Building a GPT-3 Knowledge Base App (NodeJS)

Building a GPT-3 Knowledge Base App (NodeJS)

This is code for building a GPT-3 powered knowledge base application using Node.JS/JavaScript. It's and example from the book Exploring GPT-3. To deploy and run this code you'll need the following:

• An OpenAI API key
• An account on Replit.com (the free account will work)

Using this code

1. Watch the 2-minute tutorial video.

2. Click the 'Run on Replit.com' button below to copy this code to your Replit.com account.

   

3. In Replit.com, add a new secret named OPENAI_API_KEY and make the value your OpenAI API key.

4. Add your own content to the documents defined in the routes/answers.json file.

5. Run and test the app in Replit

Using an answers file

By default the code uses a JavaScript array of documents in routes/answers.json for the knowledge base. Alternately, you can store documents in an answers file. There is an example answers file named answers.jsonl in the root, along with a file named upload.js that provides code you can use to upload an answers file to the OpenAI API. If you use the answers file, you'll also need to setup a secret / environment variable named ANSWERS_FILE with the OpenAI filename for the value.

An array of documents is used by default because because it's simpler. However, there are two primary advantages to using a documents file. First, you can include more than 200 documents. Second, the the API will throw a 404 error if there isn't a matching result. Meaning, the app could be setup to log questions that should be added to the documents - unanswered questions. This is not currently a feature but is planned for a future release.

For more details on using answer files, see the OpenAI Documentation.
