Security

node-webkit adds Node.js support and enhancement in DOM for trusted code and content. For untrusted code and content, it should remain in a normal frame or iframe, which is the same as the one in browser. So there are 2 kinds of frames in node-webkit: Node frame and normal frame.

As application developer, one should be keep in mind that contents should be loaded in correct frames.

Which frames are Node frames and which are not?

1. iframes has the attribute nwdisable are normal frames. (NOTE: nwfaketop attribute should be specified with nwdisable. The reason is in https://github.com/rogerwang/node-webkit/issues/534)
2. Local files (or remote sites when URL matches the node-remote field) are Node frames. (nodejs field should not be set to false in this case)
3. Frames opened with window.open are normal frames when these flags are set: new-instance = true and nodejs = false

What can Node frames do?

1. Node support: access to require, global, process, Buffer and root from Node.
2. Universal access to other frames: this can get around all cross-domain security checks defined in DOM.
3. Ignore X-Frame-Options headers for child frames.

nwdisable is added in 0.5.0 rc2; nwfaketop is added in 0.5.1
