x-interact:stream

x-interact:stream declares a named, display-only target inside an island. Streaming actions append or replace its content before the final action result arrives.

<pre x-interact:stream="answer"></pre>

Call $this->stream('answer', $text) from a #[Action(stream: true)] method. Content is appended as literal text. Use replace: true in PHP to replace it. Multiple matching targets in the owning island receive the same update; child islands retain their own scope. Missing targets are ignored.

HTML elements

<ul x-interact:stream.html="rows"></ul>

Use streamElement('rows', 'row', ['item' => $item]) to render native HTML with explicit variables. Escape application values inside the element. HTML and text modes must match; Alpine initializes appended HTML and cleans up replaced content.

Options and ownership

Syntax	Content
x-interact:stream="name"	Literal text from stream()
x-interact:stream.html="name"	Native element HTML from streamElement()

The value is a literal lowercase identifier matching [a-z][a-z0-9:-]*, rather than an Alpine expression. .html is the only modifier. The island root cannot be a target.

Keep controls, child islands, ignored widget regions, executable scripts, runtime metadata, and nested stream targets outside streamed content. Changes are provisional: the final normal render is authoritative. See completion and failures and the complete report example.
