33. @ManfredSteyer If you use webpack: No need to hurry. Stick with webpack Module Federation
34. @ManfredSteyer If you use esbuild or vite: Give Native Federation a try and provide feedback
35. @ManfredSteyer Once, Angular CLI supports esbuild: Give Native Federation a try and provide feedback
36. @ManfredSteyer In general: Native Federation is your insurance for the mid- and long-term
37. @ManfredSteyer • How to implement maintainable architectures with Monorepos, Standalone Components, DDD, and NX? • How to implement Micro Frontends w/ Module Federation, Standalone Components and Web Components ? • … Public or Company Training, Remote or On-Site German and English
38. @ManfredSteyer Module Federation: Mental Model rocks! Import Maps: Provide low level building blocks Native Federation: Insurance Try out with esbuild, vite, etc.
