Truffle on wsl

Copy UI Source Code

command

# you are in root dir of greeter project
cd ..
git clone https://github.com/RedSquirrelTech/hoscdev
cp -r hoscdev/chapter-5/greeter/client/ greeter/client

Change truffle-config.js

truffle-config.js

module.exports = {
  contracts_build_directory: "./client/src/contracts",
  networks: {},
  mocha: {},
  compilers: {
    solc: {
      version: "0.8.11", // Fetch exact version from solc-bin (default: truffle's version)
    },
  },
};

Start UI

command

# you are in root dir of greeter project
truffle compile
cd client
npm i
npm run start

I think your browser will give you an error, but that is not a problem at this time.

Setup Ganache

Install Windows client from Ganache.
Launch Ganache.

Choose vEthernet(WSL) and note the IP address. Then click SAVE WORKSPACE.

Setup MetaMask

Install MetaMask.

If you are logged in MetaMask, please log out once.
You click the import using Secret Recovery Phrase.

Copy the mnemonic from Gahache.

Paste the mnemonic into the recovery phrase and input password.

And create new network.
You can check the RPC URL on Ganache and Chain ID is 1337.

Add Development Network

host is same as Ganache RPC server.

truffle-config.js

module.exports = {
  contracts_build_directory: "./client/src/contracts",
  networks: {
    development: {
      host: "172.22.112.1",
      port: 7545,
      network_id: "*",
    },
  },
  mocha: {},
  compilers: {
    solc: {
      version: "0.8.11", // Fetch exact version from solc-bin (default: truffle's version)
    },
  },
};

Deploy to Dev Network

command

# in project root folder
truffle migrate --network development
# Compiling your contracts...
# ===========================
# ...
# Summary
# =======
# > Total deployments:   2
# > Final cost:          0.01683276 ETH

Launch web server.

command

# in project root folder
cd client
npm run start

If you log in to the development network with MetaMask, you should see a screen similar to the following
