# deno web **Implements timers, as well as the following APIs:** - Event - TextEncoder - TextDecoder - File (Spec: https://w3c.github.io/FileAPI) _Note: Testing for text encoding is done via WPT in cli/._ ## Usage Example From javascript, include the extension's source: ```javascript 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: ```javascript Object.defineProperty(globalThis, "AbortController", { value: abortSignal.AbortController, enumerable: false, configurable: true, writable: true, }); ``` | Name | Value | enumerable | configurable | writeable | | -------------------------------- | ---------------------------------------- | ---------- | ------------ | --------- | | AbortController | abortSignal.AbortController | false | true | true | | AbortSignal | abortSignal.AbortSignal | false | true | true | | Blob | file.Blob | false | true | true | | ByteLengthQueuingStrategy | streams.ByteLengthQueuingStrategy | | | | | CloseEvent | event.CloseEvent | false | true | true | | CompressionStream | compression.CompressionStream | false | true | true | | CountQueuingStrategy | streams.CountQueuingStrategy | | | | | CustomEvent | event.CustomEvent | false | true | true | | DecompressionStream | compression.DecompressionStream | false | true | true | | DOMException | DOMException | false | true | true | | ErrorEvent | event.ErrorEvent | false | true | true | | Event | event.Event | false | true | true | | EventTarget | event.EventTarget | false | true | true | | File | file.File | false | true | true | | FileReader | fileReader.FileReader | false | true | true | | MessageEvent | event.MessageEvent | false | true | true | | Performance | performance.Performance | false | true | true | | PerformanceEntry | performance.PerformanceEntry | false | true | true | | PerformanceMark | performance.PerformanceMark | false | true | true | | PerformanceMeasure | performance.PerformanceMeasure | false | true | true | | PromiseRejectionEvent | event.PromiseRejectionEvent | false | true | true | | ProgressEvent | event.ProgressEvent | false | true | true | | ReadableStream | streams.ReadableStream | false | true | true | | ReadableStreamDefaultReader | streams.ReadableStreamDefaultReader | | | | | TextDecoder | encoding.TextDecoder | false | true | true | | TextEncoder | encoding.TextEncoder | false | true | true | | TextDecoderStream | encoding.TextDecoderStream | false | true | true | | TextEncoderStream | encoding.TextEncoderStream | false | true | true | | TransformStream | streams.TransformStream | false | true | true | | MessageChannel | messagePort.MessageChannel | false | true | true | | MessagePort | messagePort.MessagePort | false | true | true | | WritableStream | streams.WritableStream | false | true | true | | WritableStreamDefaultWriter | streams.WritableStreamDefaultWriter | | | | | WritableStreamDefaultController | streams.WritableStreamDefaultController | | | | | ReadableByteStreamController | streams.ReadableByteStreamController | | | | | ReadableStreamBYOBReader | streams.ReadableStreamBYOBReader | | | | | ReadableStreamBYOBRequest | streams.ReadableStreamBYOBRequest | | | | | ReadableStreamDefaultController | streams.ReadableStreamDefaultController | | | | | TransformStreamDefaultController | streams.TransformStreamDefaultController | | | | | ImageData | imageData.ImageData | false | true | true | | atob | base64.atob | true | true | true | | btoa | base64.btoa | true | true | true | | clearInterval | timers.clearInterval | true | true | true | | clearTimeout | timers.clearTimeout | true | true | true | | performance | performance.performance | true | true | true | | reportError | event.reportError | true | true | true | | setInterval | timers.setInterval | true | true | true | | setTimeout | timers.setTimeout | true | true | 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 - op_encoding_decode_single - op_encoding_decode_utf8 - op_encoding_new_decoder - op_encoding_decode - op_encoding_encode_into - op_blob_create_part - op_blob_slice_part - op_blob_read_part - op_blob_remove_part - op_blob_create_object_url - op_blob_revoke_object_url - op_blob_from_object_url - op_message_port_create_entangled - op_message_port_post_message - op_message_port_recv_message - op_message_port_recv_message_sync - op_compression_new - op_compression_write - op_compression_finish - op_now - op_defer - op_readable_stream_resource_allocate - op_readable_stream_resource_allocate_sized - op_readable_stream_resource_get_sink - op_readable_stream_resource_write_error - op_readable_stream_resource_write_buf - op_readable_stream_resource_write_sync - op_readable_stream_resource_close - op_readable_stream_resource_await_close
