React‑Powered Authentication: JWT, OAuth, and Firebase Auth Demystified
Debugging a Midnight Login Bug in Medellín It was just past midnight in Laureles when my coffee‑starved brain met its match: a freelance client in Tokyo couldn’t log into our staging site. Their React SPA kept flashing invalid token even after a hard refresh. Turns out my local clock drifted four minutes behind Firebase’s server […]
Real‑Time React: Implementing WebSockets Without the Headaches
“Ping‑Pong Debugging” Before Sunrise in São Paulo I was hunched over a hostel balcony at 4 a.m., chasing the only stable Wi‑Fi in Vila Madalena. Luisa, a junior dev still awake in Madrid, couldn’t see live typing indicators in our pair‑programming tool. Each keystroke should broadcast through a WebSocket, but the stream dribbled to a halt whenever she […]
Data Fetching in React: useEffect vs. SWR vs. React Query
A Debug Session in Bogotá’s Dawn It was 5 a.m. in Bogotá, the sky still indigo above Monserrate. I was screensharing with Diego, a freshly minted boot‑camper in Lisbon, untangling a dashboard that blinked “Loading…” forever. He’d wired plain React useEffect calls straight to a flaky API; every tab change re‑fetched the same payload, crushing his […]
Building a Drag‑and‑Drop Interface with React & Pragmatic Drag and Drop
Pair‑Programming at 2 a.m. in Medellín The neon glow from my apartment in El Poblado was just bright enough to light the call with María, a junior dev dialing‑in from Manila. We were debugging a React Kanban board that refused to reorder tasks without flinging them into JavaScript limbo. After ten bleary‑eyed minutes we swapped out […]
The New Storefront: Pinia vs. Vuex for State Management in Vue.js
Hook — 05 : 57 a.m., Medellín ↔ Tulum refactor sprintA power‑flicker rattled my Colombian apartment just as Sofía, coding from a beachfront hostel in Tulum, DM’d: “Our Vuex boilerplate doubled since we moved to Vue 3, and TypeScript is screaming.” Minutes later we spiked the same feature in Pinia. Setup shrank from 120 lines to 35, hot‑module reload worked […]
Speed Without Sweat: Lazy-Loading, Suspense, and Code-Splitting in Vue.js
Hook — 06 : 08 a.m., Bogotá ↔ Playa Venao deploy watchA morning storm rattled my apartment in Colombia just as María, on Panama’s Pacific coast, pinged: “Largest bundle jumped to 1.2 MB—users on 3 G bail before first paint.” We traced it to an eager-loaded charting library lurking behind a tab. In forty minutes […]
Vue’s Swiss-Army Knife: Mastering Named, Scoped, and Dynamic Slots in Vue.js
Hook — 06 : 07 a.m., Medellín ↔ Panamá City code jamDamp mountain air drifted through my window as Luis, pair-programming from a rooftop cowork in Panamá, complained, “Our card component needs a custom footer on one page, but not the others — and props are turning into spaghetti.” Ten minutes later we replaced a […]
Code Once, Re-use Everywhere: Crafting Reusable Composables in Vue.js
Hook — 05 : 59 a.m., Santo Domingo ↔ Bogotá sprint retroThe Caribbean sunrise backlit my balcony when Camilo in Bogotá sighed over Zoom: “Why does every feature toggle fetch user prefs separately?” We’d copied the same watcher into five components. Coffee in hand, I spiked the duplication by extracting a tiny useFeatureFlags() composable, published […]
Shooting Portals in Vue 3: Mastering the teleport Component
Hook — 05 : 46 a.m., Medellín ↔ São Paulo refactor sprintA thunder-soaked dawn rattled my Colombian desk when André, coding from a rooftop café in São Paulo, messaged: “Our modal renders inside a overflow:hidden parent—half the tooltip is chopped off.” We had two options: rip apart layout CSS or beam the modal into the […]
Inclusive by Design: ARIA Roles & Keyboard Navigation in Vue.js
Hook — 05 : 55 a.m., Cartagena ↔ Mexico City QA blitzTropical birds screeched outside my Colombian balcony when Elena, testing from a cowork in CDMX, discovered that our slick Vue.js dashboard trapped focus inside a hidden sidebar. Her screen reader repeated “button, button” until she force–quit Chrome. Ten minutes, a <nav role=”navigation”>, and a […]
