What is Heroku

What is Heroku?
Heroku (pronounced her-OH-koo) is a cloud application platform – a new way of building and deploying web apps.
Benefits of PAAS
Deployment using GIT
Tracking Your App in Git
$ git init
Create GIT remote
$ heroku create –stack cedar
$ heroku create –stack cedar –remote staging
$ heroku create –stack cedar –remote production
Creating falling-wind-1624… done, stack is cedar
http://falling-wind-1624.herokuapp.com/ | git@heroku.com:falling-wind-1624.git
Git remote heroku added
You can verify the remote in your git configuration as well:
$ git remote -v
heroku git@heroku.com:falling-wind-1624.git (fetch)
heroku git@heroku.com:falling-wind-1624.git (push)
Push Code to Heroku Remote
$ git push heroku master
$ git push staging master
$ git push production master
Stacks Available
A stack is a complete deployment environment including the base operating system, the language runtime and associated libraries. As a result, different stacks support different runtime environments.
$ heroku stack
Heroku aggregates three categories of logs for your app:
  • App logs – Output from your application. This will include logs generated from within your application, application server and libraries. (Filter: –source app)
  • System logs – Messages about actions taken by the Heroku platform infrastructure on behalf of your app, such as: restarting a crashed process, idling or unidling a web dyno, or serving an error page due to a problem in your app. (Filter: –source heroku)
  • API logs – Messages about administrative actions taken by you and other developers working on your app, such as: deploying new code, scaling the process formation, or toggling maintenance mode. (Filter: –source heroku –ps api)
  • $ heroku logs
  • $ heroku logs –source app –ps worker
Collabration
Adding Collabrator
$ heroku sharing:add joe@example.com
$ heroku info –app theirapp
$ git clone -o heroku git@heroku.com:theirapp.git
$ cd theirapp
You can now use git push heroku to deploy local changes and git pull heroku to merge any changes deployed by other collaborators.

Salesforce.com: Expression Operators in Salesforce lightning Components

Image
Generally In every component implementation we have a need to  change the UI conditionally, or show/hide a section/column based on certain conditions. We need simple ways to do this instead of having every handler in code. Below are key operators and their syntax to handle any such situation Ternary Operator This expression uses the ternary operator to conditionally output one of two values dependent on a condition. 1 <a class="{!v.location == '/active' ? 'selected' : ''}" href="#/active">Active</a> The {!v.location == ‘/active’ ? ‘selected’ : ”} expression conditionally sets the class attribute of an HTML <a> tag, by checking whether the location attribute is set to /active . If true, the expression sets class to selected . Using <aura:if> for Conditional Markup <aura:attribute name="edit" type="Boolean" default="true"/> <aura:if isTrue=&qu

A custom object with start dates and end dates for events 3.) Apex class to pull data from object and convert that into json using json.serailze First we have to upload the fullcalendar lib to static resource and then we have to create a visualforce page with below code. The important thing is "JSONOFLIST" which is just json created from list of records by using JSONOFLIST = JSON.serialize(LIST OF SOBJECT); It will give you a calendar with items highlited on page Source : http://www.saasanalogy.com/custom-calendar-on-visualforce-page/

Salesforce.com: Scheduled Apex

The Apex Scheduler lets you delay execution so that you can run Apex classes at a specified time. This is ideal for daily or weekly maintenance tasks using Batch Apex. To take advantage of the scheduler, write an Apex class that implements the Schedulable interface, and then schedule it for execution on a specific schedule. Scheduled Apex Syntax To invoke Apex classes to run at specific times, first implement the Schedulable interface for the class. Then, schedule an instance of the class to run at a specific time using the System.schedule method. global class SomeClass implements Schedulable { global void execute(SchedulableContext ctx) { // awesome code here } } The class implements the Schedulable interface and must implement the only method that this interface contains, which is the execute method. The parameter of this method is a SchedulableContext object. After a class has been scheduled, a CronTrigger object is created that represents the scheduled job. It p
