Your First App

This guide walks you through creating a new Korporus app from scratch.

1. Create the Package

Create a new directory in packages/:

packages/my-app/
  package.json
  tsconfig.json
  vite.config.ts
  index.html
  app-manifest.json
  icon.svg
  src/
    bootstrap.ts
    main.tsx
    store.ts
    components/
      MyMenubar.tsx
      MyMain.tsx

2. Configure Module Federation

In vite.config.ts, set up the MF remote:

federation({
  name: "my_app",
  filename: "remoteEntry.js",
  manifest: true,
  exposes: {
    "./bootstrap": "./src/bootstrap.ts",
  },
  shared: {
    react: { singleton: true, requiredVersion: "^19.0.0" },
    "react-dom": { singleton: true, requiredVersion: "^19.0.0" },
    zustand: { singleton: true },
  },
  dts: false,
})

3. Register Web Components

In bootstrap.ts, register your app slot components:

import { registerCustomElement } from "@korporus/web-component-wrapper";

registerCustomElement("my-app-menubar", MyMenubar);
registerCustomElement("my-app-main", MyMain);

4. Register with the Shell

Add a manifest JSON to apps/shell/public/manifests/my-app.json and add it to the MANIFEST_URLS array in apps/shell/src/config/apps.ts.

See the App Manifest Schema for the full manifest format.
