Basic Usage

smartbanner.js works automagically given following meta tags:

<!-- Start SmartBanner configuration -->
<meta name="smartbanner:title" content="Smart Application">
<meta name="smartbanner:author" content="SmartBanner Contributors">
<meta name="smartbanner:price" content="FREE">
<meta name="smartbanner:price-suffix-apple" content=" - On the App Store">
<meta name="smartbanner:price-suffix-google" content=" - In Google Play">
<meta name="smartbanner:icon-apple" content="https://url/to/apple-store-icon.png">
<meta name="smartbanner:icon-google" content="https://url/to/google-play-icon.png">
<meta name="smartbanner:button" content="VIEW">
<meta name="smartbanner:button-url-apple" content="https://ios/application-url">
<meta name="smartbanner:button-url-google" content="https://android/application-url">
<meta name="smartbanner:enabled-platforms" content="android,ios">
<meta name="smartbanner:close-label" content="Close">
<!-- End SmartBanner configuration -->

Additionally, JavaScript and CSS has to be included:

<link rel="stylesheet" href="node_modules/smartbanner.js/dist/smartbanner.min.css">
<script src="node_modules/smartbanner.js/dist/smartbanner.min.js"></script>

Advanced usage

Hide the smartbanner for certain User Agents

There are cases where you do not want to show the smart app banner on all Android and/or all iOS devices. For example:

your app is availabe only for some Android/iOS versions
your app is only availabe on iPhone, but not iPad
your app is a web app which also shows this website, but of course should not show the smart app banner.

In this case you can define a regular expression, which matches all user agent strings that should be excluded. Just add another meta tag like the following:

<meta name="smartbanner:exclude-user-agent-regex" content="^.*My Example Webapp$">

This regular expression would match any user agent string, that ends with My Example Webapp.

Show the smartbanner for certain User Agents

In addition to blacklisting certain user agents using the regex explained in the previous section, you can also whitelist certain user agents:

<meta name="smartbanner:include-user-agent-regex" content="iPhone 7">

Note: You can define enabled-platforms, exclude-user-agent-regex and include-user-agent-regex at the same time. enabled-platforms has the lowest priority, exclude-user-agent-regex the highest priority.

Disable Positioning

If you want to position smart app banner yourself (e.g. in CSS), you can disable built-in positioning with following option:

<meta name="smartbanner:disable-positioning" content="true">

Hide the smartbanner completely

If you want to prevent smartbanner rendering in some html pages, you can add optional meta tag:

<meta name="smartbanner:enabled-platforms" content="none">

Time-limited close

By default smartbanner would not reappear if closed. This can be prevented with hide-ttl option. Following example would keep smartbanner closed for 10 seconds (10000 ms):

<meta name="smartbanner:hide-ttl" content="10000">

Path-designated close

Once closed smartbanner would reappear if site path changes. It is default behaviour.

Following example would keep smartbanner closed site-wide (but only when user has actually closed it):

<meta name="smartbanner:hide-path" content="/">

Custom design modifier

smartbanner uses built-in platform-specific styles (e.g. smartbanner--ios or smartbanner--android), but this behaviour can be altered by adding custom design modifier that allows use of:

externally defined styles, e.g.:
```
  <meta name="smartbanner:custom-design-modifier" content="mysite.com">
```
which would add smartbanner--mysite.com class on wrapper.
forced platform-specific styles on all platforms, e.g.:
```
  <meta name="smartbanner:custom-design-modifier" content="ios">
```
which would add smartbanner--ios class on wrapper regardless of actual platform.

smartbanner API use

By default smartbanner is added to DOM automatically. You can disable it with

<meta name="smartbanner:api" content="true">

and add smartbanner to DOM manually:

smartbanner.publish();

Events

Following events are being dispatched:

Event	Description
`smartbanner.init`	Dispatched when smartbanner has been initialised
`smartbanner.view`	Dispatched when smartbanner is added to display
`smartbanner.clickout`	Dispatched when smartbanner is clicked to navigate to app store
`smartbanner.exit`	Dispatched when smartbanner is closed

Example handler (closes smartbanner when user clicks to navigate to app store):

document.addEventListener('smartbanner.clickout', smartbanner.exit);
