Check create-svelte
Everything you need to build a Svelte project, powered by
create-svelte.
Creating a project
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-app
Developing
Once 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 -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
Create project benchmark
$ npm create svelte@latest benchmark
