The fetch API

The Fetch API provides us with an interface for fetching resources (including external data through the network). The main fetch method returns a Promise that resolves to a Response regardless of the status code the server returned in the response.

The fetch method takes one mandatory parameter: the path of the resource we want to fetch. We can optionally specify a second parameter that customizes the behavior of the Request.

Fetch API

Code example

Here we are using the official Wikipedia API to search for Norway.

const path = "https://en.wikipedia.org/w/api.php?origin=*&action=opensearch&search=Norway"
fetch(path)
  .then(response => response.json())
  .then(console.log)
