Log all htmx events to console

The htmx.config.logAll option, when set to true, causes htmx to surface event-level output via console.log.

Default: false

Errors and warnings always flow to console.error / console.warn regardless of this flag. logAll controls only the chatty event-by-event output that’s useful when debugging behavior. Most of the time you don’t need it.

Example


htmx.config.logAll = true;


<meta name="htmx-config" content='{"logAll":true}'>

Observability tools (Sentry, DataDog RUM, LogRocket, etc.) capture console.* automatically, so htmx logs flow into your existing pipeline without any extra setup.
