A headless Svelte library for building animated multi-step flows with full control over layout and transitions.
Svelte Stepper is a library for creating animated, multi-step flows in Svelte applications. It provides a headless architecture that handles navigation, animations, and state management while allowing developers to define custom step components. This solves the problem of building complex user journeys like multi-step forms, onboarding sequences, or interactive wizards without imposing design decisions.
Svelte developers building applications that require multi-step user flows, such as complex forms, onboarding processes, or interactive wizards. It's particularly suited for those who need full control over step layout and styling.
Developers choose Svelte Stepper for its headless approach that provides navigation logic while letting them control step layout, styles, and transitions. Its unique selling points include built-in TypeScript support, automatic height-adjusting animations, a context API for multi-step forms, and side-step functionality for temporary flow diversions.

Provides full control over step layout and styling, as the library steps through whatever components you give it without imposing design decisions, ideal for custom implementations.
Built entirely in TypeScript with fully typed interfaces for step components and props, ensuring type safety out of the box and reducing runtime errors.
Transitions steps smoothly with adjustable height and customizable transition functions, as shown in the demo with sleek default animations.
Includes a context API using Svelte writable stores to share data across steps, enabling advanced use cases like multi-step form data collection.
Supports temporary diversion to different step sequences and return, allowing complex flow management without breaking the main journey, as detailed in the sidestep section.
Being headless, it requires developers to design and style every step from scratch, which can be time-consuming and resource-intensive for teams lacking CSS expertise.
Tied exclusively to Svelte, making it unsuitable for projects using other frameworks or those considering future migration, limiting its versatility.
Customizing transitions requires familiarity with Svelte's transition functions and parameters, which adds a learning curve and potential for errors in complex animations.
