fetch()

Using the `fetch()` global function

nx.js implements the fetch() global function for fetching data from the network. If you are familiar with the Fetch API, then you will find the nx.js fetch() function very similar.

The following URL protocols are supported:

• http: - Fetch data from the network using the HTTP protocol
• https: - Fetch data from the network using the HTTPS protocol
• blob: - Fetch data from a URL constructed by URL.createObjectURL()
• data: - Fetch data from a Data URI (possibly base64-encoded)
• sdmc: - Fetch data from a local file on the SD card
• romfs: - Fetch data from the RomFS partition of the nx.js application
• file: - Same as sdmc:

Usage

The fetch() function takes a URL as its first argument, and returns a Promise that resolves to a Response object. The Response object contains information about the fetched data, such as the status code, headers, and body.

const response = await fetch('https://example.com/data.json');
console.log(response.status); // 200
console.log(response.headers.get('Content-Type')); // 'application/json'
console.log(await response.json()); // { name: 'John Doe' }

You can also pass additional options to the fetch() function to customize its behavior. For example, you can specify a method to use for the request, or a body to send along with the request.

const response = await fetch('https://example.com/data.json', {
  method: 'POST',
  body: JSON.stringify({ name: 'John Doe' }),
});
