How to Convert Crypto Currencies With GRPC Microservices in Node.js

Let’s face it: technical debt is inevitable and rewriting your code every 6 months is not an option. Refactoring is a complex topic that doesn't have a one-size-fits-all solution. Frontend applications are particularly sensitive because of frequent requirements and user flows changes. New abstractions, updated patterns and cleaning up those old functions - it all sounds great on paper, but it often fails in practice: todos accumulate, tickets end up rotting in the backlog and legacy code crops up in every corner of your codebase. So a process of continuous refactoring is the only weapon you have against tech debt.In the past three years, I’ve been exploring different strategies and processes for refactoring code. In this talk I will describe the key components of a framework for tackling refactoring and I will share some of the learnings accumulated along the way. Hopefully, this will help you in your quest of improving the code quality of your codebases.

As developers, we spend much of our time debugging apps - often code we didn't even write. Sadly, few developers have ever been taught how to approach debugging - it's something most of us learn through painful experience.  The good news is you _can_ learn how to debug effectively, and there's several key techniques and tools you can use for debugging JS and React apps.

Do you know what’s really going on in your node_modules folder? Software supply chain attacks have exploded over the past 12 months and they’re only accelerating in 2022 and beyond. We’ll dive into examples of recent supply chain attacks and what concrete steps you can take to protect your team from this emerging threat.

Many companies worldwide are considering adopting Micro-Frontends to improve business agility and scale, however, there are many unknowns when it comes to what the migration path looks like in practice. In this talk, I will discuss the steps required to successfully migrate a monolithic React Application into a more modular decoupled frontend architecture.

Next.js and other wrapping React frameworks provide great power in building larger applications. But with great power comes great performance responsibility - and if you don’t pay attention, it’s easy to add multiple seconds of loading penalty on all of your pages. Eek! Let’s walk through a case study of how a few hours of performance debugging improved both load and parse times for the Centered app by several hundred percent each. We’ll learn not just why those performance problems happen, but how to diagnose and fix them. Hooray, performance! ⚡️
