delta-differ v1.0.15

Differ

This package helps sending the HTML content of a page to a remote origin repeatedly. It keeps internal state of the last HTMLs it saw and only sends the delta.

const differ = require('delta-differ');
const diffClient = new differ.DiffClient((ticket) => {
    // this method can return a promise - presumably it would perform 
    // a remote call to another machine running the code - the
    // other machine knows what the state is by the passed ticket parameter
    // see the e2e tests for a full example
    return differ.delta(ticket);
});
const pageHtml = diffClient.sync();
// some time later after html changes...
const newPageHtml = diffClient.sync();

Syncing other things

The delta function accepts a second "getHtml" argument that's useful for getting something other than the page body's html.
