HarSharp

A small and easy-to-use library to parse HTTP Archive (HAR) format to .NET objects.

---

Introduction

The HTTP Archive (HAR) format as defined in the W3C Specification is an archival format for HTTP transactions that can be used by a web browser to export detailed performance data about web pages it loads.

So, every modern browser nowadays can export HAR with a lot of information about the user navigation. Chrome, for example, can export HAR from Developer Tools, Network tab, right mouse click and "Copy all as HAR".

What I can do with HAR data? Well, there a lot of things I can imagine right now, like:

• Web performance tests runners
• Performance analyzers
• Navigation visualizers

Setup

NuGet

install-package HarSharp

---

Usage

Deserialize from string

var har = HarConvert.Deserialize(harContent);

Deserialize from file

var har = HarConvert.DeserializeFromFile(fileName);

Listing pages load time

var har = HarConvert.Deserialize(harContent);

foreach(var page in har.Log.Pages)
{
	Console.WriteLine(
	"Page: {0} loaded in {1} milliseconds", 
	page.Title, 
	page.PageTimings.OnLoad);
}

Code philosophy

The idea of HarSharp is simplify and promote the use of HAR in .NET codes and keep closest possible to W3C specification , for this reason the below rules were followed during the library development:

• Keep the entities and properties names equals to the one defined in the specification, but follow the C# naming guidelines, so, "pages" became "Pages".
• Keep the properties types closest to the spec, but change when there is a better type on .NET side.
  • string (ISO 8601 - YYYY-MM-DDThh:mm:ss.sTZD): System.DateTime (UTC).
  • string (url): System.Uri.
• Full documentation using citations from W3C specification.
• StyleCop validation.
• FxCop Validation.
• 100% unit test coverage
