Iconify parts


There are several parts of project, some are in this repository, some are in other repositories.

What is included in this repository?

-   Directory packages contains main reusable packages: types, utilities, reusable functions used by various components.
-   Directory iconify-icon contains iconify-icon web component that renders icons. It also contains wrappers for various frameworks that cannot handle web components.
-   Directory components contains older version of icon components that are native to various frameworks, which do not use web component.

Other repositories you might want to look at:

-   Data for all icons is available in [iconify/icon-sets](https://github.com/iconify/icon-sets) repository.
-   Tools for parsing icons and generating icon sets are available in [iconify/tools](https://github.com/iconify/tools) repository.

Iconify icon components


Main packages in this repository are various icon components.

Why are those icon components needed? Iconify icon components are not just yet another set of icon components. Unlike other icon components, Iconify icon components do not include icon data. Instead, icon data is loaded on demand from Iconify API.

Iconify API provides data for over 100,000 open source icons! API is hosted on publicly available servers, spread out geographically to make sure visitors from all over the world have the fastest possible connection with redundancies in place to make sure it is always online.

Why is API needed?


When you use an icon font, each visitor loads an entire font, even if your page only uses a few icons. This is a major downside of using icon fonts. That limits developers to one or two fonts or icon sets.

If you are using typical icon set that is not a font, you still need to bundle all icons used in your application, even ones that visitor does not need.

Unlike icon fonts and components for various icon sets, Iconify icon components dynamically load icon data from Iconify API whenever it is needed.

This makes it possible to have an unlimited choice of icons!

Packages in this repository


There are several types of packages, split in their own directories.

Main packages


Directory packages contains main packages that are reusable by all other packages in this repository as well as third party components.

Main packages:

-   Iconify types - TypeScript types.
-   Iconify utils - common files used by various Iconify projects (including tools, API, etc...).
-   Iconify core - common files used by various icon components.
-   API redundancy - library for managing redundancies for loading data from API: handling timeouts, rotating hosts.

Web component


Directory iconify-icon contains iconify-icon web component and wrappers for various frameworks.

PackageUsage
--------------------------------------------------
[WebEverywhere
[ReactReact
[SolidJSSolidJS

Frameworks that are confirmed to work with web components without custom wrappers:

-   Svelte.
-   Lit.
-   Ember.
-   Vue 2 and Vue 3, but requires custom config when used in Nuxt (see below).
-   React, but with small differences, such as using class instead of className. Wrapper fixes it and provides types.

Demo


Directory iconify-icon-demo contains demo packages that show usage of iconify-icon web component.

-   Ember demo - demo using web component with Ember. Runnpm run build to build demo and npm run start to start it.
-   React demo - demo using web component with React. Runnpm run dev to start demo.
-   Next.js demo - demo for web component with Next.js. Runnpm run dev to start demo.
-   Svelte demo with Vite - demo for web component with Svelte using Vite. Runnpm run dev to start demo.
-   SvelteKit demo - demo for web component with SvelteKit. Runnpm run dev to start the demo.
-   Vue 3 demo - demo for web component with Vue 3. Runnpm run dev to start demo.
-   Nuxt 3 demo - demo for web component with Nuxt 3. Runnpm run dev to start demo. Requires custom config, see below.
-   Vue 2 demo - demo for web component with Vue 2. Runnpm run build to build demo and npm run serve to start it.
-   SolidJS demo - demo using web component with SolidJS. Runnpm run dev to start demo.
-   Lit demo - demo for web component with Lit. Runnpm run start to start demo.

Nuxt 3 usage


When using web component with Nuxt 3, you need to tell Nuxt that iconify-icon is a custom element. Otherwise it will show few errors.

Example nuxt.config.ts:

  1. ```ts
  2. import { defineNuxtConfig } from 'nuxt3';

  3. export default defineNuxtConfig({
  4. vue: {
  5.   compilerOptions: {
  6.    isCustomElement: (tag) => tag === 'iconify-icon',
  7.   },
  8. },
  9. });
  10. ```

This configuration change is not needed when using Vue with @vitejs/plugin-vue.

Deprecation notice


Components in directory components are slowly phased out in favor of iconify-icon web component. Components are still maintained and supported, but it is better to switch to web component.

Functionality is identical, but web component has some advantages:

-   No framework specific shenanigans. Events and attributes are supported for all frameworks.
-   Works better with SSR (icon is rendered only in browser, but because icon is contained in shadow DOM, it does not cause hydration problems).
-   Better interoperability. All parts of applicaiton reuse same web component, even if those parts are written in different frameworks.

Deprecation status:

-   SVG Framework: can be replaced with iconify-icon.
-   React component: can be replaced with iconify-icon using @iconify-icon/react wrapper.
-   Svelte component: can be replaced with iconify-icon, does not require Svelte specific wrapper.
-   Vue 3 component: can be replaced with iconify-icon, does not require Vue specific wrapper.
-   Vue 3 component: can be replaced with iconify-icon, does not require Vue specific wrapper. Make sure you are not using Webpack older than version 5.
-   Ember component: can be replaced with iconify-icon, does not require Ember specific wrapper.

To import web component, just import it once in your script, as per [iconify-icon README file](./iconify-icon/icon/README.md).
