generative-ai-with-javascript

Microsoft's JavaScript-based generative AI course teaches developers how to build AI-powered applications through hands-on lessons, video tutorials, and a companion app featuring historical character interactions. It covers fundamentals from LLMs and prompt engineering to advanced topics like RAG and Model Context Protocol.

What generative-ai-with-javascript is

Educational repository providing JavaScript/Node.js code examples, lessons, and a web app demonstrating generative AI concepts including prompt engineering, structured output extraction, RAG integration, tool calling, and MCP server implementation. Uses GitHub Models and supports local model execution.

Quickstart

Get the generative-ai-with-javascript source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/microsoft/generative-ai-with-javascript.gitcd generative-ai-with-javascript# follow the project's README for install & configuration

Need it deployed, integrated, or customized instead? DEV.co ships production installs.

Best use cases

Learning GenAI fundamentals for JavaScript developers

Structured progression from LLM basics through advanced patterns (RAG, tool calling, MCP) with hands-on code examples, assignments, and video reinforcement for teams new to generative AI.

Building prototype AI applications with JavaScript

Use lesson code and companion app as scaffolding for proof-of-concepts, system prompt design, and structured output handling without vendor lock-in (GitHub Models support).

Team onboarding and internal training programs

Leverage structured lessons, quizzes, translations (community-contributed), and video content to standardize AI literacy across development teams.

Implementation considerations

  • Content is educational; plan for internal customization and proprietary data integration before production use.
  • GitHub Codespaces setup is convenient but requires GitHub account; local Node.js environment is alternative (setup documented).
  • Companion app requires specific data structures; verify alignment with your historical/domain data before adapting.
  • Dependencies on external model providers (GitHub Models, Azure AI, Ollama); evaluate cost, latency, and compliance for your use case.
  • Lessons reference specific model outputs and behaviors; results may differ with newer model versions or different providers.

When to avoid it — and what to weigh

  • Production-ready enterprise AI platform needed — This is educational material, not a production framework. No built-in monitoring, versioning, rate limiting, multi-tenancy, or enterprise deployment patterns.
  • Require guaranteed API stability or SLA support — Course uses external services (GitHub Models, Azure AI, Ollama). No guarantees on model availability, API changes, or support contracts.
  • Deep expertise in non-JavaScript AI stacks required — Content is JavaScript-focused. Python, Java, or Go teams will find limited direct applicability despite conceptual overlap.
  • Need offline-first or air-gapped deployment — Most lessons assume online access to GitHub Models or Azure services; local Ollama examples exist but are supplementary.

License & commercial use

MIT License. Permissive open-source license allowing unrestricted use, modification, and distribution for commercial and private projects, provided the license notice is retained.

MIT License is a standard permissive OSI-approved license. Code, lessons, and derivatives may be used commercially without restriction. However, this is educational content; any commercial product built from it must include its own development, testing, support, and compliance review. Verify that derivative works comply with any third-party service terms (GitHub Models, Azure AI, Ollama) used in your commercial offering.

Security considerations

Educational material; security hardening is not addressed. Consider: API key rotation and secure storage, input validation and injection prevention for user-provided prompts, output filtering for sensitive model responses, compliance with model provider ToS (data privacy, retention), and encryption for any local data or embeddings storage. Responsible AI disclaimers are present but do not constitute a security assessment.

Alternatives to consider

DeepLearning.AI short courses (Python-focused)

Similar educational structure with video + code; stronger focus on LLM theory; Python primary; commercial partnerships with cloud providers.

Vercel AI SDK + documentation

Production-focused JavaScript/TypeScript framework for AI apps; lighter on fundamentals, heavier on framework-specific patterns and deployment.

LangChain.js official tutorials

Framework-specific; covers RAG, tool calling, and agent patterns; more opinionated architecture; integrated community examples.

generative-ai-with-javascript FAQ

Can I use this in production?
Not directly. It is educational material. You may adapt and extend the code for production, but you must add error handling, monitoring, authentication, compliance checks, and proper API management. Plan for security review and testing.
What models does this support?
Examples use GitHub Models (free tier), Azure AI models, and local Ollama. No vendor lock-in; lessons are adaptable to OpenAI, Anthropic, or other providers with minimal changes.
Do I need Azure or paid services?
No. GitHub Models provide free tier access in Codespaces; Ollama examples run locally. Azure and paid cloud services are optional for advanced lessons.
Is the companion app production-ready?
No. It is a demo to illustrate concepts. It has a hardcoded historical character set and does not handle at-scale user management, logging, or compliance.
