Frontend

Django AI Assistant has a frontend TypeScript client to facilitate the integration with the Django backend.

Installation

Install the frontend client using npm:

npm install django-ai-assistant-client

Client Configuration

First, you'll need to check what base path you used when setting up the Django AI Assistant backend. The base path is the URL prefix that the Django AI Assistant API is served under. Below the base path would be ai-assistant:

myproject/urls.py

from django.urls import include, path

urlpatterns = [
    path("ai-assistant/", include("django_ai_assistant.urls")),
    ...
]

Before using the frontend client, import the configAIAssistant and configure it with the base path. If you're using React, a good place to do this is in the App.tsx file:

example/assets/js/App.tsx

import { configAIAssistant } from "django-ai-assistant-client";
import React from "react";

configAIAssistant({ BASE: "ai-assistant" });

Note in the configuration above, the Django server and the frontend client are using the same base path. If you're using a different base path, make sure to adjust the configuration accordingly.

Now you can use the frontend client to interact with the Django AI Assistant backend. Here's an example of how to create a message:

import { aiCreateThreadMessage } from "django-ai-assistant-client";

await aiCreateThreadMessage({
    threadId: 1,
    requestBody: {
        assistant_id: 1,
        message: "What's the weather like today in NYC?"
    }
});

Advanced Client Configuration

By default the frontend client is authenticated via cookies (CREDENTIALS === 'include'). You can configure the client differently. Below is the default config:

configAIAssistant({
    // Base path of the Django AI Assistant API, can be a relative or full URL:
    BASE: '',
    // Credentials mode for fetch requests:
    CREDENTIALS: 'include',
    // Record<string, unknown> with headers to be sent with each request:
    HEADERS: undefined,
    // Basic authentication username:
    USERNAME: undefined,
    // Basic authentication password:
    PASSWORD: undefined,
    // Token for authentication:
    TOKEN: undefined,
});

Client Functions

The frontend client provides the following functions:

aiListAssistants

List all assistants the user has access to.
Param: none
Return: a Promise that resolves to an Array of Assistant.

aiGetAssistant

Get an assistant by ID.
Param: { assistantId: string }
Return: Promise that resolves to Assistant.

aiListThreads

List all threads the user has access to.
Param: none
Return: a Promise that resolves to an Array of Thread.

aiCreateThread

Create a new thread.
Param: { requestBody: { name: string } }
Return: a Promise that resolves to a Thread.

aiGetThread

Get a thread by ID.
Param: { threadId: string }
Return: a Promise that resolves to a Thread.

aiUpdateThread

Update a thread by ID.
Param: { threadId: string, requestBody: { name: string } }
Return: a Promise that resolves to a Thread.

aiDeleteThread

Delete a thread by ID.
Param: { threadId: string }
Return: a Promise that resolves to void.

aiListThreadMessages

List all messages in a thread.
Param: { threadId: string }
Return: a Promise that resolves to an Array of ThreadMessage.

aiCreateThreadMessage

Create a new message in a thread.
Param:
{ threadId: string, requestBody: { assistant_id: string, message: string } }
Return: a Promise that resolves to void.

aiDeleteThreadMessage

Delete a message in a thread.
Param: { threadId: string, messageId: string }
Return: a Promise that resolves to void.

Note

These functions correspond to the Django AI Assistant API endpoints. Make sure to read the API documentation to learn about permissions.

Type definitions

The type definitions are available at frontend/src/client/types.gen.ts. You can import the schemas directly from django-ai-assistant-client root:

import {
    Assistant,
    Thread,
    ThreadMessage
} from "django-ai-assistant-client";

React Hooks

The frontend client also provides React hooks to streamline application building.

Warning

You still have to call configAIAssistant on your application before using the hooks.

useAssistantList

React hook to manage the list of Assistants. Use like this:

import { useAssistantList } from "django-ai-assistant-client";

export function MyComponent() {
    const {
        assistants,
        fetchAssistants,
        loadingFetchAssistants
    } = useAssistantList();
    // ...
}

useAssistant

React hook to manage a single Assistant. Use like this:

import { useAssistant } from "django-ai-assistant-client";

export function MyComponent() {
    const {
        assistant,
        fetchAssistant,
        loadingFetchAssistant
    } = useAssistant();
    // ...
}

useThreadList

React hook to manage the list, create, and delete of Threads. Use like this:

import { useThreadList } from "django-ai-assistant-client";

export function MyComponent() {
    const {
        threads,
        fetchThreads,
        createThread,
        deleteThread,
        loadingFetchThreads,
        loadingCreateThread,
        loadingDeleteThread
    } = useThreadList();
    // ...
}

useMessageList

React hook to manage the list, create, and delete of Messages. Use like this:

import { useMessageList, Thread } from "django-ai-assistant-client";

export function MyComponent() {
    const [activeThread, setActiveThread] = useState<Thread | null>(null);
    const {
        messages,
        fetchMessages,
        createMessage,
        deleteMessage,
        loadingFetchMessages,
        loadingCreateMessage,
        loadingDeleteMessage
    } = useMessageList({ threadId: activeThread?.id });
    // ...
}
