Usage

Parse a Link header:

var li = require('li');
var someLinksHeader = '</api/users?page=0&per_page=2>; rel="first", ' +
                      '</api/users?page=1&per_page=2>; rel="next", ' +
                      '</api/users?page=3&per_page=2>; rel="last"';

console.log(li.parse(someLinksHeader));

// This will print:
// {
//   first: '/api/users?page=0&per_page=2',
//   next: '/api/users?page=1&per_page=2',
//   last: '/api/users?page=3&per_page=2'

var linksObject = {
  first : '/api/users?page=0&per_page=2',
  next  : '/api/users?page=1&per_page=2',
  last  : '/api/users?page=3&per_page=2',
};

console.log(li.stringify(linksObject);

// This will print the string:
// </api/users?page=0&per_page=2>; rel="first",
// </api/users?page=1&per_page=2>; rel="next",
// </api/users?page=3&per_page=2>; rel="last"
