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.
<script src="https://unpkg.com/sync-fetch"></script>
<script src="https://unpkg.com/sync-fetch@VERSION"></script>
Use
const fetch = require('sync-fetch')
const metadata = fetch('https://doi.org/10.7717/peerj-cs.214', {
headers: {
Accept: 'application/vnd.citationstyles.csl+json'
}
}).json()
Limitations
Node.js
- 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
Browser
- 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)
