Truffle is a framework for DApp development. It’s to not be confused with truffle-contract, a library, and abstraction for smart contract interaction, almost like Web3.js. Truffle is great because it is often the inspiration to the distributed app development with Unit Testing and continuous integration style workflows. The Website: 40Thttp://truffleframework.com/40T. It’s three things especially that are worth highlighting:
1. Built-In Smart Contract Compilation, Linking, Deployment, and Binary Management.
We will very quickly realize in Ethereum, that there are multiple compiler implementations for solidity. And if you’re having multiple contracts which require to be linked together, a team that’s performing on them on a development chain, then a group path for deployment and compilation is what we are literally trying to find.
2. Automated Contract Testing for Rapid Development
3. Network Management for Deployment
With multiple blockchains and multiple developers, it’s always good,
How does truffle work?
This should install truffle globally. Remember, truffle and npm don’t have an automatic update mechanism, so we’d need to update the truffle manually from time to time. This usually means uninstalling and re-installing the truffle. As we will see, the version that got installed is “4.1.11”. Sometimes, when things aren’t working as expected, it’s an excellent idea to roll back to a special version. This will be done by specifying the version number during installation: npm install -g 40Ttruffle@4.0.040T would install truffle version 4.
Let’s quickly discuss the truffle directories:
When we initialize a replacement project with truffle init in an empty folder, then truffle will download a scaffolding project from GitHub and unpack it. The project is going to be initialized with a default structure, these are the important folders in every truffle project:
The “contracts” folder is where the smart contracts are located. These are the Solidity files.
