Module fetch 

The WHATWG Fetch globals: fetch, Headers, Request, Response, Blob, FormData, AbortController and AbortSignal.

fetch is not a re-implementation of an HTTP client: it drives the SAME exchange http.request/https.request already perform (http::exchange / https::exchange), on a background thread, and hands the parsed result back over the host’s I/O channel — the pattern every other async native in this frontend uses. That keeps one HTTP/1.1 wire implementation, one chunked decoder and one TLS configuration in the process.

A body is held as raw BYTES (@@body, a JS array of byte numbers) rather than as a string, so arrayBuffer()/bytes() are exact for a binary response and text() decodes UTF-8 once, at the point the caller asks for text. A Response is fully buffered by the time the promise settles, so the body accessors are already-settled promises — the streaming body ReadableStream is the one part of the interface this does not provide.

CLASSES

The classes this module constructs, as bare globals.

Functions

abort_controller_call

abort_signal_call

abort_signal_static

AbortSignal.abort(reason) / AbortSignal.timeout(ms).

body_call

The body accessors shared by Response, Request and Blob. Each answers a settled Promise, because the body is already fully buffered.

construct

construct_abort_controller

construct_blob

construct_file

new File(parts, name[, options]) — a Blob that also carries a name.

construct_form_data

construct_headers

new Headers(init). init is another Headers, an array of [name, value] pairs, or a plain object.

construct_request

new Request(input, init).

construct_response

new Response(body, init).

fetch

fetch(input[, init]) — a Promise for a fully buffered Response.

fire_timeout_abort

Fire an AbortSignal.timeout deadline: abort the signal at heap index idx with a TimeoutError. Reached from the @@aborttimeout:<idx> thunk.

form_data_call

headers_call

instance_call

is_class

methods_for

new_abort_signal

static_call

The static methods of these classes (Response.json, AbortSignal.abort, …).
