Labą dieną Smashing Friends,

Legacy isn’t the most exciting matter in front-end or UX. We often speak about shiny new things, yet most products around run on legacy systems. These systems are slow, bulky, broken and unmaintained — but often business-critical, with a huge ecosystem of legacy dependencies on their own.

In this newsletter, we look into legacy — how to rebuild, refactor, redesign and migrate, both for front-end engineers and for UX designers. If you are working with legacy systems, hopefully you’ll find a few useful gems in there.

Meets: the Future of Design Systems
Smashing Meets Future of Design Systems, on Tuesday, Feb 27.

In the Smashing universe, we’ve just announced a few new (and free) community events — on The Future of Design Systems with Brad Frost and The Magic of CSS with Kevin Powell. We’d be absolutely delighted to see you there.

And as always, here’s a little reminder about a few thingies we’ve been tirelessly working for 2024:

Have a productive week, everyone — and hopefully you won’t have to struggle with legacy too much!

1. Understanding Legacy Code

We all have to deal with legacy code, and let’s be honest, it’s hard. To help you tame messy codebases without breaking anything, Nicolas Carlo started “Understand Legacy Code,” a collection of articles, guides, books, podcasts, and talks for refactoring code you’re afraid to change.

Understand Legacy Code

Whether you’re about to dive into a large, undocumented codebase, aren’t sure if a pattern will make the code more maintainable, or you feel you’ve hit the point of no return where burning it all and starting all over seems like the best option, Nicolas has got your back.

His guide also dives deeper into questions like what you can do to make others care about the technical debt that is piling up and how AI could help tame legacy codebases. One for the bookmarks. (cm)


2. Legacy System Modernization

Legacy systems are everywhere, and even though their technology is outdated, they power critical day-to-day operations. Think of the pager still in use in healthcare today, for example, or federal organizations relying on old software. And while changing a legacy system also brings along risks, the effort is well worth it.

Legacy System Modernization

A great starting point for tackling legacy systems and transforming an enterprise for a digital future is the whitepaper that AltexSoft published. It dives deep into legacy system modernization, the challenges it brings along, and best practices for solving them.

Another comprehensive guide to a UX-based overhaul of legacy building products comes from UX design agency Koru. It helps you understand the business value of your legacy application and explores three different approaches to making it more efficient, scalable, and safer. (cm)

3. Improving A Legacy Codebase

Probably every developer has been there before: You’re confronted with a legacy codebase and need to turn it into a healthy, maintainable project that doesn’t hinder your work. Where do you begin? Jacques Mattheij shares a roadmap that takes you through the complete process step by step — from making a backup to releasing your changes into production.

Five steps for managing legacy code

Jack Franklin also wrote a practical five-step guide to tackling legacy code. It helps teams prioritize updates and follow an incremental approach instead of a “big bang” release. A great reminder that legacy code is not a failing of an individual or a team and that we should learn to embrace it as an interesting technical challenge.

You want to dig even deeper into improving legacy codebases? Then Michael C. Feathers’ book Working Effectively with Legacy Code and Martin Fowler’s Refactoring: Improving the Design of Existing Code might be for you. (cm)


4. Upcoming Workshops and Conferences

That’s right! We run online workshops on frontend and design, be it accessibility, performance, or design patterns. In fact, we have a couple of workshops coming up soon, and we thought that, you know, you might want to join in as well.

Smashing Online Events
With online workshops, we aim to give you the same experience and access to experts as in an in-person workshop from wherever you are.

As always, here’s a quick overview:


5. UX Migration Strategy For Legacy Applications

Planning ahead and putting users first is key to successfully migrating a legacy application. To help you master the challenge, Tamara Chehayeb Makarem shares her UX migration strategy for legacy applications. It goes beyond simply moving existing features to a new system and instead helps you build a strategic system that supports your business goals.

UX Migration Strategy for Legacy Applications

Tamara’s strategy consists of three steps. In the first step, you’ll identify the reasons for the migration and its impact on users. The second step involves choosing the best migration option for your context. Finally, the third step is all about outlining your goals and planning your strategic roadmap. A handy set of guidelines to help you ensure your new system is adopted and welcomed by users. (cm)

6. Designing With Legacy

Having faced legacy in all major career assignments, Peter Zalman knows from experience that there is no single correct approach to dealing with decades-old product legacy. But a few common patterns can help teams make the right decisions, as he points out in his article “Designing With Legacy.”

Designing With Legacy

In the article, Peter highlights the risks that a complete redesign and continuous improvements can bring along, putting special focus on an aspect that can easily be overseen: the users’ emotional attachment to the existing product. The article is also a great reminder that you’re not only dealing with a legacy product but also with a knowledge base that has grown over years and that can’t just be replaced with a shiny new design concept. A must-read to prevent you from hasty decisions that could do more harm than good. (cm)
