Timerfrontend

Timerfrontend is a frontend library designed for building timer-based user interfaces in web applications. It provides a set of reusable UI components and a lightweight timer engine that can handle countdowns, elapsed timers, and interval timers. The project emphasizes accessibility, theming, and predictable rendering across environments.

The library features a small, framework-agnostic core that manages time state and event emissions, along with adapters or wrappers for popular frontend frameworks. The timer engine uses a high-precision approach driven by requestAnimationFrame or a fall-back on setInterval, and it exposes events for tick, pause, resume, and completion. This separation allows developers to swap UI layers while preserving reliable timing behavior.

Core components and capabilities include countdown timers, countup timers, interval timers with laps, start/pause/resume/reset controls, and time formatting utilities. Timerfrontend also provides built-in theming, localization options, and ARIA-compliant controls to support accessible interactions. Developers can extend functionality with plugin hooks or custom renderers, enabling integration with existing state management patterns or design systems.

Usage and ecosystem: Timerfrontend is typically installed via package managers and can be integrated directly into web projects. It offers adapters or components for common frameworks such as React, Vue, or Svelte, as well as a vanilla option for non-framework environments. Documentation and examples cover installation, configuration, and best practices for building consistent timer interfaces across applications.
