Truffle Configuration

Here is the truffle-config.js script for this project.

module.exports = {
    networks: {
        development: {
            host: "127.0.0.1",     // Localhost (default: none)
            port: 7545,            // Standard Ethereum port (default: none)
            network_id: "*",       // Any network (default: none)
        },
    },

    // Configure your compilers
    compilers: {
        solc: {
            version: "0.8.1",    // Fetch exact version from solc-bin (default: truffle's version)
            ...
        }
    },
};

We can configure blockchain networks under networks in truffle-config.js file. This development network contains our Ganache local blockchain network configurations. We can specify the network we need to deploy our smart contracts using network keyword at the deployment time as follows.

truffle migrate --reset --network development

This command deploys our smart contracts in to the development network.

Next we configure the compilers for the project. We use 0.8.1 compiler version in our project.
