    is-webview

    JavaScript WebView detection for Node and the browser.

    Sometimes you need to know if a DOM document or an HTTP request is performed by a UIWebView/WebView or not. Especially to serve a more contextualised experience or to dynamically load components.

    WebView detection is twofold:

    • Browser features and properties;
    • User-Agent sniffing.

    Install

    npm install --save is-webview

    The library is browserify and webpack friendly. Use them!

    Usage in Node

    var iswebview = require('is-webview');
     
    module.exports = function(req, res, next){
      if (iswebview(req.headers['User-Agent'])) {
        // set-up whatever is needed for a WebView
        // ...
        next();
      }
    };

    Usage in the browser

    if (isWebview(navigator.userAgent)) {
      // do whatever is needed for a WebView display
      // ...
    };

    API

    iswebview(userAgent)

    • userAgent (String): Browser User-Agent header string

    Detects a WebView from browser properties (if available) and from a User-Agent string.

    if (iswebview(navigator.userAgent)) {
      // ...
    }

    iswebview(userAgent, configObject)

    • userAgent (String): Browser User-Agent header string
    • configObject (Object): see below.

    Detects a WebView from a custom User-Agent string, browser properties (if available) and fallbacks to regular User-Agent string.

    if (iswebview(navigator.userAgent, { appName: 'FooBar' })) {
      // ...
    }

    configObject

    A configuration object conveys cues to assist the detection:

    • appName (String): the app name explicitly set in your WebView properties/settings.
