tinybind

tinybind is the espiritual sucessor of Rivets.js, a lightweight data binding and templating system that facilitates building data-driven views. It is agnostic about every aspect of a front-end MV(C|VM|P) stack, making it easy to introduce it into your current workflow or to use it as part of your own custom front-end stack comprised of other libraries.

Install

npm install tinybind

Use in a script tag...

<script src="node_modules/tinybind/dist/tinybind.js"></script>

... or import using a bundler like webpack

import tinybind from 'tinybind'

Usage

<section id="auction">
  <h3>{ auction.product.name }</h3>
  <p>Current bid: { auction.currentBid | money }</p>

  <aside rv-if="auction.timeLeft | lt 120">
    Hurry up! There is { auction.timeLeft | time } left.
  </aside>
</section>

tinybind.bind($('#auction'), {auction: auction})

Getting Started and Documentation

Documentation is available on the homepage. Learn by reading the Guide and refer to the Binder Reference to see what binders are available to you out-of-the-box.

Differences from Rivets.js

• Public interface
  • Uses web components specs instead of custom implementation
  • Implement computed feature using watch formatter instead of a specific syntax
  • Add not/negate builtin formatters
  • Remove unless and unchecked binders in favor of combining not/negate formatters with if/checked binders
  • Add ability to customize input event through event-name attribute
• Internal changes
  • Written in ES6 instead of coffeescript
  • Change how scope of iteration binder works. Instead of copying properties down to children, uses a prototype like approach
    • Related: 486 512 417
    • More info in the documentation
  • Change name of rv-each index property from index to $index
  • Change how to customize index name in each binder (using an attribute)
    • Related: 551 552
  • Do not bind publish, bind and unbind methods to binding instances
  • Register default binder through fallbackBinder option instead of * binder
  • Integrate sightglass into tinybind code base
  • Remove view.select method
  • Rename binding property args to arg and changed type from array to string
  • The rv-* attributes are removed after binding
  • Changes how observer is registered / notified. Instead of passing a function (sync), pass an object with a sync method

Building and Testing

First install any development dependencies.

$ npm install

Building

tinybind.js uses rollup as it's bundling / build tool. Run the following to compile the source into dist/.

$ npm run build

Testing

tinybind.js uses mocha as it's testing framework, alongside should for expectations and sinon for spies, stubs and mocks. Run the following to run the full test suite.

$ npm test

Building documentation

The documentation is built with harp which must be installed globally

$ cd docs
$ harp compile _harp ./

Contributing

Bug Reporting

1. Ensure the bug can be reproduced on the latest master.
2. Open an issue on GitHub and include an isolated JSFiddle demonstration of the bug. The more information you provide, the easier it will be to validate and fix.

Pull Requests

1. Fork the repository and create a topic branch.
2. Make sure not to commit any changes under dist/ as they will surely cause conflicts for others later. Files under dist/ are only committed when a new build is released.
3. Include tests that cover any changes or additions that you've made.
4. Push your topic branch to your fork and submit a pull request. Include details about the changes as well as a reference to related issue(s).
