What is wire-inspect?

wire-inspect is a small utility library for diagnostics.

How do I use it?

To use wire-inspect, first require the @wirelineio/wire-inspect module in your code:

require('@wirelineio/wire-inspect');

It is activated at runtime via the WIRE_INSPECT environment variable or localStorage.wireInspect setting.
The value should either * to enable everything, or a comma-separated list of specific behaviors to activate.

wire-inspect uses the debug package for logging, so you will usually enable them together, for example:

For example:

WIRE_INSPECT='*' DEBUG='*' node ./src/index.js

or

localStorage.wireInspect = 'event-tracing'
localStorage.debug = 'event-tracing:*'

Behaviors

  • event-tracing Patches EventEmitter, logging when and where events are attached and emitted.
    When emitted, not only the current callstack is shown, but also the callstack from when the event handler was attached.
events:EventEmitter:documents.crdt -> +1s [ 'dWhCnuSlTkKR2qGgVKoIcQ-0', 'jjjj\nk', true ]
