Peeping into the folders

Here are the important folders:

• app: This folder contains the JavaScript, HTML, and CSS files of your decentralized application. Notice how we have a folder for /javascripts and /stylesheets, and a root index.html file.

• contracts: This folder contains the smart contracts for your decentralized application. Notice the Solidity files ConvertLib.sol, MetaCoin.sol, and Migrations.sol.

• migrations: This folder contains the scripts to migrate and deploy our smart contracts properly to various Ethereum blockchains. You will see this in more detail in Chapter 4, Migrating Your Dapp to Ethereum Blockchains.

• tests: This folder contains the files with unit and integration tests. You will see this in more detail in Chapter 6, Testing Your Dapp.
