sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npx sv create
# create a new project in my-app
npx sv create 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.
Local SSL Development
This project uses HTTPS for local development. The certificates are generated using a local Caddy instance.
To trust the local CA and avoid browser warnings:
-
Linux (Ubuntu/Debian):
sudo cp .ssl/root.crt /usr/local/share/ca-certificates/caddy-local.crt sudo update-ca-certificates -
Chrome/Chromium: You might need to import the authority in Chrome settings:
- Go to
chrome://settings/certificates - Click "Authorities" -> "Import"
- Select
.ssl/root.crt - Check "Trust this certificate for identifying websites"
- Go to
