Reusable Components with Stencil

Components are meant to be resuable. However, React components cannot be used in Angular. Angular components cannot be used in Vue. The compiler Stencil.js allows the creation of web components that are framework/library agnostic. Web components are essentially just another HTML element. In this project, we will use Stencil to generate a simple web component that can be published to NPM and consume in any UI framework.

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

Getting Started

git clone https://github.com/etuong/reusable-components.git stencil-demo
cd stencil-demo
git remote rm origin

and run the following to generate a new component:

npm install
npm run generate

To build the component for production, run:

npm run build

Publish to NPM

Create an NPM account and then log in

npm login

and then publish

npm publish

Using this component

Script tag

• Put a script tag similar to this <script type='module' src='https://unpkg.com/my-component@0.0.1/dist/my-component.esm.js'></script> in the head of your index.html
• Then you can use the element anywhere in your template, JSX, html etc
• See MyWebComponent.html for example

Node Modules

• Run npm install my-component --save
• Put a script tag similar to this <script type='module' src='node_modules/my-component/dist/my-component.esm.js'></script> in the head of your index.html

React

• Run npm install my-component --save

• Call defineCustomElements(window) from the index.js file

  import { applyPolyfills, defineCustomElements } from '<your-component-name>/loader';
  
  applyPolyfills().then(() => {
      defineCustomElements(window);
  });

Angular

• Run npm install my-component --save

• Including the CUSTOM_ELEMENTS_SCHEMA in the module

  import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
  
  @NgModule({
      schemas: [CUSTOM_ELEMENTS_SCHEMA],
  })
  export class AppModule {}

• Define the custom elements

  import { defineCustomElements } from '<your-component-name>/loader';
  
  defineCustomElements(window);
