linkstash

Save hal-json _link properties and retrieve the latest link in a set. E.g. after multiple calls for new data in a set you keep pointers to the oldest and newest data in your set.

Installation

npm install linkstash

Usage

var linkstash = require('linkstash');

var links = linkstash(function(val) {
  return parseInt(val.split('=')[1]);
});

links.set({
  _previous: 'foo.com?until=10',
  _next: 'foo.com?from=100'
});

links.get();
// => {
//  previous: 'foo.com?until=10',
//  next: 'foo.com?from=100'
// }

links.set({
  _previous: 'foo.com?until=100',
  _next: 'foo.com?from=val=190'
});

links.get()
// => {
//  previous: 'foo.com?until=10',
//  next: 'foo.com?from=190'
// }

API

var links = linkstash()

Create a new linkstash instance. Takes normalize function which normalizes strings to be compared. The function

var linkstash = require('linkstash');

var links = linkstash(function(val) {
  return parseInt(val.splice(10));
});

links.set()

Pass in a new object with a previous and next property (either can have an optional _ prepended). When setting the values will be parsed through the earlier set normalize function and compared. For previous values, the lowest value remains. For next values, the highest value remains.

links({
  previous: 'mysite.com/?until=1234567',
  next: 'mysite.com/?from=7654321'
})

links({
  _previous: 'mysite.com/?until=1234568',
  _next: 'mysite.com/?from=8654321'
})

links.get()

Get the stored links. Values are returned without prepending _.

links.get();
// => {
//   previous: 'mysite.com/?until=1234567',
//   next: 'mysite.com/?from=7654321'
// }
