forte-lifecycle

Forte Lifecycle is expressjs middleware that provides lifecycle magic to your Forte experience apps.

Features

• Automatic Organization Resolver and Cache
  The first request processed will cause a forte-api call to be made that fills the organization cache. A request.organization prop will also be available for use in other areas of your express server.
• Automatic server.renderTime metric tracking
  All requests are timed and logged via node-statsd

Install

$ npm i -S forte-lifecycle

Quick Start

var express = require('express')
var forteApi = require('forte-api')
var lifecycle = require('forte-lifecycle')

var app = express()

var api = forteApi({...})

// register the middleware
// be sure to register the middleware before any routes that require trunk/branch scope info
app.use(lifecycle(api)) 

// now, all requests will have a request.lifecycle property
// and log server.renderTime using node-statsd
app.get('/', function (req, res) {
  res.send('Hello ' + req.lifecycle.scope.trunk '!');
});

app.listen(3000, function () {  
  console.log('Forte Experience app listening on port 3000!');
})
