Before you decide if Micro frontend is the right solution, it is good to see both sides, the good and the hard.
Let me point it out based on my experience.
Pros
Teams can work on different modules and deploy it separately
We can test modules in full isolation
MFE lead you to structure your application and its modules in the best way for distributed teams
MFE becoming the saviour if you want to support different themes across many apps
Cons or disadvantages of micro frontends
Application becomes more complex
You must review your common dependencies and avoid using different versions in parent-in-child apps
Responsibility for Micro Frontend modules is not clear between teams
E2E testing is challenging task
MFE deployments can't work without knowing your MFEs domains in advance.
Routing requires more attention, especially if you are using SSR
If you think that Micro frontend architecture is still worth it, you should learn how to plan it correctly. This article about MFE architecture might help you to do it.

FAQs
Does the micro frontend architecture have cons?
Yes, as with any architecture, it has things that you need to consider as downsides.
What are the main pros of using micro frontend architecture?
The main advantage is that teams can work on different parts of your app and deploy it separately.
What are Micro Frontends?
Micro Frontends is an architectural style for building user interfaces that involves decomposing the front-end of a web application into individual, loosely-coupled microservices.
What are the benefits of using Micro Frontends?
Some of the benefits of using Micro Frontends include independent development and deployment, reusability, scalability, and faster development.
What are the drawbacks of using Micro Frontends?
Some of the drawbacks of using Micro Frontends include increased complexity, testing challenges, performance issues, and potential security vulnerabilities.
How does Micro Frontends differ from Microservices?
Microservices are typically focused on the back-end of an application, while Micro Frontends are focused on the front-end.
What technologies are used in Micro Frontends?
Micro Frontends can be implemented using a wide range of technologies, including React, Angular, Vue.js, and more.
How does Micro Frontends impact team collaboration?
Micro Frontends can enable teams to work independently on different parts of the application, which can improve collaboration and increase productivity.
Is Micro Frontends suitable for all types of applications?
Micro Frontends may not be suitable for all types of applications, as it depends on the specific needs and requirements of the application.
How can I ensure the security of my Micro Frontends?
It is important to carefully evaluate the security risks associated with Micro Frontends and ensure that all microservices are secure and up-to-date.
How does Micro Frontends impact page load times?
Micro Frontends can have an impact on page load times, as there can be a lot of network communication between microservices.
Is it difficult to adopt Micro Frontends?
Adopting Micro Frontends can be challenging, as it requires a shift in mindset and may require changes to existing development processes. However, with proper planning and implementation, it can be a valuable approach for building scalable and maintainable user interfaces.
What is micro frontend architecture?
Micro frontend architecture is an approach to web application development that breaks down front-end applications into smaller, independent parts called micro frontends. Each micro frontend is developed and maintained by a different team or individual, and the overall web app is composed of multiple, self-contained micro frontends.
What are the advantages of using micro frontends?
Micro frontends allow multiple teams to work on different parts of a web application independently, without worrying about conflicting code changes or dependencies. This approach also makes it easier to adopt microservices architecture, as each micro frontend can communicate with its own microservice.
Are there any drawbacks to using micro frontends?
One potential drawback is increased complexity, as a micro frontend approach may require more communication and coordination between teams. Additionally, micro frontends may not be the best solution for all web development scenarios, and it is important to consider the specific needs of your project before adopting this approach.
How can a developer implement a micro frontend architecture?
Developers can implement a micro frontend architecture by breaking down their front-end applications into smaller, self-contained parts. This involves establishing clear boundaries between different parts of the application, and creating custom elements or web components that can be shared across multiple micro frontends.
What are some best practices for implementing micro frontends?
Some best practices for implementing micro frontends include using a component library to share resources across different micro frontends, maintaining a clear separation of concerns between different parts of the application, and ensuring that each micro frontend is independently deployable and testable.
Can a micro frontend architecture be used with multiple teams?
Yes, a micro frontend architecture is designed to accommodate multiple teams working on different parts of a web application. Each team can develop and maintain their own micro frontend, and these micro frontends can communicate with each other through APIs or other communication channels.
Can a micro frontend approach be used with monolithic applications?
Yes, a micro frontend approach can be used with monolithic applications. In fact, it can be a useful way to break down a large, monolithic application into smaller, more manageable parts that can be developed and maintained independently.
What is the role of APIs in a micro frontend architecture?
APIs are a critical component of a micro frontend architecture, as they allow different micro frontends to communicate with each other and with backend services. APIs can be used to share data, coordinate actions, and ensure consistency across different parts of the application.
How can a micro frontend approach improve user experience?
A micro frontend approach can improve user experience by allowing developers to focus on specific parts of the application, rather than trying to manage the entire application as a monolith. This can result in faster development cycles, better code quality, and ultimately, a more user-friendly web app.
Can a micro frontend architecture be used with any front-end framework or language?
Yes, a micro frontend architecture can be used with any front-end framework or language, including JavaScript, React, Angular, Vue, and more. The key is to establish clear boundaries between different parts of the application, and to create independent micro frontends that can communicate with each other and with backend services as needed.
