Svelte-MiniApps: A Collection of Single-Purpose Svelte 5 Applications

Source: Dev.to

Overview

Sometimes you just need a simple tool to do one thing well. That’s the philosophy behind Svelte‑MiniApps.
The project is an open‑source collection of small, single‑purpose Svelte 5 applications. It started as an experiment with SvelteKit and has evolved into a robust set of utilities, fully updated for Svelte 5 in 2025.

Project Structure

• One repository, one website – all mini‑apps live together. You don’t install each tool separately; you run the app and navigate to the mini‑tool you need.
• Each mini‑app is a separate page/route with a small surface area, allowing independent iteration, quick onboarding for contributors, and safe refactoring.

Benefits

• Lightweight – Svelte’s compile‑time focus keeps the overall site fast and resource‑friendly.
• Lean dependencies – Avoids shipping heavyweight UI libraries when they aren’t needed.
• Educational – Shows real‑world Svelte 5 patterns: folder layout, state management, UI composition, and readability.

Purposes

1. Utility – Provides useful tools for everyday tasks (e.g., calculators, converters, simple tracking tools). See the repository for the latest list.
2. Education – Serves as a reference for modern Svelte 5 development. Explore the code to learn:
   • Folder layout
   • State patterns
   • The latest runes system
   • Component composition

Getting Started

1. Browse the repo and pick a mini‑app that matches what you’re trying to learn.
2. Read it end‑to‑end (they’re intentionally small).
3. Tweak a behavior and observe how the change flows through the app.
4. Apply the patterns you like to your own projects.

Contributing

Svelte‑MiniApps is open source! Contributions are welcome, especially for:

• Improving copy or empty states
• Adding tests or simple validation
• Tightening accessibility
• Reducing bundle size or unnecessary dependencies

Good starter contributions tend to be small and have an immediate impact.
