Function for use of GPT Api for chat completion in Firebase

Firebase Cloud Functions for GPT Chat Completion

Example of ChatGPT implementation in Firebase with functions. They are via internal calls with call and response. Issue:: This method seems to be slower than the other Stream method because it does not stream.

SETUP

In functions folder create file .env with your OpenAI Api key.

Sample:

OPEN_AI_KEY="sk-<your key here>"

SETUP WITH CUSTOM FUNCTIONS FOLDER

To use functions in a custom folder different from the default, suppose the destination folder is functions inside we create a new folder named gpt-chat-completion and copy files from this project that are inside the functions folder. Then edit the firebase.json file from the root folder of your project.

{
	...
	"firestore": {
		...
	},
	...
	"functions": [
		{
			"source": "functions/gpt-chat-completion",
			"codebase": "gpt-chat-completion",
			"predeploy": ["npm --prefix \"$RESOURCE_DIR\" run lint"],
			"ignore": [
				"node_modules",
				".git",
				"firebase-debug.log",
				"firebase-debug.*.log"
			],
			"runtime": "nodejs16"
		}
	]
	...
}

Deploy

Run firebase deploy --only functions:gpt-chat-completion

Sample usage in REACT

import { httpsCallable } from "firebase/functions";
import {
	useFunctions,
} from "reactfire";
...
