a basic node.js template to run langchain.js
All you need to do is
-
add your OpenAI API key to the
.envfileOPENAI_API_KEY=YOUR-KEYand -
run the app with the following command
npm install && npm run dev
After that, you can edit the app.ts file to change the prompt.
app.ts uses langchain with OpenAI to generate a code snippet, format the response, and save the output (a complete react component) to a file.
- install dependencies
npm init es6 -y && npm install langchain openai dotenv @types/node
- setup node project
typescript ts-node
npx tsc --init --rootDir src --outDir ./dist --esModuleInterop --lib ES2020 --target ES2020 --module nodenext --noImplicitAny true
- Update Package.json
"scripts": {
"build": "tsc",
"start": "node ./dist/app.js",
"dev": "ts-node --esm ./src/app.ts"
},
- Create app.ts in the src folder.
mkdir src
echo "console.log('Welcome to the LangChain.js tutorial by LangChainers.')" > src/app.ts
- boot up
npm run build
npm run start
I followed this Blog post tutorial to setup the initial node environment.
