PERFORMANCES

Description

A simple wrapper for Performance API

Usage

Basic usage is:

1. Import the library from 'performances'

• import Performances from 'performances';

2. Instantiate the Performances object providing the window.performance object (optional) and invoke the method you want to use on it

• var perf = new Performances(window.performance);
• perf.getTotalTime(time => /* do stuffs with time */);

3. You can use also the asJson method to get all info together:

• perf.asJson(timeData => /*do stuffs with timeData*/)
• The method will provide an object with networkLatency, pageLoad and totalTime keys

Additionaly you can import single methods to have a lower impact on your bundle size:

1. Import single methods you want to use

• import getTotalTime from 'performances/lib/getTotalTime';

2. Call the method providing the callback to call on retrieve

• getTotalTime(time => /*do stuffs with time*/);

Note: using the single methods implies a compilation of the imported code.

Available methods

• getPageLoad
• getNetworkLatency
• getTotalTime
