deno web

实现了定时器以及以下API

注意:文本编码测试是通过 cli/ 中的 WPT 进行的。

使用示例

从 JavaScript 中,包含扩展的源代码

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";

然后将以下属性赋值给全局作用域,例如以下示例

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

然后从Rust提供:deno_web::deno_web::init_ops_and_esm::<Permissions>(Arc<BlobStore>, Option<Url>) 在你的 RuntimeOptionsextensions 字段中

其中

  • Permissions 是一个实现了 deno_web::TimersPermission 的结构体
  • Arc<BlobStore> 可以通过 Default::default() 提供
  • Option<Url> 为某些操作提供一个可选的基本URL

依赖项

  • deno_webidl:由 deno_webidl 包提供
  • deno_console:由 deno_console 包提供
  • deno_url:由 deno_url 包提供

提供的操作

以下操作已提供,可以通过 Deno.ops 访问

  • op_base64_decode
  • op_base64_encode
  • op_base64_atob
  • op_base64_btoa
