An application that stores historical stock data into an InfluxDB database, uses Django as the backend framework for the API, and React as the frontend framework with Bootstrap.
Grafana and React both use Port 3000, and this application did not change the ports of either technology.
This application retrieves the 2018 historical data for a selected number of stocks from Quandl. Make sure that you have an API key from Quandl, and you can sign up for one here.
You will need to install a few of the above technologies. The install guide for each can be reached by clicking the name of the technology.
After the installation and cloning, you should install the Python3 packages needed by opening up the terminal in the home directory of the project and entering this:
> pip3 install -r requirements.txt
First, activate InfluxDB:
> make db
You will need to create an environment variable for the Quandl API Key:
export QUANDL_API_KEY='YOURQUANDLAPIKEY'
Then, open dbSetup.py and change the necessary parameters. More instructions will be in the file's comments. After this, you can run the setup file:
> python3 dbSetup.py
To test that the database has been set up correctly:
> make test
Now, all the data within the Database can be viewed in visual graphs using Grafana. Start Grafana using this command:
> make grafana
You can stop both services using this command:
> make stop
Before activating Django, go into /django_project/app/views.py and change the parameters similar to dbSetup.py. Next, create a new Django Secret Key and set an environment variable for it:
export DJANGO_SECRET_KEY="YOURDJANGOSECRETKEY"
You can get a new DJango Secret Key using the following Python code:
from django.core.management.utils import get_random_secret_key
print(get_random_secret_key())
Then, you can activate Django as the backend framework:
> make django
For more information about the API, press here for the Postman documentation.
Note that Cross Origin Access has been enabled for Port 3000 (React's port) using corsheaders.
Open up a new terminal and go into the react-app directory:
> cd react-app
Then, build the application to retrieve the necessary node modules:
> npm build
Now, you can activate React by:
> yarn start
or
> npm start
Now, http://localhost:3000/ should be the URL of your React application, and you can access it from an internet browser.
