About stepper

ng-hub-ui-stepper helps Angular applications structure onboarding, checkout and wizard-like forms. It gives teams a reusable way to control step progression, validation and navigation logic without baking those rules into each flow by hand.

Key features

Recent changes

Version 22.8.0 - 8/14/26, 12:00 AM

changed: Default action labels now resolve HUBUI.STEPPER.* before the legacy flat keys. The component provides the namespace through HUB_TRANSLATION_PREFIX, so an application dictionary can feed the built-in navigation labels via provideHubTranslationAdapter() without reserving generic top-level keys. Existing flat dictionaries keep working — the bare key is still the fallback.

added: README documentation for the application-wide translation adapter (provideHubTranslationAdapter() from ng-hub-ui-utils).

removed: Removed the @angular/animations peer dependency. The package is deprecated upstream and the library never used it. Applications that installed it only for ng-hub-ui-stepper can drop it.

Version 22.7.1 - 8/8/26, 12:00 AM

fixed: Documentation links now point at the canonical localized URLs. The README linked to https://hubui.dev/<path> with no locale prefix and no trailing slash, and both forms are 301-redirected, so every reader arriving from npm or GitHub landed on a redirect instead of the canonical page.

Version 22.7.0 - 7/29/26, 12:00 AM

added: --hub-stepper-indicator-size — the canonical step-indicator diameter (calc(var(--hub-ref-space-3, 1rem) * 2)). The built-in nav is text-only; this is the published metric custom trigger templates and companion step/lifecycle tracks read, space-derived so a density re-theme moves it with the paddings and font sizes that already scale.

Version 22.6.0 - 7/28/26, 12:00 AM

added: WAI-ARIA tablist semantics on the step rail: the rail is role="tablist" with aria-orientation, each trigger is role="tab" with aria-selected / aria-current="step" / aria-disabled, and each step content is a role="tabpanel" wired to its tab through stable generated ids.

added: Keyboard navigation on the rail with a roving tabindex (single Tab stop): Arrow keys move between enabled tabs (skipping disabled ones, wrapping), Home/End jump to the first/last enabled tab, and Enter/Space activates the focused step under the same permission model as clicking.

added: New railLabel input: accessible name of the step rail tablist (default 'Steps').

fixed: Default rail triggers now declare type="button", so a stepper rendered inside a <form> no longer submits it when a step trigger is clicked.

Version 22.5.1 - 7/26/26, 12:00 AM

fixed: StepTriggerDirective selector used a descendant combinator and never instantiated; it now matches either attribute and captures its TemplateRef (groundwork — the stepper does not render custom triggers yet).

changed: Declared the real ng-hub-ui-utils peer range (>=22.7.0); the previous >=1.2.0 floor allowed installs that fail at runtime.

Version 21.2.0 - 3/19/26, 12:00 AM

added: StepperAnimationDirection enum exported for typed animation direction values.

added: Step indexes are now automatically assigned by StepperComponent via a reactive effect — no manual [index] binding required.

changed: StepComponent.index is now an internal writable signal. Remove all [index]="N" bindings from hub-step templates.

changed: StepComponent.disabled simplified to a direct signal input (input(false)), removing the getter/setter and disabled$ backing signal.

changed: StepperComponent.currentIndex is now a writable signal — call as currentIndex() instead of the previous getter.

changed: Renamed internal signals: removed $ suffix from currentIndex, contentAnimating, animationDirection.

removed: StepComponent.disabled$ backing signal removed. Use the disabled signal input directly.

removed: [index] template binding removed from StepComponent — managed internally.

Version 21.1.0 - 3/18/26, 12:00 AM

added: Angular 21 support with Signals-based architecture.

added: contentChild and contentChildren for step and directive discovery.

changed: All components and directives converted to standalone.

fixed: Fixed step indices and validation during dynamic step additions.
