THIS FORK IS CLOSED
I'm glad to announce that all the work in this fork was eventually merged back upstream. It's now available at https://github.com/impress/impress.js as of release 1.0.0-beta1. There will be no more commits to this fork.
It's a presentation framework based on the power of CSS3 transforms and transitions in modern browsers and inspired by the idea behind prezi.com.
impress.js may not help you if you have nothing interesting to say ;)
HOW TO USE IT
Checking out and initializing the git repository
git clone --recursive https://github.com/henrikingo/impress.js.git cd impress.js
Note: For a minimal checkout, omit the
--recursive option. This will leave out extra plugins.
Reference documentation of all impress.js features and API you can find it in DOCUMENTATION.md.
Examples and demos
The Classic Slides demo is targeted towards beginners, or can be used as a template for presentations that look like the traditional PowerPoint slide deck. Over time, it also grew into the example presentation that uses most of the features and addons available.
More examples and demos can be found on Examples and demos wiki page.
Feel free to add your own example presentations (or websites) there.
Other tutorials and learning resources
If you want to learn even more there is a list of tutorials and other learning resources on the wiki, too.
There is also a book available about Building impressive presentations with impress.js by Rakhitha Nimesh Ratnayake.
You may want to check out the sibling project [Impressionist|https://github.com/henrikingo/impressionist]: a 3D GUI editor that can help you in creating impress.js presentations.
You're welcome to ask impress.js related questions on the impressionist-presentations mailing list.
- index.html: This is the official impress.js demo, showcasing all of the features
of the original impress.js, as well as some new plugins as we add them.
- As already mentioned, this file is well commented and acts as the canonical documentation.
- examples/: Contains another demo that you can use as template for your first simple slide shows.
- src/: The main file is src/impress.js. Additional
functionality is implemented as plugins in src/plugins/.
- See src/plugins/README.md for information about the plugin API and how to write plugins.
- test/: Contains QUnit and Syn libraries that we use for writing tests, as well as some test coverage for core functionality. (Yes, more tests are much welcome.) Tests for plugins are in the directory of each plugin.
- js/: Contains js/impress.js, which contains a
concatenation of the core
src/impress.jsand all the plugins. Traditionally this is the file that you'll link to in a browser. In fact both the demo and test files do exactly that.
- [css/](css/]: Contains a CSS file used by the demo. This file is not required for using impress.js in your own presentations. Impress.js creates the CSS it needs dynamically.
- extras/ contains plugins that for various reasons aren't
enabled by default. You have to explicitly add them with their own
scriptelement to use them.
- build.js: Simple build file that creates
js/impress.js. It also creates a minified version
impress.min.js, but that one is not included in the github repository.
- package.json: An NPM package specification. This was mainly added
so you can easily install buildify
node build.js. Other than the build process (which is really just doing roughly
cat src/impress.js src/plugins/*/*.js > js/impress.js)
impress.jsitself doesn't depend on Node or any NPM modules.
- bower.json: A Bower package file. We also don't depend on Bower, but provide this file if you want to use it.
WANT TO CONTRIBUTE?
For developers, once you've made changes to the code, you should run these commands for testing:
npm run build npm run test npm run lint
Note that running
firefox qunit_test_runner.html is usually more informative than running
npm run test. They both run the same tests.
Upstream impress.js has its own bureacracy around contributing. I welcome pull requests against this fork as well, just submit a PR on github and I'll be happy to look at it :-)
Note that if, for example, you want to add a new plugin, you should do it against this fork, since upstream impress.js doesn't have a plugin API yet. Hopefully one day the progress from this fork will trickle back to upstream repository.
ABOUT THE NAME
impress.js name is courtesy of @skuzniak.
It's an (un)fortunate coincidence that a Open/LibreOffice presentation tool is called Impress ;)
See the Reference API
The typical use case for impress.js is to create presentations that you present from your own laptop, with a browser version you know works well. Some people also use impress.js successfully to embed animations or presentations in a web page, however, be aware that in this some of your visitors may not see the presentation correctly, or at all.
In particular, impress.js makes use of the following JS and CSS features:
