Angular gives the freedom of creativity and uniqueness to developer’s work with Directives. Directives enable the developers to create custom HTML Tags and exploit them further to have access to behavior-driven elements. The easy manipulation of Dom attributes can be smoothly handled by Directives.
1. Component Development Kit( CDK )
Angular has never failed to amaze its developers with its amazing new set of features. The new upgrade has a Component Development Kit (CDK). It is CDK that makes Virtual scrolling and Refreshing go smoothly in Angular. Further, it also helps in Loading and Unloading the DOM that facilitates High performance.
1. Drag Drop Module
Angular helps to easily import the Scrolling Module or DragDrop Module. It helps In free Dragging, access to previews and placeholders. Another best feature it offers is the move item in Array and transfer array Item that make it create high-performance data lists.

moveItemInArray- is used for reordering the list

transferArrayItem- is used for transferring items between the lists

Conclusion

Angular is a super framework that has beautiful features to exhibit its importance. It provides zero loading time with promising efficiency. Forbes, BMW Find a Dealer, BMW Driveaway Price Calculator, and many other big Giants have their web presence in Angular js framework only. Angular is easy, efficient, and provides low code features. So if in doubt, choose Angular.

Sifars, a leading Angular Development Company, with its creative and experienced team, strives to provide its clients a modern, user-friendly website with its expertise. Further, we ensure the website to be robust, agile, and scalable to cater to a larger audience.

Best way to handle background processes in linux

Reading Time: < 1 minute
Every programmer soon comes to a point where he requires to setup several jobs to run in the background with 100% uptime. For example a website server, email server, job schedulers etc.

These processes are more like a daemon process. And as like any other job, these tend to stop due to mishandling or uncatchable exceptions/errors. Rather to put a person to sit and constantly monitor the jobs, we make use of the Supervisor.

A Supervisor is a process control system that will start, stop and monitor all our processes and will restart any, that fails.

To install Supervisor on Ubuntu:

sudo apt-get install supervisor

Configuring Supervisor

Let say we have a command that should run indefinitely:

python run_this_command

Supervisor configuration files are stored in the /etc/supervisor/conf.d directory. Let’s create a new configuration file as monitor-my-process.conf.

Inside monitor-my-process.conf write:

[program:my-worker] process_name=%(program_name)s_%(process_num)02d command=python run_this_command autostart=true autorestart=true user=linux_user numprocs=8 redirect_stderr=true stdout_logfile=/home/linux_user/app.com/worker.log

In this example, the numprocs directive will instruct Supervisor to run 8 processes of my command and monitor all of them, automatically restarting them if they fail. Also change the ‘linux_user’ to the user you want the process to be run as.

Starting Supervisor

Once the configuration file has been created, you may update the Supervisor configuration and start the processes using the following commands:

sudo supervisorctl reread sudo supervisorctl update sudo supervisorctl start my-worker:*

Cheers! Your processes will run indefinitely with auto restart.

Bonus!

Few more commands that are likely to be used sometime later:

Stop all supervisor workers:

sudo supervisorctl stop my-worker:*

Restart all supervisor workers:

sudo supervisorctl restart my-worker:*

Get the current status of workers:

sudo supervisorctl status my-worker:*

Vuejs: Constants from back end API
Reading Time: 2 minutes
Hardcoded values make a developer’s job hectic if these are repeated at several places in the codebase. That is why constants are an indispensable part of an application. It’s easy and intuitive to keep your application constants in a separate file and import them in other files to use.
```
import constants from 'path_to_file/constants.js'
```
But what when your constants reside on the backend and you need to get them by making an ajax request to the server. how would you make sure that these constants are available before any of your components get rendered? Should we write the received constants object into a file and then export it. It doesn’t sound like a real solution. Of course, it is not.

Object Prototype

So let’s approach it with a real-world solution. First, we need to understand function constructor and its prototype. In javascript, each object created using a function constructor has access to its prototype.
```
/** 
 * A function to create other objects. We captialize its name to distinguish 
 * it from other normal functions.
 */
function Person(firstname) {
  this.firstname = firstname;
}


// Add a property to its prototype
Person.prototype.printFirstName = function() {
  console.log(this.firstname);
}

// Create two different objects using the function as constructor
let person1 = new Person('Munish')
let person2 = new Person('John')
```
Since person1 and person2 are created using a function constructor so it has access to the printFirstName method.
```
person1.printFirstName()   // Munish
person2.printFirstName() // John
```
Vue Instance Prototype

We will use the same concept by fetching our constants object from backend and then putting it into Vue prototype. So that each component in our application has access to this property.
```
axios.get('http://SERVER_ADDRESS/getConstants')
.then(function(res) {

  Vue.prototype.$constants = res.body.data;
  // Initialize the main instance once you receive the constants from backend
  new Vue({
    el: '#app'
  })

});
```
Now you can access this constant object in any of your Vue components using the following syntax
```
this.$constants.someConstant
```
Note:

Make sure your getConstants API doesn’t do any heavy lifting other than returning your constants. Because the front end application will not get bootstrapped until it responds back.
