CoAgent offers a set of tools required to integrate LanGraph agents into React applications in order to build native agent applications. In this post we will talk about this tool and see how one can build AI CoAgents or Copilot powered applications.

What is CoAgents?


As mentioned earlier, CoAgent is a set of tools that will allow you to integrate AI agents into applications for developing native agent applications. Let us now talk about some of its features.


Build AI CoAgents or Copilot-powered apps


Follow the steps listed below to build AI CoAgents or Copilot-powered apps.



Let’s see them in detail.

1] Installing CopilotKit


Before we get started with CoAgents, we first need to install CopilotKit on your device. We assume that you have already installed Node.js and npm on your computer and created a folder for React apps; however, the last part is optional for this step. CopilotKit uses an open-source LLM model; in this tutorial, we will be using the OpenAI API key. Without further ado, let’s get started.



cd C:\React\My\App



npm install @copilotkit/react-core @copilotkit/react-ui @copilotkit/runtime


Then, run the below-mentioned command to install OpenAI.


OPENAI_API_KEY=your_api_key_here


After making changes to the file, we recommend you navigate to docs.copilot.ai/quickstart to learn how to configure the endpoint and setup the CopilotKit provider in your project.

2] Configure the backend remote endpoint


To integrate Python-based services (or any other Node.js alternative), we need to connect the Copilot application to a remote backend endpoint. To do so, we first install the Copilot dependencies in Windows Terminal using the following query.


pip install copilotkit fastapi uvicorn --extra-index-url https://copilotkit.gateway.scarf.sh/simple/


Now, we need to configure the FastAI server, for that, run the commands mentioned below.


mkdir my_copilotkit_remote_endpointcd my_copilotkit_remote_endpointecho. > server.py


If echo didn't work, you can open the folder in Visual Studio Code and then create the server.py file.


Open the server.py file in VSCode and then paste the following lines of code.


from fastapi import FastAPI app = FastAPI() @app.get("/") def read_root(): return {"Hello": "World"}


Now, go back to Windows Terminal and install FastAPI and Uvicorn.


pip install fastapi uvicorn


Once you're done with that, head over to the docs.copilot.ai guides for more information.

3] Add LangGraph Agent


Next, we need to integrate the LangGraph agent into the server.py file. First, locate the CopilotKitSDK instance inside your Python remote endpoint, which is usually located in server.py. Next, adjust the CopilotKitSDK instance (set in the previous step) to accommodate the LangGraph agents. You need to add the following lines of code.


agents=[ Lanonfig={ # if you use Google Gemini, uncomment this code (and import `copilotkit_messages_to_langchain`, see above) # "convert_messages": copilotkit_messages_to_langchain(use_function_call=True) # } ) ],


This must be put under the tag CopilotKitSDK.
