Fozzie Bear

JavaScript logging and error-logging component for the Just Eat Fozzie UI Component Library.


npm version

This component is designed to catch client-side errors and allow client-side logging which will report back via web server logs.

Logging

  • Allows logging points to be placed in the code

Error logging

  • Allows error logging points to be placed in the client-side JavaScript code
  • Hooks onto window.onerror to catch unhandled exceptions
  • Passes error message to a file on the web server as a querystring parameter, which can then be parsed via web server log parsers

Logging utils

Debugger

  • Sets a debug flag in the client
  • Returns debug info to the client
  • Allows debug mode to be persisted through a cookie

Outputter

  • Using debug mode, optionally outputs the logging messages to the console
  • For client platforms that do not support console, provides output to the browser window
