Node module caching

Immutable, exact-versioned module requests (the module CDN's /package/... endpoints and unpkg files) are cached at runtime in a persistent Cache API cache — see registerImmutableUrlPrefix in src/utils/fetch.ts. The first fetch of a given URL populates the cache; later loads are served from it without touching the network. There is nothing to regenerate or check in.

Sandpack Bundler

The sandpack bundler, this aims to eventually replace the current sandpack with a more streamlined and faster version.

Getting started

1. Run yarn to install dependencies.
2. Run yarn dev to start the development server
3. Set the bundlerURL of sandpack-react to http://localhost:1234/ to see it in action.

Test the production build (performance/integration tests)

1. Run yarn to install dependencies.
2. Run yarn build to build the application
3. Run yarn start to start a local test server
4. Set the bundlerURL of sandpack-react to http://localhost:4587/

Using the deployed version

The main branch of this repository is automatically deployed to https://sandpack-bundler.codesandbox.io so you can update bundlerURL of sandpack-react to that url and start using the new sandpack bundler.
