Things people build with this

USE CASE 1

Build a hackathon project in 24 hours without setting up authentication from scratch.

USE CASE 2

Launch a startup MVP with user accounts, login, and payment processing already wired up.

USE CASE 3

Add AI features like chatbots or semantic search to your web app using pre-configured LangChain examples.

USE CASE 4

Integrate third-party services like Stripe, Twilio, or Google Maps without writing boilerplate code.

In plain English

Hackathon Starter is a boilerplate, a pre-built starting point, for Node.js web applications, designed to eliminate the hours of setup work that happen before actual product development can begin. The name comes from hackathons, where teams have only 24-48 hours to build a project and cannot afford to spend the first few hours configuring authentication, email, and APIs from scratch. The boilerplate ships with a comprehensive set of pre-built features so you can clone the repository, configure a few environment variables, and immediately start building the unique parts of your idea. The most valuable pieces are the authentication system (local email/password login, passwordless login, passkeys, and OAuth 2.0 sign-in with Google, Microsoft, Facebook, LinkedIn, GitHub, Discord, and others), full user account management (profile editing, password reset, email verification, two-factor authentication, and account deletion), a contact form wired to email services, and file upload support. It also includes pre-built examples for AI features (an AI agent using the ReAct pattern with tool calling, RAG with semantic caching, and integrations with Llama, DeepSeek, and other models via LangChain), and example integrations with dozens of third-party APIs including Stripe, Twilio, Google Maps, Google Drive, GitHub, and stock data services. A "go to production" checklist is included to help you verify the app is ready for real users. You would use Hackathon Starter at the beginning of any new Node.js web project, especially when you need standard features like authentication and want to skip reimplementing them. It is equally useful at a hackathon or when bootstrapping a startup MVP. The tech stack is JavaScript on Node.js, using Express as the web framework, MongoDB as the database, and Bootstrap 5 for the frontend styling. Configuration uses environment variables.
