sapper

The next small thing in web development, powered by Svelte.

What is Sapper?

Sapper is a framework for building high-performance universal web apps. Read the guide or the introductory blog post to learn more.

SvelteKit

Sapper's successor, SvelteKit, is currently available for use. Please see the FAQ for more details.

Get started

Clone the starter project template with degit... When cloning you have to choose between rollup or webpack:

1npx degit "sveltejs/sapper-template#rollup" my-app
2# or: npx degit "sveltejs/sapper-template#webpack" my-app

...then install dependencies and start the dev server...

1cd my-app
2npm install
3npm run dev

...and navigate to localhost:3000. To build and run in production mode:

1npm run build
2npm start

Development

Pull requests are encouraged and always welcome. Pick an issue and help us out!

To install and work on Sapper locally:

1git clone https://github.com/sveltejs/sapper.git
2cd sapper
3npm install
4npm run dev

Linking to a Live Project

You can make changes locally to Sapper and test it against a local Sapper project. For a quick project that takes almost no setup, use the default sapper-template project. Instruction on setup are found in that project repository.

To link Sapper to your project, from the root of your local Sapper git checkout:

1cd sapper
2npm link

Then, to link from sapper-template (or any other given project):

1cd sapper-template
2npm link sapper

You should be good to test changes locally.

Running Tests

1npm run test
