Here is my truffle.js config, please I'm new to DApp development on the etherum blockchain.
const HDWalletProvider = require("#truffle/hdwallet-provider");
const infuraKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();
module.exports = {
networks: {
development: {
host: "127.0.0.1", // Localhost (default: none)
port: 9545, // Standard Ethereum port (default: none)
network_id: "*", // Any network (default: none)
},
rinkeby: {
provider: () => new HDWalletProvider(mnemonic, `https://rinkeby.infura.io/v3/${infuraKey}`),
network_id: 4, // rinkeby's id
gas: 4500000, // rinkeby has a lower block limit than mainnet
gasPrice: 10000000000
},
}
}
Please how do I fix this issue.
Thanks

Answer 1

truffle-hdwallet-provider is deprecated. It has been moved under the monorepo at trufflesuit/truffle. You should use that version. You can install it via
$ npm install #truffle/hdwallet-provider
In truffle-config.js
const HDWalletProvider = require("#truffle/hdwallet-provider");
