Description

This tutorial will take you through the process of building your first dapp—an adoption tracking system for a pet shop!

This tutorial is meant for those with a basic knowledge of Ethereum and smart contracts, who have some knowledge of HTML and JavaScript, but who are new to dapps.

  1. In this tutorial we will be covering:
    1. Setting up the development environment
    2. Creating a Truffle project using a Truffle Box
    3. Writing the smart contract
    4. Compiling and migrating the smart contract
    5. Testing the smart contract
    6. Creating a user interface to interact with the smart contract
    7. Interacting with the dapp in a browser.

Pete Scandlon of Pete’s Pet Shop is interested in using Ethereum as an efficient way to handle their pet adoptions. The store has space for 16 pets at a given time, and they already have a database of pets. As an initial proof of concept, Pete wants to see a dapp which associates an Ethereum address with a pet to be adopted.

Truffle is a world class development environment, testing framework and asset pipeline for blockchains using the Ethereum Virtual Machine (EVM), aiming to make life as a developer easier. With Truffle, you get:

  • Built-in smart contract compilation, linking, deployment and binary management.
  • Automated contract testing for rapid development.
  • Scriptable, extensible deployment & migrations framework.
  • Network management for deploying to any number of public & private networks.
  • Package management with EthPM & NPM, using the ERC190 standard.
  • Interactive console for direct contract communication.
  • Configurable build pipeline with support for tight integration.
  • External script runner that executes scripts within a Truffle environment.
