create-svelte-app

This CLI provides you a way to create, build and serve your svelte app. Under the hood webpack is used for all operations.

npm i create-svelte-app -g

# yarn
yarn add global create-svelte-app

# or
yarn create svelte-app

How to use

Run all commands inside a svelte project. You don't need a bundler anymore, because as I said before, it already has a preconfigured webpack.

Example structure:

package.json
src/
  - App.svelte
  main.js

If you do not want this behavior, you can simple run svelte create and choose a template.

Single .svelte file

You can serve a .svelte file by runningsvelte FILE_PATH.svelte or svelte serve FILE_PATH.svelte. When you use this feature, a main.js is temporarily created by the CLI. If you want to pass props from this main file to your svelte file, you can set a JSON-String via the --props flag.

# or svelte serve ...
svelte ./test.svelte --props '{"prop":"hi there!"}'

And if you want to build a project with this .svelte file, run:

svelte build ./build.svelte --props '{"prop":"hi there!"}'

Custom Elements

This CLI makes it easy for you to create a custom element. Just run:

svelte build FILE_PATH.svelte --custom-element # or short -ce

The CLI creates the javascript file, and you can use your custom tag that you specified within your <svelte:options tag="your-custom-element"/> tag.
