This tutorial is designed to get you familiar with the process of writing components. But at some point, you'll want to start writing components in the comfort of your own text editor.

First, you'll need to integrate Svelte with a build tool. We recommend using SvelteKit, which sets up Vite with vite-plugin-svelte for you...

npm create svelte@latest myapp

There are also a number of community-maintained integrations.

Don't worry if you're relatively new to web development and haven't used these tools before. We've prepared a simple step-by-step guide, Svelte for new developers, which walks you through the process.

You'll also want to configure your text editor. There are plugins for many popular editors as well as an official VS Code extension.

Then, once you've got your project set up, using Svelte components is easy. The compiler turns each component into a regular JavaScript class — just import it and instantiate with new:

import App from './App.svelte';
const app = new App({
target: document.body,
props: {
// we'll learn about props later
answer: 42

You can then interact with app using the component API if you need to.
