  Stencil allows developers to use technologies like TypeScript and JSX to define components, then generate 100% standards-based Web Components that run on both <a href="https://stenciljs.com/docs/browser-support" target="_blank" rel="noopener noref">modern browsers and legacy browsers</a>

### Getting Started

Start a new project by following our quick [Getting Started guide](https://stenciljs.com/docs/getting-started).
We would love to hear from you!
If you have any feedback or run into issues using Stencil, please file an [issue](https://github.com/ionic-team/stencil/issues/new) on this repository.

### Examples
A Stencil component looks a lot like a class-based React component, with the addition of TypeScript decorators:
```tsx
import { Component, Prop, h } from '@stencil/core';

@Component({
  tag: 'my-component',            // the name of the component's custom HTML tag
  styleUrl: 'my-component.css',   // css styles to apply to the component
  shadow: true,                   // this component uses the ShadowDOM
})
export class MyComponent {
  // The component accepts two arguments:
  @Prop() first: string;
  @Prop() last: string;

   //The following HTML is rendered when our component is used
  render() {
    return (
      <div>
        Hello, my name is {this.first} {this.last}
      </div>
    );
  }
}
```

The component above can be used like any other HTML element:

```html
<my-component first="Stencil" last="JS"></my-component>
```

Since Stencil generates web components, they work in any major framework or with no framework at all.
In many cases, Stencil can be used as a drop in replacement for traditional frontend framework, though using it as such is certainly not required.
