@ManfredSteyer Monorepos
@ManfredSteyer Monorepo Structure
@ManfredSteyer Advantages Everyone uses the latest versions No version conflicts
No burden with distributing libs
@ManfredSteyer Two Flavors • Like Workspaces/Solutions in different IDEs Project
Monorepo • E. g. used at Google or Facebook Company-wide Monorepo
@ManfredSteyer Moving back and forth Npm Registry
@ManfredSteyer Tooling & Generator https://nrwl.io/nx
@ManfredSteyer Visualize Module Structure
@ManfredSteyer Further Selected Features of Nx • Restricting access b/w
apps and libs • Just recompile changed apps • Parallel compilation in the cloud • Integration of tooling: Cypress, Playwright, Storybook, …

@ManfredSteyer Idea const Component = import('other-app/xyz') Does not work with
webpack/ Angular CLI Even lazy parts must be known at compile time!
@ManfredSteyer Webpack 5 Module Federation 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 Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: {
} exposes: { Cmp: './my.cmp.ts' } loadRemoteModule({ type: 'module', remoteEntry: 'http://…', exposedModule: './Cmp' })
@ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend
(Remote) RemoteEntrypoint.js <script src="…"></script>
@ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared:
[ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]
@ManfredSteyer
@ManfredSteyer Default Behavior Selecting the highest compatible version ^10.0 ^10.1
@ManfredSteyer Default Behavior Conflict: No highest compatible version ^11.0 ^10.1
@ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true }
} 11.0 10.1
@ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true, strictVersion:
true // Error instead of warning! } } 11.0 10.1
@ManfredSteyer Relaxing Version Requirements shared: { "my-lib": { requiredVersion: ">=1.0.1
<11.1.1" } }
