Tutorial: Build AI Discord Bots with NeuroLink

A technical tutorial that shows how to build a production-ready AI Discord bot using Discord.js and NeuroLink's generation API. The guide covers required npm packages and environment variables, setting up a Discord application and bot permissions, implementing slash commands (/ask, /chat, /summarize, /clear, /help), multi-turn conversation management with a 30-minute timeout, rate limiting, streaming responses, and error/security best practices. It includes complete example code (TypeScript), a NeuroLink service wrapper that calls a provider ('openai') with model examples (gpt-4o-mini / gpt-4o), and deployment options including Docker, Railway, Fly.io and DigitalOcean App Platform. The tutorial is practical and targeted at developers building conversational agents on Discord using NeuroLink as the AI backend.

Zero‑Downtime NestJS Deployments with GitLab and PM2

This is a hands‑on, production‑tested guide showing how to deploy a NestJS backend to a DigitalOcean Droplet with zero downtime. It covers Droplet initial setup (Ubuntu 24.04), installing Node.js v18 from the official binary, creating a non‑root deploy user, configuring Nginx as a reverse proxy and Certbot for SSL, and using PM2 in cluster mode with wait_ready/listen_timeout to enable graceful worker reloads. The article provides an ecosystem.config.js example, a GitLab CI/CD pipeline that rsyncs build artifacts and uses pm2 reload (or start) on the server, SSH key and GitLab variable setup, first‑time manual deploy steps, health checks, useful PM2/nginx commands, and a troubleshooting table of common issues and fixes encountered in a real production fintech deployment.
