How I Built It: Breaking the Vanilla JS Wall

I am an experienced web developer, and my journey into full-stack development started when I wanted to build a private social media platform called PixUp. I built it using pure Vanilla JavaScript. Soon, the codebase became heavily bloated, messy, and completely unmaintainable.

In early 2026, I tried again with a project called BlockSocial. I added complex features like JSONL exports, backup uploads, and post forks. It grew into a giant, complex system that normal users wouldn't understand, and as a solo developer, I couldn't maintain it alone.

I had to stop and ask myself: Why do my social media apps keep failing?
The answer was always the same: Verbose Vanilla JS.

The Dilemma & The Solution

When planning my next platform, Vlox, I evaluated my frontend options:

  • jQuery? Too legacy.
  • Modern Frameworks (React/Vue)? Too heavy for edge environments.
  • Vanilla JS? Too verbose.

I decided to take the best parts of each and engineer my own solution. I built NanoScript—a modern, ultra-lightweight JavaScript library designed for fluent DOM manipulation via a fast, method-chaining API. To make it even more powerful, I engineered custom plugins for it, including a live counter and Ghost State (which automatically saves what you type so you never lose a draft).

Bringing Vlox to Life

With NanoScript handling the frontend, I built Vlox as a clean, high-performance Minimum Viable Product (MVP). It features a robust Node.js/Express backend, MongoDB database storage, secure bcrypt hashing, XSS sanitization, and an optimized Sharp image processing pipeline.

Thanks to NanoScript, the frontend architecture is finally in a state that I can easily scale without hitting a wall of messy code.

What I Focused on This Weekend

  1. Repository Overhaul: Standardized the architecture for both Vlox and NanoScript to make them clean for the public.
  2. Examples: Wrote several example codes using NanoScript.
  3. Performance Audit: Verified that the NanoScript plugin architecture and Vlox's Express rate-limiting work flawlessly under pressure.
