How does InMemoryChatHistory works?

[sanjayojha]

How does one can pass previous user responses and assistant responses in chat? Consider I am creating a simple chatbot, and I want to send all previous responses from user and assistant ([["role" => "assistant", "content" => $aiResponse], ["role" => "user", "content" => $userResponse]]) during the chat session for the context. How can I do this?
I can see you have AssistantMessage.php and UserMessage.php but they are sending Single response, no preservation of old conversation.

At this stage the default chat history is "in memory". It keeps messages in memory only during the current session.

With this "in memory" history implementation you can't resume the conversation later in time.

In order tu support your use case I released a patch to accept an array of messages instead of a single message to be able to feed the agent with a previous conversation. (composer update to get the latest version)

Here is an example passing an array of messages into the chat() method:

$response = MyAgent::make()
    ->chat([
        new Message("user", "Hi, I work for a company called Inspector.dev"),
        new Message("assistant", "Hi Valerio, how can I assist you today?"),
        new Message("user", "What's the name of the company I work for?"),
    ]);
    
echo $response->getContent();
// You work for Inspector.dev

Another option is to implement a new chat history that support your use case (Database, Redis, etc). Take a look at the documentation.

Implementing a chat history to support your use case is the way to not rewrite the same code to restore a previous conversation again and again. But it always depends by your scenario.

Let me know if it works for you, or feel free to send a PR if you make some history implementation.

Ok this make sense now.
I will check it with a session based chat history for small use case.

Hi @sanjayojha the FileChatHistory was just released. It makes you able to persist conversations.

Just update the composer dependencies to get the latest version.

@ilvalerione got it. Will take a look. Thanks again.
