10. @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')
11. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]
12. @ManfredSteyer 1) ng add @angular-architects/module-federation 2) Adjust generated configuration 3) ng serve
