Eth Gas Price Visuals

Live Example

A composable boilerplate for writing Ethereum dapps in a similar environment to what the MetaMask developers use themselves to develop MetaMask.

Forked from my older react-hyperscript-beefy-boilerplate, which is not Ethereum specific.

Purpose

I've been contributing to MetaMask for a while, and I wanted to make a web dapp with ethjs that used a similar build system.

My friend Jared said it was a nice little framework, and I should do a better job of sharing it.

It also crossed my mind that this framework could be good practice for onboarding MetaMask contributors.

Features

• Adds an instantiated ethjs object onto the state object for easy ethereum interaction.
• Uses react-hyperscript with Babel for an Elm-like Javascript ES6 experience.
• The sample project detects presence of the web3 API, and suggests downloading MetaMask in its absence.
• Features a simple tip button transaction, to show how easy it is to send a transaction and indicate loading state and errors.

Usage

Installation

Have node.js installed, then in the project folder:

npm install

Development

To run with live-reloading via beefy:

npm start

To build:

npm run build

This will generate a bundle.js file that is pointed to by the index.html.

Project Structure

./index.html                    <- The entry point for the app
./index.js                      <- The JS init entry point for the app, unbuilt.
./app                           <- The usually edited react views
├── root.js                     <- The home page, which could host routing, and has full state.
└── template.js                 <- Copy this to create views with full state access.
├── components                  <- The components that rely on local state
│   ├── download-metamask.js    <- A sample local React component, with customized style params!
│   └── template.js             <- Copy this to create your own components
./lib
├── reducers
│   └── index.js                <- The root React Redux reducer file.
└── store.js                    <- The redux store, instantiated with thunk and logging.
./bundle.js                     <- The built JS bundle, generated by `npm run build`.

To Dos:

• Add nice style sheet management, like SASS.
• Add unit test suite
• Add browser test suite (testem?)
