LangChain TypeScript quickstart
Follow the live docs — do not invent an alternate API from memory:
https://docs.langchain.com/oss/javascript/langchain/quickstart
Fetch that page (Docs MCP or HTTP) and implement what it shows (weather agent + createAgent). Requires Node 22+.
Local setup constraints
Apply these on top of the quickstart (they keep setup minimal and model-agnostic):
- Ask which provider/model to use. Showcase that LangChain is model-agnostic. Suggested prompt:
Which model should this agent use? Pass aprovider:modelstring — e.g.openai:gpt-5.5,anthropic:claude-sonnet-5,google-genai:gemini-2.5-flash-lite. Default if you're unsure: `anthropic:claude-sonnet-5`.
Swap the quickstart's model string for their choice (or the default).
- Create a new directory (e.g.
langchain-agent/) and do all work there — do not pollute the open project.
- Only secret: the provider API key in
.env(gitignored). No LangSmith / Tavily unless they ask. Prefer they edit.envthemselves — don't paste keys into chat.
- Install the provider package needed for their model if the quickstart's base install isn't enough.
- Run the example, show output, then stop. Point to
langchain-fundamentalsfor next steps.
