So, I took a few hours to go through and make it work with Closure, and then to make it work compiled outside of Closure in case anyone else wants a smaller version of FABridge. I’m calling the result FABridgeC, and you can read more about it on the project’s GitHub page. For most users, this is a minified FABridge.js (or if you prefer Closure’s terminology, a compiled FABridge.js) in just 5.4 KiB that can be dropped in instead of FABridge.js, and should work in exactly the same manner as the original for almost everyone. (There are a few minor caveats explained on the project page.) If you’re using FABridge at the moment, try dropping it in place of your existing FABridge.js, and let me know how it goes!
Feel free to send me a message via GitHub (I’m aschmitz, the repository’s owner) or leave a comment here with any questions, problems, or other comments.
