Disable Local Security In Chrome (More Easily)

This is a quick follow up to my previous post about disabling local security errors in Chrome on OSX.

I’ve been working a lot with command files lately and thought I would share a simple one that you can double-click in the Finder to launch Chrome with the -disable-web-security flag set. This lets you test content locally that uses “sandboxed” JS features like accessing the pixel data of local images. Handy when working with EaselJS.

This comes with the obvious warning that you probably shouldn’t surf the web in this mode.

You can download the command here. For it to work properly, you need to quit Chrome prior to running the command. You may also need to open it up in a text editor and change the path to Chrome if it’s somewhere other than /Applications, or you want to use this command with Chrome Canary.

Command files are pretty handy – they let you package Terminal commands into a file that can be double clicked in the Finder. Definitely worth learning about if you’re a developer on OSX. There are also .terminal and .term files, which provide similar functionality with a little more control, but they seem to have some issues in the current version of Terminal.
