Plugins

Ajax ships eight plugins. Three run by default on every registration — you do not need to import or configure them. The rest are opt-in: import and pass to ajax.use() for global scope, or include in the plugins array on a specific registration.

Built-in

These are always active:

Plugin	Purpose
headers	Adds X-Ajax-Request: true to every fetch
scripts	Re-executes <script> tags inside swapped elements
events	Dispatches ajax:* CustomEvents on document

Optional

Import from @erikt/ajax and register with ajax.use() or per-registration:

Plugin	Purpose
loading	Sets aria-busy="true" on an element during a request
history	Calls pushState or replaceState after a swap
debug	Logs colored, grouped output for every lifecycle stage
morph	Replaces the default swap with Idiomorph diffing
preload	Preloads links as they scroll into view
