A React hook to access data from the Ambient Light API.

Installation

Using npm:

npm install --save react-hook-ambient-light

Using yarn:

yarn add react-hook-ambient-light

Usage

import React from 'react'
import useAmbientLightSensor from 'react-hook-ambient-light'

const ComponentWithAccelerometer = () => {
  const sensor = useAmbientLightSensor()

  return !sensor.error ? (
    <ul>
      <li>X: {sensor.x}</li>
      <li>Y: {sensor.y}</li>
      <li>Z: {sensor.z}</li>
    </ul>
  ) : (
    <p>No ambient light, sorry.</p>
  )
}

Using SensorOptions

If you want to use this feature, simply provide useAmbientLightSensor with a SensorOptions object:

const sensor = useAmbientLightSensor({
  frequency: 60, // cycles per second
})

Notes

Access to data from the Ambient Light API needs user permission.

Caveats

Ambient Light API is available only in secure contexts (only using HTTPS).
