# isSupported

Function @vite-pwa/workbox-swkit/streams

```ts
isSupported(): boolean
```

This is a utility method that determines whether the current browser supports
the features required to create streamed responses. Currently, it checks if
[`ReadableStream`](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream/ReadableStream)
can be created.

**Returns:** `true`, if the current browser meets the requirements for
streaming responses, and `false` otherwise.
