Originally published on the Aniq UI blog.By the end of this guide you will know how to build an online course platform with recorded lessons, live classes, quizzes, certificates and paid checkout, using Next.js, NestJS and the Learnio LMS template from Aniq UI. You will not have to build a student site, an admin panel and an API separately.We follow one example school from its first plan to launch. Each step names the screen or setting involved, and the commands come straight from the template's

Why I didn't integrate with Messenger

A fitness coach I know runs live workouts in a private Facebook group. During each workout she says a password. Participants send it to her on Messenger, and after the session she goes through the messages and ticks off who was there.With dozens of messages after every workout, this takes time and mistakes are easy. And there are no statistics: who came on which day, who stopped coming. The request sounded simple: can an app read those messages for me? What Meta's APIs allowBefore writing a

Migrating from AngularJS to React: A 30% Performance Improvement Journey

Migrating a legacy application is rarely a walk in the park. It's often a complex dance between maintaining existing functionality, introducing new features, and, if you're lucky, improving performance. When we decided to tackle our aging AngularJS codebase, the promise of a snappier user experience with React was a huge motivator. And let me tell you, the 30% performance improvement we saw wasn't just marketing hype; it was a game-changer. Why Migrate? Beyond the HypeBefore diving into the

React and Next.js Avatar Uploads: Presigned URLs or a Backend for Private Storage?

A browser direct upload with a presigned URL is a good avatar path only when the React or Next.js production origin already works with the private object storage provider's CORS behavior. Large-file throughput makes direct transfer attractive; CORS decides whether it is viable.Short answer: proxy the first avatar or receipt-original upload through your backend, then move large files to presigned browser upload only after a production-origin test passes. This keeps the initial evaluation focused

Two Critical Next.js RCE Fixes Ship With No CVE ID. npm audit May Never Tell You.

On October 14, Vercel did something it rarely does: it shipped a Next.js release outside the normal schedule, dropping everything to push out fixes for two critical vulnerabilities. Both allow unauthenticated remote code execution. Both score 9.5 on the CVSS v4 scale. A high-severity denial-of-service flaw rode along in the same release.If you run a Next.js app and your only exposure signal is npm audit, here is the uncomfortable part. According to The Hacker News' coverage of the release, as of

Full-page screenshots that are actually complete: lazy loading, sticky headers, 100vh layouts and emoji

Disclosure: I build and sell one of the three screenshot tools compared below, a hosted screenshot Actor on Apify. This article was written with the help of AI; the numbers come from the public benchmark data linked at the end, and everything here works in a plain Playwright or Puppeteer script.page.screenshot({ fullPage: true }) looks done until you look at the output: blank rectangles where lazy images should be, the sticky header stamped down the page, a cookie banner across the middle, and e

Why seeking in Electron's video player stutters – and how I fixed it

I built a video player called Doggy Player because seeking in the players I tried always felt janky. When I moved to Electron, I hit the same problem in a new form: Chromium's <video> element is great at playing files and surprisingly bad at jumping around in some of them. This is what I found, and what I did about it. Why seeking is slowTo show a frame at an arbitrary position, a decoder has to start from the previous keyframe (IDR) and decode forward from there. If keyframes are 8 s

The Next.js 14 Awakens: Server Components Rise

The Quest Begins (The "Why")Honestly, I was tired of shipping React apps that felt like they were dragging a backpack full of rocks. Every time I added a new feature, the bundle grew, the first paint slowed, and users on slower connections stared at a blank screen while the JavaScript hustled to hydrate. I kept asking myself: Why do we have to send the whole UI to the browser just to render a bit of static markup? One late‑night debugging session (you know the kind—coffee cold, eyes blear

Free SEO Audit Crawler API: Automate Technical SEO Checks with JavaScript or Python

Desktop crawlers like Screaming Frog are excellent, but they're manual: open the app, crawl, export, repeat. If you manage several sites, run an agency, or want SEO checks in CI after every deploy, you want an SEO audit crawler you can call as an API and get JSON back.This guide shows how to do that with the SEO Audit Toolkit on Apify, from JavaScript, Python and curl, and how to turn the results into automated alerts. What the audit checksFor every crawled page:Title and meta description:

TypeScript 7 Upgrade Guide: What Breaks, ESLint, Next.js and Real Benchmarks

I tested the TypeScript 7 upgrade and ran into three catches that are easy to miss: removed tsconfig options, a typescript-eslint break, and a side-by-side setup that changes which compiler next build uses. Here is the full guide with the exact errors and fixes.TypeScript 7 is the native, Go-based rewrite of the TypeScript compiler, and it has been the latest version on npm since July 8, 2026. It type-checks the same code as TypeScript 6 but much faster. On this box Hono's source built 5.2x fast

Arbeitsagentur Jobsuche API: How to Get German Job Listings as JSON (2026 Guide)

The Bundesagentur für Arbeit (BA) Jobbörse is Germany's largest job board, with around a million live Stellenangebote. It is backed by a public REST API, often called the Arbeitsagentur Jobsuche API, that the official website and app use.This guide covers how that API works, where it gets awkward, and a ready-made way to get clean job data as JSON from JavaScript, Python or plain HTTP.

Google Trends API in 2026: How to Get Trends Data Programmatically (JS & Python)

If you have ever searched for a "Google Trends API", you probably found three things: an alpha API from Google with a waitlist, the unofficial pytrends library that keeps breaking with HTTP 429 errors, and a lot of scraping tutorials that stop working after a week.This guide shows a practical alternative: calling a hosted Google Trends scraper as an API. You send keywords, you get back clean JSON with interest over time, interest by region, related queries and related topics. I'll show JavaScrip

Build a Voice Notification System with ElevenLabs

Why Voice Notifications MatterWhen you’re building a real‑time application—think chat, alerts, or accessibility features—displaying a text banner just isn’t enough. A voice notification can grab attention, convey urgency, and reach users who are multitasking or visually impaired. The key to a polished voice experience is a high‑quality, expressive TTS engine that can even mimic a specific speaker. That’s where ElevenLabs steps in. Getting Started with ElevenLabsElevenLabs offers a rob

Native BigInt. Faster than decimal.js

You've probably seen this one:0.1 + 0.2; // 0.30000000000000004The usual answer is "just use decimal.js". And honestly, that's good advice. decimal.js, big.js and bignumber.js are great libraries. But they were all written before JavaScript had BigInt, so under the hood they keep digits in arrays and do every multiplication and division by hand, in JavaScript.That made me curious. What if a decimal library just handed the hard part to BigInt and let V8 do the work in native code?So I built bigin

Build a Slide-In Mobile Menu in TanStack Start with Tailwind v4

A mobile menu that pops in and out works, but it feels unfinished. In this article we turn it into a drawer that slides in from the right with a fading backdrop, using only Tailwind classes and no animation library. We also keep it usable for keyboard and screen-reader users, lock the page scroll while it is open, and respect the reduced-motion setting.This is part of the TanStack Start Basics series. It builds on the responsive Header and the separate NavLinks component from the previous part.

I built mcp-doctor — a free CLI + web tool that debugs your MCP servers in seconds

The problemYou add an MCP server to your Claude Desktop or Cursor config. It doesn't show up. No error. You stare at mcp_settings.json for 40 minutes.I've been there. The failure modes are boring and invisible: a typo in mcpServers, a missing package name for npx servers, a command that's not on your PATH, a server that starts but dies during the handshake, tool schemas that are technically valid but broken at runtime.There is no standard tool to just... check it. So I built one. mcp-

Create an AI Dubbing Tool for Video Content

Why Build Your Own AI Dubbing Tool?If you’ve ever needed to localize a video, add a narration track, or simply replace a shaky on‑camera voice, doing it manually can be a nightmare. Traditional dubbing requires hiring voice actors, booking studios, and spending hours syncing audio to video. With modern text‑to‑speech (TTS) and voice‑cloning tech, you can automate most of that workflow in a few lines of code.In this post I’ll walk you through a practical, end‑to‑end pipeline for creating an
