# 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,
});
```
