CHANGELOG.md

Changelog

All notable changes to this project are documented in this file. This project adheres to Semantic Versioning.

[v3.0.1]

FIXED

• Refactor away Array.prototype.findIndex in favour of Array.prototype.indexOf to reinstate IE 11 support without use of a polyfill (springload#237, springload#224).

[v3.0.0]

This release is the culmination of a massive amount of work, resulting in some new features and significantly stronger and more reliable WAI ARIA spec compliance. Notably, the project has been migrated from Flow to Typescript, and a full accessibility audit has been performed - revealing a few holes in our compliance which have now been entirely addressed.

Thanks to everyone who has contributed to this release - and not just those who have written code. Contribution by way of issues relating to spec compliance, pull-request commentary, advice and assistance is all greatly appreciated. Thanks also to the patient users who have endured an extended period without a release while we made sure to get this 100% right! Release cadence should return to normal again now.

Breaking Changes - Upgrade Guide:

1. Rename all of your AccordionItemTitle components to AccordionItemHeading and then nest an AccordionItemButton directly inside of each one. Note that in order for your Accordion to remain spec-compliant, you may not put any other children inside AccordionItemHeading.

   // Before:
   import { AccordionItemTitle } from 'react-accessible-accordion';
   
   const headingBefore = <AccordionItemTitle>Foo</AccordionItemTitle>;

   //  After:
   import {
       AcccordionItemHeading,
       AccordionItemButton,
   } from 'react-accessible-accordion';
   
   const headingAfter = (
       <AccordionItemHeading>
           <AccordionItemButton>Foo</AccordionItemButton>
       </AccordionItemHeading>
   );

2. Rename all of your AccordionItemBody components to AccordionItemPanel.

   // Before:
   import { AccordionItemBody } from 'react-accessible-accordion';
   
   const panelBefore = (
       <AccordionItemBody>
           Voluptate elit eiusmod laborum proident esse officia dolor laboris
           laboris amet nulla officia cillum.
       </AccordionItemBody>
   );

   // After:
   import { AccordionItemPanel } from 'react-accessible-accordion';
   
   const panelAfter = (
       <AccordionItemPanel>
           Voluptate elit eiusmod laborum proident esse officia dolor laboris
           laboris amet nulla officia cillum.
       </AccordionItemPanel>
   );

3. Remove all instances of hideBodyClassName. This prop is no longer valid, as AccordionItemPanel components are now hidden without additional styling. If you must have a different className prop when an item is collapsed, then you may leverage the new AccordionItemState component.

   // Before
   import { AccordionItemPanel } from 'react-accessible-accordion';
   
   const panelBefore = (
       <AccordionItemPanel className="foo" hideBodyClassName="foo--hidden" />
   );

   // After:
   import {
       AccordionItemPanel,
       AccordionItemState,
   } from 'react-accessible-accordion';
   
   const panelAfter = (
       <AccordionItemState>
           {({ expanded }) => (
               <AccordionItemPanel
                   className={expanded ? 'foo' : 'foo foo--hidden'}
               />
           )}
       </AccordionItemState>
   );

4. Remove all instances of AccordionItem’s expanded prop and instead use Accordion’s preExpanded prop. Note that this means that ‘controlled’ accordions are no longer a supported pattern. Please raise an issue if you have a use-case which calls for the ability to manually control expanded state.

   // Before
   import { Accordion, AccordionItem } from 'react-accessible-accordion';
   
   const accordionBefore = (
       <Accordion>
           <AccordionItem expanded />
       </Accordion>
   );

   // After:
   import { Accordion, AccordionItem } from 'react-accessible-accordion';
   
   const accordionAfter = (
       <Accordion preExpanded={['foo']}>
           <AccordionItem uuid="foo" />
       </Accordion>
   );

5. Remove all instances of Accordion’s accordion prop. Instead, use a combination of allowZeroExpanded and allowMultipleExpanded props to suit your requirements. If you were not explicitly setting accordion to false then you probably are not required to make any changes here.

   // Before
   import { Accordion } from 'react-accessible-accordion';
   
   const accordionBefore = <Accordion accordion={false} />;

   // After:
   import { Accordion } from 'react-accessible-accordion';
   
   const accordionAfter = <Accordion allowMultipleExpanded />;

6. Upgrade to React v16.3+

7. Remove your minimal-example.css import. These styles only applied display: none to panels when collapsed, but browsers apply these styles to elements with the hidden attribute, which the AccordionItemPanel component now has (when collapsed).

• Added AccordionItemState component.
• Added allowZeroExpanded prop to Accordion.
• Added allowMultipleExpanded prop to Accordion.

Changed

• Renamed AccordionItemTitle to AccordionItemHeading to be consistent with the language used in the WAI ARIA spec.

[v2.4.1]

Changed

• Upgraded a bunch of devDependencies, including Webpack which required a bit of a config refactor.

[v2.3.0]

Changed

[v2.2.1]

Changed

• Fixes mixed up filenames in the README

[v2.2.0]

Added

• Demo styles added to the bundle as two optional files:

  • fancy-example.css: 'Fancy' theme - boilerplate styles for all components, as seen on our demo

[v2.1.0]

Added

• Publish flow types.

Changed

• Upgrade all dev-dependencies except the eslint configs.

• Add specific assertions to tests in accordionStore.
• Minor syntax change in AccordionItemBody

[v2.0.0]

Version 2.0 represents a total refactor, with a new context-based approach which should make this library more flexible, more maintainable and more comprehensively testable.

As this is a major release, users should expect some breaking changes - though they should be limited to the removal of the activeItems prop (read more below).

Added

• Exports resetNextId (springload#41).

Fixed

• Defect where controlled components' props were overridden by React.Children.map (springload#33).
• Defect where accordion crashed with unexpected children types (springload#45).
• Defect where React Accessible Accordion's components could not be extended.
• Defect where the children of Accordion or AccordionItem could not be arbitrary.
• Defect where AccordionItem had to be a child of Accordion (as opposed to to an arbitrary-level descendant).
• Defect where AccordionItemBody and AccordionItemTitle had to be children of AccordionItem (as opposed to arbitrary-level descendants).

Removed:

• 🚨 Breaking change 🚨 activeItems property is no longer supported.

Control at the Accordion level (via the activeItems prop) and AccordionItem level (via the expanded prop) fought against one another, and choosing which control mechanism to give preference to would have been an arbitrary decision - and whichever way we went, we would have had test cases which demonstrated unusual/unpredictable behaviour. The activeItems mechanism was the obvious one to remove - it was arguably the "less React-y way", and we considered it more of a convenience than a feature. Crucially though, it fought too hard against the new architecture of the library, and keeping it would have prevented us enabling lots of other new features or resolving some of the issues that our users had raised.

If you're currently using activeItems, you're upgrade path might look like this:

const items = ['Foo', 'Bar'];
const activeItems = [0];

return (
-    <Accordion activeItems={activeItems} />
+    <Accordion />
        {activeItems.forEach((item, i) => (
-            <AccordionItem key={item}>{item}</AccordionItem>
+            <AccordionItem key={item} expanded={activeItems.includes(i)}>{item}</AccordionItem>
        )}
    </Accordion>
);
