Mini Eth Browser

A simple ethereum block and transaction explorer. Since it doesn't use a database some operations are slow.

Setup

Install dependencies

npm install

Configuration

Edit src/config.js to point to a ethereum node.

Development

npm run dev

It uses nodemon and create-react-app script to reload changes.

Production

This may work but otherwise is not tested.

npm run build
npm run start

Organization

The project is divided in two parts backend and frontend.

• Backend is an Express application that serves a RESTful api.
• Frontend is a React application that consumes the backend api.

Both should be independent of each other, so it is easy to replace one without affecting the other.

Backend

The backend code is in src/ directory. Again it is split in two pieces:

• Routes Express routes that only have to deal with REST endpoints and parsing parameters. They should not dependant on Ethereum implementation details.

• Lib Code responsible to interact with Ethereum node and processing api. It is an abstraction above web3 library to return processed information ready to consume.

Frontend

The frontend code is in client/src/. It should be a standard React application.

• Components Reusable components that show varios Ethereum objects like transactions, blocks, accounts, etc.

• Controllers Old code to handle async request from views. It is being passed out.

• Lib Requests to interact with backend API.

• Utils Miscelaneus utilities.

• Views High levels blocks of the frontend.
