Quick Start - Step 2

Step 2 : Install Truffle and Ganache

Truffle and Ganache provides a development environment, test framework, and asset pipeline for blockchains.

Install Truffle

Navigate to the truffle directory within the tutorial, and install its dependencies.

cd <tutorial-root>/truffle
npm install

Open the truffle-config.js file in the truffle directory. Locate the following part under networks. This part tells Truffle how to connect to our RegNet node.

module.exports = {
    // ...
    networks: {
        //...
        regtest: {
            provider: new PrivateKeyProvider(privateKey,  "http://127.0.0.1:4444"),
            host: "127.0.0.1",
            port: 4444,
            network_id: 33,
        }
        //...
    },
    // ...
};

Note that the value for privateKey has been hardcoded into the config file. This is something that you would not do normally. As this is a tutorial, and we are not on the main net, however, this is OK.

Install Ganache

Navigate to the ganache directory within the tutorial, and install its dependencies.

cd <tutorial-root>/ganache
npm install

For Ubuntu, you may see an error in the terminal: Gtk-Message: Failed to load module "canberra-gtk-module" To fix this, install the required GTK modules which also needs to be installed.

sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

Start Ganache.

npm start

Ganache is a GUI app, and starting it in this manner makes DevTools available.
