Synchronous version of the Fetch API

Package Exports

  • @ardatan/sync-fetch
  • @ardatan/sync-fetch/browser.js
  • @ardatan/sync-fetch/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ardatan/sync-fetch) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

sync-fetch

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

npm

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)
