Save the console.log in Chrome to a file

Solution 1:

Good news

Chrome dev tools now allows you to save the console output to a file natively

1. Open the console
2. Right-click
3. Select "save as.."

Chrome Developer instructions here.

Solution 2:

I needed to do the same thing and this is the solution I found:

1. Enable logging from the command line using the flags:

   --enable-logging --v=1

This logs everything Chrome does internally, but it also logs all the console.log() messages as well. The log file is called chrome_debug.log and is located in the User Data Directory which can be overridden by supplying --user-data-dir=PATH (more info here).

2. Filter the log file you get for lines with CONSOLE(\d+).

Note that console logs do not appear with --incognito.
