Tools for building and debugging with the Bilateral Transport Protocol (BTP)
Cat
BtpCat is used strictly for logging.
It can be used to display BTP packets, and the ILP packets inside them,
in a nice human-readable way. It's a single function that takes a JavaScript object, and
outputs a String so that eval(BtpCat(obj)) === obj. Example usage:
const BtpPacket = require('btp-packet')
const IlpPacket = require('ilp-packet')
const BtpCat = require('./src/cat')
const chalk = require('chalk')
console.log(chalk.bold.green('alice sends:'), chalk.green(BtpCat({
type: BtpPacket.TYPE_MESSAGE,
requestId: 4,
data: {
protocolData: [
{
protocolName: 'ilp',
contentType: BtpPacket.MIME_APPLICATION_OCTET_STRING,
data: IlpPacket.serializeIlpPacket({
"type": 6,
"typeString": "ilqp_by_destination_request",
"data": {
"destinationAccount": "de.eur.blue.bob",
"destinationAmount": "9000000000",
"destinationHoldDuration": 3000
}
})
}, {
protocolName: 'to',
contentType: BtpPacket.MIME_TEXT_PLAIN_UTF8,
data: 'us.usd.red.connie'
}
]
}
}, BtpPacket.BTP_VERSION_1)))
console.log(chalk.bold.red('alice receives:', BtpCat({
type: BtpPacket.TYPE_RESPONSE,
requestId: 4,
data: {
protocolData: [
{
protocolName: 'from',
contentType: BtpPacket.MIME_TEXT_PLAIN_UTF8,
data: 'us.usd.red.connie'
}, {
protocolName: 'to',
contentType: BtpPacket.MIME_TEXT_PLAIN_UTF8,
data: 'us.usd.red.alice'
}, {
protocolName: 'ilp',
contentType: BtpPacket.MIME_APPLICATION_OCTET_STRING,
data: IlpPacket.serializeIlpPacket({
"type": 7,
"typeString": "ilqp_by_destination_response",
"data": {
"sourceAmount": "10782788022",
"sourceHoldDuration": 5000
}
})
}
]
}
}, BtpPacket.BTP_VERSION_1)))Example output:
