deno web

Implements timers, as well as the following APIs:

Note: Testing for text encoding is done via WPT in cli/.

Usage Example

From javascript, include the extension's source:

import * as infra from "ext:deno_web/00_infra.js";
import * as DOMException from "ext:deno_web/01_dom_exception.js";
import * as mimesniff from "ext:deno_web/01_mimesniff.js";
import * as event from "ext:deno_web/02_event.js";
import * as structuredClone from "ext:deno_web/02_structured_clone.js";
import * as timers from "ext:deno_web/02_timers.js";
import * as abortSignal from "ext:deno_web/03_abort_signal.js";
import * as globalInterfaces from "ext:deno_web/04_global_interfaces.js";
import * as base64 from "ext:deno_web/05_base64.js";
import * as streams from "ext:deno_web/06_streams.js";
import * as encoding from "ext:deno_web/08_text_encoding.js";
import * as file from "ext:deno_web/09_file.js";
import * as fileReader from "ext:deno_web/10_filereader.js";
import * as location from "ext:deno_web/12_location.js";
import * as messagePort from "ext:deno_web/13_message_port.js";
import * as compression from "ext:deno_web/14_compression.js";
import * as performance from "ext:deno_web/15_performance.js";
import * as imageData from "ext:deno_web/16_image_data.js";

Then assign the properties below to the global scope like this example:

Object.defineProperty(globalThis, "AbortController", {
  value: abortSignal.AbortController,
  enumerable: false,
  configurable: true,
  writable: true,
});

structuredClone messagePort.structuredClone true true true

Then from rust, provide: deno_web::deno_web::init_ops_and_esm::<Permissions>(Arc<BlobStore>, Option<Url>) in the extensions field of your RuntimeOptions

Where:

  • Permissions is a struct implementing deno_web::TimersPermission
  • Arc<BlobStore> can be provided by Default::default()
  • Option<Url> provides an optional base URL for certain ops

Dependencies

  • deno_webidl: Provided by the deno_webidl crate
  • deno_console: Provided by the deno_console crate
  • deno_url: Provided by the deno_url crate

Provided ops

Following ops are provided, which can be accessed through Deno.ops:

  • op_base64_decode
  • op_base64_encode
  • op_base64_atob
  • op_base64_btoa
  • op_encoding_normalize_label
