This script catches any client-side errors that occur in any modern browser and pass the information – line number, URL, stack trace – to the server for logging. It can provide significant insight into problems occurring on your web sites and applications that otherwise would go missed.
The JS error logger has three parts:
- log.js – a standalone JS script that captures the error and submits the data via Ajax to…
- /server – a number of server-side scripts to store the errors. You only need to pick one. I’ve provided three simple PHP scripts that handle the error in slightly different ways: store them in a MySQL Database table, log them using PHP’s own error_log function and log them in a custom log file. But this list can be expanded to add server-side tracking in whatever language you want. Fork away! Each server-side logger folder contains a separate README providing a little more info.
- /tests – this folder contains some simple tests to confirm errors are being appropriately logged.
