Example

Use the root render context to inject dependencies, expose a public API, and render registered components within one app:

import {
  createApp,
  createInjectionKey,
  dynamicComponent,
  html,
  inject,
  refreshGluonApplications,
  runWithErrorHandling,
  unmount,
  warn,
  type AppConfig,
  type AppContainer,
  type AppErrorHandler,
  type AppErrorInfo,
  type AppErrorSource,
  type AppMount,
  type AppPluginCleanup,
  type AppRoot,
  type AppRootRenderContext,
  type AppWarningHandler,
  type AppWarningInfo,
  type FunctionalComponent,
  type GluonApp,
  type GluonAppPlugin,
  type GluonPlugin,
  type GluonPluginFunction,
  type InjectionKey,
} from '@gluonjs/core';

type PublicApi = { refresh(): void };
const localeKey: InjectionKey<string> = createInjectionKey<string>('locale');
const ShopView: FunctionalComponent<{ locale: string }> = ({ locale }) => html`<main lang=${locale}>Shop</main>`;
const root: AppRoot<PublicApi> = (context: AppRootRenderContext<PublicApi>) => {
  const locale = inject(localeKey, context.inject(localeKey, 'en'));
  context.expose({ refresh: () => console.log('refresh') });
  return html`${dynamicComponent('ShopView', { locale })}`;
};
const errorHandler: AppErrorHandler = (info: AppErrorInfo) => console.error(info.source, info.error);
const warningHandler: AppWarningHandler = (info: AppWarningInfo) => console.warn(info.code, info.message);

const cleanup: AppPluginCleanup = () => console.log('logger disposed');

  .provide(localeKey, 'de')
  .component('ShopView', ShopView)
  .use(plugin)
  .use(typedPlugin, { prefix: '[shop]' });
const config: AppConfig = app.config;

const container: AppContainer = document.querySelector('#app')!;
const mount: AppMount<PublicApi> = app.mount(container);
