Advanced-fetch NPM

advanced-fetch

A version of node-fetch with more convenient functionality.

Installation

npm install advanced-fetch

Usage

const { Fetch } = require("advanced-fetch");

(async () => {
  const fetch = new Fetch();
  await fetch.get("http://example.com");
  // subsequent requests to example.com now send the received
  // cookies again, and the cookies are updated automatically
})();

Constructor

The Fetch constructor expects an optional object, with the following possible attributes:

cookiesFilename: If given, the tough-cookie cookie jar is serialized into JSON after each request and that JSON is written into the specified file.
encoding: If given, the received responses are assumed to be in that text encoding and converted automatically to UTF-8 via iconv-lite before they are returned to you.

Request parameters

Supports .get, .post, .put and .delete. After the URL, all of these functions also expect an optional object with node-fetch request parameters.

Additionally, you can specify the following parameters as normal JavaScript objects, which are serialized respectively automatically:

query for GET query parameters, internally serialized using querystring
form for the body of a Content-Type: application/x-www-form-urlencoded request, internally serialized using URLSearchParams
formData for the body of a Content-Type: multipart/form-data request, internally serialized using form-data
json for the body of a Content-Type: application/json request, internally serialized using JSON.stringify

Finally, you can specify returnBuffer: true in the parameters object in order to get a Node.js Buffer as the result of a request instead of a string.
