Logging in JavaScript

The JavaScript^® client library logs messages to the console.

Log levels

Events are logged at different levels of severity. The log levels, ordered from most severe to least severe, are as follows:

Table 1. Log levels
Level	Description
error	Events that indicate a failure.
warn	Events that indicate a problem with operation.
info	Significant events.
debug	Verbose logging. Not usually enabled for production.
trace	High-volume logging of interest only to Push Technology Support. Push Technology Support may occasionally ask you to enable this log level to diagnose issues.

You can use the JavaScript API to enable and configure logging at runtime.

diffusion.log(level)

To disable logging at runtime, set the level to silent.

diffusion.log('silent')

Note: Do not enable logging in your production clients. Use logging only during development of your clients.
