# 설치 가이드

1. 코드 내려받기

git clone https://github.com/axemclion/browser-perf

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd browser-perf

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

npm start

개발/실행 서버를 켭니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

# browser-perf

- Is a NodeJS based tool
- For measuring browser performance metrics (like frame rates, expensive layouts, paints, styles, etc.) 
- For Web pages, Cordova/Phonegap and other Hybrid applications. 
- Metrics are measured while mimicking real user interactions - clicking buttons, typing content, etc.  
- Tool collects the metrics from sources like `about:tracing`, Chrome Devtools timeline, IE UI Responsiveness tab, Xperf, etc. 
- Monitor this information regularly by integrating the tool with continuous integration systems.

## Documentation 
Read more on [why browser-perf here](https://github.com/axemclion/browser-perf/wiki#why-browser-perf-).

Please see the [wiki pages](https://github.com/axemclion/browser-perf/wiki/_pages) for more information. 
You can find information about supported browsers, [getting started](https://github.com/axemclion/browser-perf/wiki/Setup-Instructions), [command line usage](https://github.com/axemclion/browser-perf/wiki/Command-Line-Usage), reference for the [Node API](https://github.com/axemclion/browser-perf/wiki/Node-Module---API) etc.

## Usage

### Command line

Install the tool using `npm install -g browser-perf` and then run

```
$ browser-perf http://yourwebsite.com --browsers=chrome,firefox --selenium=ondemand.saucelabs.com --username=username --accesskey=accesskey
```

- Replace username and access key with the [saucelabs.com](http://saucelabs.com) username and accesskey
- If you have [Selenium](http://www.seleniumhq.org/download/) set up, you could substitute `ondemand.saucelabs.com` with `localhost:4444/wd/hub`
- You can also use [BrowserStack](http://browserstack.com) credentials and substitute `ondemand.saucelabs.com` with `hub.browserstack.com`

See the [wiki page](https://github.com/axemclion/browser-perf/wiki/Command-Line-Usage) for an extensive list of command line options and more usage scenarios.

Here is a video of the command line usage

## Node Module

browser-perf is also a node module and has the following API

```javascript

var browserPerf = require('browser-perf');
browserPerf('/*URL of the page to be tested*/', function(err, res) {
	// res - array of objects. Metrics for this URL
	if (err) {
		console.log('ERROR: ' + err);
	} else {
		console.log(res);
	}
}, {
	selenium: 'http://localhost:4444/wd/hub',
	browsers: ['chrome', 'firefox']
	username: SAUCE_USERNAME // if running tests on the cloud  
});

```
See the [API wiki page](https://github.com/axemclion/browser-perf/wiki/Node-Module---API) for more details on configuring. 
Instructions on using it for Cordova apps is also on the [wiki](https://github.com/axemclion/browser-perf/wiki/Setup-Instructions#wiki-cordova-applications)

## Scenario
- Websites can become slow
  - over time as more CSS and Javascript is added
  - due to a single commit that adds expensive CSS (like gradients) 
- We use tools in [Chrome](https://developers.google.com/chrome-developer-tools/docs/timeline) or [Internet Explorer](http://msdn.microsoft.com/en-us/library/ie/dn255009%28v=vs.85%29.asp) only when the site is too slow. 
- Tools like YSlow and Page Speed are great, but will it not be better if the are a part of continuous integration?
- Tools like this(http://npmjs.org/package/browser-perf) and [Phantomas](https://github.com/macbre/phantomas) can fill the gap to monitor site performance every time a checkin is performed.
