Technway Component Library

Repeatedly implementing buttons, form fields, cards, navigation, feedback states, and responsive layouts creates more than visual duplication. Small differences in properties, events, keyboard behavior, validation, and spacing make integration and maintenance harder across products.

The library also needed to work beyond one React application. Components had to preserve a clear API as native web components, React wrappers, and Next.js integrations, including server-rendering and hydration concerns.

The challenge was therefore to build a flexible system with useful defaults, documented extension points, and a release process, while avoiding a library so abstract that it became harder to use than rebuilding the interface locally.

• Reusable component contracts. Define narrow responsibilities, typed properties, events, slots, validation states, and predictable interaction behavior.
• Cross-framework delivery. Keep the Stencil implementation as the source while exposing supported React and Next.js packages.
• Visible documentation. Provide Storybook stories, generated API references, usage material, and integration examples.
• Maintainable releases. Organize the work as a pnpm and Lerna monorepo with package versioning and controlled release workflows.

• Design-system planning and component inventory.
• Component API design for props, events, methods, slots, and validation behavior.
• Stencil and TypeScript implementation across foundational and composed components.
• React and Next.js package integration, including SSR and hydrate support.
• Storybook configuration, generated documentation, examples, and RTL preview support.
• Accessibility review, responsive behavior, issue workflows, and package-release planning.

1. Start from repeated product patterns. Existing interface needs were grouped into foundations, form controls, navigation, content, feedback, media, and layout rather than collecting unrelated components.
2. Define the contract before styling. Each component was shaped around typed properties, events, methods, slots, states, and a limited responsibility so consumers know what remains stable.
3. Separate the core from framework adapters. Stencil owns the web components, while generated React and Next.js packages translate the same source into framework-specific consumption patterns.
4. Treat documentation and delivery as product work. Storybook, generated API files, example projects, issue templates, versioning, and publishing workflows live in the same repository.

• Component core. The Stencil package contains 34 Shadow DOM components, from headings, buttons, inputs, and alerts to headers, footers, navigation, carousels, and portfolio grids.
• Framework packages. React wrappers and a dedicated Next.js package allow the same component contract to be consumed in client-rendered and server-rendered applications.
• Layout foundation. A separate layout-kit package provides responsive grid utilities and a React Grid API instead of forcing layout concerns into every component.
• Documentation surface. The repository includes one Storybook story for each component, generated component statistics and API documentation, MDX usage material, RTL preview tooling, and React and Next.js example projects.

The source shows accessibility treated as a default component concern through semantic elements, visible focus behavior, keyboard interaction, labels, validation feedback, touch-target considerations, and reduced-motion handling where relevant. Storybook includes the accessibility addon, and the component documentation describes accessible behavior for key controls.

The repository snapshot does not include a formal WCAG conformance report, so the case study should describe the implemented practices without claiming complete compliance.

The library uses native web components and Shadow DOM, supports targeted package imports, and includes a hydrate output for server-rendered Next.js use. Shared CSS utilities and a separate layout package reduce the need to duplicate the same foundations in every application.

No verified bundle comparison or production Core Web Vitals study is included in the supplied repository, so performance is presented as an architectural objective rather than a measured business result.

The repository includes Storybook interaction and accessibility tooling, Jest and Stencil test commands, Playwright configuration, component validation scripts, and GitHub Actions that run on Windows and Ubuntu before release versioning.

The supplied snapshot contains 34 stories and extensive generated documentation, but only limited automated component test files. That is an important engineering limitation and a clear area for future work rather than something the portfolio should hide.

• Documented component system. The repository contains 34 components with a generated API surface of 357 props, 35 events, 6 methods, and 58 slots.
• Multiple consumption paths. Stencil, React, Next.js, and layout packages are maintained within one pnpm workspace, supported by React and Next.js example applications.
• Repeatable maintenance. Component stories, API generation, issue templates, changelogs, versioning, and package publishing workflows keep implementation and delivery decisions visible.
• Honest internal product. The project demonstrates a substantial reusable system while keeping claims about adoption, automated coverage, and measured speed improvements within the evidence available in the repository.

• A useful component library is built from repeated product needs, not from maximizing the number of components. Each API should stay narrow enough to understand while allowing deliberate extension.
• Cross-framework support makes component contracts more important. Ambiguous properties or hidden behavior become harder to maintain once the same component is consumed through native web components, React, and Next.js.
• Documentation and release automation are necessary, but they do not replace automated behavioral tests. Stronger test coverage should grow alongside the component catalog.
• Design systems remain useful when accessibility, responsive behavior, ownership, and deprecation decisions are treated as ongoing engineering work.
