Package description

What is @ardatan/sync-fetch?

@ardatan/sync-fetch is an npm package that provides a synchronous version of the fetch API. This can be particularly useful in environments where asynchronous operations are not feasible or desired, such as in certain testing scenarios or when working with legacy codebases.

What are @ardatan/sync-fetch's main functionalities?

Synchronous HTTP GET Request

This feature allows you to perform a synchronous HTTP GET request. The code sample demonstrates fetching a post from a placeholder API and logging the response data.

const fetch = require('@ardatan/sync-fetch');
const response = fetch('https://jsonplaceholder.typicode.com/posts/1');
const data = response.json();
console.log(data);

Synchronous HTTP POST Request

This feature allows you to perform a synchronous HTTP POST request. The code sample demonstrates sending a POST request to a placeholder API with a JSON payload and logging the response data.

const fetch = require('@ardatan/sync-fetch');
const response = fetch('https://jsonplaceholder.typicode.com/posts', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ title: 'foo', body: 'bar', userId: 1 })
});
const data = response.json();
console.log(data);

Handling HTTP Headers

This feature allows you to include HTTP headers in your synchronous fetch requests. The code sample demonstrates fetching a post with an Authorization header.

const fetch = require('@ardatan/sync-fetch');
const response = fetch('https://jsonplaceholder.typicode.com/posts/1', {
  headers: {
    'Authorization': 'Bearer token'
  }
});
const data = response.json();
console.log(data);

Readme

Source

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)
