Node Logging

Logging example with plain-text and JSON logs.

Deploy

$ up

Usage

Tail the logs in one tab:

$ up logs -f

Hit the plain-text route a few times and you should see the logs.

$ curl `up url`/text

Hit the json route to see how the JSON logs are translated to the internal format, allowing you to specify fields etc.

$ curl `up url`/json

The following end-point outputs a stack trace:

$ curl `up url`/stack

Or alternatively crash and output an error in the uncaughtException handler.

$ curl `up url`/crash

Notes

JSON logs need at least these fields:

• level (string) – severity level
• message (string) – log message

Optionally:

• fields (object) – key/value pairs for contextual information
