# WebAPI
**WebAPI** lets you use Web APIs in Node v12, v14, and v16.
```sh
npm install @astrojs/webapi
```
```js
import { polyfill } from '@astrojs/webapi'
polyfill(globalThis)
const t = new EventTarget()
const e = new CustomEvent('hello')
t.addEventListener('hello', console.log)
t.dispatchEvent(e) // logs `e` event from `t`
```
These APIs are combined from popular open source projects and configured to share implementation details. This allows their behavior to match browser expectations as well as reduce their combined memory footprint.

## Usage
You can use WebAPIs as individual exports.
```js
import { AbortController, Blob, Event, EventTarget, File, fetch, Response } from '@astrojs/webapi'
```
You can apply WebAPIs to an object, like `globalThis`.
```js
import { polyfill } from '@astrojs/webapi'
polyfill(globalThis)
```
## Polyfill Options
The `exclude` option receives a list of WebAPIs to exclude from polyfilling.
```js
polyfill(globalThis, {
// disables polyfills for setTimeout clearTimeout
exclude: 'setTimeout clearTimeout',
})
```
The `exclude` option accepts shorthands to exclude multiple polyfills. These shorthands end with the plus sign (`+`).
```js
polyfill(globalThis, {
// disables polyfills for setTimeout clearTimeout
exclude: 'Timeout+',
})
```
```js
polyfill(globalThis, {
// disables polyfills for Node, Window, Document, HTMLElement, etc.
exclude: 'Node+',
})
```
```js
polyfill(globalThis, {
// disables polyfills for Event, EventTarget, Node, Window, Document, HTMLElement, etc.
exclude: 'Event+',
})
```
