WickrIO API Addon

Wickr's Node.js C++ Addon for a JavaScript API interface

Description:

This is the Node.js C++ Addon that provides access to Wickr's bot client. This WickrIO addon interface supports a set of Wickr client functionality that you can access via your Javascript code. You will be able to do the following Wickr operations:

• Send and receive messages and files
• Create, modify, leave, delete and configure secure rooms
• Create and leave group conversations

For full documentation please visit: https://wickrinc.github.io/wickrio-docs/#developing-integrations-node-js-addon-api

Before you can use the WickrIO addon, you will need to have Wickr's bot client. The WickrIO bot packages contain several sample bots that use this addon.

NOTE: versions 5.38.17 and older will require version 8 of node. Versions 5.44.2 and newer will require version 10 of node.

Usage and example:

Interaction with the WickrIO Node.js addon has the following sequence of operations:

1. You will need a "require('wickrio_addon') statement at the beginning of your javascript.
2. You will need to initialize the WickrIO Node.js addon interface, but calling the API's clientInit() function. This API requires the name of the WickrIO client as an argument. This identifies which client the addon will interact with.
3. Interact with the WickrIO client using the WickrIO Node.js addon APIs.

The following is an example of how to interact with the WickrIO bot client using the WickrIO Node.js addon and Bot API toolkit:

const WickrIOAPI = require('wickrio_addon');
const WickrIOBotAPI = require('wickrio-bot-api');
const WickrUser = WickrIOBotAPI.WickrUser;

process.stdin.resume(); //so the program will not close instantly

var bot, tokens, bot_username, bot_client_port, bot_client_server;
var tokens = JSON.parse(process.env.tokens);

async function exitHandler(options, err) {
  var closed = await bot.close();
  console.log(closed);
  if (err) {
    console.log("Exit Error:", err);
    process.exit();
  }
  if (options.exit) {
    process.exit();
  } else if (options.pid) {
    process.kill(process.pid);
  }
}

//catches ctrl+c and stop.sh events
process.on('SIGINT', exitHandler.bind(null, {
  exit: true
}));

// catches "kill pid" (for example: nodemon restart)
process.on('SIGUSR1', exitHandler.bind(null, {
  pid: true
}));
process.on('SIGUSR2', exitHandler.bind(null, {
  pid: true
}));

//catches uncaught exceptions
process.on('uncaughtException', exitHandler.bind(null, {
  exit: true
}));

async function main() {
  try {
    var status;
    if (process.argv[2] === undefined) {
      bot_username = tokens.BOT_USERNAME.value;
      bot = new WickrIOBotAPI.WickrIOBot();
      status = await bot.start(bot_username)
    } else {
      bot = new WickrIOBotAPI.WickrIOBot();
      status = await bot.start(process.argv[2])
    }
    console.log(status)
    if (!status)
      exitHandler(null, {
        exit: true,
        reason: 'Client not able to start'
      });
    ///////////////////////
    //Start coding below
    ///////////////////////
    await bot.startListening(listen); //Passes a callback function that will receive incoming messages into the bot client
  } catch (err) {
    console.log(err);
  }
}


async function listen(message) {
  try {
    var parsedMessage = bot.parseMessage(message); //Parses an incoming message and returns and object with command, argument, vGroupID and Sender fields
    if (!parsedMessage) {
      return;
    }
    console.log('parsedMessage:', parsedMessage);
    var wickrUser;
    var command = parsedMessage.command;
    var message = parsedMessage.message;
    var argument = parsedMessage.argument;
    var userEmail = parsedMessage.userEmail;
    var vGroupID = parsedMessage.vgroupid;
    var convoType = parsedMessage.convoType;
    var personal_vGroupID = "";
    if (convoType === 'personal')
      personal_vGroupID = vGroupID;
    var found = bot.getUser(userEmail); //Check if a user exists in the database and get his position in the database
    if (!found) {
      wickrUser = new WickrUser(userEmail, {
        index: 0,
        personal_vGroupID: personal_vGroupID,
        command: "",
        argument: ""
      });
      var added = bot.addUser(wickrUser);
      console.log(added);
    }
    var user = bot.getUser(userEmail);
    user.token = "example_token_A1234";

    //how to determine the command a user sent and handling it
    if (command === '/help') {
      var reply = "What can I help you with?";
      var sMessage = WickrIOAPI.cmdSendRoomMessage(vGroupID, reply); //Respond back to the user or room with a message(using vGroupID)
      var users = [userEmail];
      var sMessage = WickrIOAPI.cmdSend1to1Message(users, reply); //Respond back to the user(using user wickrEmail)
      console.log(sMessage);
    }
  } catch (err) {
    console.log(err);
  }
}

main();
