Completely new API and lots of treats

Sorry about that, but trust me, it's totally worth it.

• Simpler API 🦋
• Browser information for reference 💁‍♂️ like connection and memory
• More metrics ♥️ such as assets count, size and timing, DOM node count and depth and more

[FIX] bundle in es5

1.2.2

fix bundle (es5), add check (#12)

Add measure function

measure

Wrap a function and measure it's execution time in milliseconds into a performance measure entry.

import { measure } from 'page-timing';
await pageTiming.measure(wait, 'my-function');

// Example: Convert entries to a named array
performance.getEntriesByType('measure').reduce(
  (accumulator, {name, duration}) => Object.assign(accumulator, {[name]: duration}),
  {}
);
// {my-function: 53.35999990347773}

// Example: Retrieve a specific entry
const { duration } = performance.getEntriesByType('measure')
  .find(({name}) => name === 'my-function');
// 53.35999990347773

Add paint events

• Add paint entries "first-paint" and "first-contentful-paint" (see full list below)

• Add experimentation page (npm start)

• Adjust dist to be ES5 compatible (babel)

Create a fallback for systems where WeakMap is not available

Removed internal memoisation mechanism when weakmap is not available

Improve performance of default metrics used

Skip metrics filtering when using default list
