I Built StackLens — A Simple Log Aggregation Dashboard

Logs are one of the first things developers check when something goes wrong. But when logs come from multiple services, they quickly become hard to manage.

To explore how centralized logging works, I built StackLens — a full-stack log aggregation dashboard.

The idea is simple: services send logs to a backend API, the logs are stored in PostgreSQL, and a web dashboard lets you search, filter, and analyze them.

Tech Stack

I started with PERN stack , i don't know much about technologies yet ,still exploring though.... but according to you what stack is best suitable for this that if we think about scaling this project ? i would love to hear your opinion.

Frontend

React
TypeScript
TailwindCSS
TanStack Query
React Router

Backend

Node.js
Express
PostgreSQL
Supabase (hosted Postgres)

What schema i used ?

Each log entry looks like this:

{
  "service": "auth-service",
  "level": "info",
  "message": "User authenticated successfully",
  "metadata": { "ip": "192.168.1.10" },
  "timestamp": "2026-03-02T11:39:16Z"
}

Why I Built This

The goal of this project was to practice building a real-world style dashboard that combines:

backend APIs
database design
frontend data fetching
responsive UI design

Even though it's a simplified system, it helped me understand how log monitoring tools work behind the scenes.

What I Learned

Building StackLens helped me practice:

designing filtering APIs
using PostgreSQL enums and JSONB
managing server state with TanStack Query
building responsive dashboard layouts

Thanks for reading!, love to hear if you build something similar.

Chatgpt is heavier or is that a bug ?

hello devs,
i was recently using chatgpt for a while and i got a surprise that when i try to open and start chats old chats which have a lot of conversations in it of course and suddenly my entire RAM was on the fire that my laptop started to freeze down. may be this is because chatgpt's DOM ,but they must optimize.
Also switching chats is good option but it still misses topic and goes out of context, better if they provide a summary option which help keeping track of context. What do you think ?
