Overcoming the Implementation Challenges of Micro-Frontends

A comprehensive guide of the micro-frontend architecture and implementation challenges.

Prompted and edited by the author.

Micro-frontends represent a paradigm shift in how we think about building web applications, offering a path to truly decoupled, domain-aligned UI components. Despite their potential for enhancing scalability and flexibility, implementing micro-frontends comes with its set of challenges. In this article, I will present the key concepts, why they are relevant, and how they can be dealt with to have a successful micro-frontend architecture.

Before discussing how micro-frontends work and the patterns we can apply, it’s important to first talk about two things: Domain-Driven Design and microservices. We’ll only briefly introduce the former, as it’s necessary to understand where this methodology fits. The latter, microservices, will be explored to comprehend the needs of a ‘micro’ architecture, and since these needs are already addressed in microservices, it will help us better understand what we need to do at the micro-frontend level.

Domain-Driven Design

The Domain-Driven Design (DDD) is a software construction methodology that is divided into two fundamental parts: strategy and tactics. Tactics are what everyone…

Loved this! We have a newsletter with similar content on Microservices, Backend, Distributed Systems and more, check it out if you're interested: https://packagemain.tech

Very good article.
To emphasise the point, comms between MFEs should not be via function interfaces as this breaks the major tenet of independence.
In fact the relationship between MFEs is best expressed as "corporative" rather than "dependent" i.e…

The micro-frontend architecture has very similar needs to those of a microservice

Agreed. So similar, in fact, that I struggle to understand the need to replicate persistence, query support, command mechanisms, and event pub/sub.
Why not use the same, already-existing mechanisms with microservices modeling front entities like session, state, control, etc?
