Changelog

Shoelace follows Semantic Versioning. Breaking changes in components with the Stable badge will not be accepted until the next major version. As such, all contributions must consider the project’s roadmap and take this into consideration. Features that are deemed no longer necessary will be deprecated but not removed.

Components with the Experimental badge should not be used in production. They are made available as release candidates for development and testing purposes. As such, changes to experimental components will not be subject to semantic versioning.

New versions of Shoelace are released as-needed and generally occur when a critical mass of changes have accumulated. At any time, you can see what’s coming in the next release by visiting next.shoelace.style.

I’d like to extend a very special thank you to every single contributor who worked to make this possible. Everyone who’s filed a bug, submitted a PR, requested a feature, started a discussion, helped with testing, and advocated for the project. You are just as responsible for Shoelace’s success as I am.

2.0.0-beta.80

This release breaks radio buttons, which is something that needed to happen to solve a longstanding accessibility issue where screen readers announced an incorrect number of radios, e.g. “1 of 1” instead of “1 of 3.” Many attempts to solve this without breaking the existing API were made, but none worked across the board. The new implementation upgrades <sl-radio-group> to serve as the “form control” while <sl-radio> and <sl-radio-button> serve as options within the form control.

To upgrade to this version, you will need to rework your radio controls by moving name up to the radio group. And instead of setting checked to select a specific radio, you can set value on the radio group and the checked item will update automatically.

2.0.0-beta.61

This release improves the dark theme by shifting luminance in both directions, slightly condensing the spectrum. This results in richer colors in dark mode. It also reduces theme stylesheet sizes by eliminating superfluous gray palette variations.

In beta.48, I introduced a change to color tokens that allowed you to access alpha values at the expense of a verbose, non-standard syntax. After considering feedback from the community, I’ve decided to revert this change so the rgb() function is no longer required. Many users reported never using it for alpha, and even more reported having trouble remembering to use rgb() and that it was causing more harm than good.

Furthermore, both Safari and Firefox have implemented color-mix() behind a flag, so access to alpha channels and other capabilities are coming to the browser soon.

If you’re using color tokens in your own stylesheet, simply remove the rgb() to update to this version.

.your-styles {
  /* change this */
  color: rgb(var(--sl-color-primary-500));

  /* to this */
  color: var(--sl-color-primary-500);
}

Thank you for your help and patience with testing Shoelace. I promise, we’re not far from a stable release!

2.0.0-beta.58

This version once again restores the bundled distribution because the unbundled + CDN approach is currently confusing and not working properly. Unbundling the few dependencies Shoelace has is still a goal of the project, but this jsDelivr bug needs to be resolved before we can achieve it.

I sincerely apologize for the instability of the last few beta releases as a result of this effort.

• Added experimental <sl-animated-image> component

• Updated to Bootstrap Icons to 1.6.1

2.0.0-beta.57

• Fix CodePen links and CDN links

2.0.0-beta.56

This release is the second attempt at unbundling dependencies. This will be a breaking change only if your configuration does not support bare module specifiers. CDN users and bundler users will be unaffected, but note the URLs for modules on the CDN must have the /+esm now.

• Added the hoist attribute to <sl-tooltip> #564
• Unbundled dependencies and configured external imports to be packaged with bare module specifiers

2.0.0-beta.55

• Revert unbundling due to issues with the CDN not handling bare module specifiers as expected

2.0.0-beta.54

Shoelace doesn’t have a lot of dependencies, but this release unbundles most of them so you can potentially save some extra kilobytes. This will be a breaking change only if your configuration does not support bare module specifiers. CDN users and bundler users will be unaffected.

• 🚨 BREAKING: renamed the sl-clear event to sl-remove, the clear-button part to remove-button, and the clearable property to removable in <sl-tag>

2.0.0-beta.51

A number of users had trouble counting characters that repeat, so this release improves design token patterns so that “t-shirt sizes” are more accessible. For example, --sl-font-size-xxx-large has become --sl-font-size-3x-large. This change applies to all design tokens that use this scale.

• 🚨 BREAKING: all t-shirt size design tokens now use 2x, 3x, 4x instead of xx, xxx, xxxx
• Added missing --sl-focus-ring-* tokens to dark theme
• Added an “Importing” section to all components with copy/paste code to make cherry picking easier

• Fixed a bug where form controls would error out when the value was set to undefined #513

2.0.0-beta.49

This release changes the way focus states are applied to elements. In browsers that support :focus-visible, it will be used. In unsupportive browsers (currently only Safari), :focus will be used instead. This means the browser will determine whether a focus ring should be shown based on how the user interacts with the page.

This release also fixes a critical bug in the color scale where --sl-color-neutral-0 and --sl-color-neutral-1000 were reversed.

• 🚨 BREAKING: fixed a bug where --sl-color-neutral-0 and --sl-color-neutral-1000 were inverted (swap them to update)
• 🚨 BREAKING: removed the no-fieldset property from <sl-radio-group> (fieldsets are now hidden by default; use fieldset to show them)
• 🚨 BREAKING: removed --focus-ring custom property from <sl-input>, <sl-select>, <sl-tab> for consistency with other form controls
• Added --swatch-size custom property to <sl-color-picker>
• Added date to <sl-input> as a supported type
• Added the --sl-focus-ring design token for a more convenient way to apply focus ring styles

• Updated to Lit 2.0.0-rc.3
• Updated to lit-html 2.0.0-rc.4

2.0.0-beta.48

This release improves theming by offering both light and dark themes that can be used autonomously. It also improves contrast in most components, adds a variety of new color primitives, and changes the way color tokens are consumed.

Previously, color tokens were in hexadecimal format. Now, Shoelace now uses an R G B format that requires you to use the rgb() function in your CSS.

.example {
  /* rgb() is required now */
  color: var(--sl-color-neutral-500);
}

This is more verbose than previous versions, but it has the advantage of letting you set the alpha channel of any color token.

.example-with-alpha {
  /* easily adjust opacity for any color token */
  color: rgb(var(--sl-color-neutral-500) / 50%);
}

This change applies to all design tokens that implement a color. Refer to the color tokens page for more details.

• 🚨 BREAKING: all design tokens that implement colors have been converted to R G B and must be used with the rgb() function
• 🚨 BREAKING: removed --sl-color-black|white color tokens (use --sl-color-neutral-0|1000 instead)
• 🚨 BREAKING: removed --sl-color-primary|success|warning|info|danger-text design tokens (use theme or primitive colors instead)
• 🚨 BREAKING: removed info variant from <sl-alert>, <sl-badge>, <sl-button>, and <sl-tag> (use neutral instead)
• 🚨 BREAKING: removed --sl-color-info-* design token (use --sl-color-neutral-* instead)
• 🚨 BREAKING: renamed dist/themes/base.css to dist/themes/light.css
• 🚨 BREAKING: removed --sl-focus-ring-color-primary tokens (use color tokens and --sl-focus-ring-width|alpha instead)
• 🚨 BREAKING: removed --tabs-border-color from <sl-tab-group> (use --track-color instead)
• 🚨 BREAKING: changed the default value for effect to none in <sl-skeleton> (use sheen to restore the original behavior)
• Added new color primitives to the base set of design tokens
• Added --sl-color-*-950 swatches to all color palettes
• Added a console error that appears when menu items have duplicate values in <sl-select>
• Added CodePen link to code examples
• Added prefix and suffix slots to <sl-select> #501
• Added --indicator-color custom property to <sl-tab-group>
• Exposed base and dark stylesheets so they can be imported via JavaScript #438
• Fixed a bug in <sl-menu> where pressing Enter after using type to select would result in the wrong value
• Fixed a bug in <sl-radio-group> where clicking a radio button would cause the wrong control to be focused
• Fixed a bug in <sl-button> and <sl-icon-button> where an unintended ref attribute was present
• Fixed a bug in the focus-visible utility that failed to respond to mouseup events
• Fixed a bug where clicking on a menu item would persist its hover/focus state
• Fixed a bug in <sl-select> where it would erroneously intercept important keyboard shortcuts #504
• Improved contrast throughout all components #128
• Refactored thumb position logic in <sl-switch> #490
• Reworked the dark theme to use an inverted + shifted design token approach instead of component-specific selectors

2.0.0-beta.47

This release improves how component dependencies are imported. If you’ve been cherry picking, you no longer need to import component dependencies manually. This significantly improves developer experience, making Shoelace even easier to use. For transparency, component dependencies will continue to be listed in the docs.

• Added “Reflects” column to the properties table
• Dependencies are now automatically imported for all components
• Fixed a bug where tabbing into <sl-radio-group> would not always focus the checked radio
• Fixed a bug in component styles that prevented the box sizing reset from being applied
• Fixed a regression in <sl-color-picker> where dragging the grid handle wasn’t smooth
• Fixed a bug where slot detection could incorrectly match against slots of child elements #481
• Fixed a bug in <sl-input> where focus would move to the end of the input when typing in Safari #480
• Improved base path utility logic

2.0.0-beta.46

This release improves the developer experience of <sl-animation>. Previously, an animation was assumed to be playing unless the pause attribute was set. This behavior has been reversed and pause has been removed. Now, animations will not play until the new play attribute is applied.

This is a lot more intuitive and makes it easier to activate animations imperatively. In addition, the play attribute is automatically removed automatically when the animation finishes or cancels, making it easier to restart finite animations. Lastly, the animation’s timing is now accessible through the new currentTime property instead of getCurrentTime() and setCurrentTime().

In addition, Shoelace no longer uses Sass. Component styles now use Lit’s template literal styles and theme files use pure CSS.

• 🚨 BREAKING: removed the pause attribute from <sl-animation> (use play to start and stop the animation instead)
• 🚨 BREAKING: removed getCurrentTime() and setCurrentTime() from <sl-animation> (use the currentTime property instead)
• 🚨 BREAKING: removed the close-on-select attribute from <sl-dropdown> (use stay-open-on-select instead)
• Added the currentTime property to <sl-animation> to control the current time without methods
• Fixed a bug in <sl-range> where the tooltip wasn’t showing in Safari #477
• Fixed a bug in <sl-menu> where pressing Enter in a menu didn’t work with click handlers
• Reworked <sl-menu> and <sl-menu-item> to use a roving tab index and improve keyboard accessibility
• Reworked tabbable logic to be more performant #466
• Switched component stylesheets from Sass to Lit’s template literal styles
• Switched theme stylesheets from Sass to CSS

2.0.0-beta.45

This release changes the way component metadata is generated. Previously, the project used TypeDoc to analyze components and generate a very large file with type data. The data was then parsed and converted to an easier-to-consume file called metadata.json. Alas, TypeDoc is expensive to run and the metadata format wasn’t standard.

Thanks to an amazing effort by Pascal Schilp, the world has a simpler, faster way to gather metadata using the Custom Elements Manifest Analyzer. Not only is this tool faster, but the data follows the evolving custom-elements.json format. This is exciting because a standard format for custom elements opens the door for many potential uses, including documentation generation, framework adapters, IDE integrations, third-party uses, and more. Check out Pascal’s great article for more info about custom-elements.json and the new analyzer.

The docs have been updated to use the new custom-elements.json file. If you’re relying on the old metadata.json file for any purpose, this will be a breaking change for you.

• 🚨 BREAKING: removed the sl-overlay-click event from <sl-dialog> and <sl-drawer> (use sl-request-close instead) #471
• 🚨 BREAKING: removed metadata.json (use custom-elements.json instead)
• Added custom-elements.json for component metadata
• Added sl-request-close event to <sl-dialog> and <sl-drawer>
• Added dialog.denyClose and drawer.denyClose animations
• Fixed a bug in <sl-color-picker> where setting value immediately wouldn’t trigger an update
• Fixed a bug in <sl-dialog> and <sl-drawer> where setting open initially didn’t set a focus trap
• Fixed a bug that resulted in form controls having incorrect validity when disabled was initially set #473
• Fixed a bug in the docs that caused the metadata file to be requested twice
• Fixed a bug where tabbing out of a modal would cause the browser to lag #466
• Updated the docs to use the new custom-elements.json for component metadata

2.0.0-beta.44

• 🚨 BREAKING: all invalid props on form controls now reflect validity before interaction #455
• Allow null to be passed to disable animations in setDefaultAnimation() and setAnimation()
• Converted build scripts to ESM
• Fixed a bug in <sl-checkbox> where invalid did not update properly
• Fixed a bug in <sl-dropdown> where a keydown listener wasn’t cleaned up properly
• Fixed a bug in <sl-select> where sl-blur was emitted prematurely #456
• Fixed a bug in <sl-select> where no selection with multiple resulted in an incorrect value #457
• Fixed a bug in <sl-select> where sl-change was emitted immediately after connecting to the DOM #458
• Fixed a bug in <sl-select> where non-printable keys would cause the menu to open
• Fixed a bug in <sl-select> where invalid was not always updated properly
• Reworked the @watch decorator to use update instead of updated resulting in better performance and flexibility

2.0.0-beta.43

• Added ? to optional arguments in methods tables in the docs
• Added the scrollPosition() method to <sl-textarea> to get/set scroll position
• Added initial tests for <sl-dialog>, <sl-drawer>, <sl-dropdown>, and <sl-tooltip>
• Fixed a bug in <sl-tab-group> where scrollable tab icons were not displaying correctly
• Fixed a bug in <sl-dialog> and <sl-drawer> where preventing clicks on the overlay no longer worked as described #452
• Fixed a bug in <sl-dialog> and <sl-drawer> where setting initial focus no longer worked as described #453
• Fixed a bug in <sl-card> where the slotchange listener wasn’t attached correctly #454
• Fixed lifecycle bugs in a number of components #451
• Removed fill: both from internal animate utility so styles won’t “stick” by default #450

2.0.0-beta.42

This release addresses an issue with the open attribute no longer working in a number of components, as a result of the changes in beta.41. It also removes a small but controversial feature that complicated show/hide logic and led to a poor experience for developers and end users.

There are two ways to show/hide affected components: by calling show() | hide() and by toggling the open prop. Previously, it was possible to call event.preventDefault() in an sl-show | sl-hide handler to stop the component from showing/hiding. The problem becomes obvious when you set el.open = false, the event gets canceled, and in the next cycle el.open has reverted to true. Not only is this unexpected, but it also doesn’t play nicely with frameworks. Additionally, this made it impossible to await show() | hide() since there was a chance they’d never resolve.

Technical reasons aside, canceling these events seldom led to a good user experience, so the decision was made to no longer allow sl-show | sl-hide to be cancelable.

• 🚨 BREAKING: sl-show and sl-hide events are no longer cancelable
• Added Iconoir example to the icon docs
• Added Web Test Runner
• Added initial tests for <sl-alert> and <sl-details>
• Changed the cancelable default to false for the internal @event decorator
• Fixed a bug where toggling open stopped working in <sl-alert>, <sl-dialog>, <sl-drawer>, <sl-dropdown>, and <sl-tooltip>

• Updated esbuild to 0.12.4

2.0.0-beta.41

This release changes how components animate. In previous versions, CSS transitions were used for most show/hide animations. Transitions are problematic due to the way transitionend works. This event fires once per transition, and it’s impossible to know which transition to look for when users can customize any possible CSS property. Because of this, components previously required the opacity property to transition. If a user were to prevent opacity from transitioning, the component wouldn’t hide properly and the sl-after-show|hide events would never emit.

CSS animations, on the other hand, have a more reliable animationend event. Alas, @keyframes don’t cascade and can’t be injected into a shadow DOM via CSS, so there would be no good way to customize them.

The most elegant solution I found was to use the Web Animations API, which offers more control over animations at the expense of customizations being done in JavaScript. Fortunately, through the Animation Registry, you can customize animations globally and/or per component with a minimal amount of code.

2.0.0-beta.34

This release changes the way components are registered if you’re cherry picking or using a bundler. This recommendation came from the LitElement team and simplifies Shoelace’s dependency graph. It also eliminates the need to call a register() function before using each component.

From now on, importing a component will register it automatically. The caveat is that bundlers may not tree shake the library properly if you import from @shoelace-style/shoelace, so the recommendation is to import components and utilities from their corresponding files instead.

• 🚨 BREAKING: removed all.shoelace.js (use shoelace.js instead)
• 🚨 BREAKING: component modules now have a side effect, so bundlers may not tree shake properly when importing from @shoelace-style/shoelace (see the installation page for more details and how to update)
• Added sl-clear event to <sl-select>
• Fixed a bug where dynamically changing menu items in <sl-select> would cause the display label to be blank #374

• Fixed the margin in <sl-menu-label> to align with menu items
• Fixed autofocus attributes in <sl-input> and <sl-textarea>
• Improved types for autocapitalize in <sl-input> and <sl-textarea>
• Reverted the custom @tag decorator in favor of @customElement to enable auto-registration

• Fixed a bug where the active tab indicator wouldn’t render properly on tabs styled with flex-end #355
• Fixed a bug where sl-change wasn’t emitted by <sl-checkbox> or <sl-switch> #370
• Fixed a bug where some props weren’t being watched correctly in <sl-alert> and <sl-color-picker>
• Improved @watch decorator so watch handlers don’t run before the first render
• Removed guards that were added due to previous watch handler behavior

2.0.0-beta.31

• Add touch support to <sl-rating> #362

2.0.0-beta.30

• Fix default exports for all components so cherry picking works again #365
• Revert FOUC base style because it interferes with some framework and custom element use cases

2.0.0-beta.29

This release migrates component implementations from Shoemaker to LitElement. Due to feedback from the community, Shoelace will rely on a more heavily tested library for component implementations. This gives you a more solid foundation and reduces my maintenance burden. Thank you for all your comments, concerns, and encouragement! Aside from that, everything else from beta.28 still applies plus the following.

• 🚨 BREAKING: removed the symbol property from <sl-rating> and reverted to getSymbol for optimal flexibility
• Added vscode.html-custom-data.json to the build to support IntelliSense (see the usage section for details)
• Added a base style to prevent FOUC before components are defined
• Fixed bug where TypeScript types weren’t being generated #364
• Improved vertical padding in <sl-tooltip>
• Moved chunk files into a separate folder
• Reverted menu item active styles
• Updated esbuild to 0.8.54

2.0.0-beta.28

This release includes a major under the hood overhaul of the library and how it’s distributed. Until now, Shoelace was developed with Stencil. This release moves to a lightweight tool called Shoemaker, a homegrown utility that provides declarative templating and data binding while reducing the boilerplate required for said features.

This change in tooling addresses a number of longstanding bugs and limitations. It also gives us more control over the library and build process while streamlining development and maintenance. Instead of two different distributions, Shoelace now offers a single, standards-compliant collection of ES modules. This may affect how you install and use the library, so please refer to the installation page for details.

The component API remains the same except for the changes noted below. Thanks for your patience as I work diligently to make Shoelace more stable and future-proof. 🙌

• 🚨 BREAKING: removed the custom elements bundle (you can import ES modules directly)
• 🚨 BREAKING: removed getAnimationNames() and getEasingNames() methods from <sl-animation> (you can import them from utilities/animation.js instead)
• 🚨 BREAKING: removed the <sl-icon-library> component since it required imperative initialization (you can import the registerIconLibrary() function from utilities/icon-library.js instead)
• 🚨 BREAKING: removed the experimental <sl-theme> component due to technical limitations (you should set the sl-theme-{name} class on the <body> instead)
• 🚨 BREAKING: moved the base stylesheet from dist/shoelace.css to dist/themes/base.css
• 🚨 BREAKING: moved icons into assets/icons to make future assets easier to colocate
• 🚨 BREAKING: changed getSymbol property in <sl-rating> to symbol (it now accepts a string or a function that returns an icon name)
• 🚨 BREAKING: renamed setAssetPath() to setBasePath() and added the ability to set the library’s base path with a data-shoelace attribute (setBasePath() is exported from utilities/base-path.js)
• Fixed min and max types in <sl-input> to allow numbers and strings #330
• Fixed a bug where <sl-checkbox>, <sl-radio>, and <sl-switch> controls would shrink with long labels #325

• Fixed a bug where scroll anchoring caused undesirable scrolling when <sl-details> are grouped

Shoelace events were updated to use a lowercase, kebab-style naming convention. Instead of event names such as slChange and slAfterShow, you’ll need to use sl-change and sl-after-show now.

This change was necessary to address a critical issue in frameworks that use DOM templates with declarative event bindings such as <sl-button @slChange="handler">. Due to HTML’s case-insensitivity, browsers translate attribute names to lowercase, turning @slChange into @slchange, making it impossible to listen to slChange.

While declarative event binding is a non-standard feature, not supporting it would make Shoelace much harder to use in popular frameworks. To accommodate those users and provide a better developer experience, we decided to change the naming convention while Shoelace is still in beta.

The following pages demonstrate why this change was necessary.
