PRESENTA Lib is a config-driven presentation library that creates modern web documents for the automation era.

new Presenta('#wrapper', {
  scenes:[{
    blocks:[{
      type:'text',
      content:`<h1>Hello there</h1>`
    }],
  }]
})

PRESENTA Lib requires a serializable object on purpose, to facilitate interoperability, data transformation as well as fostering novel tools to create presentational documents.

# Installation

PRESENTA Lib is a javascript library without external dependencies. It comes as UMD, thus, you can install it in several ways.

# Unpkg

Include in an existing HTML file quickly:

<script src="https://unpkg.com/@presenta/lib"></script>

<script>
	new Presenta()
</script>

# Skypack

Same as before but in ES6:

<script type="module">

  import Presenta from 'https://cdn.skypack.dev/@presenta/lib'

  new Presenta()

</script>

# Npm+ES6

For Node.js users:

npm install @presenta/lib

then include in the browser with:

<script src="/node_modules/@presenta/lib/dist/presenta.min.js"></script>

<script>
	new Presenta()
</script>

or with an ES6 bundler:

import * as Presenta from '@presenta/lib'

new Presenta()

# Getting started

Each PRESENTA Lib document requires an HTML wrapper:

<div id="app"></div>

Then, bind it (passing both a selector or a DOM node) alongside the config object:

new Presenta('#app', {
    scenes: []
})

Add a scene, an object that contains, at least, the blocks array:

new Presenta('#app', {
    scenes: [{
    	blocks:[]
    }]
})

A block object is the minimal unit of content. The are many block types, text is one of them:

new Presenta('#app', {
    scenes: [{
      blocks:[{
        type: 'text',
        text: '<h1>Welcome PRESENTA</h1>'
      }]
    }]
})

# Architecture

A PRESENTA Lib document contains a list of scenes that can be displayed one at a time. Each scene contains one or more block of content. The scene is responsible to keep blocks together. A block is the minimum unit that renders a specific content from a given config object.

PRESENTA Lib is designed to be extensible by using external plugins. There are three types of plugins, depending of the function you wish to add:

• Blocks (content and media)
• Modules (scene and block extensions)
• Controllers (router controllers or global capabilities)

# Blocks

Each scene can include one or more blocks. A block is responsible to render a specific content or media, such as text, image or video.

You can find additional block types here as external plugins.

# Modules

A module allows to extend a scene or a block both from functional and presentation perspective as well.

Modules config live in their proper field at document level:

{
  scenes:[...],
  modules: {
    steps: true,
    styles: {},
    ...
  },
}

at scene level:

{
  scenes:[{
    blocks:[...],
    modules: {
      steps: true,
      styles: {},
      ...
    },
  }],
  
}

or at block level as well:

{
  scenes:[{
    blocks:[{
        type: 'text',
        content: 'Some Text',
        modules: {
          steps: true,
          styles: {},
          ...
        },
      }
    }]
  }],
  
}

# Controllers

PRESENTA Lib comes with an internal router that can be configured and extended by means of controllers. A controller can provide also global functionality and behaviors that are independent of the routing activity.

Controllers config live in their proper field:

{
  scenes:[...],
  controllers: {
    keyboard: true,
    transitions: {},
    ...
  },
}

Controllers can be set at document level only.
