SVG framework internal function: setFetch
This tutorial is part of Iconify SVG Framework functions tutorial.
The function setFetch() can be used to load Fetch API implementation.
Why is it needed?
When using the SVG framework in a browser, it relies on fetch() to retrieve data from Iconify API.
All modern browsers support it.
Older versions of Node.js do not support Fetch API. It is available in Node.js version 17 using flag "--experimental-fetch", but without it, Fetch API is not available. That means the icon component cannot retrieve icon data from Iconify API when used on a server side in Node.js environment.
The function has the following parameter:
- fetch. Function fetch().
- Install (if you are using CommonJS) or (if you are using modules) as dependency.
- Use internal setFetch() function to set third party Fetch API before using any SVG framework functions.
import Iconify from '@iconify/iconify';
import fetch from 'cross-fetch';
// import fetch from 'node-fetch';
// Set Fetch API before doing anything
