The easiest way to get started with Svelte
This'll only take a minute.
Svelte is a new kind of framework. Rather than putting a
<script src='svelte.js'> tag on the page, or bringing it into your app with
Because of that, getting started with it can be a little bit confusing at first. How, you might reasonably ask, do you make a Svelte app?
1. Use the REPL
The Svelte REPL (Read-Eval-Print Loop) is the easiest way to begin. This is an interactive environment that allows you to modify code and instantly see the result.
At some point, your app will outgrow the REPL. Click the download button to save a
svelte-app.zip file to your computer and uncompress it.
Open a terminal window and set the project up...
cd /path/to/svelte-app npm install
...then start up a development server:
npm run dev
2. Use degit
In the terminal, you can instantly create a new project like so:
npx degit sveltejs/template my-svelte-project cd my-svelte-project # to use TypeScript run: # node scripts/setupTypeScript.js npm install npm run dev
This will create a new project in the
my-svelte-project directory, install its dependencies, and start a server on http://localhost:8080.
You can find more information about using TypeScript here.
Once you've tinkered a bit and understood how everything fits together, you can fork sveltejs/template and start doing this instead:
npx degit your-name/template my-new-project
And that's it! Do
npm run build to create a production-ready version of your app, and check the project template's README for instructions on how to easily deploy your app to the web with Vercel or Surge.
You're not restricted to using Rollup — there are also integrations for webpack, Browserify and others, or you can use the Svelte CLI (Update from 2019: with Svelte 3 the CLI was deprecated and we now use sirv-cli in our template. Feel free to use whatever tool you like!) or the API directly. If you make a project template using one of these tools, please share it with the Svelte Discord chatroom, or via @sveltejs on Twitter!
