@poppy-ui/core

Poppy-ui is an open source App Development UI that makes it easy to build top quality Progressive Web Apps with web technologies.

The Poppy-ui Core package contains the Web Components that make up the reusable UI building blocks of Poppy-ui. These components are designed to be used in traditional frontend view libraries/frameworks (such as Stencil, React, Angular, or Vue), or on their own through traditional JavaScript in the browser.

Features

• Tiny, highly optimized components built with Stencil
• No build or compiling required
• Simply add the static files to any project
• Lazy-loaded components without configuration
• Asynchronous rendering
• Theming through CSS Variables

How to use

Vanilla HTML

Easiest way to start using Poppy-ui Core is by adding a script tag to the CDN:

<script type="module" src="https://cdn.jsdelivr.net/npm/@poppy-ui/core/dist/poppy/poppy.esm.js"></script>
<script nomodule src="https://cdn.jsdelivr.net/npm/@poppy-ui/core/dist/poppy/poppy.js"></script>
<link href="https://cdn.jsdelivr.net/npm/@poppy-ui/core/css/poppy.bundle.css" rel="stylesheet">

Any Poppy component added to the webpage will automatically load. This includes writing the component tag directly in HTML, or using JavaScript such as document.createElement('pop-button').

Additionally, within this package is a dist/poppy.js file and accompanying dist/poppy/ directory. These are the same files which are used by the CDN, and they're available in this package so they can be apart of an app's local development.

Framework Bindings

The @poppy-ui/core package can be used in simple HTML, or by vanilla JavaScript without any framework at all. Poppy also has packages that make it easier to integrate Poppy into a framework's traditional ecosystem and patterns. (However, at the lowest-level framework bindings are still just using Poppy Core and Web Components).

Custom Elements Build

In addition to the default, self lazy-loading components built by Stencil, this package also comes with each component exported as a stand-alone custom element within @poppy-ui/core/components. Each component extends HTMLElement, and does not lazy-load itself. Instead, this package is useful for projects already using a bundler such as Webpack or Rollup. While all components are available to be imported, the custom elements build also ensures bundlers only import what's used, and tree-shakes any unused components.

Below is an example of importing pop-badge. Additionally, the initialize({...}) function can receive the Poppy config.

import { defineCustomElement } from "@poppy-ui/core/components/pop-badge.js";
import { initialize } from "@poppy-ui/core/components";

// Initializes the Poppy config
initialize();

// Defines the `pop-badge` web component
defineCustomElement();

Notice how we import from @poppy-ui/core/components as opposed to @poppy-ui/core. This helps bundlers pull in only the code that is needed.

The defineCustomElement function will automatically define the component as well as any child components that may be required.

For example, if you wanted to use pop-modal, you would do the following:

import { defineCustomElement } from "@poppy-ui/core/components/pop-modal.js";
import { initialize } from "@poppy-ui/core/components";

// Initializes the Poppy config
initialize();

// Defines the `pop-modal` and child `pop-backdrop` web components.
defineCustomElement();

The defineCustomElement function will define pop-modal, but it will also define pop-backdrop, which is a component that pop-modal uses internally.

Using Overlay Controllers

When using an overlay controller, developers will need to define the overlay component before it can be used. Below is an example of using modalController:

import { defineCustomElement } from '@poppy-ui/core/components/pop-modal.js';
import { initialize, modalController } from '@poppy-ui/core/components';

initialize();
defineCustomElement();

const showModal = async () => {
  const modal = await modalController.create({ ... });
  
  ...
}
