v0.3.0 Release Notes¶

Release Date: 2026-10-15

Adds @plexusone/host at 0.3.0. The other packages are unchanged.

Highlights¶

Applications export their pages once. An application exports an AppModule, its routes and what it adds to the chrome, and reads where it runs from useAppContext(). It never imports a shell.
Stacks bring their own chrome. createHost({ app, shell }) provides the session, the router under /orgs/:org, organization selection, and not-found and no-access pages, with the stack's Shell around the application. Swapping the shell changes only the chrome.
Run an application on its own. DevShell is a neutral shell, and devSession runs the application's interface with no backend: createHost({ app, devSession: true }).
Test it as it is hosted. renderApp from @plexusone/host/testing renders the application in a memory router with a fixture session and any shell; conformanceProblems names what keeps a module from being hostable.

@plexusone/shell and @plexusone/auth 0.2.1 or later.
React 19, and react-router 7 or 8. React Router 8 has no react-router-dom; @plexusone/host imports react-router, which an application on 7 also has.
@testing-library/react only for @plexusone/host/testing.
