Learn ASP.NET Core Web API From Scratch By Building Real-World Library API

In this comprehensive tutorial, you will learn ASP.NET Core Web API from scratch by building a production-ready, hierarchical School Library API. Instead of the usual basic CRUD tutorials, we dive deep into complex, real-world back-end business logic.
We will manage three essential database entities: Users, Books, and Profile Updates, and implement an advanced user hierarchy where Admins, Teachers, and Students each have unique, restricted data privileges.
You will see exactly how to structure your project using Data Transfer Objects (DTOs), handle database migrations seamlessly with Entity Framework Core, and secure your endpoints using JSON Web Tokens (JWT).
We will also walk through the process of building custom middle-ware to handle errors globally, giving you a back-end architecture that matches what professional developers use in the industry.

-------------------------------------------------------------------------------------
What Will You Learn:
• Advanced Role-Based Authorization: Learn how to restrict endpoints using strict hierarchical logic where Teachers can manage Students, and Admins hold absolute system control.
• Many-to-Many Relationships: Master Entity Framework Core by designing a custom reading list system where students can add or remove books from their personal collections.
• Approval Workflows: Implement a secure profile update queue that tracks approvals and rejections, including custom notes from moderators.
• Production-Grade Middleware: Code a global exception handling middleware from scratch that hides dangerous stack traces in production while logging full errors in development.

This is the complete, unfiltered story of React — from a frustrated engineer's experiment inside Facebook's broken ad system, to the framework powering over 11 million websites worldwide. From being called "a step backward for web development" at JSConf 2013, to becoming the most used frontend framework on the planet.
We cover everything. The chaos that created it. The controversy that nearly killed it. The decisions that defined it. And the questions that still surround it in 2026.

Hello Everyone👋

I built an Android app 📱. It's a free photo editor called Framify — lets you post
your full photos without cropping them. And in version 2.0, we made it even better by adding these features:

✅ Bug Fixes
✅ Improved Design
✅ Added Fonts (15 Fonts)
✅ Flip horizontal/vertical
✅ Rotate 90° left/right
✅ Brightness/Contrast/Saturation sliders
✅ Image sharpness slider
✅ 5 new aspect ratios (2:3, 1.91:1, A4, Letter, Custom)
✅ 3 new sticker packs (Travel, Food, Fitness)
✅ Text alignment (left/center/right)
✅ Text background color with opacity

Would mean a lot if you downloaded it and gave it a review!

18 - State Management: Complex State Objects, Derived Rune, Universal Reactivity (.server.ts pages)

In Part 18 of our SvelteKit course, we are moving beyond the basics and diving into State Management in Svelte 5. The old "store" pattern is a thing of the past. Svelte 5 introduces Runes, a unified reactivity system that makes managing data cleaner, faster, and more intuitive.

We build a Team Task Manager from scratch to demonstrate how to handle complex data structures without the headache of immutable spreads. You'll learn how to keep your UI in perfect sync using $derived and how to architect professional-scale apps using Universal Reactivity in .svelte.ts files.

Speed up your JavaScript code by running tasks in parallel, not one by one https://amzn.to/3LWiuTb

Most developers still use sequential awaits… but real performance comes from mastering Promise.all().

If you want your apps to load faster and your APIs to respond quicker — this is a must-know trick.

Level up your async game with cleaner, faster, modern JavaScript. 💛🔥
