Uses the css framework bulma and font-awesome for icons.

TodoList

• Truffle Test
• User Registry Contract
• Basic Front End
• Design Auth Contract
• Add front-end for authentication
• Add component for viewing files for self, use bulma table.
• Boilerplate for Front-end testing
• Add component for viewing files for other users
• Deploy Contracts to main net and then upload a few files.
• Load different colours based on network
• Improve Form Validation and UI
• Try to add drizzle-front-end testing for components, this ought to be fun, maybe write an medium article about this.
• Add Contact Us Page, FAQ Page, etc ...
• Polish app, adding loading icons or render bulma icons, or font-awesome loading icons, add Contact Page.

Prereqs

1. node / npm and/or yarn
2. Ethereum Browser (metamask or coinbase wallet)
3. Static hosting (github pages and/or surge)
4. truffle, ganache-cli

Installation

1. Install Truffle and Ganache CLI globally. If you prefer, the graphical version of Ganache works as well!

   npm install -g truffle
   npm install -g ganache-cli

2. Download the box. This also takes care of installing the necessary dependencies.

   truffle unbox drizzle

3. Run the development blockchain, we recommend passing in a blocktime. Otherwise, its difficult to track things like loading indicators because Ganache will mine instantly.

   // 3 second blocktime.
   ganache-cli -b 3

4. Compile and migrate the smart contracts. Note inside the development console we don't preface commands with truffle.

   compile
   migrate

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

   // Serves the front-end on http://localhost:3000
   npm run start

6. Truffle can run tests written in Solidity or JavaScript against your smart contracts. Note the command varies slightly if you're in or outside of the development console.

   // If inside the development console.
   test
   
   // If outside the development console..
   truffle test

7. Jest is included for testing React components. Compile your contracts before running Jest, or you may receive some file not found errors.

   // Run Jest outside of the development console for front-end component tests.
   npm run test

8. To build the application for production, use the build command. A production build will be in the build_webpack folder.

   npm run build

Other doxity options

  "interaction": {
    "network": "2",
    "providerUrl": "https://morden.infura.io/sign_up_to_get_a_hash"
  },
  // option to whitelist various data
  "whitelist": {
    // the keyname `all` will be used for whitelist defaults
    "all": {
      "abi": true,
      "methods": true,
      "bytecode": false, // bytecode is false or undefined, it won't be shown
      "source": false // source is false or undefined, won't be shown
    },
    "DigixMath": {
      "source": true // source code uniquely shown for this contract, bytecode still hidden
    }
  }
