sync-fetch

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

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()
// json(), arrayBuffer(), text() and buffer() supported

Limitations

Node.js

• Does not support Streams (or FormData) as input bodies since they cannot be read or serialized synchronously
• Does not support Blobs as input bodies since they're too complex
• Does not support the non-spec agent option as its value cannot be serialized

Browser

• Does not support most options, since XMLHttpRequest is pretty limited. Supported are:
  • method
  • body
  • headers
  • credentials (but not omit)
  • (Non-spec) timeout
• Does not support binary responses in the main thread
• CORS limitations apply, of course (note they may be stricter for synchronous requests)
