Alpaca is the Easy Forms Engine for jQuery and Twitter Bootstrap.
It is built around JSON schema to keep things simple. Using Alpaca, you can express your forms object model, types, properties and validation logic. Forms rendered with Alpaca provide intuitive interfaces for your users while giving your business an assurance of data compliance.
Alpaca comes pre-configured to work nicely with the following web frameworks:
- jQuery
- Twitter Bootstrap
- jQuery UI
- jQuery Mobile
- Barebones (empty CSS)
The Alpaca library is pre-packaged with controls, wizards, layouts, I18N support and pluggable template engines. We ship with support for jQuery Tmpl, EJS and Handlebars. Documentation and API information is provided so that you can extend Alpaca as you see fit.
The philosophy behind Alpaca is that you should design your forms once and have them work on lots of different devices and UI engines without recoding. Here is a sample registration form written once and rendered using four different approaches:
Alpaca is an community-led open-source project licensed under Apache 2.0.
For information about the Alpaca Project, visit its home page at http://www.alpacajs.org.
We've collected videos, tutorials, API documentation and much more to help you get started.
Alpaca is compatible with jQuery 1.8.x and jQuery 1.9.x.
If you have a question about Alpaca, please visit the Alpaca Forums.
This is a place where we encourage the community and developer community to get together to support one another in their Alpaca-related projects.
In the spirit of open source software development, Alpaca always encourages community code contributions.
In order to build Alpaca, you need to have Apache Ant installed on your machine. Ant executes a build script
(build.xml) to assemble the Alpaca build products.
First, clone a copy of the Alpaca git repo by running:
git clone git://github.com/gitana/alpaca.git
Make sure you have Apache Ant installed by testing:
ant -version
You can then build Alpaca by running:
ant clean package
The built version of Alpaca will be put in the build/package subdirectory. This directory contains the Alpaca web site
(the same site that is deployed to http://www.alpacajs.org) along with all of the build
products. These build products include:
The assets you need to reference for the built version of Alpaca are these:
- /js/alpaca.js
- /css
The alpaca.js file contains all of the basic and advanced fields. If you only want the basic fields, you can reference the
alpaca-core.js file instead.
The build also produces two ZIP files which contain all of the assets.
- /downloads/alpaca.zip
- /downloads/alpaca-basic.zip (just the basic fields)
If you're using AMD to include Alpaca, the AMD files are located in:
- /components/alpaca (all fields)
- /components/alpaca-core (just the basic fields)
- /components/alpaca-extra (just the advanced fields)
The unit tests are written using QUnit and are located in the build/package/tests directory.
You will need to run them using your web browser but in order to do that, you first need to mount
the build/package directory into your web server. The Ant script provides a helper target to
let you do this.
First, create a file called custom-local.properties in the root of your Alpaca project. In it, define a single
property that points to the destination where you would like your Alpaca build directory to be copied. This should be
a virtual directory under your web server.
Here is an example:
local.docroot.basepath=/var/www
Then, run the following:
ant full
This will build Alpaca and copy the resulting assets to /var/www/alpaca. If you've set up /var/www as the docroot
for your web server, you can run the QUnit tests by opening a web browser and pointing to:
http://localhost/alpaca/tests/index.html
Alpaca works with any backend HTTP service. There is a connector layer and you can plug in your own persistence for forms, schema, options and layout.
Alpaca works out-of-the-box with Cloud CMS. Cloud CMS is a cost-effective backend content management system for mobile and web applications. If you're looking for a quick way to capture and report on forms, please consider checking it out.
If you have any questions, please feel free to submit and issue or ask on the Alpaca Discussion Forums.
