Unzip into your web project and reference from your HTML like this:

<script src="zappar-mobileonly.js"></script>

CDN

Reference the zappar-mobileonly.js library from your HTML like this:

<script src="https://libs.zappar.com/zappar-mobile-only/0.0.2/zappar-mobileonly.js"></script>

NPM Webpack Package

Run the following NPM command inside your project directory:

$ npm install --save @zappar/mobile-only

Then import the library into your JavaScript or TypeScript files:

import * as MobileOnly from "@zappar/mobile-only";

Usage

Detecting Browsers

The MobileOnly.isMobile() function returns true if a mobile browser is being used.

import * as MobileOnly from "@zappar/mobile-only";
const mobile = MobileOnly.isMobile(); // boolean
console.log(mobile);

User agent can be provided to the isMobile() function, if not specified, navigator.userAgent is used:

import * as MobileOnly from "@zappar/mobile-only";
const mobile = MobileOnly.isMobile('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36');
console.log(mobile);

Displaying the UI

The QR code shown is generated from the current window.location.href.

Default

You can show the redirection UI using MobileOnly.showUI(). This should be used alongside MobileOnly.isMobile():

import * as MobileOnly from "@zappar/mobile-only";

if (!MobileOnly.isMobile()){
  MobileOnly.showUI();
}

The showUI function appends the elements as children of document.body, with z-index of 10000.

Customization

showUI() function may be customized using an options parameter. Here's the available options alongside default values:

type Options = {
    header? : string,       // 'Almost there...';
    instructions? : string, // "Use your phone's camera to scan the QR code below";
    footer? : string,       // 'or visit';
    url? : string           //  window?.location?.href || '0.0.0.0';
}

Example:

import * as MobileOnly from "@zappar/mobile-only";

if (!MobileOnly.isMobile()){
  MobileOnly.showUI({
    url : 'www.zappar.com'
  });
}

This shows the UI seen at the top of this readme.
