Representing the entity relationship diagram informally:

erDiagram  UserChatList  }|--||  Chat  :  includes  UserChatList 
{  
	string  userId   
	array  chats  
}  Chat || -- || ChatMemory : has Chat  
{  
	string id
	updatedAt  time
} ChatMemory }| -- || Msgs : includes ChatMemory  
{
    string chatId
    string userId
    string title
    array messages
    string path
    string shared
    time createdAt
} Msgs  
{
    string role
    string content
}

Create .env file. You will need to use the environment variables defined in .env.example to run the Marketing Chatbot.

Note: You should not commit your .env file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.

🚨 When configuring Github's OAuth App. Homepage URL and authorization callback URL should look something like the following:

Homepage URL: http://localhost:3000
Authorization callback URL: http://localhost:3000/api/auth/callback/github

npm i --legacy-peer-deps
npm run dev

Your app template should now be running on localhost:3000 🎉🎉🎉
