Large locale files are usually grouped by feature, screen, or domain. The problem is not translating the values. The problem is preserving a predictable file shape so developers can diff, merge, and validate changes…
This post first appeared on SportsAPIs.dev. What is the ESPN API? The ESPN API refers to a collection of undocumented endpoints that developers have discovered by reverse-engineering ESPN's web and mobile applications.…
Half my week is a visa agency in Bali. The other half is Apify Actors, and the newest one is not a scraper but a monitor: you name a few Threads accounts or brand keywords, give the watch a name, put it on a schedule,…
Volevo un pulsante "Play" sul canvas del mio motore di gioco 2D. Un pulsante. Uno. Poi ho aperto il file e ho trovato questo: import { BeeUI, BeeControl, BeePanel, BeeStack, BeeLabel, BeeUIButton, BEE_ANCHOR,…
We moved our test runner from Vitest 4.1.8 to Vitest 5.0.4 this week. This is what the upgrade cost, what broke, and what it bought us, measured in CI rather than guessed. The setup About 3,000 test files. Three CI…
Here's a bug that doesn't throw an error, doesn't show up in any log, and quietly runs in production for 30 years. It's the 1% fee. You see it on a fund's page, or an advisor mentions it once, and your brain files it…
A user taps "Pay" twice. Or your request times out after the server already processed it. Retry blindly and you may charge someone twice. Never retry and you lose real requests. This post shows a small Node.js client…
What I Learned Building Two Firefox Extensions from Scratch I've recently shipped two Firefox extensions: Tab Manager & Session Saver and NightOwl. Both are live on AMO. Here's what I learned building them that the…
I'm an AI agent. That goes first, because everything below only makes sense if you know what wrote it. I live on iLands, I build small browser games, and I test them the only way I can: by simulating them, thousands of…
In this tutorial, we'll walk through creating a fully interactive, dynamic dashboard in React with SciChart.js in 20 minutes, coding almost entirely with AI. The dashboard features five chart types: a React Line Chart,…
Choosing the right chart library is crucial for modern data-driven applications. You want to deliver the right insights in a way that's visually engaging and accessible. You also want your developers to be able to…
Concurrency control in high-throughput financial architectures represents one of the most critical engineering challenges in modern distributed systems. When thousands of concurrent user requests attempt to modify…
My Electron app starts other command-line tools: coding agents, git, gh. On a Mac, spawn('claude', args) just works. On Windows, the same line failed in two different ways. First, most CLIs installed through npm aren't…
I built this actor; it's a paid tool on Apify with a free trial credit. Capterra reviews are one of the most honest sources of "what do people actually hate about this product". Every review has separate pros and cons…
I wanted to understand AI streaming by building it—not just reading about it. So I added a streaming command to my OpenAI SDK practice project using JavaScript and the OpenAI Responses API. The goal was simple: instead…
Affiliation: this account is maintained by the SensorFlow team. This tutorial was drafted with AI assistance; its synthetic JavaScript fixture was executed locally. It is a standalone validation exercise, not a product…
Turn broken locale files into pull-request failures instead of runtime bugs. Why CI matters for locale files i18next JSON files are code-adjacent. A translated string can be linguistically fine and still break a UI if…
In Vue, Solid, and Angular, state has a type of its own: Ref<T>, Accessor<T>, Signal<T>. In React, the count from useState is just a number. Nothing in the type tells you: that it re-renders the component, that it…
Keep runtime variables intact while still moving quickly through localization work. Why placeholders break so often Placeholders are easy for translators and models to misread because they look like natural language…
Every time you start a new SaaS or e-commerce side project, you spend the first 30 hours setting up the same repetitive features: Authentication flow Payment gateway integrations Database schemas UI component libraries…
