How to Direct Democracy

Prerequisites: Your development server's Latest version of nodejs, NPM, and Couchdb v2.0+ See common errors for installation of couchdb(CORS enablization and version 2)

Quick Install

git clone https://github.com/SIU-CS/Direct_Democracy-production.git
npm install
npm start

This should get a basic development server running. Open a browser and navigate to localhost:8080.

You can monitor all changes in the database through localhost:5984/_utils. Once you have node and couchdb set up, set up some bills to vote on by running. This will populate couchdb's 'bills' database.

node scripts/titleParsing.js

All the database responses are visible through console (ctrl+shift+c from Google Chrome).

Common Errors

• Node path issue, no packages are installed

Error Message looks like this:

npm ERR! Linux 4.4.0-77-generic
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "install"
npm ERR! node v4.2.6
npm ERR! npm v3.5.2
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn

This is an issue with node's path not being set, or being set incorrectly. You need to manually create a symlink /usr/bin/node. Shortcut for bash compatible shells:

sudo ln -s `which nodejs` /usr/bin/node

Or if you use non-standard shells, just hardcode the path you find with which nodejs:

sudo ln -s /usr/bin/nodejs /usr/bin/node

• Module not found during 'npm start'

Error Message Looks like this:

ERROR in ./src/redux/actions.js Module not found: Error: Cannot resolve module 'react-router-redux'

Oops! We used an npm package that didn't get automatically saved to our package.json. just npm install 'module' to resolve the error.

• CORS is not enabled on local development server

Error Message Looks like this:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https:localhost

CORS must be enabled for data to be transmitted between ports on localhost By default, this is off in Couchdb for security.

npm install -g add-cors-to-couchdb
add-cors-to-couchdb

• BadRequest, ReferHeader Error message looks like this:

  {"error":"bad_request","reason":"Referer header must match host."}

Make sure couchdb version 2.0+ is installed.

Happy hacking!
