Implements the runtime environment for Open Pioneer Trails apps. Additionally, the package provides some services that provide useful functionalities for app development.
Import the createCustomElement function from this package to create your application as a Web Component:
// my-app/app.js
import { createCustomElement } from "@open-pioneer/runtime";
import * as appMetadata from "open-pioneer:app";
import { AppUI } from "./AppUI";
const Element = createCustomElement({
component: AppUI,
appMetadata
});
customElements.define("my-app", Element);
In this example, Element is a custom web component class registered as <my-app>.
The application renders the AppUI (a React component) and automatically contains services, styles etc. its package dependencies.
HTML sites or JavaScript code can now instantiate the application by creating a DOM-Element:
<!-- some-site/index.html -->
<!doctype html>
<html>
<body>
<!-- Contains the app once the script has been loaded -->
<my-app></my-app>
<script type="module" src="/apps/my-app/app.ts"></script>
</body>
</html>
If a hard error occurs on application start, the AppUI cannot be rendered but an error screen is shown instead.
The error screen shows a message to the user that an error occurred on application start.
The error screen is available in english (fallback) and german.
If the application was started in DEV-mode, the error screen shows additional information about the error and the stack trace.
The package contains services that provide different functionalities useful for app development. For details, see the API description of the respective service.
The ApplicationContext provides access to global application values. E.g. the web component's host element and the current locale.
The NumberParserService provides a method to parse a string to a number according to the current locale.
