Paydash
Paydash is a monitoring tool for block officials overseeing MGNREGA, India's employment guarantee programme for rural households. Beneficiaries under MGNREGA are supposed to be paid within 15 days of working, but the average worker waited 53 days to receive payment in 2014-2015, undermining MGNREGA's effectiveness as a social safety net.
Paydash aims to reduce delays in beneficiary payments by providing government officials with detailed information on delays -- breaking out performance on payment sub-processes down to the panchayat level and connecting poor performance with the responsible government employee. In addition to diagnostics, Paydash is action-oriented, providing access to pending documents and the contact information of the responsible employee. Paydash aims to empower government officials with better information while introducing more accountability into the payments process, with the ultimate goal of helping MGNREGA workers receive their rightful payments.
Paydash is a joint initiative of the Ministry of Rural Development, the National Informatics Centre, and Evidence for Policy Design at Harvard Kennedy School.

Application Structure
Let's take a tour of the app.
|
| -- app
| |-- controllers // Controllers are organised by module names
| | |-- <module_name> // Each controller defines config and handler for that route.
| |
| |-- helpers // Helper functions used across application
| |-- models // All sequelize models are defined here
| |-- routes // All app routes are defined here
| | |-- <route_plugin> // Route module is a hapi plugin and can be toggled from config/manifest.js
| |
| `-- templates // All server-rendered handlebar templates, partials and helpers
| |-- <module_name> // Templates are organised by module names.
|
|-- assets // Contains all static resources
| |-- fonts // Fonts used in application
| |-- images // Images used in application
| |-- misc // Misc resources used in application

|-- index.js // Application starting point
|-- package.js // Package configuration file
|-- server.js // Main server file
Code
We're using semi-colons and comma-last. No rhyme or reason; and some of the hapi code convention guidelines. All client-side js code is also in commonJS pattern packs using webpack. Check out .editorconfig, .jsbeautifyrc, .jshintrc for additional code conventions used.
Running the server locally
- Install
node,npm - Place a copy of
config.jsin/configfolder. - Monitoring services will require Google analytics service account key file placed in
config/keys/ - Run these commands
# Install deps
$ npm install
# Run the node server
$ npm start
# > [email protected] start /Users/ravisuhag/Batcave/Workspace/hks-epod/Dev/paydash
# > gulp
#
