JS Cookie Examples


//create a cookie named company with valued TLDevTecch
Cookies.set('company', 'TLDevTech');
//create a cookie that expires 7 days from the day it is created
Cookies.set('company', 'TLDevTech', { expires: 7 });
//create a cookie that has effect on current page
Cookies.set('company', 'TLDevTech', { expires: 7, path: '' });

//create a cookie valid to a domain
Cookies.set('name', 'value', { domain: '' });
//create a cookie if its transmission requires a https
Cookies.set('name', 'value', { secure: true });

//get value of a cookie
//get all cookies
//delete a cookie
//delete a cookie valid to the path of the current page
Cookies.remove('company', { path: '' }); //path parameter must be included


The library provides simple JSON storage for cookies. You can pass an Array or Object Literal when creating a cookie, the library will store data like JSON.stringify does.

//create a cookie
Cookies.set('user', { name: 'Peter', age: '12' });
//using get to read data will return a string
Cookies.get('user'); // => '{ "name": "Peter", "age": "12" }'
//using getJSON to read data will return a JSON string like JSON.parse does
Cookies.getJSON('user'); // => { name: 'Peter', age: '12' }
