HazelJS Agent-Based Business Intelligence Dashboard
A developer tutorial and demo showcasing a Business Intelligence dashboard built on HazelJS, an agent-based TypeScript framework. The system uses multiple specialized agents (DataInsightsAgent, ReportGeneratorAgent, RecommendationEngineAgent) coordinated by a BusinessIntelligenceOrchestrator to ingest data from multiple sources, run AI-powered analysis, generate reports and recommendations, and render real-time interactive visualizations (Chart.js). The open-source project includes a tabbed dashboard (Dashboard, Data Entry, Scenarios, Reports), CSV/JSON export, live updates every 30 seconds, and instructions to run locally (Node.js >=18, npm/yarn). The article includes code examples for adding custom agents, notes on architecture patterns (decorator routing, dependency injection), dependency requirements, and a GitHub repository link for the hazeljs-business-intelligence demo.

Key Takeaways & Evidence Grounding
- HazelJS is a TypeScript framework for building agent-based applications and was used to build the showcased Business Intelligence system.
- The demo BI system defines three core agents: DataInsightsAgent, ReportGeneratorAgent, and RecommendationEngineAgent, plus a BusinessIntelligenceOrchestrator.
- Dashboard features include real-time KPI cards, interactive Chart.js sales charts, filterable insights, pre-built scenarios, and CSV/JSON export.
- The dashboard refreshes automatically every 30 seconds and runs locally via Node.js (>=18) with npm or yarn; repository: github.com/nisafatimaa/hazeljs-business-intelligence.
- Required package dependencies (example) include @hazeljs/agent, @hazeljs/core, @hazeljs/eval (version ^0.8.7) and reflect-metadata (^0.2.2).

Surgical BI Dashboards with Next.js and Canvas
A developer article (published May 14, 2026) by Datta Sable describes building high‑performance, bespoke BI dashboards by combining Next.js 14 server components with HTML5 Canvas rendering. The piece argues that DOM‑heavy libraries (e.g., SVG/D3) fail at scale and that treating dashboards like a game engine—painting to a single pixel buffer and using framer‑motion for transitions—enables millisecond interactions and 60 FPS interactivity even with millions of data points. Two case studies are presented: a Global Sales Intelligence "Connectivity Mesh" visualizing revenue arcs across regions, and an EMI Collection Intelligence engine for loan portfolio risk/aging visualization. The article also covers UI techniques such as CSS variables for instant theme switching and advocates a “surgical” minimalist philosophy for executive-facing analytics.
AI Built App from 5-Line Memo in 45 Minutes
A developer published a demo showing an open-source framework, gr-sw-maker, which used multi-agent AI workflows to convert a five-line memo into a browser-only Earthquake Map application, a spec and tests in 45 minutes. The process relied on an agentic SDLC pattern with specialized AI agents (architect, security reviewer, test engineer, etc.), six quality gates, and an AI-native spec format (ANMS) that uses EARS, Mermaid and Gherkin. Deliverables included functional requirements, Gherkin scenarios, unit tests and high code coverage. The project is portable across several agent runtimes (Claude Code, Gemini CLI, Cursor, Windsurf) and requires Node.js and Claude Code to reproduce. The author frames this as Spec-Driven Development (SDD) within an agentic SDLC workflow.
Hermes Agent: Open-Source Self‑Improving AI Agent
This developer-focused article reviews Hermes Agent, an open-source autonomous AI agent built by Nous Research. The piece highlights Hermes Agent’s design priorities—persistent cross-session memory, reusable procedural skills, broad built‑in tool access (60+ tools depending on configuration), and support for multiple runtime backends (local, Docker, SSH, Daytona, Singularity, Modal). It describes fast onboarding (one-line installer and recommended hermes setup --portal flow), example developer workflows (research pipeline with search, extraction, summarization, and memory), trade-offs around complexity and observability, and why the project is worth watching as an agent framework that aims to improve over repeated use. The article is a submission to the Hermes Agent Challenge and includes links to official docs and the GitHub repo.
