another page on my site! this is the most advanced one, and probably the last for a while as i switch over to gamedev for the summer!!

on this page you can search for specific characters, other artists who have drawn my characters, and lots of other tags i painstakingly added manually lmao

As a dev, can confirm.

I've used multiple dev- or sysadmin-oriented software without understanding what they were for, but they were needed by some other parts of the system.

Why Choose MongoDB Node.js for Web Development?

Using MongoDB Node.js in your projects enables fast data access, real-time processing, and seamless JSON handling. This duo is particularly popular for building RESTful APIs, single-page applications (SPAs), and data-driven web services.

JSON Everywhere: MongoDB stores data in BSON (a JSON-like format), and Node.js works seamlessly with JSON. This reduces the need for data transformation and simplifies backend development.

Asynchronous and Non-blocking I/O: Node.js handles multiple requests concurrently without blocking the thread. When paired with MongoDB’s asynchronous operations, this results in faster and more efficient applications.

High Performance at Scale: MongoDB’s document-based model is ideal for handling large amounts of unstructured or semi-structured data. Combined with Node.js, it can support high-throughput applications.

Easy Integration: The official MongoDB Node.js driver makes it easy to connect and interact with your database. Plus, popular frameworks like Express.js enhance the development experience.

Active Ecosystem: Both MongoDB and Node.js have large developer communities and strong documentation, which means better support and faster troubleshooting.

Why is the MERN Stack Dominating Modern Web Development?

Choosing the right tech stack is one of the most important decisions in any web development project — and MERN Stack has earned its place as a favorite for startups and enterprises alike.

💡 Why developers & businesses prefer MERN:

🔹 Full JavaScript Stack: One language from front-end to back-end simplifies development, speeds up project delivery, and reduces learning curves.

🔹 Scalable & Flexible: MongoDB’s schema-less NoSQL design allows smooth scalability as your project grows.

🔹 Performance-Driven: Node.js handles asynchronous requests with exceptional speed, boosting performance for real-time applications.

🔹 Component-Based Architecture: React helps create reusable UI components, resulting in faster, cleaner, and more maintainable code.

🔹 Strong Community Support: Backed by tech giants like Facebook (React) and open-source contributors worldwide, MERN remains future-proof and well-supported.

From eCommerce platforms and social media applications to enterprise dashboards and SaaS products — MERN Stack offers the versatility and reliability every digital project demands.

If you’re exploring tech stacks for your next web app, don’t overlook this combination! It’s fast, efficient, and perfectly aligned with modern business needs.

👉 Check out this insightful article from Rlogical Softtech to learn why MERN is a smart investment: https://www.rlogical.com/blog/for-what-reason-is-mern-stack-considered-the-best-for-developing-web-apps/

Future-ready. Developer-friendly. Business-approved.

Building full-stack applications with JavaScript has never been easier, thanks to the MERN Stack (MongoDB, Express.js, React.js, and Node.js). This powerful combination enables developers to build robust, scalable web applications entirely using JavaScript for both front-end and back-end development.

In this guide, we will walk you through the process of building a simple full-stack MERN app. By the end, you’ll have a working application with a React front-end that interacts with a Node.js back-end, using MongoDB for data storage. Let’s dive into the steps!
