This is a production-ready Node.js/Express web application boilerplate designed to jumpstart hackathon projects. The codebase implements a complete user authentication system supporting local email/password, OAuth 2.0/OAuth 1.0a (10+ providers including Google, Facebook, GitHub, Discord, Microsoft), WebAuthn passkeys, and two-factor authentication (TOTP + email). It includes session management with MongoDB, CSRF protection, rate limiting, and custom security measures like timing-safe token comparisons and IP-bound token consumption. Beyond auth, it ships working demos for ~20 third-party API integrations (Stripe, Twilio, GitHub, NYT, Wikipedia, etc.) and AI features powered by LangChain and Groq, including a ReAct agent with SSE streaming, a RAG pipeline with vector search, and LLM-based classification/vision. The repository also provides a sophisticated Playwright-based e2e testing framework using nock-recorded HTTP fixtures, enabling deterministic offline tests without live API keys. All features are organized as deletable modules with a removal checklist to facilitate trimming for production use.
This repository, microsoft/WhatTheHack, is a comprehensive collection of hackathon challenge content focused on Microsoft Azure technologies. It contains over 70 individual 'hacks' covering topics such as Kubernetes, AI, DevOps, serverless, infrastructure-as-code, and more. Each hack includes student challenge instructions, coach solutions, and often starter code and infrastructure templates. The repository serves as a reusable library for running hands-on workshops and self-paced learning. While not a single application, it provides a structured framework for creating and delivering technical training events. The code quality varies across challenges, but the overall organization and documentation are strong, with reusable patterns like GitHub Actions workflows and hack authoring templates.
