mergeDefsAndContent()

This function is part of Iconify Utils package.

Function splitSVGDefs() merges definitions and other SVG content in a string.

This function is used by wrapSVGContent() to wrap icon content, which 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:

• defs, string. Definitions.
• content, string. Icon content.

This function returns merged icon as a string.

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>
