Consider two sneaker listings that both contain 047. One contains CT8012-047 and the other contains 378038-047. The full identifiers correspond to the adult and Big Kids editions of the Jordan 11 Gamma. A suffix…
Checking one page's share tags is easy. You paste the URL into a checker, you read the title and the description, you fix what looks wrong. The problem I keep running into on client sites is not one bad page. It is…
Select a photo, simulate a failed upload, and select the same photo again. If the input still holds that file, the browser can treat the second selection as a cancellation, so a change handler may never run. For a…
If you built a Shopify integration before 2026, you probably clicked "Develop apps" in the store admin, copied a token that started with shpat_, and never thought about it again. That token didn't expire. New apps can't…
Moving a sofa is easy to represent as a coordinate change. Making that change safely reversible takes a little more care. Roomture, an AI interior design and room-planning app, lists undo among the improvements in its…
We build a point-of-sale and QR menu product for cafes and restaurants. One small feature is a TV menu: a public URL that the restaurant types into the browser of the smart TV hanging in the dining room. It shows the…
Single tool calls are easy to get working. The model reads your tool list, picks one, fills in the arguments, you run it, done. Real questions are rarely one call. "Where's the parcel for ayesha@example.com?" needs…
Lullwood, our free browser horror game built in three.js and Next.js, ships no audio files. Every sound in it is generated at runtime with the Web Audio API: looped noise buffers, oscillators, filters, gain targets and…
If you build websites for plumbers, dentists, law firms or any other local service business, structured data is one of the cheapest technical wins you can ship. A few lines of JSON-LD tell search engines exactly who the…
I've been quietly building Antigravity Tools — a collection of 59 free, browser-based developer utilities — and today I'm sharing everything I built and learned. Why vanilla JS? No React, no build step. The main…
Most browser puzzle portals treat a 5-minute logic break like an arcade slot machine: video interstitials between boards, flashing streak warnings, and cramped grids on mobile screens. When I started building Easy…
When preparing a 200-SKU supplier catalog for Shopify, Amazon, and Etsy, three tedious engineering headaches show up almost every single time: Vendor Excel sheets full of raw image URLs: Clicking 80 CDN links one by one…
Every "free passport photo" site I tried asked me to upload a photo of my face to a server I knew nothing about. Crop arithmetic does not need a server, so I built one that doesn't. Two weeks in, the traffic is close to…
Speech-language pathologists measure a child's MLU, mean length of utterance, by counting morphemes, not words. "Doggie jumped" is two words but three morphemes: doggie, jump, -ed. On a 50-utterance sample that counting…
Hey DEV Community! 👋 Managing customer support and recovering abandoned carts for e-commerce stores using traditional text-only chatbots often feels clunky. Customers drop off, issues get delayed, and midnight support…
A pattern shows up in a lot of front-end code reviews: some piece of data — a token, a cached profile, a license flag, sometimes even a "secret" configuration — is written to localStorage, and when someone objects, the…
Hibira speaks the Pusher Channels protocol. Your client libraries, server libraries, channel names, events and auth endpoints keep working. What changes is the host they connect to and the credentials they use. This…
Marketplace fees look simple until you try to put them in code. Some are percentages, some are fixed, they apply to different bases, and one of them depends on how the buyer found you. I built Fee Math, a set of free…
I started thinking about the Web Models API while experimenting with building AI-native GUIs. I was exploring the idea of UI as a function of AI: the model would generate the content and choose the component best suited…
Most Electron apps never touch native code: the renderer, the main process, and Node's built-in modules cover UI, networking, storage, and shell integration. The day comes when you need the other 1% — a fast image or…
