The industry standard for API mocking in JavaScript.

//#region src/utils/is-common-asset-request.ts
/**
* Determines if the given request is a static asset request.
* Useful when deciding which unhandled requests to ignore.
* @note Despite being ignored, you can still intercept and mock
* static assets by creating request handlers for them.
*
* @example
* import { isCommonAssetRequest } from 'msw'
* import { HttpNetworkFrame } from 'msw/experimental'
*
* await worker.start({
*   onUnhandledFrame({ frame, defaults }) {
*     if (frame instanceof HttpNetworkFrame && !isCommonAssetRequest(frame.data.request)) {
*       defaults.warn()
*     }
*   }
* })
