# FicusJS core

FicusJS core provides functions for creating fast, lightweight web components
and modules for packaging sets of components.

Components created with FicusJS are native custom elements
created in a functional and declarative way.

A set of components can be shared as a module using a package manager or publishing it to a URL.
By packaging your components into a module, it can be imported into other applications and re-used multiple times.

For documentation visit [https://docs.ficusjs.org/](https://docs.ficusjs.org/)

## Getting started

The `createCustomElement` function defines a new component with the provided tag plus declarative object and registers it in the browser as a [custom element](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_custom_elements).

```js
// import the createCustomElement function
import { createCustomElement } from 'https://cdn.skypack.dev/@ficusjs/core'

// import the renderer and html tagged template literal from the htm renderer
import { html, renderer } from 'https://cdn.skypack.dev/@ficusjs/renderers@5/htm'

createCustomElement('my-component', {
  renderer,
  props: {
    personName: {
      type: String,
      required: true
    }
  },
  render () {
    return html`
      <p>
        Hi, there! My name is ${this.props.personName}
      </p>
    `
  }
})
```

The `use` function will import a module of components into your application ready to use.

```js
// import the use function
import { use } from 'https://cdn.skypack.dev/@ficusjs/core'

// import the renderer and html tagged template literal from the uhtml renderer
import { html, renderer } from 'https://cdn.skypack.dev/@ficusjs/renderers@5/uhtml'

// import component module from a local path
import { module } from './path/to/component-module.esm.js'

// import the components into your application, passing the renderer and html tagged template literal to the module
use(module, { renderer, html })
```

See the [documentation](https://docs.ficusjs.org/modules/) for more information on creating and consuming modules.

## Installation

FicusJS core is part of [FicusJS](https://docs.ficusjs.org) but can also be installed independently in a number of ways.

### CDN

We recommend using native ES modules in the browser.

```html
<script type="module">
  import { createCustomElement, use } from 'https://cdn.skypack.dev/@ficusjs/core'
</script>
```

FicusJS core is available on [Skypack](https://www.skypack.dev/view/@ficusjs/core).

### NPM

FicusJS core work nicely with build tools such as Snowpack, Webpack or Rollup. If you are using a NodeJS tool, you can install the NPM package.

```bash
npm install @ficusjs/core
```

### Available builds

FicusJS core only provides ES module builds. For legacy browsers or alternative modules such as CommonJS, it is recommended to use a build tool to transpile the code.
