live-proxy

Live reloading for JavaScript + sand boxing.

The purpose of this library is to eventually replace the live reload mechanism used by live-editor.

Demo

Features

Reloading

• only re-initialize objects when the code that initialized them changes
• handles prototype style classes
• handles objects containing cycles
• handles saving/restoring global state in Processing-js in a generalizable way
• handles inheritance

Sand Boxing

• rewrite user code that access window to access a custom window-like object
• prevent introspection of rewritten code by forcing .toString() to return original user code for functions

Error Handling

• all exceptions are caught automatically in all user code including callbacks and event handlers.

TODO

• handle ES2015 style classes
• iframe sand boxing
• proper event handling in iframes
• wrap document.createElement to prevent creation of other iframes or scripts programmatically
• automatically handle cleanup of timers and intervals
