What

Web Server

Build and serve heliopropa's visualizations. It's a flask webserver, serving d3.js plots written in livescript, which is just javascript with lots of sugar to make it palatable. It also gathers NetCDF data from AMDA, and serves it as CSV to the plotter.

Rationale

• Reading NetCDF from javascript is doable, but still very hacky.
• The bridge can handle pagination and collecting multiple NetCDF into one CSV.

How

Overview

• config.yml : the main configuration file.
• web/run.py : the front controller, holding most of the code.
• web/view/home.html.jinja2 : the HTML template.
• web/static/js/swapp.ls : most of the javascript client-side.

Install

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Develop

source venv/bin/activate
python web/run.py

Then, browse localhost:5000.
