Ractive.js - Next-generation DOM manipulation

Got questions? Tag Stack Overflow questions with ractivejs or contact @RactiveJS on Twitter

What is Ractive.js?

It's a JavaScript library for building reactive user interfaces in a way that doesn't force you into a particular framework's way of thinking. Its features include...

• data-binding, with a beautiful declarative syntax
• event handling that doesn't make you tear your hair out
• flexible and performant animations and transitions

...among many others. It takes a radically different approach to DOM manipulation - one that saves both you and the browser unnecessary work.

To get a feel for how it will make your life as a web developer easier, visit ractivejs.org, follow the interactive tutorials, or try the 60 second setup.

Developing and building

If you want to hack on Ractive, the first step is to clone the repo and install all its development dependencies:

git clone https://github.com/ractivejs/ractive   # or your fork
cd ractive
npm install

While developing the library, you can serve it with gobble:

npm start

Navigate to localhost:4567 - you'll see two folders, plus ractive.js:

• sandbox - this contains some template files to help with debugging. Start by copying the sandbox/sample folder and following the instructions therein
• test - the test suite (duh)

After the initial build, any subsequent changes will result in fast incremental rebuilds. If you're using Chrome, you can use the LiveReload plugin.

Gobble is still in development - please report any bugs to the issue tracker - thanks!

To run a complete build (including linting, testing and minification):

npm run build

Distribution build requirements

• A real shell, so Linux and OS X should be good. Windows needs MSYS or something similar at least on the path.
• On Windows, if you get an EINVAL when running the tests, you may need to update the phantomjs script in the node_modules/.bin to use { stdio: 'inherit' } when spawning the child process instead of manually piping afterwards.

Contributing

Pull requests and issues are always welcome! Please read CONTRIBUTING.md to learn how to contribute.

Reporting security vulnerabilities

If you think you've found a security vulnerability, please email ractive-js-security@googlegroups.com with details, and someone from the core team will respond to you.

Browser support

Tested successfully in IE8+ and all modern browsers. If your experience differs please let me know! (For legacy browser support, use the builds with legacy in the filename - these include polyfills for Array.prototype.forEach and other ES5 features used by Ractive.)
