Community add-ons

Community add-ons are currently experimental. The API may change. Don't use them in production yet!

Community add-ons are npm packages published by the community. Look out for add-ons from your favorite libraries and tools. (soon) many are building sv add-ons to make integration a one-liner. You can find them on npm by searching for keyword: sv-add.

# Install a community add-on by org
npx sv add @supacool

# Use a local add-on (for development or custom/private add-ons)
npx sv add file:../path/to/my-addon

# Mix and match official and community add-ons
npx sv add eslint @supacool

# Also works when creating a new project directly
npx sv create --add eslint @supacool
