react-wifi-indicator

An easy-to-use wrapper that provides 6 different WiFi icons and a utility to convert raw dBm to signal strength categories.

👉 Demo site and docs.

Quick Start

First, install the module:

npm install react-wifi-indicator --save

Demos

Using the strength prop to set the icon.

import WifiIndicator from 'react-wifi-indicator';
// ...
<WifiIndicator strength='EXCELLENT' />
<WifiIndicator strength='GREAT' />
<WifiIndicator strength='OKAY' />
<WifiIndicator strength='WEAK' />
<WifiIndicator strength='UNUSABLE' />
<WifiIndicator strength='DISCONNECTED' />

Use the Enum

Ideally, you should use the provided enum instead of “magic prop strings.”

import WifiIndicator, { SignalStrength } from 'react-wifi-indicator';
// ...
<WifiIndicator strength={SignalStrength.EXCELLENT} />
<WifiIndicator strength={SignalStrength.GREAT} />
<WifiIndicator strength={SignalStrength.OKAY} />
<WifiIndicator strength={SignalStrength.WEAK} />
<WifiIndicator strength={SignalStrength.UNUSABLE} />
<WifiIndicator strength={SignalStrength.DISCONNECTED} />

dBm?

If you have dBm (decibel-milliwatts) you’ll need a way to calculate the signal strength. You can use the utility DBMToSignalStrength for that.

Import Setup

import WifiIndicator, { DBMToSignalStrength } from 'react-wifi-indicator';

Demos

<WifiIndicator strength={DBMToSignalStrength(-42)} />
<WifiIndicator strength={DBMToSignalStrength(-51)} />
<WifiIndicator strength={DBMToSignalStrength(-62)} />
<WifiIndicator strength={DBMToSignalStrength(-76)} />
<WifiIndicator strength={DBMToSignalStrength(-89)} />
<WifiIndicator strength={DBMToSignalStrength(-100)} />

Your Own Utility?

You can always write your own utility if you don’t like the heuristics of DBMToSignalStrength. Just remember that:

• -30 dBm is the maximum achievable signal strength.
• -42 dBm is an amazing, but realistic signal strength.
• -90 dBm is unusable and approaching or drowning in the noise floor.

Styling and Accessibility

The icon is pretty much an image with an svg as the source. You can pass down alt attributes, styles, classNames, etc.

Accessibility

You can pass an alt tag in order to add semantic meaning to the icons. But if you don’t provide one, the library will default it to an empty string. (Marking it as presentational.)

Custom Styles

<WifiIndicator
  strength={SignalStrength.EXCELLENT}
  alt='Excellent Wifi'
  style={{
    height: 100,
    border: '2px solid cornflowerblue',
    borderRadius: 4,
    padding: 12,
  }}
/>

Custom Icons

Using custom icons might defeat the purpose of the library. But you can totally do it! Provide a prop called statusImages that looks like this:

<WifiIndicator
  statusImages={{
    EXCELLENT: 'some path, data:img, etc.',
    GREAT: 'some path, data:img, etc.',
    OKAY: 'some path, data:img, etc.',
    WEAK: 'some path, data:img, etc.',
    UNUSABLE: 'some path, data:img, etc.',
    DISCONNECTED: 'some path, data:img, etc.',
  }}
/>
