langchain-examples

This folder contains examples of how to use LangChain.

Run an example

What you'll usually want to do.

First, build langchain. From the repository root, run:

pnpm install
pnpm build

Most examples require API keys. Run cp .env.example .env, then edit .env with your API keys.

Then from the examples/ directory, run:

pnpm run start <path to example>

eg.

pnpm run start ./src/prompts/few_shot.ts

Run an example with the transpiled JS

You shouldn't need to do this, but if you want to run an example with the transpiled JS, you can do so with:

pnpm run start:dist <path to example>

eg.

pnpm run start:dist ./dist/prompts/few_shot.js
