Usage

Within Javascript

Purse connects to its database using knex.js and bookshelf.js. All records must be signed by the signing key.

var purse = new PowerPurse({
  signingKey: '<RSA512 SIGNING PUBLIC KEY>',
  bookshelf : bookshelfJsObject,
  knex      : knexDbConnection
})

Promise<Account> purse.accounts.register({
  uid: '13lkjl2k34jlk3j4jijzlij'
})

Promise<Account> purse.accounts.find({
  uid: '13lkjl2k34jlk3j4jijzlij'
})

Purse<Balances> purse.account.getBalances()

Purse<Balance> purse.account.getBalance({
  currency: 'BTC'
})

Promise<Debit> purse.account.debit({
  amount    : 150,
  currency  : 'BTC',
  uid       : '<SOME_PAYMENT_HASH>',
  network   : 'ripple',
  nonce     : 12344,
  datetime  : '<TIMESTAMP>',
  signature : '<JSON_WEB_TOKEN>'
})

Promise<Credit> purse.account.credit({
  amount    : 100,
  currency  : 'BTC',
  uid       : '<SOME_PAYMENT_HASH>',
  network   : 'ripple'
  nonce     : 12345,
  datetime  : '<TIMESTAMP>',
  signature : '<JSON_WEB_TOKEN>'
})

Promise<Overdraft> purse.account.credit({
  amount    : 250,
  currency  : 'BTC',
  uid       : '<SOME_PAYMENT_HASH>',
  network   : 'ripple',
  nonce     : 123456,
  datetime  : '<TIMESTAMP>',
  signature : '<JSON_WEB_TOKEN>'
})
