Exporting icon set as JSON package

This tutorial is part of export functions documentation in Iconify Tools.

Function exportJSONPackage() creates an icon package in specified directory.

These packages are used to load an entire icon sets, like this:

jsimport { addCollection, Icon } from '@iconify/react';
import { icons as mdiLightIcons } from '@iconify-json/mdi-light';
import { icons as tablerIcons } from '@iconify-json/tabler';


// Demo using some of imported icons
export function renderHomeIcon() {
   return <Icon icon="mdi-light:home" />;

export function renderAlertIcon() {
   return <Icon icon="tabler:alert-octagon" />;

@iconify-json/mdi-light and @iconify-json/tabler are packages generated by this function, used in example above.

See individual icon set packages documentation for details.


Function has the following parameters:

  • iconSet, IconSet. Icon set to export.
  • options, object. Options. See below.

Function returns array of generated files.

Function is asynchronous. That means you need to handle it as Promise instance, usually by adding await before function call.


Options object has the following mandatory property:

  • target, string. Target directory. If directory is missing, it will be created.

and the following optional properties:

  • cleanup, boolean. If true, target directory will be emptied before exporting icons. Default is false.
  • package, object. Properties for package.json. Use this to set at least package name and version.
  • customFiles, Record<string,unknown>. Custom files to export. Key is filename, value is content. See below.


customFiles option contains additional files you want to add to package. Key is filename, value can be one of these types:

  • string. Content of file.
  • object. JSON content that will be serialized before writing file.
  • null. If value is null, file is deleted.
