ChatGPT HTTP Web Service

Simple Express server to interface with ChatGPT. Uses chatgpt-api in the background.

Set Up

1. Install npm packages: npm install
2. Copy .env.example to .env
3. Enter OpenAI credentials into .env (please look through the main index.js source file first to understand how the credentials are being used)

Running

In the background, chatgpt-api is being used to interact with ChatGPT, which uses puppeteer to spawn a browser window. Meaning, a non-headless server that can display a browser window is required to run this.

1. Run with node index.js
2. Browser window opens, solve the reCAPTCHA
3. Done. Server is serving on localhost:3000. Endpoints:
   • POST /api/chat, accepts JSON data containing message to send to ChatGPT: {"message": "Hello world"}. Subsequent requests are followed-up by default.
   • GET /api/reinit to reauthenticate with OpenAI.
   • GET /api/reset to start a new conversation.

Issues

If puppeteer throws an error stating it can't find chrome.exe or whichever equivalent binary for your system, you might need to edit node_modules/chatgpt/build/index.js, around line 1060. Search for the path and point it accordingly to where your Chrome is located at.
