dedop / dedop-sandbox

DeDop experiments and prototypes

dedop-sandbox

Contains DeDop Experiments and Prototypes:

• backend - Hosts the DeDop RESTful API and WebService dedopws, which is implemented as a Falcon web app run in a CherryPy web server.
• frontend - Hosts DeDop GUI dedopgui which is implemented as an electron Desktop application and depends on the WebService dedopws running on localhost.

backend

Build and run

1. Install Python 3.4.
2. Install required libs

    $ pip install h5py-2.5.0-cp34-none-win_amd64.whl
    $ pip install falcon
    $ pip install CherryPy

3. Run

    $ cd backend
    $ python setup.py develop
    $ dedopws <L1A-data-dir>

Open browser and point to

• Falcon is a ridiculously fast, minimalist Python WSGI web framework for building cloud APIs and app backends. See http://falconframework.org/
• CherryPy, a reliable, HTTP/1.1-compliant, WSGI thread-pooled webserver. It's 100% Python, and can even be used by Jython. See http://www.cherrypy.org/
• Gunicorn, another popular Python Web Framework. Heavily relies on Unix, no Windows support as of version 19. See http://gunicorn.org/

frontend

Build and run

0. Kill the dedopws if it is still running. The frontend will start a new dedopws process on its own (see config below).
1. Install latest Node.js to get node's package manager npm.
2. Download Cesium-1.17 and unzip into frontend/Cesium-1.17
3. Create local file frontend/dedop-config.json but don't add this file to git! Adjust configuration parameters except the one for "serverAddress":

    {
      "serverAddress": "http://127.0.0.1:8080/",
      "serverScript": "C:\\Python34-amd64\\Scripts\\dedopws.exe",
      "serverArgs": ["D:\\EOData\\DeDop\\L1A"],
      "openDevTools": false
    }

3. Run

    $ cd frontend
    $ npm install
    $ electron .
