Bundle size
Because of the way Stencil relies on its CLI to abstract away the rollup build, I haven't figured out the right way to get the rollup-plugin-filesize plugin to work. I tried adding it to the build, but it was telling me the whole thing was a couple hundred bytes, so that's wrong. However, when running a dev server not in dev mode, mycomponent.core.js
comes in at 6.8KB gzipped and 14.3KB unzipped and my-component.entry.js
adds another 578B gzipped/381B unzipped (those numbers are confusing...). Those are the only two scripts being loaded on the page.
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 run-time 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
Script tag
- Publish to NPM
- Put a script tag similar to this
<script src='https://unpkg.com/my-component@0.0.1/dist/mycomponent.js'></script>
in the head of your index.html - Then you can use the element anywhere in your template, JSX, html etc
Node Modules
- Run
npm install my-component --save
- Put a script tag similar to this
<script src='node_modules/my-component/dist/mycomponent.js'></script>
in the head of your index.html - Then you can use the element anywhere in your template, JSX, html etc
In a stencil-starter app
- Run
npm install my-component --save
- Add an import to the npm packages
import my-component;
- Then you can use the element anywhere in your template, JSX, html etc
