Configuration and Setup

Let’s get your local environment ready to run our chat application. Follow these steps carefully!

1. Fork and clone the repository or download it as a zip file and unzip it on your machine.
2. Open the project in your preferred code editor.
3. Launch your terminal and split it into two to run both server and client separately.

Setting Up the Client

1. In the first terminal, navigate to the client directory: cd client
2. Create a .env file in the root of your client directory and supply the following credentials:

   REACT_APP_GOOGLE_CLIENT_ID= 
   REACT_APP_SERVER_URL=http://localhost:8000

3. Acquire your Google ClientID for authentication from the credential page. If you’re new, start by creating a new project.
4. Follow these steps on the credentials page:
   • Click “Create credentials” and select “OAuth client ID”.
   • Choose the Web application type and name your OAuth client.
   • Set your redirect URL: http://localhost:3000 and http://localhost:3000/login
   • Copy the Client ID to your .env file.
5. Run the following commands in your terminal:

   $ cd client
   $ npm install (to install client-side dependencies)
   $ npm start (to start the client)

Setting Up the Server

1. In the second terminal, navigate to the server directory: cd server
2. Create a .env file in the root of your server directory and supply the following credentials:

   PORT=8000
   URL=
   SECRET=
   CLIENT_ID=
   BASE_URL=http://localhost:3000

3. Run these commands in your terminal:

   $ cd server
   $ npm install (to install server-side dependencies)
   $ npm start (to start the server)

Troubleshooting Ideas

If you encounter issues during setup, here are some troubleshooting tips:

• Ensure both client and server are running on the correct ports.
• Double-check that all environment variables are accurately defined in your .env files.
• Verify that your Google credentials are set up correctly in the Google Cloud console.
• If you face CORS issues, ensure that the server has the proper CORS settings to allow requests from your client.
