Deeplinker

This module helps you to create web-links for opening native applications directly if it is possible. Otherwise web page will be opened.

Install

You can install script via package managers or download it to your server.

NPM and Yarn

Install package

npm install @codexteam/deeplinker --save

yarn add @codexteam/deeplinker

Then require deeplinker module

const deeplinker = require('@codexteam/deeplinker');

Local script

Download dist/deeplinker.js file to your server and add it to your webpage.

<script src="dist/deeplinker.js" async></script>

Usage

Let's imagine that you want to create a link that opens some page in application, if it is installed. If target application is missing then link should open a web page as a normal link.

Check out example schemes below.

On click

Firstly you need to add the following params to deeplinker elements:

data-link or href with a usual link
data-app-link with a deep link (with custom protocol) to an application

Set up data-app-link param for links with href.

<a href="https://www.instagram.com/codex_team/" data-app-link="instagram://user?username=codex_team">
  Follow us on Instagram
</a>

Or set up data-link and data-app-link params for any other elements

<div data-link="https://t.me/codex_team" data-app-link="tg://resolve?domain=codex_team">
  Join our Telegram-channel
</div>

Then you need to add click listeners. There are two ways to do this.

Add listeners automatically

Add target class name to all deeplinker elements (deeplinker by default). Use deeplinker.init() function to add listeners automatically to all elements with target class name. event.preventDefault and deeplinker.click will be added as onclick function.

Run this function when page is loaded.

<body onload='deeplinker.init()'>

<div class="deeplinker" data-link="https://t.me/codex_team" data-app-link="tg://resolve?domain=codex_team">
  Join our Telegram-channel
</div>

Custom selector

You can call deeplinker.init() with string param to set up target selector. .deeplinker by default.

Example:

deeplinker.init('.my_deeplinker_element');

for

<div class="my_deeplinker_element" ...>
  Join our Telegram-channel
</div>

Set up onclick functions by yourself

Call deeplinker.click(element) function on click.

Set up click function on deeplinker elements.

<div onclick="deeplinker.click(this)"
     data-link="https://t.me/codex_team"
     data-app-link="tg://resolve?domain=codex_team">Join our Telegram-channel</div>

For link elements you also need to add event.preventDefault function:

<a href="https://www.instagram.com/codex_team/"
   onclick="event.preventDefault(); deeplinker.click(this)"
   data-app-link="instagram://user?username=codex_team">Follow us on Instagram</a>

Try to open app automatically

If you want to try to open app silently then call deeplinker.tryToOpenApp(deepLink).

Could be useful for redirection or invitation pages.

Doesn't work on mobile devices.

<body onload="deeplinker.tryToOpenApp('tg://user?username=codex_team')">
