READ THIS FIRST!

SvelteKit is still in beta. Expect bugs! Read more here, and track progress towards 1.0 here.

Documentation

Please see the documentation for information about getting started and developing with SvelteKit.

Developing

This monorepo uses pnpm. Install it...

npm i -g pnpm

...then install this repo's dependencies...

pnpm i

...then build SvelteKit and the other packages:

pnpm build

You should now be able to run the examples by navigating to one of the directories and doing pnpm dev.

Run pnpm dev inside the packages/kit directory to continually rebuild @sveltejs/kit as you make changes to SvelteKit. Restarting the example/test apps will cause the newly built version to be used.

To use the git hooks in the repo, which will save you waiting for CI to tell you that you forgot to lint, run this:

git config core.hookspath .githooks

Changelogs

For changes to be reflected in package changelogs, run pnpx changeset and follow the prompts. All changesets should be patch until SvelteKit 1.0

Releases

The Changesets GitHub action will create and update a PR that applies changesets and publishes new versions of changed packages to npm.

It uses pnpm publish rather than pnpx changeset publish so that we can use the --filter and (while in beta) --tag flags — though perhaps they work with pnpx changeset publish?

New packages will need to be published manually the first time if they are scoped to the @sveltejs organisation, by running this from the package directory:

npm publish --access=public

Testing

Run pnpm test to run the tests from all subpackages. Browser tests live in subdirectories of packages/kit/test such as packages/kit/test/apps/basics.

You can run the tests for only a single package by first moving to that directory. E.g. cd packages/kit.

You must rebuild each time before running the tests if you've made code changes.

To run a single integration test, provide the FILTER env var with the test name. E.g. FILTER="includes paths" pnpm test:integration. You can also open up the file and change test to test.only.

You can run the test server with cd packages/kit/test/apps/basics; pnpm run dev to hit it with your browser.
