wrapSVGContent()

This function is part of Iconify Utils package.

Function wrapSVGContent() wraps icon body in custom code.

It is used by iconToSVG() to apply flip and rotation to icon, by buildParsedSVG() and convertParsedSVG() to move presentational attributes from <svg> element to a group element.

Usage

This function has the following parameters:

• body, string. Icon content.
• start, string. Start of wrapper, such as <g>.
• end, string. End of wrapper, such as </g>.

This function extracts definitions from icon content, merges the rest of icon as "start + content + end", merges it with previously extracted definitions.

Example

example.ts

tsimport type { IconifyIcon } from '@iconify/types';
import { splitSVGDefs, mergeDefsAndContent, wrapSVGContent } from '@iconify/utils';

// Source icon, which contains definitions block
// This code works for icons without definitions block too, so no need to check if an icon actually has <defs>
const icon: IconifyIcon = {
