Micro-frontends are the architectural equivalent of microservices for the web. They allow massive teams to work on the same product without stepping on each other's toes.
Why use Micro-Frontends?
- Independent Deployments: Deploy the checkout module without touching the search or profile modules.
- Technology Agnostic: Use React for the dashboard and Vue for the blog if needed (though not always recommended).
- Reduced Build Times: Only build and test the parts of the app that changed.
Implementation Strategies:
- Module Federation: The standard for sharing code between apps at runtime.
- Web Components: For truly framework-agnostic modularity.
- Edge Side Includes (ESI): Stating components at the CDN level.
Micro-frontends solve the organizational bottleneck of scaling a frontend team.
