By TCell.

TCell Hooks is to be used in conjuction with the tcell_agent to allow for custom event notifications of login failures and login successes.

Getting started

You can manually add it to your package.json file or install and save it with the following command:

npm install tcell-hooks --save

There are several options for calling the hooks from your application code:

• Providing an Express request object and having the TCell Agent extract the relevant details from it:

  var TCellHooks = require('tcell-hooks').v1;
  
  // successful login
  var username = 'some-user-id',
      sessionId = req.sessionID,
      password = 'some-password'
  TCellHooks.sendExpressLoginEventSuccess(req, username, sessionId, password);
  
  // failed login
  var username = 'some-user-id',
      sessionId = req.sessionID,
      userValid = false,
      password = 'some-password'
  TCellHooks.sendExpressLoginEventFailure(req, username, sessionId, userValid, password);

• Providing a Hapi request object and having the TCell Agent extract the relevant details from it:

  var TCellHooks = require('tcell-hooks').v1;
  
  // successful login
  var username = 'some-user-id',
      sessionId = 'session-id'
      password = 'some-password'
  TCellHooks.sendHapiLoginEventSuccess(req, username, sessionId, password);
  
  // failed login
  var username = 'some-user-id',
      sessionId = 'session-id'
      userValid = false,
      password = 'some-password'
  TCellHooks.sendHapiLoginEventFailure(req, username, sessionId, userValid, password);

• Providing each individual piece of information required for the TCell event:

  var TCellHooks = require('tcell-hooks').v1;
  
  // successful login
  // NOTE: this is how you would obtain this info from an ExpressJS request.
  //       Obtaining this info in a different framework will likely differ
  var username = 'some-user-id',
      sessionId = req.sessionID,
      userAgent = req.get('User-Agent'),
      referrer = req.get('Referrer'),
      remoteAddress = req.headers['x-forwarded-for'] || req.connection.remoteAddress,
      headerKeys = Object.keys(req.headers),
      documentUri = req.protocol + '://' + req.get('Host') + req.originalUrl,
      password = 'some-password'
  TCellHooks.sendLoginEventSuccess(
    username,
    sessionId,
    userAgent,
    referrer,
    remoteAddress,
    headerKeys,
    documentUri,
    password);
  
  // failed login
  // NOTE: this is how you would obtain this info from an ExpressJS request.
  //       Obtaining this info in a different framework will likely differ
  var username = 'some-user-id',
      sessionId = req.sessionID,
      userAgent = req.get('User-Agent'),
      referrer = req.get('Referrer'),
      remoteAddress = req.headers['x-forwarded-for'] || req.connection.remoteAddress,
      headerKeys = Object.keys(req.headers),
      documentUri = req.protocol + '://' + req.get('Host') + req.originalUrl,
      userValid = false,
      password = 'some-password'
  TCellHooks.sendLoginEventFailure(
    username,
    sessionId,
    userAgent,
    referrer,
    remoteAddress,
    headerKeys,
    documentUri,
    userValid,
    password);

Important Note

If the tcell_agent is not installed or if it's disabled, this code will do nothing and should have no performance effect on your app.
