sync-fetch

Synchronous wrapper around the Fetch API. Uses node-fetch under the hood, and for some input-parsing code and test cases too.


Install

npm install sync-fetch

In the browser, a browserify bundle can be loaded from CDNs like unpkg.com.

``html


`

Use

`js
const fetch = require('sync-fetch')

const metadata = fetch('https://doi.org/10.7717/peerj-cs.214', {
headers: {
Accept: 'application/vnd.citationstyles.csl+json'
}
}).json()
// arrayBuffer(), blob(), buffer(), json(), and text() supported
`

Limitations

$3

- Does not support Stream or Blob as input body since they cannot be read or serialized synchronously
- Does not support FormData as input body yet as it has no built-in method to be serialized
- Does not support the non-spec agent option as its value cannot be serialized
- Does not support non-standard textConverted() method on SyncResponse and SyncRequest

$3

- Does not support most options, since XMLHttpRequest is pretty limited. Supported are:
- method
- body
- headers
- credentials (but not omit)
- (Non-spec) timeout
- The non-standard buffer() and textConverted()` methods are not supported
- CORS limitations apply, of course (note they may be stricter for synchronous requests)
