Angular service to read, set and delete browser cookies. Originally based on

the [ng2-cookies](https://www.npmjs.com/package/ng2-cookies) library. This service is lightweight, and its bundle size is **1.3 Kb** to ensure fast loading times and optimal performance.

## Installation

```bash

npm i ngx-cookie-service

# or

yarn add ngx-cookie-service

```

## Demo

https://stackblitz.com/~/github.com/pavankjadda/ngx-cookie-service-demo

## Usage

1. In standalone components, import the CookieService directly into the component

   ```typescript

   import { CookieService } from 'ngx-cookie-service';

   import { Component } from '@angular/core';

   @Component({

     selector: 'my-component',

     template: `
Hello World`,

     providers: [CookieService],

   })

   export class HelloComponent {

     constructor(private cookieService: CookieService) {

       this.cookieService.set('token', 'Hello World');

       console.log(this.cookieService.get('token'));

     }

   }

   ```

2. You can also use `inject()` method in v14+ to inject the service into the component

   ```typescript

   import { CookieService } from 'ngx-cookie-service';

   import { Component, inject } from '@angular/core';

   @Component({

     selector: 'my-component',

     template: `
Hello World`,

     providers: [CookieService],

   })

   export class HelloComponent {

     cookieService = inject(CookieService);

     constructor() {

       this.cookieService.set('token', 'Hello World');

       console.log(this.cookieService.get('token'));

     }

   }

   ```

## Server Side Rendering

Ngx Cookie Service supports Server Side Rendering (SSR) via dedicated

library [ngx-cookie-service-ssr](https://www.npmjs.com/package/ngx-cookie-service-ssr).

Only install `ngx-cookie-service-ssr` library (and skip `ngx-cookie-service`) for SSR

1. Install the library using below command

   ```shell

       npm install ngx-cookie-service-ssr --save

       # or

       yarn add ngx-cookie-service-ssr

   ```

2. By default, browser cookies are not

   available in SSR because `document` object is not available. To overcome this, navigate to `server.ts` file in your

   SSR

   project, and replace the following code

   

   ```typescript

   server.get('*', (req, res) => {

     res.render(indexHtml, { req, providers: [{ provide: APP_BASE_HREF, useValue: req.baseUrl }] });

   });

   ```

with this

```typescript

import { REQUEST as SSR_REQUEST } from "ngx-cookie-service-ssr";

server.get('*', (req, res) => {

  res.render(indexHtml, {

    req,

    providers: [

      { provide: APP_BASE_HREF, useValue: req.baseUrl },

      { provide: SSR_REQUEST, useValue: req },

      { provide: 'RESPONSE', useValue: res },

    ],

  });

});

```

3. This will make sure the cookies are available in `REQUEST` object, and the `ngx-cookie-service-ssr` can

   use `REQUEST.cookies` to access the

   cookies in SSR. Then proceed to use `ngx-cookie-service` as usual.

4. See the [sample repo](https://github.com/pavankjadda/angular-ssr-docker) for more details.

## Supported Versions

We follow angular [LTS versions](https://angular.dev/reference/versions#actively-supported-versions). The latest version of the library supports Angular 17.x.x. Angular 14.x.x or below is not supported.

| Angular Version        | Supported Version |

|------------------------|-------------------|

| 17.x.x                 | 17.x.x            |

| 16.x.x                 | 16.x.x            |

| 15.x.x                 | 15.x.x            |

# API

## check( name: string ): boolean;

```typescript

const cookieExists: boolean = cookieService.check('test');

```

Checks if a cookie with the given`name` can be accessed or found.

## get( name: string ): string;

```typescript

const value: string = cookieService.get('test');

```

Gets the value of the cookie with the specified `name`.

## getAll(): {};

```typescript

const allCookies: {} = cookieService.getAll();

```

Returns a map of key-value pairs for cookies that can be accessed.

## set( name: string, value: string, expires?: number | Date, path?: string, domain?: string, secure?: boolean, sameSite?: 'Lax' | 'Strict' | 'None' ): void;

## set( name: string, value: string, options?: { expires?: number | Date, path?: string, domain?: string, secure?: boolean, sameSite?: 'Lax' | 'None' | 'Strict'}): void;

```typescript

cookieService.set('test', 'Hello World');

cookieService.set('test', 'Hello World', { expires: 2, sameSite: 'Lax' });

```

Sets a cookie with the specified `name` and `value`. It is good practice to specify a path. If you are unsure about the

path value, use `'/'`. If no path or domain is explicitly defined, the current location is assumed. `sameSite` defaults

to `Lax`.

**Important:** For security reasons, it is not possible to define cookies for other domains. Browsers do not allow this.

answer for a more in-depth explanation.

**Important:** Browsers do not accept cookies flagged sameSite = 'None' if secure flag isn't set as well. CookieService

will override the secure flag to true if sameSite='None'.

## delete( name: string, path?: string, domain?: string, secure?: boolean, sameSite: 'Lax' | 'None' | 'Strict' = 'Lax'): void;

```typescript

cookieService.delete('test');

```

Deletes a cookie with the specified `name`. It is best practice to always define a path. If you are unsure about the

path value, use `'/'`.

**Important:** For security reasons, it is not possible to delete cookies for other domains. Browsers do not allow this.

Read [this](https://stackoverflow.com/a/1063760) and [this](https://stackoverflow.com/a/17777005/1007003) StackOverflow

answer for a more in-depth explanation.

## deleteAll( path?: string, domain?: string, secure?: boolean, sameSite: 'Lax' | 'None' | 'Strict' = 'Lax' ): void;

```typescript

cookieService.deleteAll();

```

Deletes all cookies that can currently be accessed. It is best practice to always define a path. If you are unsure about

the path value, use `'/'`.

# FAQ

## General tips

Checking out the following resources usually solves most of the problems people seem to have with this cookie service:

- [article about cookies in general @MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies) (recommended read!)

- [common localhost problems @StackOverflow](https://stackoverflow.com/questions/1134290/cookies-on-localhost-with-explicit-domain)

- [problems with secure cookies @StackOverflow](https://stackoverflow.com/questions/8064318/how-to-read-a-secure-cookie-using-javascript)

- [how do browser cookie domains work? @StackOverflow](https://stackoverflow.com/questions/1062963/how-do-browser-cookie-domains-work)

- [get cookies from different paths](https://github.com/7leads/ngx-cookie-service/issues/7#issuecomment-351321518)

The following general steps are usually very helpful when debugging problems with this cookie service or cookies in

general:

- check out if there are any [open](https://github.com/stevermeister/ngx-cookie-service/issues)

  or [closed](https://github.com/stevermeister/ngx-cookie-service/issues?q=is%3Aissue+is%3Aclosed) issues that answer

  your question

- check out the actual value(s) of `document.cookie`

- does it work if you use `document.cookie` manually (i.e. in a console of your choice)?

- set explicit paths for your cookies

- [explain to your local rubber duck why your code should work and why it (probably) does not](https://en.wikipedia.org/wiki/Rubber_duck_debugging)

# I am always getting a "token missing" or "no provider" error.

Package managers are a well known source of frustration. If you have "token missing" or "no provider" errors, a simple

re-installation of your node modules might suffice:

```

rm -rf node_modules

yarn # or `npm install`

```

## I have a problem with framework X or library Y. What can I do?

Please be aware that we cannot help you with problems that are out of scope. For example, we cannot debug a Symfony or

Springboot application for you. In that case, you are better off asking the nice folks over

at [StackOverflow](https://stackoverflow.com/) for help.

## Do you support Angular Universal?

There is an [issue](https://github.com/7leads/ngx-cookie-service/issues/1) for that. Check

out [this comment](https://github.com/7leads/ngx-cookie-service/issues/1#issuecomment-361150174) for more information

about future support.

# Opening issues

# Contributing

We are happy to accept pull requests or test cases for things that do not work. Feel free to submit one of those.

However, we will only accept pull requests that pass all tests and include some new ones (as long as it makes sense to

add them, of course).

# Author

This cookie service is brought to you by [7leads GmbH](http://www.7leads.org/). We built it for one of our apps, because

the other cookie packages we found were either not designed "the Angular way" or caused trouble during AOT compilation.
