HAR stands for HTTP Archive format. Browsers use this format to export HTTP request and response traces as waterfal diagrams.

This repo contains a jQuery based widget to render HAR data as a waterfall diagram. I wrote this as a lighter embeddable alternative to Jan Odvarko's online HAR Viewer. In additon to supporting full HAR-formatted JSON objects, this alternative can render requests and responses incrementally making it suitable to show the waterfall lines as requests are being made.

This version also uses Steve Souder's draft conventions for connection state.

Try Online

You can try this viewer online. Open http://s3u.github.com/har-view/, and drop a HAR file anywhere in the browser window.

Example

Example

Prerquisites

Include the following to use this widget in a page.

<script type='text/javascript' src='scripts/mustache.js'></script>
<script type='text/javascript' src='scripts/jquery.min.js'></script>
<script type='text/javascript' src='scripts/jquery-ui.min.js'></script>
<script type='text/javascript' src='scripts/har-viewer.js'></script>
<link rel='stylesheet' href='css/jquery-ui.css'/>
<link rel='stylesheet' href='css/har-viewer.css'/>

Then place a div tag to hold the waterfall diagram.

<div id='har-view'></div>

Loading Full HAR Objects

If you have a full HAR object, you can initialize the diagram in one go.

$('#har-view').HarView();
var har = $('#har-view').data('HarView');
har.render(data);

Incremental Initialization

$('#har-vew').HarView();
var har = $('#har').data('HarView');

// Add an entry - use a unique identifier for each request
har.entry(id, {
    startedDateTime: t
});

// Add request data
har.request(id, {
    method: 'GET',
    url: 'http://foo.com/blah',
    headers: [
        {name: 'Connection', value: 'keep-alive'}
        ]
    });

// Add timings
har.timings(id, {
                "blocked": 100,
                "dns": 10,
                "connect": 20,

                "wait": 40,
                "receive": 50
            });

// Add response
har.response(id, {
    "status": 200,
    "bodySize": 8730,
    "headers": [
        {
            "name": "content-type",
