When using libraries or frameworks you will often have large portions of well-tested third party
code that is unlikely to have caused an error for you. In order to keep the focus on your code
Rollbar will collapse stack frames from third party code.
To set this up all you have to do is configure your SDK to send the
the prefix URL for all in-house stack frame filenames. Any code from outside the
directory will be collapsed by default when you load that item in the Rollbar UI.
For example, in a hypothetical stack trace with lines from the following files:
server.root set to
/home/deploy/www/app, the lines from the
vendor directory would be collapsed together, to allow you to focus on your code, and not the
unlikely possibility that
webfmk has a bug.
Sometimes you'll have split your code into multiple sibling modules adjacent to folders
you do not want included as project code (vendor, models, controllers, for instance). In these cases
you can send additional application roots in the
project_package_paths key. These paths should
look identical to the server root (the beginning of a URL), and the key should be in an array
containing any additional folders to be considered "in-project".
