Getting Started

Built With

• Angular5 - The web framework used
• Web3j - Integration with Ethereum client
• Truffle - The most popular development framework for Ethereum
• Bootstrap - Bootstrap is an open source toolkit for developing with HTML, CSS, and JS.

Prerequisites

Check first for at least node 9.2.0, npm 5.5.1:

nodejs -v
npm -v

npm is bundled with Node.js, so to install npm you only need to install Node.js on your Ubuntu/Debian

curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
sudo apt-get install -y nodejs

Installing

1. Fork this repo by clicking Fork button in top-right corner of this web page. Continue to follow instruction steps from your own ethereum-voting repo.
2. Clone your own "ethereum-voting" repo. Copy the link from the "Clone or download" button near the top right of this repo's home page.
3. The rest of these steps must be done from your machine's command line. See the Run Dapp or Deployment section to continue if you already have the repository installed.

For OSX and Linux

1. From the desired directory you wish to copy the "ethereum-voting" folder with source files to.

   git clone {paste your own repo link here}
   

   NOTE: Please use develop branch for contributing.

   git clone -b develop {paste your own repo link here}
   

2. Change directories to proposal-scheme:

   cd ethereum-voting
   

3. Make sure you have the pre-requisites NodeJS (v8.4.0 or higher) and npm (5.4.1 or higher) installed.

4. Install dependencies from within proposal-scheme directory:

   npm install
   

5. That is it, you are now ready to run the proposal-scheme dapp! Head to the Run dapp section for further instructions.

Run Dapp

For local node using truffle follow these steps.

truffle develop

Inside the truffle console write,

compile
migrate

Run the webpack server for front-end hot reloading (outside the development console). Smart contract changes must be manually recompiled and migrated.

Serves the scheme front-end on http://localhost:4200

npm start

If port already in use error run

sudo lsof -t -i tcp:4200 | xargs kill -9

Running the tests

TODO: Add testing coverage

truffle test

Local Development with TestRPC

Change your environment variable in truffle.js to your desired host and port.

  networks: {
    development: {
      host: 'localhost',
      port: 8545,
      network_id: '*' // Match any network id
    }

In a new terminal execute testrpc

testrpc

Recompile and migrate your truffle contracts to this development node

truffle compile

truffle migrate

Start your client.
