These days I spent some time working on Yez!. Chrome extension whose main role is to replace the annoying switching between the terminal and the browser. It uses Node.js module to run shell commands. So, I had to deal with child processes, and I decided to document my experience.

I'm currently working on a Google Chrome extension and I need to run a JavaScript in the context of the current page. The obvious choice for such a logic is the content script. However it is not so easy, because the content script has an access only to the DOM of the current page. It can't run global functions or use global objects.
