@ducatus/ducatuscore-wallet-client NPM

ducatuscore-wallet-client

The official client library for ducatuscore-wallet-service.

Description

This package communicates with DWS Ducatuscore wallet service using the REST API. All REST endpoints are wrapped as simple async methods. All relevant responses from DWS are checked independently by the peers, thus the importance of using this library when talking to a third party DWS instance.

See Ducatuscore-wallet for a simple CLI wallet implementation that relays on DWS and uses ducatuscore-wallet-client.

Get Started

You can start using ducatuscore-wallet-client via NPM: by running npm install @ducatus/ducatuscore-wallet-client from your console.

Example

Start your own local Ducatuscore wallet service instance. In this example we assume you have ducatuscore-wallet-service running on your localhost:3232.

Then create two files irene.js and tomas.js with the content below:

irene.js

var Client = require('@ducatus/ducatuscore-wallet-client');


var fs = require('fs');
var DWS_INSTANCE_URL = 'https://localhost:3232/';

var client = new Client({
  baseUrl: DWS_INSTANCE_URL,
  verbose: false,
});

client.createWallet("My Wallet", "Irene", 2, 2, {network: 'testnet'}, function(err, secret) {
  if (err) {
    console.log('error: ',err); 
    return
  };
  // Handle err
  console.log('Wallet Created. Share this secret with your copayers: ' + secret);
  fs.writeFileSync('irene.dat', client.export());
});

tomas.js

var Client = require('@ducatus/ducatuscore-wallet-client');


var fs = require('fs');
var DWS_INSTANCE_URL = 'https://localhost:3232';

var secret = process.argv[2];
if (!secret) {
  console.log('./tomas.js <Secret>')

  process.exit(0);
}

var client = new Client({
  baseUrl: DWS_INSTANCE_URL,
  verbose: false,
});

client.joinWallet(secret, "Tomas", {}, function(err, wallet) {
  if (err) {
    console.log('error: ', err);
    return
  };

  console.log('Joined ' + wallet.name + '!');
  fs.writeFileSync('tomas.dat', client.export());


  client.openWallet(function(err, ret) {
    if (err) {
      console.log('error: ', err);
      return
    };
    console.log('\n\n** Wallet Info', ret); //TODO

    console.log('\n\nCreating first address:', ret); //TODO
    if (ret.wallet.status == 'complete') {
      client.createAddress({}, function(err,addr){
        if (err) {
          console.log('error: ', err);
          return;
        };

        console.log('\nReturn:', addr)
      });
    }
  });
});
