Install the package

via NPM

npm install ditcoin-wallet

Or clone the Github repository

git clone https://github.com/ditcoin/ditcoin-wallet-nodejs.git

Initializing a wallet

Require the module:

const DitcoinWallet = require('ditcoin-wallet');

Create a new instance of the wallet:

let wallet = new DitcoinWallet();

This creates a wallet using the following ditcoin-wallet-rpc default RPC settings:

• hostname - '127.0.0.1'
• port - 19092

To connect to a wallet with different settings, pass in the values:

let wallet = new DitcoinWallet($HOSTNAME, $PORT);

// or with rpc authentification needed
let wallet = new DitcoinWallet(HOSTNAME, $PORT, $USERNAME, $PASSWORD);

Note: versions of ditcoin-wallet-nodejs prior to 3.0 require hostname with the 'http://' prefix, 3.0 and greater only require the IP address.

Testing

Some basic tests can now be run locally to verify the library and your ditcoin-wallet-rpc instance are communicating. The tests assume RPC wallet will be listening at the default config settings. Tests are run via mocha. To run the tests, clone the repository and then:

npm install
npm test

Example Usage

wallet.getBalance().then(function(balance) {
    console.log(balance);
});

Run an Instance of the RPC Wallet

For internal communication through library and RPC wallet, following options are optional:

--rpc-bind-port
--rpc-bind-ip
--daemon-host
--confirm-external-bind

Note: more informations can be found using --help option.

Without authentification

ditcoin-wallet-rpc --password "$wallet_password" --wallet-file $wallet_filepath --rpc-bind-port 17092 --rpc-bind-ip $external_ip --daemon-host $external_ip --confirm-external-bind --disable-rpc-login

With authentification

ditcoin-wallet-rpc --password "$wallet_password" --wallet-file $wallet_filepath --rpc-bind-port 17092 --rpc-bind-ip $external_ip --daemon-host $external_ip --confirm-external-bind --rpc-login 'upxrpc_user:rpc_password'

Multi-wallets usage

ditcoin-wallet-rpc --password "$wallet_password" --wallet-file $wallet_filepath --rpc-bind-port 17092 --rpc-bind-ip $external_ip --daemon-host $external_ip --confirm-external-bind --rpc-login 'ditrpc_user:rpc_password' --wallet-dir $wallet_dirpath
