Sharing components Micro Frontends

Sharing components like common buttons and input fields between microservices can be achieved through several strategies. Here are some effective approaches:
๐ญ. ๐๐ผ๐บ๐ฝ๐ผ๐ป๐ฒ๐ป๐ ๐๐ถ๐ฏ๐ฟ๐ฎ๐ฟ๐ถ๐ฒ๐
Create a shared component library that includes all the reusable components (e.g., buttons, input fields). This library can be published as a package to a package registry (e.g., npm) and then imported into each microservice.
. ๐๐ฉ๐๐ฅ๐จ:
ย 1. Create a separate repository for the component library.
ย 2. Develop and test the components.
ย 3. Publish the library to a package registry.
ย 4. Install the library in each microservice project.
.๐ผ๐๐ซ๐๐ฃ๐ฉ๐๐๐๐จ:
โ-โCentralized management of components.
โ-โEasy updates and versioning.
.๐๐ถ๐๐ฎ๐ฑ๐๐ฎ๐ป๐๐ฎ๐ด๐ฒ๐:
โ-โRequires proper version management.
โ-โAll microservices need to be updated to use the latest version.

Use a monorepo setup with tools like Nx or Lerna to manage multiple projects in a single repository. This approach allows you to share code and dependencies easily between microservices.
. ๐๐ฉ๐๐ฅ๐จ:
ย 1. Set up a monorepo with Nx or Lerna.
ย 2. Create shared component libraries within the monorepo.
ย 3. Import and use the shared components in each microservice.
.๐ผ๐๐ซ๐๐ฃ๐ฉ๐๐๐๐จ:
โ-โSimplifies code sharing and dependency management.
โ-โEasier refactoring and consistency across microservices.
.๐๐ถ๐๐ฎ๐ฑ๐๐ฎ๐ป๐๐ฎ๐ด๐ฒ๐:
โ-โMonorepo can become complex to manage as it grows.
โ-โRequires a robust CI/CD pipeline.

Use Git submodules to include a shared repository (containing the common components) within each microservice repository.
. ๐๐ฉ๐๐ฅ๐จ:
ย 1. Create a repository for shared components.
ย 2. Add the shared repository as a submodule to each microservice repository.
ย 3. Use the shared components in the microservices.
.๐ผ๐๐ซ๐๐ฃ๐ฉ๐๐๐๐จ:
โ-โDirectly integrates with Git.
โ-โUpdates in the shared repository can be pulled into each microservice.
.๐๐ถ๐๐ฎ๐ฑ๐๐ฎ๐ป๐๐ฎ๐ด๐ฒ๐:
โ-โManaging submodule updates can be cumbersome.
โ-โNot as seamless as using a package registry.

In a micro-frontend architecture, each microservice can expose its components which can be used by other microservices through a shared component service or by importing them dynamically.
. ๐๐ฉ๐๐ฅ๐จ:
ย 1. Create a micro-frontend architecture where each microservice can publish its UI components.
ย 2. Use module federation (e.g., Webpack 5 Module Federation) to dynamically import components.
.๐ผ๐๐ซ๐๐ฃ๐ฉ๐๐๐๐จ:
โ-โPromotes independent deployment.
โ-โComponents can be updated independently.
.๐๐ถ๐๐ฎ๐ฑ๐๐ฎ๐ป๐๐ฎ๐ด๐ฒ๐:
โ-โRequires a more complex setup and configuration.
โ-โPotential for increased latency and load times.

Here's an example workflow using a component library published to npm:

Create reusable components like Button and Input in the library:

Install the library in each microservice:
Import and use the components in a microservice:
By following this approach, you can maintain a centralized library of reusable components and easily share them across your microservices, ensuring consistency and reducing duplication.
