Reverse-Engineer Any Competitor's Posting Schedule with Node.js

Your competitor posts 4 times a week. Their engagement is consistently 3x yours. Is it the content? Maybe. But what if it's when they post? Timing matters more than most developers think. The algorithm doesn't just evaluate content quality — it evaluates initial engagement velocity. Post when your audience is online, and you get that early boost. Post when they're asleep, and your content is buried before anyone sees it. I built a tool that analyzes any creator's posting history and extracts their exact schedule — day of week, hour of day, and which time slots get the best results. Here's the whole thing. The Stack Node.js – runtime SociaVault API – fetch post history with timestamps Statistics – frequency analysis, heatmap generation Step 1: Fetch Post History const axios = require ( ' axios ' ); const API_BASE = ' https://api.sociavault.com/v1 ' ; const API_KEY = process . env . SOCIAVAULT_API_KEY ; const api = axios . create ({ baseURL : API_BASE , headers : { ' x-api-key ' : API_KE
