A web-application showing historical Foreign exchange rates as a chart, and a prediction algo applied on it

How to run the web app?

The repo has an index.html and required static assets in designated folders. Serving the web-app would need a web-server. Any web-server would do, we'll use python's SimpleHTTPServer for demonstration.

1. Install Python (if you already have it, skip to next step):

   On a Mac: Most Macs come with Python 2.7 already installed, but it’s good to double-check the version. To determine whether you have Python 2.7, open the Terminal application, type the following, and press Return:

   python -V
   

   This command will report the version of Python:

   Python 2.7.3
   

2. Setup HTTPS:

   In order to serve this web-app over https://localhost/, we need to create a self-signed cert/key pair. To do that, run the following commands:

   cd ~/Desktop
   mkdir certs
   cd certs
   openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365
   ...
   ...
   

   On running the last command (openssl), it may ask for some user inputs. Just provide those and the following cert-key files should exist in youe ~/Desktop/certs/ directory:

      -rw-r--r--  1 <user>  1437157072  1208 Mar  8 08:00 cert.pem
      -rw-r--r--  1 <user>  1437157072  1858 Mar  8 08:00 key.pem

3. Edit server.py config

   Open the file server.py located at the root of this directory. Change the name of your system user in below lines:

    # Full path to the location of 'key.pem' file
    keyfile = "/Users/<username>/Desktop/certs/key.pem"
    # Full path to the location of 'cert.pem' file
    certfile = '/Users/<username>/Desktop/certs/cert.pem'
   

   Save the file after editing the file paths for cert.pem and key.pem (created in step:2 above) correctly.

4. Run the server

   We'll be running Python's in-built SimpleHTTPServer for our testing. The server.py file is for doing this job. Run the following command from the root directory of the web-app:

   python server.py
   

5. That's it!

   Now navigate to the below url in your favorite browser and you should see the web-application:
