PRESENTA Lib

# Guide

In this section you'll learn the basics of PRESENTA Lib.

# Installation

You can start with the library in several ways depending of your favorite setup.

# Local starterkit

You can download this zip(opens new window) that contains a starter example you can edit locally. Just double-click the index.html file to run your presentation even if offline.

# Remote starterkit

You can start with the same example by forking this Codepen(opens new window) , Glitch(opens new window) or Repl(opens new window) project. Your call.

# Unpkg

If you want to include it in an existing HTML file quickly:

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

# Npm+ES6

If you have a local development toolchain up and running:

npm install @presenta/lib

then include in the browser with:

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

or using with a ES6 bundler:

import * as Presenta from '@presenta/lib'

# Getting started with the library

First thing first: each PRESENTA Lib document requires an HTML wrapper:

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

Then, bind it (passing both a selector or a DOM node) with 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>'
      }]
    }]
})

TEXT Block and HTML

The built-in text block renders a subset of HTML tags properly. However, there is a markdown-to-HTML plugin to avoid writing raw tags.

# Blocks and content types

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.

PRESENTA Lib includes the following built-in blocks you can explore briefly here:






You can find additional block types here as external plugins.

To learn more about each block specific settings, jump to this section of the Reference.

# Controls and behaviors

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,
    arrows: true,
    ...
  },
}

To learn more about the available controllers and their specific settings, jump to this section of the Reference.

# Styles and Transitions

A PRESENTA Lib document can be styled by leveraging the combination of some properties:

new Presenta('#app', {
  	colors: 'adele',
  	fonts: 'duck',
  	colorVar: 'alt',
  	transition: 'hSlide',
    scenes:[...]
})

Refer to this section of the Reference to learn about the available values.

# Property inheritance

An important concept to remember is the properties inheritance depending where they are set. Any property (be aware, not option) can be set at presentation level, scene level and block level as well. The more specific place, the higher priority, just like CSS.

On the other hand, options are context specific, therefore, they don't inherit from higher levels.
