Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM.

And that's it! Do `npm run build` to create a production-ready version of your app, and check the project template's [README](https://github.com/sveltejs/template/blob/master/README.md) for instructions on how to easily deploy your app to the web with [Now](https://zeit.co/now) or [Surge](http://surge.sh/).
You're not restricted to using Rollup — there are also integrations for [webpack](https://github.com/sveltejs/svelte-loader), [Browserify](https://github.com/tehshrike/sveltify) and others, or you can use the [Svelte CLI](https://github.com/sveltejs/svelte-cli) (Update from 2019: with Svelte 3 the CLI was deprecated and we now use [sirv-cli](https://www.npmjs.com/package/sirv-cli) in our template. Feel free to use whatever tool you like!) or the [API](https://github.com/sveltejs/svelte/tree/v2#api) directly. If you make a project template using one of these tools, please share it with the [Svelte Discord chatroom](https://discord.gg/yy75DKs), or via [@sveltejs](https://twitter.com/sveltejs) on Twitter!

Speaking of Glimmer, the idea of compiling components to bytecode is one that we'll probably steal in 2018. A framework like Sapper could conceivably determine which compilation mode to use based on the characteristics of your app. It could even serve JavaScript for the initial route for the fastest possible startup time, then lazily serve a bytecode interpreter for subsequent routes, resulting in the optimal combination of startup size and total app size.
Mostly, though, we want the direction of Sapper to be determined by its users.

Unless you hang out in our [Discord server](https://discord.gg/yy75DKs) or follow [@sveltejs](https://twitter.com/sveltejs) on Twitter, you might not know that Svelte 3 is just around the corner, and it's going to be a huge release.

As grueling as this release has been, we're nowhere near finished. We have a ton of ideas for generating smarter, more compact code, and a long feature wish-list. [Sapper](https://sapper.svelte.dev), our Next.js-style app framework, is still in the middle of being updated to use Svelte 3. The [Svelte Native](https://svelte-native.technology/) community project, which allows you to write Android and iOS apps in Svelte, is making solid progress but deserves more complete support from core. We don't yet have the bounty of editor extensions, syntax highlighters, component kits, devtools and so on that other frameworks have, and we should fix that. We *really* want to add first-class TypeScript support.
But in the meantime we think Svelte 3 is the best way to build web apps yet. Take an hour to go through the [tutorial](tutorial) and we hope to convince you of the same. Either way, we'd love to see you in our [Discord chatroom](https://discord.gg/yy75DKs) and on [GitHub](https://github.com/sveltejs/svelte) — everyone is welcome, especially you.
