Setup Procedure

If you would like to reproduce our application locally and make any edits, please do the following steps:

Note: Please input your own Google API key. For documentation on how to get your own Google Maps API key: Google Developers

1. Clone the repository or download the project code to your preferred disk location.
2. Open two terminal windows and change the directory to the appropriate disk location.
3. Make a virtual environment for the project through conda or venv.
4. To install all packages needed, execute the command:

$ pip install -r requirements.txt

5. In one terminal window, change the directory to the frontend folder and download all the dependencies required by executing these commands:

$ cd frontend
$ npm install

6. There is a .gitignore file in our project, which contains the relative path of 2 files that conatins the Google Map API keys.

Create a config.jsx file in \frontend\pages\, and copy the code, inserting your API key in xxx.

export const config = {
    MAIN_API_KEY: 'xxx',
    PHOTOS_API_KEY: 'xxx'
}

Create a apikey.py file in \flask_app\, and copy the code, inserting your API key in xxx.

API_KEY = "xxx"
KEY = "&key=" + API_KEY

7. Please enable port: 3000 and port: 8000 for both inbound and outbound traffic in your network firewall.

Run the Project

1. Open two terminal windows and change the directory to the appropriate disk location.
2. In one terminal window, change the directory to the frontend folder and compile all frontend scripts, by executing these commands:

$ cd frontend
$ npm run dev

3. In another terminal window, execute these commands to start the Flask Server:

$ cd flask_app
$ python3 app.py

4. Copy the URL generated by the npm into a web browser in your machine, the application should be working. Some examples of the URL:

http://localhost:3000
http://127.0.0.1:3000
http://192.168.1.2:3000

Google Cloud Platform Tools Used

APIs [Please enable these APIs during the Setup procedure]:

• Google Maps JavaScript API - Used to embed the interactive map layout to the interface

Compute Engine: Host all services from frontend and backend in an always-on Virtual Machine instance [Not needed for localhost]

Languages Used

Python - Backend algorithm to obtain locations, calculate best meetup location. Communications between the backend and frontend
Javascript ES6 - Dynamic web development for the frontend

Packages Used

Algorithm:

• requests
• pandas
