js-performance

A simple javascript utility to measure performance

Reason

Using console.time and console.timeEnd is tedious and may introduce extra time by invoking console.

Usage

• time to mark the start point
• timeEnd to mark the end point
• log to log all mark message together
• block to block js thread

import {time, timeEnd, log, block} from 'js-performance'

time('test')
block(5000)
timeEnd('test')

log() // test: 5000ms

• measureCRP to measure the CRP time including interactive, domContentLoaded and complete

import {measureCRP} from 'js-performance'

measureCRP() // log your CRP time
