JSLogger for TYPO3. Log errors and exceptions users are encountering in the frontend to the TYPO3 backend.

What does it do?

This extension simply logs any javascript errors encountered in your frontend via ajax to the TYPO3 backend. It does this by using the PSR\Log\LoggerInterface, so error logs are automatically sent to the Logger that is configured in your TYPO3 instance. (like FileWriter or SysLogWriter)

Logged info:

• Error message
• Stack trace (file name, function, line number, column number, ...)
• Url
• User Agent

This extension uses stacktrace.js for creating readable stacktraces and parsing source maps. This means, that if you use minified js in production and have source maps configured, your logged error stacktrace will automatically show the correct line and column numbers from the unminified file, briefly worded: readable error output.

You can find out more about source maps and how to use them in your javascript here: How_to u se_a_source_map
