The packages behind an editor-driven web app framework with server-side rendering, published for developers following its move to open source.
Nordcraft builds web apps with server-side rendering, branching, version control and components, and this repository holds the packages that make the framework run. It is also the vehicle for a plan announced in 2024 to open the whole product and make a Nordcraft application self-hostable.
Each package is published to npm and consumed internally by the framework. The repository is built with bun, which handles install, linting, type checking and a single build across every package at once.
The packages divide the runtime along clear lines.
- Core: shared logic that every other package depends on.
- Runtime: hydrating, running and updating an application in the browser.
- SSR: the server-side rendering logic, and the current focus of the migration.
- Standard library: the built-in formulas and actions used by the runtime and during rendering.
- Search: issue rules and project traversal, powering the editor's issue panel inside a web worker.
- CSS parser: the parser behind the style panel in the editor.
The maintainers are candid about the status. Packages are used internally but are not yet ready for outside applications to consume, and most current work lands in the rendering package. Releases go to GitHub and npm once a version bump is merged. Issues and pull requests are welcome, and the documentation lives in its own open repository.
