12. @ManfredSteyer Idea const Component = await import('http://other-app/xyz')
13. @ManfredSteyer Webpack 5 Module Federation Shell (Host) Microfrontend (Remote) // Maps Urls in // webpack config remotes: { mfe1: "mfe1" } // Expose files in // webpack config exposes: { './Cmp': './my.cmp.ts' } import('mfe1/Cmp')
14. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]

16. @ManfredSteyer Custom Elements class MyElement extends HTMLElement { connectedCallback() { this.innerHTML = '<b>Hello World!</b>' } }
17. @ManfredSteyer Custom Elements class MyElement extends HTMLElement { connectedCallback() { this.innerHTML = '<b>Hello World!</b>' } } customElements.define('my-element', MyElement);
18. @ManfredSteyer Custom Elements class MyElement extends HTMLElement { connectedCallback() { ReactDOM.render(<App/>, this); } } customElements.define('my-element', MyElement);
19. @ManfredSteyer Loading Web Components <script src="bundle.js"></script> […] <my-element></my-element>
20. @ManfredSteyer Simple Script Loader const script = document.createElement('script'); script.src = 'assets/bundle.js'; document.body.appendChild(script);
21. @ManfredSteyer Dynamically Adding a Web Component const script = document.createElement('script'); script.src = 'assets/bundle.js'; document.body.appendChild(script); const myElement = document.createElement('myElement'); myElement['visible'] = true; document.body.appendChild(myElement);
