipulates the client cookies attached to the `document` object. During SSR, `ngx-cookie` will manipulate cookies in http request or response headers._
#### Setup
Install `ngx-cookie-backend` library:
```shell script
yarn add ngx-cookie-backend
# or
# npm install ngx-cookie-backend --save
```
Then edit `app.server.module.ts` and add `CookieBackendModule.withOptions()` to imports:
```typescript
/* app.server.module.ts */
import { CookieBackendModule } from 'ngx-cookie';
@NgModule({
imports: [
AppModule,
ServerModule,
CookieBackendModule.withOptions()
],
bootstrap: [AppComponent]
})
export class AppServerModule {}
```
Next, we need to make providers for the `'REQUEST'` and `'RESPONSE'` objects created by the expressjs server during SSR. To do this, edit `server.ts` to create providers for `'REQUEST'` AND `'RESPONSE'`.
```typescript
/* server.ts */
// All regular routes use the Universal engine
server.get('*', (req, res) => {
res.render(indexHtml, {
req,
res,
providers: [
{provide: APP_BASE_HREF, useValue: req.baseUrl},
{provide: REQUEST, useValue: req},
{provide: RESPONSE, useValue: res}
]
});
});
```
And that's it! all your application's calls to `CookieService` should now work properly during SSR!
### Examples
Normal usage example is under `projects/test-app`
SSR usage example is under `projects/backend-test-app`
## 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.
```typescript
/**
* @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.
```typescript
/**
* @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.
```typescript
/**
* @returns {Object} All cookies
*/
getAll(): any;
```
### put()
Sets a value for given cookie key.
```typescript
/**
* @param {string} key Id for the `value`.
* @param {string} value Raw value to be stored.
* @param {CookieOptions} options (Optional) Options object.
*/
put(key: string, value: string, options?: CookieOptions): void;
```
### putObject()
Serializes and sets a value for given cookie key.
```typescript
/**
* @param {string} key Id for the `value`.
* @param {Object} value Value to be stored.
* @param {CookieOptions} options (Optional) Options object.
*/
putObject(key: string, value: Object, options?: CookieOptions): void;
```
### remove()
Remove given cookie.
```typescript
/**
* @param {string} key Id of the key-value pair to delete.
* @param {CookieOptions} options (Optional) Options object.
*/
remove(key: string, options?: CookieOptions): void;
```
### removeAll()
Remove all cookies.
```typescript
/**
*/
removeAll(): void;
```
## Options
Options object should be a type of `CookieOptions` 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 `` 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.
- **sameSite** - {"Lax"|"Strict"|"None"} - Designates cookie for first party (Lax|Strict) or third party contexts.
- **httpOnly** - {boolean} - If `true`, then the cookie will be set with the `HttpOnly` flag, and will only be accessible from the remote server. Helps to prevent against XSS attacks.
- **storeUnencoded** - {boolean} - If `true`, then the cookie value will not be encoded and will be stored as provided.
