Slideshow framework built w/ react-router 4
react-presents
React slideshow framework.
Getting started
Install react-presents
using npm.
npm install react-presents --save
ES6, CommonJS, and UMD builds are available with each distribution. For example:
// Import the components you want like so:
import { Presentation, Slide } from 'react-presents'
Alternately you can load a global-friendly UMD build which exposes a global ReactPresents
object:
<script src="path/to/react-presents/dist/umd/react-presents.js"></script>
Now you're ready to start using the components.
For an example of a the kind of presentations that can be created with react-presents, check out my Connect Tech 2016 presentation on windowing with React: bvaughn.github.io/connect-tech-2016.
Example Usage
Creating a Slide
Presentation slides are simple to create. You can use TitleSlide
and ContentSlide
with some predefined styles, or simply create a slide with custom layout by wrapping its content in div
with 100% height and width. Below is a couple of example slides:
/* SomeSlide.js */
import React from 'react'
import { ContentSlide, Step } from 'react-presents'
export default () => (
<ContentSlide>
<h1>A simple slide</h1>
<p>Slides can contain multiple steps.</p>
<ul>
<Step index={1} exact><li>Sub-text can appear only for a specific step</li></Step>
<Step index={2}><li>Or it can be additive</li></Step>
<Step index={3}><li>(By default it is additive)</li></Step>
<Step index={4} maxIndex={5}><li>They can also be shown for a range</li></Step>
</ul>
</ContentSlide>
)
Automatically Loading Slides
Using a bundler like Webpack, you can auto-load slides using an approach like follows:
Webpack 2
/* Application.js */
const slides = require.context('./path/to/slides/', false, /\.js$/)
.keys()
.map((filename) => filename.replace('./', './path/to/slides/'))
.map((path) => require(path).default)
Webpack 3
/* Application.js */
const slides = []
const context = require.context('./path/to/slides/', false, /\.js$/)
context
.keys()
.forEach(key => slides.push(context(key).default))
Creating a Nav Menu
Once you have an array of loaded slides, you can auto-populate the options for a nav menu using an approach like so:
/* Application.js */
const options = slides
.map((slide, index) => ({
label: slide.title,
value: index
}))
.filter((option) => option.label)
Note that the above approach assumes that slides have a static title
attribute, eg:
/* SomeSlide.js */
import React from 'react'
import { ContentSlide } from 'react-presents'
const slide = () => (
<ContentSlide>
<h1>{slide.title}</h1>
{/* Your content goes here */}
</ContentSlide>
)
slide.title = 'The first slide'
export default slide
Also note that react-select is used beneath the hood so the options
array you construct must be compatible with it.
Creating a presentation
Assuming you have an array of slides and options for the drop-down nav, you can create a presentation like follows:
import React from 'react'
import { Presentation, Slide, DropDownNav } from 'react-presents'
export default () => (
<Presentation>
{slides.map((Component, index) => (
<Slide
component={Component}
key={index}
/>
)).concat(
<DropDownNav
key='DropDownNav'
options={options}
/>
)}
</Presentation>
)
A default theme is provided with react-presents. You can disable this theme by specifying the disableTheme
property:
<Presentation disableTheme>
{slides}
</Presentation>
