After successful setup of Ganache, the following steps need to be performed in order to unpack the webpack Truffle box and run the MetaCoin project: 1.
First step is to unbox the webpack sample from Truffle: $ truffle unbox webpack Downloading…
How to Run a Local Ethereum Blockchain for Development (Part 2)
Commands: Compile: truffle compile Migrate: truffle migrate Test contracts: truffle test Run linter: npm run lint Run dev server: npm run dev Build for production: npm run build 2.
Edit the truffle.js file, if required, and change the port to where Ganache is running.
Note the settings provided in the preceding screenshot, Ganache settings: $ cat truffle.js // Allows us to use ES6 in our migrations and tests.
Now run the following command to compile all contracts: $ truffle compile This will show the following output: Compiling ./contracts/ConvertLib.sol…
Now, as we are using Ganache as a Web3 provider, we need to edit a file called app.js under app/javascripts/ to edit the connection settings, so that the application can connect to the local Ganache blockchain.
Open this file and edit the following code: // fallback – use your fallback strategy (local node / hosted node + in-dapp id mgmt / fail) window.web3 = new Web3(new Web3.providers.HttpProvider(“http://127.0.0.1:9545”));
Why This Matters for Blockchain Technology
Understanding Ganache settings is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
