Mkdirs

A downloadable web-development project bundle from GreatStack for building a full-stack AI website builder with MongoDB, Express.js, React.js, and Node.js. The project includes starter assets and source files for a React website generator that accepts text prompts, builds websites step by step, exposes generation progress, and supports manual source-code editing, follow-up AI prompts, exporting, and publishing. Its tutorial project includes user authentication, REST APIs, an OpenRouter model integration, and an agent chat API for updating generated projects.

Nimbus is an open-source documentation-site scaffolder by Cloudflare that builds Astro sites directly in a repository. It writes layouts, components, styles, routes, content collections, and theme tokens as editable source files, while its plumbing is provided through npm packages. The generated sites include agent-readable Markdown and MDX page twins, llms.txt and llms-full.txt files, JSON-LD, sitemaps, robots.txt, per-page Open Graph images, full-text search, theming, accessible navigation, and optional versioned documentation. Nimbus also provides a registry for adding editable components, utilities, and agent-handoff recipes to an existing project. Sites produce static output for deployment anywhere, with Cloudflare as a first-class target, and include prose, structure, MDX, and configuration validation. The project is built on Astro, Sätteri, Tailwind, and optionally React; its README describes it as work in progress and pre-1.0.

Next.js is an open-source React framework developed by Vercel for building full-stack web applications. It extends React with server rendering, static-site generation, hybrid rendering, components, and routing, and integrates Rust-based JavaScript tooling for builds. The project provides documentation, a learning course, a showcase, community discussions, and contribution guidelines.

PortalJS is an open-source, AI-native framework maintained by Datopian and its community for building data portals. Its agentic skills advise on storage, compute, catalog, access, hosting, and metadata, then scaffold the result as plain, editable Next.js code. Claude Code skills can create a portal, add CSV or JSON datasets, connect to backends such as CKAN, and deploy it; generated portals include a home page, catalog, and dataset showcase, with support for configurable data providers, charts, maps, and schemas. A bare template is also available without the AI skills, and the project presents Git, object storage, Parquet, and DuckDB as an optional modern architecture while retaining traditional datastores as supported choices.

A minimal chatbot starter built with Next.js, the AI SDK, shadcn/ui, shadcn/react, shadcn/typeset, and the Vercel AI Gateway. It provides streaming chat with Markdown rendering, provider-native web search, tool calling, and a human-in-the-loop questionnaire in which the model can ask clarifying questions. The chat route streams responses with `streamText`, while the interface renders assistant messages as typed parts for text, GitHub repository lookups, web searches, questionnaires, and source URLs. Tool definitions are kept in separate files and composed through a central index; tool-part components display progress, results, errors, answered questions, and deduplicated search citations. Vercel deployments authenticate to the AI Gateway through OIDC, while local development uses an AI Gateway API key. The public unauthenticated chat route includes request validation, model restrictions, output and step limits, and client-disconnect handling, but the README recommends adding rate limiting, spending limits, and authentication before exposing it to real traffic.
