Installation

yarn add fela-statistics

You may alternatively use npm i --save fela-statistics.

Usage

Adding the statistics enhancer will add a new function to the renderer called getStatistics. You may call it at any given time, to get the current statistics object.

import { createRenderer } from 'fela'
import statistics from 'fela-statistics'

const renderer = createRenderer({
  enhancers: [ statistics() ]
})

// rendering stuff

const stats = renderer.getStatistics()
console.log(stats)
