MagicBox must be running (and run its setup)
If you don' have token: NODE_ENV=development nodemon server.js
npm install. Use Node 5.6.0; we suggest following NVM instructions for any
OS.
Copy config-example.js to config.js. It should be good out-of-the-box,
but take a look to see if you need to edit anything.
[deprecated] Add your email address to whitelist array
Concurrently run both nodemon server.js and make dev. The former is the
actual server, and the latter watches for changes and rebuilds front-end
files.

Mocha frontend tests use Mocha (to organize test suites and such) within the
browser, to test components as they modify the DOM. You can either run these by
simply going to localhost:8080/test.html, or running make phantomjs-tests
(which uses Docker, suitable for running tests automatically via the command
line).
The new code path uses React, and P.js-based models (simple object-oriented classes). The relationship between views and models is like,
The design principles here are:
Stateless views: A huge tip for keeping front-end design clean is to keep state out of views (or controllers). Jason Merrill at Desmos mentioned that one could aim to model all view state, even animation, to reduce bugs.
Separation of views and models: All models are instantiated at root-level and passed down to views through props. If this ever becomes unwieldy, we should just make meta-models (models that contain other models). This obviously goes with the former, but also makes it effortless to shift around view structure. Different views require the same state, e.g. the date-picker references the currently-selected date, and also have the map reference the currently-selected date.
divis_kind: division kind - Any polygon that can be drawn on a map. Kinds inlcude: admin, cell.
country_iso: ISO 3166-1 alpha-2 ? two-letter country codes
Called from function: fetch_matrix_then_draw
Fetches diagonal of the mobility matrix. i.e. the number of people who've made two calls from the same tower. We think this is a measure of population density. It's a dynamic estimate. It changes from day.
Currently fetches matrix for one single day
The max value of the Diagonal of matrix is used to normalize all diagonal values. These values are used in the opacity of polygon colors to represent population density.
Called from function: fetch_geojson_for_divisions
Fetches geojson for either admin 2 polygons or voranoi cells to be displayed on map.
TODO(mikefab): Change 'division' to 'geojson'
