## Device Detection with WURFL.jsFor example, your current device looks like:"complete_device_name": \<% WURFL.complete_device_name %>,"form_factor": \<% WURFL.form_factor %>In development, you may pass `debug=true` to the query string to disable any caching.WURFL.js is fully compatible with Chromium's User-Agent Client Hints (UA-CH) initiative. If User-Agent Client Hints are absent in the HTTP headers that WURFL.js receives, the service will automatically fall back to using the User-Agent Client Hints' JS API to fetch high entropy client hint values from the client device. However, we recommend that you explicitly opt-in/advertise support for User-Agent Client Hints on your website and delegate them to the WURFL.js service for the fastest detection experience. Our documentation regarding implementing User-Agent Client Hint support is available here.Below are the capabilities included in the free WURFL.js Lite:Concatenation of brand name, model name, and marketing name (where available) of a device into a single string. (Note that the full iPhone model is only available in commercial WURFL.js Basic, Standard, or Pro licenses.)May return any of these values: `Desktop`, `Tablet`, `Smartphone`, `Feature Phone`, `Smart-TV`, `Robot`, `Other non-Mobile`, `Other Mobile`Returns `true` if the device is wireless (e.g., Wi-Fi, 3G, LTE). Specifically, a tablet or mobile phone is considered wireless. Otherwise, a desktop or laptop is `false`.Need a more detailed analysis? WURFL.js Basic, Standard and Pro plans include 24 WURFL device capabilities.Based on this device intelligence, you can build code to support mobile optimization, more targeted and effective advertising, and collect analytics on device capabilities. For example, this current page uses WURFL.js to optimize the UX depending on what type of device you are using to visit it.Desktop devices see a video background on the top of the page.Mobile devices see a background image.What Spider does on wurfl.io
