@ManfredSteyer µService µFrontend µFrontend µFrontend Shell
@ManfredSteyer iframe Bootstrapping several SPAs Module Federation + meta frameworks
using these approaches e. g. SAP Luigi Framework
@ManfredSteyer <other-spa></other-spa> <script src="other-spa/bundle.js"></script>
@ManfredSteyer const script = document.createElement('script'); script.src = 'other-spa/bundle.js'; document.body.appendChild(script); const
myElement = document.createElement('other-spa'); myElement['visible'] = true; document.body.appendChild(myElement);
@ManfredSteyer Option: Wrap them into Web Components Angular App (MFE)
React App (MFE)
@ManfredSteyer const Component = import('http://other-app/xyz')
@ManfredSteyer Shell (Host) Microfrontend (Remote) // Maps Urls in //
webpack config remotes: { mfe1: "http://..." } // Expose files in // webpack config exposes: { Cmp: './my.cmp.ts' } import('mfe1/Cmp')
@ManfredSteyer Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ]
shared: [ "@angular/core", "…" ]
@ManfredSteyer Single Framework/ Version Multiple Frameworks/ Versions Like Lazy Loading
Like bootstrapping several SPAs + Sharing where same version No workarounds Some workarounds
