About The Project

Cookies are very often used in today's websites and web applications, but handling cookies in plain Javascript can be complicated. With Svelte-Cookie the complicated and complex cookie handling is over.

Here's why:

• With the getCookie function, you can quickly get a cookie from the browser.
• With the setCookie function, you can easily create a new cookie that will be set in the web browser.
• With the deleteCookie function, you can quickly erase an existing cookie from the web browser.

Getting Started

It's very easy to get started with Svelte-Cookie. Follow the instructions below, and you will be working with cookies in no time.

Installation

To install, please write the following in your terminal:

npm install --save svelte-cookie

Usage

To use svelte-cookie, please start by importing the desired functions to your project. As of this moment, svelte-cookie contains 3 functions which are:

• getCookie
• setCookie
• deleteCookie

You can import them by using the following line:

import { getCookie, setCookie, deleteCookie } from 'svelte-cookie';

Examples

Underneath here you will find some examples of ways to use the individual functions:

getCookie: The getCookie function is as the name says, getting a cookie. You do that by providing the name of the cookie. If the cookie exists the value length will be longer than 0.

let co = getCookie('userEmail');

If the userEmail cookie exist, you will get back the value. If it doesn't exist you will get back an empty string.

setCookie: The setCookie allows you to add a cookie to the web browser in only a few steps. The setCookie has some options which you have to provide:

• Name - The first parameter is the name of the cookie.
• Value - The second parameter is the string value you want to cookie to have.
• Expiration days - Provide a number of how many days your cookie should stay in the web browser.
• Secure - Write either true or false depending on whether you want your cookie to have the secure attribute.

setCookie('userEmail', '[email protected]', 30, true);

The above code will create a cookie named "userEmail", with the value "[email protected]". It will expire in 30 days and it will be set as secure.

deleteCookie: The deleteCookie function is very simple, and it will allow you to quickly erase a cookie from the web browser. You simply provide the name of the cookie as shown in the example below:

deleteCookie('userEmail');
