To start using components from this Library

for example in Angular/React:

npm i stenciljs-components

then in main.ts (Angular)/ index.tsx (React):

import { defineCustomElements } from 'stenciljs-components/loader';
// Initialize the custom elements
defineCustomElements(window);

Make sure you have in app.module.ts in Angular (not needed in React)

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
  schemas: [CUSTOM_ELEMENTS_SCHEMA],

then in app.component.html (Angular)/ App.tsx(React) , they can be added as simple tag with any attribute as property in dash-case such as:

<my-card user-name="CodingLocker"></my-card>
<my-pie-chart  data='[{"tag":"height","value":180},{"tag":"weight","value":75},{"tag":"age","value":30},{"tag":"score","value":95},{"tag":"yearsExperience","value":5}]'></my-pie-chart>
<my-rich-text-editor initial-value="this is initial value" placeholder="angular placeholder"></my-rich-text-editor>
<my-progress-bar value="2" max="10"></my-progress-bar>
<my-progress-ring percentage="30"></my-progress-ring>
<test-button button-id="test-button">Click me!</test-button>
 <test-counter>Number: </test-counter>
 <search-world search-text="bmw"> </search-world> 
 <my-payment-gateway></my-payment-gateway>
 <my-component first="Sanjeet" last="Kumar"></my-component>
 <my-button text="Hello"></my-button>
 <parent-component></parent-component>"
 <simple-form first-name="Sanjeet" last-name="Kumar"></simple-form>
 <complex-ionic-form></complex-ionic-form>
 <custom-form></custom-form>
 <combo-box allow-input="true"></combo-box>

This component Library has currently 10 components:

1. my-progress-bar (Props:value,max)
2. my-rich-text-editor (Props:initial-value,placeholder,disabled,disableQuickbars,fontFamily,fontSize) - this is using tinymce under the hood
3. my-progress-ring (Props: percentage, round-linecap, disable-digits,event-id) - this is using easing-animation-frames as dependency
4. my-card (Props:user-name)
5. search-world (Props:search-text)
6. test-button (Props:button-id)
7. test-counter
8. my-pie-chart (Props: data[JSON format where each entry contains only tag and value (in numbers) as keys]) - this is using d3.js under the hood
9. my-payment-gateway - this is using StripeJS payment gateway under the hood
10. my-component (Props:first,middle,last)- default StencilJS Component
11. my-button (Props:text)
12. parent-component (uses embed-component inside it)
13. embed-component
14. simple-form (Props: first-name, last-name; form built using ionic components)
15. complex-ionic-form (form built using ionic components)
16. custom-form (uses combo-box and custom-text-input)
17. combo-box (Props:allow-input, label) -> takes time in React to show arbitrary input in dropdown, foucus out of the field after typing
18. custom-text-input (uses AttachInternals from StencilJS)

Lazy Loading

If you prefer to have your components automatically loaded when used in your application, we recommend enabling the dist output target. The bundle gives you a small entry file that registers all your components and defers loading the full component logic until it is rendered in your application. It doesn't matter if the actual application is written in HTML or created with vanilla JavaScript, jQuery, React, etc.

Stencil Component Starter

This is a starter project for building a standalone Web Component using Stencil.

Stencil is also great for building entire apps. For that, use the stencil-app-starter instead.

Stencil

Stencil is a compiler for building fast web apps using Web Components.

Stencil combines the best concepts of the most popular frontend frameworks into a compile-time rather than runtime tool. Stencil takes TypeScript, JSX, a tiny virtual DOM layer, efficient one-way data binding, an asynchronous rendering pipeline (similar to React Fiber), and lazy-loading out of the box, and generates 100% standards-based Web Components that run in any browser supporting the Custom Elements v1 spec.

Stencil components are just Web Components, so they work in any major framework or with no framework at all.

Getting Started

To start building a new web component using Stencil, clone this repo to a new directory:

git clone https://github.com/ionic-team/stencil-component-starter.git my-component
cd my-component
git remote rm origin

and run:

npm install
npm start

To build the component for production, run:

npm run build

To run the unit tests for the components, run:

npm test

Naming Components

When creating new component tags, we recommend not using stencil in the component name (ex: <stencil-datepicker>). This is because the generated component has little to nothing to do with Stencil; it's just a web component!

Instead, use a prefix that fits your company or any name for a group of related components. For example, all of the Ionic-generated web components use the prefix ion.

Using this component

There are two strategies we recommend for using web components built with Stencil.

The first step for all two of these strategies is to publish to NPM.

You can read more about these different approaches in the Stencil docs.

Lazy Loading

If your Stencil project is built with the dist output target, you can import a small bootstrap script that registers all components and allows you to load individual component scripts lazily.

For example, given your Stencil project namespace is called my-design-system, to use my-component on any website, inject this into your HTML:

<script type="module" src="https://unpkg.com/my-design-system"></script>
<!--
To avoid unpkg.com redirects to the actual file, you can also directly import:
https://unpkg.com/[email protected]/dist/foobar-design-system/foobar-design-system.esm.js
-->
<my-component first="Stencil" middle="'Don't call me a framework'" last="JS"></my-component>

This will only load the necessary scripts needed to render <my-component />. Once more components of this package are used, they will automatically be loaded lazily.

You can also import the script as part of your node_modules in your applications entry file:

import 'foobar-design-system/dist/foobar-design-system/foobar-design-system.esm.js';

Standalone

If you are using a Stencil component library with dist-custom-elements, we recommend importing Stencil components individually in those files where they are needed.

To export Stencil components as standalone components make sure you have the dist-custom-elements output target defined in your stencil.config.ts.

For example, given you'd like to use <my-component /> as part of a React component, you can import the component directly via:

import 'foobar-design-system/my-component';

function App() {
  return (
    <>
      <div>
        <my-component
          first="Stencil"
          middle="'Don't call me a framework'"
          last="JS"
        ></my-component>
      </div>
    </>
  );
}

export default App;
