Even a small bug in checkout or payments can lead to abandoned carts, lost trust, and thousands in missed sales. As your store scales, the stakes get higher. In this guide, we'll cover how to test your Medusa store effectively - from unit and integration tests to full end-to-end, performance, and security testing. You'll learn the tools, best practices, and strategies that help Medusa-based stores handle real-world traffic, avoid regressions, and scale with confidence. Catching Regressions Early: A single breaking change in your checkout flow can cost thousands in lost sales before you even notice. Automated tests catch these issues during development, not in production. Proving Requirements Are Met: Whether it's ensuring your platform can handle Black Friday…...

6+ min ago (1298+ words) I learned more about a developer from reading three months of their commit messages than I did from reviewing six months of their code. The code was competent'clean functions, reasonable abstractions, tests that passed. Standard mid-level work. But the commit messages told a completely different story. They revealed how this person thought through problems, made decisions under uncertainty, and communicated intent to future maintainers. One commit said: "fix: resolve race condition in payment processing by adding mutex lock to transaction handler." Another said: "fix bug." Your commit messages aren't just documentation. They're a running transcript of your engineering judgment. Most developers treat commit messages as bureaucratic overhead'something required by CI/CD but fundamentally pointless. Write enough to satisfy the linter, move on. The actual value is in the code. Your code shows what you built. Your commit messages show why…...

Now though, the shutdown has ended, and the OnePlus 15 is about to go up for pre-order. You'll be able to pre-order the phone from tomorrow (December 4) at 8am PT / 11am ET. The company hasn't said exactly when the OnePlus 15 will ship, but in a reply to the announcement on its X account, OnePlus claimed that "this drop is imminent." The phone starts at $899.99, for which you'll get a version with 256GB of storage and 12GB of RAM. Or, for $999.99, you can get one with 512GB of storage and 16GB of RAM. That's not cheap, but if you pre-order the OnePlus 15, you'll also get…...

14+ min ago (677+ words) Nvidia announced the latest in a string of AI-centric collabortions and investments. The company is pouring $2 billion into electronic design automation (EDA) specialist Synopsys. While Nvidia's involvement certainly ups the ante, it's important to take a step back and look at the big picture. Since the dawn of AI, Nvidia has given investors plenty to consider, investing billions of dollars into six AI-centric companies, as well as making sizable deals with several others. Just this week, the company announced another strategic investment, this time in Synopsys (NASDAQ: SNPS), one of the leaders in chip design. Let's take a look at Nvidia's latest move and whether investors should follow suit. In a joint press release that dropped on Monday, the pair announced a "multiyear collaboration" focused on expanding the reach of Nvidia's widely used Compute Unified Device Architecture (CUDA), a library…...

16+ min ago (505+ words) Introduction In the realm of modern web development, the synergy between frontend frameworks like React and cloud computing technologies such as Serverless Framework has opened up new possibilities for developers to create dynamic and scalable applications. Understanding React React, developed by Facebook, is a powerful JavaScript library for building user interfaces. Its component-based architecture and virtual DOM make it a popular choice for creating interactive web applications. Example React Component import React from 'react'; const App = () => { return ( Hello, World! ); }; export default App; Embracing Serverless Architecture Serverless Framework allows developers to focus on writing code without the need to manage servers. By leveraging cloud services like AWS Lambda, Azure Functions, or Google Cloud Functions, developers can deploy functions that automatically scale based on demand. Example Serverless Function module.exports.handler = async (event) => { const name = event.queryStringParameters.name || 'World'; return { statusCode: 200, body:…...

17+ min ago (273+ words) Let's be real for a second. Insurance apps are full of repetitive, predictable flows: Add a driver " Fill a form " Click Next " Review " Pay " Done. Do we really want to rebuild the same steps every single time? Guidewire took one look at that chaos and said: "Developers deserve better. And faster. And less repetitive stress." That's why Patterns exist in JDP (Jutro Digital Platform). If Jutro Components are the LEGO bricks, Patterns are the pre-built LEGO sets that already look like a car, a house, or a spaceship, you just customize the colors and stickers. Patterns are reusable, ready-to-go UI flows built from multiple Jutro components, designed specifically for insurance journeys. You don't have to reinvent multi-step forms, document upload flows, payment steps, quote summaries, or review pages. Patterns say: "Here's the structure, logic, layout, UX rules you handle the…...

21+ min ago (1551+ words) I spent two months building a feature that I deleted in a single afternoon. The code was clean. The tests passed. The architecture was solid. But the fundamental approach was wrong, and no amount of refactoring could save it. I had optimized for the wrong metric, built for the wrong use case, and designed around assumptions that reality brutally disproved. Two months of work. Gone. My first instinct was to bury it. Pretend it never happened. Move on to the next thing and hope nobody asked too many questions about that mysterious gap in my commit history. After all, why would I want to document my failure publicly? Then I wrote a post-mortem. Not for my team'for the internet. I published everything: what I built, why it failed, what I should have done differently, and the specific warning signs I…...

34+ min ago (594+ words) You know the feeling. You spend three hours on a Saturday night with Claude or Cursor. You're in the flow. You prompt, it generates, you paste. The app works. You show your non-technical friends who think you're a genius, and you feel like you've unlocked a superpower. Life is good. Then, the hangover hits. You notice a bug, or you want to add a "quick" feature. Or worse, you pushed to production, and now users are starting to notice issues. Suddenly, you're staring at thousands of lines of code you didn't really write and, let's be honest, don't really understand. You beg the AI to "fix it," but since it has no memory of why it made those decisions three days ago, it just adds more spaghetti on top of the sauce. You go around in circles, stuck in an…...

51+ min ago (634+ words) Events are often used to decouple logic and keep a system modular. Events allow for a very modular architecture. Your system emits events at different points in time and this allows you to create a completely independent and pluggable module which hooks into these events without needing to make any changes to the core part of your system. For example, you might create a Notification module which listens to various events in your system and sends e-mail, text messages, push notifications and performs other actions related to notifying your users. All of this without ever needing to change any part of your existing codebase. Your module can have a single responsibility, be completely self-contained and independent. For example, POS systems often have a local law requiring them to implement the payment system as a completely separate module. Without events and…...

1+ hour, 5+ min ago (641+ words) Localization in Flutter sounds simple on paper: "Just use ARB files, run the generator, and you're done." Right" until your app grows to hundreds of keys, multiple languages, different plural forms, nested folders, and a team of devs all touching the same translations. I've been there. And after a few years of building multilingual Flutter apps, I'm convinced of one thing: Localization is one of the most annoying parts of Flutter development. Even with tools like easy_localization helping us generate code and structure files, there are still several pain points that never went away for me. So I built a tool to fix them " but let me start with the problems first. JSON files are fine when you have: But with real apps, things turn into this: It gets worse when: LokiLoki uses a real tree editor, like you'd expect in…...
