Hi Nick ,
"Form-Based Composer for AP" is on the Adobe Target Future Roadmap However We are not sure of the date / timeline on when it will be available to the Adobe target Users.
Also,The at.js library is a new implementation library for Adobe Target designed for both typical web implementations and single-page applications.
Among other benefits, at.js improves page-load times for web implementations and provides better implementation options for single-page applications.
The at.js library offers several improvements over the mbox.js library, including:
- Completely asynchronous communication via cross domain AJAX
- Important: Although at.js communicates with the Target servers asynchronously, the at.js file itself must load synchronously in the <head> section of your page. Ideally, it should be one of the first scripts loaded. Once loaded, at.js executes mbox calls asynchronously through XMLHttpRequest, and does not block page rendering.
- No more blocking calls
- No document.write() used
- No immediate execution of JavaScript in Target responses
- Better timeout and error handling
- Customizable timeout per call
- No reloads on timeouts
- Functions designed specifically for single-page apps/MVC frameworks
