Original: Composing micro-frontends with import maps and native ES modules
Short summary
The article introduces Runtime Module Composition (rmc-toolkit), a micro-frontend architecture built on browser-native ES modules and import maps rather than custom bundlers or module loaders. A single manifest object generates the import map, configures the build, and drives the router, eliminating hand-maintained integration layers. The approach trades build-time complexity for a small shared convention that preserves team autonomy while keeping the system understandable.
- •Import maps provide browser-native dependency resolution without bundlers or custom loaders
- •A single manifest object drives the import map, build config, and router simultaneously
- •rmc-toolkit eliminates the need for a custom module-loading runtime, reducing failure surface
