does Javascript class still work

Implement the functionality in PHP, you can't emulate a browser/run javascript with PHP*.

Well, I was thinking about this last night. I have instructions to have a chrome extension create a message path to my CI program in the Google docs and send messages back and forth. The current  issue is that i don't know how to create a message pipe from php to the extension.

So now I am thinking I should have a timer in the extension's background task that tries to open a pipe  to the CI app every say 5 seconds. If the pipe is successful, then, I will change the extension's icon to a camera. If it is not successful, then the extension will work as it does now.

I am using the modified extension as a way to screenscrape a browser tab and store the result to a jpg. I will  transfer the jpg up to my server and then to amazon S3, for further processing with a natural language processor, at a later time. What would  be even better is to have the extension transfer the jpg directly up to s3, but I don't want to bite off more than I can chew!

So, if I do it this way, from the extension (in javascript) to the CI app, it might work. At least I have a chance. But I am also having trouble opening the pipe on my linux client. Worked fine under Windows. I currently get an oauthe2 error. Additionally my server is now running in Docker.

Bottom line I am not sure it is possible to create the path in the other direction.
