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

#webdev #svelte #sveltekit #opensource

Sometimes you just need a simple tool to do one thing well. That's the philosophy behind Svelte-MiniApps.

This kind of project is also a great way to stay sharp: small apps force you to finish things, polish edges, and learn the framework in a “real” environment.

What is Svelte-MiniApps?

Svelte-MiniApps is an open-source project containing a collection of small, single-purpose applications. Originally started as an experiment with SvelteKit, it has evolved into a robust set of utilities, now fully updated for Svelte 5 in 2025.

It’s important to clarify the shape of the project: this is one repository and one website that contains all the mini apps. You don’t install each tool separately — you just run the app, and navigate to the mini tool you need.

Each mini-app is designed to tackle a specific task, offering a clean, user-friendly experience without the bloat of larger, multi-purpose suites.

What's Inside?

The collection includes various tools that might come in handy for developers and casual users alike. (Note: You can check the repo for the latest list, but typical examples includes calculators, converters, or simple tracking tools).

What I like about this format is that each mini-app can be:

iterated independently (separate pages/routes, small surface area) while still being deployed as one lightweight site
understood quickly (easy onboarding for contributors)
refactored safely (small blast radius)

And because Svelte is compile-time focused and the apps are intentionally small, the overall site can stay fast and resource-friendly as the collection grows — especially if you keep dependencies lean and avoid shipping heavyweight UI where it’s not needed.

The project serves two main purposes:

Utility: Providing useful tools for everyday tasks.
Education: Serving as a reference for modern Svelte 5 development. You can explore the code to see how to structure Svelte 5 applications, use the latest runes system, and handle state effectively.

If you're learning Svelte 5, this is the kind of repo that's more useful than toy examples, because it shows the boring-but-important stuff: folder layout, state patterns, UI composition, and keeping things readable.

2025 Updates

As of 2025, the project has been actively maintained and updated to leverage the latest features of the Svelte ecosystem. If you are looking for examples of real-world Svelte 5 code, this repository is a great place to start.

How to use it

Browse the repo and pick a mini-app that matches what you're trying to learn.
Read it end-to-end (they’re intentionally small), then tweak one behavior and see how the change flows through.
Steal the patterns you like for your next project.

Contributing

Svelte-MiniApps is open source! If you have an idea for a mini-app or want to improve an existing one, contributions are welcome. It's a great way to practice your Svelte skills and give back to the community.
