Release 1.0.0 - A New Hope · medialize/ally.js

November 18th 2015. We're embarking on a journey to make accessibility simpler. Version 1.0.0 - the official release - of ally.js has been 14 months in the making. But it's only the beginning of a long story - or so I hope.

The mission

Making accessibility simpler (for developers) by providing

providing core functionality (not complete solutions)
documentation to learn about accessibility requirements
the basis figure out how specifications need to evolve
a common ground for the community to collaborate

The plan

I've laid the foundation for collaboration. My goals are laid out. Everything is done on github, in the open. Everything is up for discussion. Anyone can join. See contributing to ally.js for more.

The past

Version 1.0.0 is a complete rewrite from the the early 0.0.x releases, there are no breaking changes, it is a giant breaking change. More than 400 commits have been made since 0.0.7, resulting in a few changes:

moving dependencies from bower to npm (in fact, abandoning bower altogether)
moving source from AMD to ES6 Module Syntax
unifying API of all functions, see the API docs
adding ES6 build infrastructure - issue #1
adding unit tests - issue #2 (>90% coverage!)
adding ally.query.firstTabbable (replacing focus/first) to find the first keyboard focusable element in a sub-tree
adding strategy: 'strict' option to ally.query.focusable to find elements by filters unavailable to querySelectorAll() - i.e. Shadow DOM without the "Shadow Piercing Descendant Combinator", scrollable containers, -webkit-user-modify: read-write - issue #17, issue #21
ally.query.focusable no longer considers <html> and <body> focusable - issue #31
adding ally.is.focusRelevant to identify technically focusable elements (refactored from ally.is.focusable)
adding ally.is.onlyTabbable to identify elements that cannot be focused by script, but by keyboard
adding ally.element.disabled (refactored from focus/disabled) - issue #33
adding ally.when.key to observe simple keyboard input - issue #47
adding ally.get.insignificantBranches to find branches not relevant to a given set of elements - issue #32
adding ally.maintain.hidden to hide everything in the DOM that is not relevant to a given set of elements - issue #46
fixing ally.is.visible by removing dimension constraint - issue #14
fixing ally.is.focusable to also identify "edge-cases" - issue #17, issue #20, issue #21

Breaking changes (compared to 0.0.7)

ally.js is no longer available through bower, other than by downloading the built archive
src/ was ES5 and AMD, it is now ES6. AMD modules are available in dist/amd/
dropping focus/first in favor of ally.query.firstTabbable
dropping focus/trap in favor of ally.maintain.disabled
ally.is.validArea (dom/is-valid-area) now returns false for elements that are not <area>
ally.is.validTabindex (dom/is-valid-tabindex) now returns false for elements without tabindex attribute
ally.style.focusSource has methods .next() and .repeat() removed
