Everything you need to build a Svelte project, powered by
create-svelte.
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npm create svelte@latest
# create a new project in my-app
npm create svelte@latest my-appOnce you've created a project and installed dependencies with npm install (or
pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --openTo create a production version of your app:
npm run buildYou can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
