List of events

Event bus provides a way to subscribe to events from any of the services running.
const eventBus = require('ocore/event_bus.js');

Wallet is ready (only headless wallet)

Headless wallet is needed for bots that hold private keys and can send transactions. This event is emitted when passphrase has been entered by bot admin and single wallet is loaded. Before that event, bot outputs device address, device pubkey and pairing key.

eventBus.on('headless_wallet_ready', () => {
});

Start database update

This event is emitted when bot executes series database queries to upgrade the database to new version.

eventBus.on('started_db_upgrade', () => {
});

End of database update

This event is emitted when bot finishes database upgrade.

eventBus.on('finished_db_upgrade', () => {
});

Connection to the hub via ws is established

eventBus.on('connected', () => {
});

});

Exchange rates are updated

This event is emitted when wallet updated rates that they got from Hub.

const network = require('ocore/network.js');
eventBus.on("rates_updated", () => {
console.log(JSON.stringify(network.exchangeRates, null, 2));
});

});

Unit saved

eventBus.on('saved_unit-' + unit, (objJoint) => {
});

Attempt to pair us with another correspondent

This event is emitted when there is a pairing attempt, this enables bot to decide with the code if the pairing code is valid or not. If you would like to accept any pairing code then there is easier solution.

eventBus.on("pairing_attempt", (from_address, pairing_secret) => {
if (pairing_secret == "SOME_SECRET") {
eventBus.emit("paired", from_address, pairing_secret);
}
});

Pairing was successful

This event is emitted on successful pairing (also when user removed and re-added the bot).

eventBus.on("paired", (from_address, pairing_secret) => {
let device = require('byteballcore/device.js');
// say hi to anyone who pair with bot
device.sendMessageToDevice(from_address, 'text', 'Hi!');
});

Pairing was successful using pairing secret

eventBus.on('paired_by_secret-' + body, (from_address) => {
});

eventBus.on("removed_paired_device", (from_address) => {
});

History update started

eventBus.on('refresh_light_started', () => {
});

History update finished

eventBus.on('refresh_light_done', () => {
});

A new message string type message has been received

This event is emitted when text message is received by bot.

eventBus.on("text", (from_address, body, message_counter) => {
let device = require('byteballcore/device.js');
// echo back same message
device.sendMessageToDevice(from_address, 'text', 'ECHO: '+ body);
});

A new message object type message has been received

This event is emitted when object message is received by bot.

});

Signing request

eventBus.on("signing_request", (objAddress, address, objUnit, assocPrivatePayloads, from_address, signing_path) => {
});

Signed event

eventBus.on("signature-" + device_address + "-" + address + "-" + signing_path + "-" + buf_to_sign.toString("base64"), (sig) => {
});

Refuse to sign

eventBus.on('refused_to_sign', (device_address) => {
});

Event for custom Request

You can add your own communication protocol on top of the Byteball one. See Request example there.

const network = require('byteballcore/network.js');
eventBus.on('custom_request', function(ws, params, tag) {
var response = 'put response here';
return network.sendResponse(ws, tag, response);
}

Event for custom JustSaying

You can add your own communication protocol on top of the Byteball one. See JustSaying example there.
