    Conceal-API: Javascript/Node.js interface (RPC/API)

    Javascript/Node.js interface to Conceal cryptocurrency RPC/API.

    There are three RPC servers built in to the three programs conceald, concealwallet and walletd. They can each be started with the argument --help to display command line options.

    conceald

    A node on the P2P network (daemon) with no wallet functions; console interactive. To launch:

    $ ./conceald
    

    The default daemon RPC port is 16000 and the default P2P port is 15000.

    walletd

    A node on the P2P network (daemon) with wallet functions; console non-interactive. To launch, assuming that your my.wallet file is in the current directory:

    $ ./walletd --container-file my.wallet --container-password PASSWD --local --bind-port 3333
    

    The wallet functions RPC port is 3333. The default daemon P2P port is 15000. The default daemon RPC port is 16000. The --local option activates the daemon; otherwise, a remote daemon can be used.

    concealwallet

    A simple wallet; console interactive unless RPC server is running; requires access to a node daemon for full functionality. To launch, assuming that your my.wallet file is in the current directory:

    $ ./concealwallet --rpc-bind-port 3333 --wallet-file my --password PASSWORD
    

    The wallet functions RPC port is 3333. By default the wallet connects with the daemon on port 16000. It is possible to run several instances simultaneously using different wallets and ports.

    Quick start for node.js

    $ npm install conceal-api
    $ ./conceald # launch the network daemon
    $ ./concealwallet --rpc-bind-port PORT --wallet-file my --password PASSWORD # launch the simple wallet
    

    Create and run a test program.

    $ node test.js
    

    The test program could contain, for example, a payment via the simple wallet's RPC server

    const CCX = require('conceal-api')
    const ccx = new CCX('http://localhost', '3333')
    
    ccx.send([{
      address: 'ccx7Xd3NBbBiQNvv7vMLXmGMHyS8AVB6EhWoHo5EbGfR2Ki9pQnRTfEBt3YxYEVqpUCyJgvPjBYHp8N2yZwA7dqb4PjaGWuvs4',
      amount: 1234567
    }])
    .then((res) => { console.log(res) }) // display tx hash upon success
    .catch((err) => { console.log(err) }) // display error message upon failure
    

    API

    const CCX = require('conceal-api')
    const ccx = new CCX(host, walletRpcPort, daemonRpcPort, timeout)
    

    ccx.rpc returns a promise, where rpc is any of the methods below:
