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
With immutable smart contracts on the chain, the one thing you would like to try to do is a test, test, and test again. Truffle makes unit-testing with the built-in testing framework including the event chain a breeze. We‘ll test in JavaScript and Solidity.
3. Network Management for Deployment
With multiple blockchains and multiple developers, it’s always good,

How does truffle work?
Truffle may be a javascript library that’s supported NodeJs. So, to put in and run truffle you’d got to install Node and therefore the Node Package Manager (NPM) first. you’ll find Node for all platforms on this website: 40Thttps://nodejs.org/en/40T After installing Node you’ll attend any command-line interface (Terminal on Mac/Linux or PowerShell on Windows) and interact with npm. Install truffle by typing in npm install -g truffle.
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 [email protected] 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.
In the “migrations” folder are the principles and scripts to deploy the contracts within the “contracts” folder. Contracts aren’t deployed automatically, you want to write a rule for the deployment of every and each solidity file. within the “test” folder is both, the JavaScript and Solidity test files. Then there are two js-files, the “truffle.js” and therefore the “truffle-config.js” file. Both are identical, the “truffle-config.js” file is usually necessary on windows because its naming conflicts with the executable file “truffle”.

Truffle Box
One project from the truffle framework worth mentioning is “Truffle Box”. These are pre-configured “mini scaffolding projects” which make starting a replacement distributed application a breeze. We can find an inventory of truffle boxes here: 40Thttp://truffleframework.com/boxes/40T. If we start with vanilla javascript or Vue, React, Angular, we will begin with a truffle box. to urge a truffle box, for instance, the online pack box, just types in truffle unbox web pack. this may download, unpack and initialize the GitHub repository here: 40Thttps://github.com/truffle-box/webpack-box40T. It’s basically equivalent to cloning the repository and running “npm init”.
