When React state management is not enough, I use atoms

I'm a fan of Kent C. Dodds. He has an excellent blog, he holds office hours on Youtube and he manages an active Discord community focused on helping developers make maintainable React apps. I especially appreciate the way he thinks about state management in React apps. It does not have to be so reliant on external libraries. React itself is a library for managing state, so why not depend on its built-in abstractions.

On a React Native app I'm building, most (> 95%) of the state management is indeed done with the React primitives: useStates, Contexts, and Refs. It is a big pile of hook compositions, and that's the way I like it. If you are familiar with React and can read its documentation, you can understand the code.

There are a handful of places where using the primitives fall short, though. In these spots, plain old React hooks would require excessive glue code and would ultimately be confusing. Also, skipping needless renders in components such as forms can be tricky with the tools out of the box.

The savior is a shared state with an atom using Jotai! It has a simple useState-like API familiar to a React developer. It does not need stores, providers, or excessive boilerplate. Even the unit tests don't need anything special. I'll not detail how Jotai helps us, but it is a terrific tool to use sparingly.

Jotai was actually the second iteration of atomic state management: we initially used Recoil (0.1.X), but we decided to ditch that. It had some bugs, the most significant of which was a flaw where the selectors would trigger extra renders and not work as a selector should. This was more than six months ago, so I'm sure most of the issues are fixed.

Complying with Kent C. Dodds and plenty of other seasoned React developers, I'll design my React application around the React state management hooks and stick to them as much as possible. When the need arises to introduce something more sophisticated, I use a simple abstraction such as atoms. If the complexity with this abstraction is still too high compared to the added complexity introduced by something like Redux, MST, or Xstate, only then I'll start using them. I'll never start a React project by immediately tightly coupling it to another state management library.

I'm not a passionate developer

A family friend of mine is an airlane pilot. A dream job for most, right? As a child, I certainly thought so. Now that I can have grown-up talks with him, I have discovered a more accurate description of his profession. He says that the truth about the job is that it is boring. To me, that is not that surprising. Airplanes are cool and all, but when you are in the middle of the Atlantic sitting next to the colleague you have been talking to past five years, how stimulating can that be? When he says the job is boring, it is not a bad kind of boring. It is a very specific boring. The "boring" you would want as a passenger. Uneventful. Yet, he loves his job. According to him, an experienced pilot is most pleased when each and every tiny thing in the flight plan - goes according to plan. Passengers in the cabin of an expert pilot sit in the comfort of not even noticing who is flying. As someone employed in a field where being boring is not exactly in high demand, this sounds pro...

Canyon Precede:ON 7

I bought or technically leased a Canyon Precede:ON 7 (2022) electric bike last fall. This post is about my experiences with it after riding for about 2000 km this winter. The season was a bit colder than usual, and we had more snow than in years, so I properly put the bike through its paces. I've been cycling for almost 20 years. I've never owned a car nor used public transport regularly. I pedal all distances below 30km in all seasons. Besides commuting, I've mountain biked and raced BMX, and I still actively ride my road bike during the spring and summer months. I've owned a handful of bikes and kept them until their frames failed. Buying new bikes or gear has not been a major part of my hobby, and frankly, I'm quite sceptical about the benefits of updating bikes or gear frequently. I've never owned an E-bike before, but I've rented one a couple of times. The bike arrived in a hilariously large box. I suppose there's no need to worry about damage durin...

Emit structured Postgres data change events with wal2json

A common thing I see in an enterprise system is that when an end-user does some action, say add a user, the underlying web of subsystems adds the user to multiple databases in separate transactions. Each of these transactions may happen in varying order and, even worse, can fail, leaving the system in an inconsistent state. A better way could be to write the user data to some main database and then other subsystems like search indexes, pull/push the data to other interested parties, thus eliminating the need for multiple end-user originating boundary transactions. That's the theory part; how about a technical solution. The idea of this post came from the koodia pinnan alla podcast about event-driven systems and CDC . One of the discussion topics in the show is emitting events from Postgres transaction logs. I built an utterly simple change emitter and reader using Postgres with the wal2json transaction decoding plugin and a custom go event parser. I'll stick to the boring ...
