NODE JS VS PHP: WHICH IS BETTER?

October 20, 2020 Connexis Technologies

Both NodeJS and PHP are two of the most widely used server-side technologies. Nonetheless, there are a lot of differences between the two leading backend technologies. While PHP is a programming language, NodeJS is a cross-platform JavaScript runtime environment.

Before moving on to the differences between NodeJS and PHP, let us first take a brief look at both the technologies.

PHP

Created by Rasmus Lerdorf, PHP made its debut sometime in 1995. Originally, PHP meant Personal Home Page but now it is a recursive backronym for PHP: Hypertext Preprocessor. The open-source, server-side scripting language is developed specifically for web development.

Unlike other popular programming languages, PHP evolved without a written formal specification up until 2014. The original implementation of the programming language acted as the de facto standard up until that point.

Though PHP is a server-side scripting language, it can also be used for other purposes. PHP scripts has a .php extension and contains a combination of CSS, HTML, JavaScript, and even plain text. As of now, PHP is one of the leading programming languages to get a job.
Facebook, Flickr, Wikipedia, Yahoo, and Tumblr are some of the leading names that have been built using the PHP programming language.

Node Js

Node.js was created by Ryan Dahl in 2009 which enabled building backend application with javascript rather than using the traditional technologies – PHP, C#, Python or PERL. This made it possible to build an application with a single language across the stack. Node.js is built on Chrome’s V8 JavaScript engine and known for being asynchronous, event-driven and nonblocking.

PHP vs NodeJS

To make the comparison between PHP and NodeJS easy to understand, we have divided the complete section into various categories:

Program Type (Synchronous and Asynchronous)

One of the key differences that separates the PHP and Node.js is the way they execute the codes.

PHP has been known for the synchronous execution of codes. As per the term suggests this backend language executes the codes in sequence (synchronization), so it doesn’t matter how long a function takes to execute, it won’t move to the next one until it’s completed.

Database Preference

More often than not, PHP is used with traditional or relational databases to the likes of MariaDB, MySQL, and PostgreSQL. Though there are ways to use NoSQL databases with PHP, doing so is not so frequent in the industry.

Though NodeJS works fine with SQL databases, the trend is shifting towards using NoSQL databases, such as CouchDB and MongoDB.

Frameworks

Frameworks have made life easier by speeding up the development process and helping developers to write structured, reusable and maintainable codes. So, while considering between PHP vs Node.js, frameworks play an important role.

When it comes to PHP, there is a huge list of frameworks at your disposal. Just name it – Laravel, Codeigniter, Symphony, CakePHP, FuelPHP, Phalcon and the list goes on.

When it comes to Node.js, we see a growing number of frameworks along with its growing community. Although you may not get the options as varied as PHP, some of the well-known frameworks are – Express, Meteor.js, DerbyJS and Sails.js.

Development Stacks

While writing back-end code in PHP, the developer frequently switches between different programming languages. This is due to the fact that PHP is mostly used as a part of the LAMP (Linux, Apache HTTP Server, MySQL, and PHP) stack.

NodeJS, on the other hand, typically uses either MEAN (MongoDB, Express.js, AngularJS, and NodeJS) or MERN (MongoDB, Express.js, React, and Node.js) stack. The only programming language knowledge required for using the entire stack is JavaScript.

Webserver Setup

PHP versions prior to v5.4 required downloading and setting up LAMP and XAMPP servers. However post that, PHP comes bundled with an inbuilt development server.

NodeJS, on the other side, comes prepackaged with core modules, including the file system, HTTP, and DNS. These help in developing customized web servers.

Build An Ios Application That Interfaces To IoT Device Using Bluetooth

October 8, 2020 Connexis Technologies

Manufacturers and industrialists in every sector have a significant opportunity at hand where they can not only monitor but also automate many of the complex processes involved in manufacturing. While there have been systems that can track progress in the plant but the industrial IoT (IIoT) technology provides far more intricate details to the managers.

IoT

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

Why IoT is important

The internet of things helps people live and work smarter as well as gain complete control over their lives. In addition to offering smart devices to automate homes, IoT is essential to business. IoT provides businesses with a real-time look into how their companies’ systems really work, delivering insights into everything from the performance of machines to supply chain and logistics operations.

IoT enables companies to automate processes and reduce labor costs. It also cuts down on waste and improves service delivery, making it less expensive to manufacture and deliver goods as well as offering transparency into customer transactions.

Arduino Overview

We know how to send or receive data over the internet from an iOS app. But many of us don’t know how this data operate the IoT devices. There are open-source hardware and software available in the market which is used to control the IoT devices. One of these is Arduino.

Arduino is an open-source hardware and software. Arduino boards are able to read inputs from the different sensors and turn it into an output like turning on an LED, activating a motor or publishing it over the internet.

These boards can take the following inputs and outputs:

Inputs:

Temperature, Humidity, Pressure etc
Light, Infrared signals
Sounds
Motion captures
Heart rate, muscle movement
Electrical current
Touch, Fingerprints

Outputs:

LEDs
LCDs
Speakers
Motors
The internet

There are different types of Arduino boards available depending on features like an ethernet port, wireless or USB device support. Common specification of these hardware boards are:

ATmega 328 8bit chip
5-20V power supply
32 KB flash memory
20 I/O pins

You can tell Arduino boards what to do by sending a set of instructions to the microcontroller on the board. For this, we have to use Arduino Software (IDE) and the Arduino programming language.

Arduino IDE:

To write code and upload it to the board, Arduino IDE is used. It is available for Mac, Windows, and Linux platforms. You can download it Here.

Arduino programming language:

The coding language that Arduino uses is very much like C++, which is a common language in the world of computing.
Two important functions in Arduino language are:

setup( ) – Every program should have this function. This runs once at the start of the program like the main () function. You can do initialization stuff in this function.
loop( ) – Every program should have this function. This gets called repeatedly. You can use it to actively control the Arduino board.

Other Useful Function:

pinMode() – Set a pin as input or output
digitalWrite() – Set a digital pin high/low
digitalRead() – Read a digital pin’s state
analogRead() – Read an analog pin
analogWrite() – Write an analog value
delay() – Wait an amount of time

Example Code:

int ledPin = 3;
// setup initializes serial and the LED pin
void setup(){
Serial.begin(9600);
pinMode(ledPin, INPUT);
}
// loop checks the LED pin state each time and broadcast it whether it is high or
// low
void loop(){
if (digitalRead(ledPin) == HIGH)
Serial.write(‘H’);
else
Serial.write(‘L’);
delay(1000);
}

You will find more details about the language at https://www.arduino.cc/reference/en/.

Once you write the code, you can upload it to the Arduino board by using Arduino IDE. You can download a demo Arduino program to turn LED on-off. This program sends/receives data over the Bluetooth and turns on-board LED on-off depending on the data received. Also, this will broadcast the state of the LED pin. You can use the Arduino Leonardo board for this demo.

You can modify this demo program for the internet instead of Bluetooth. For an internet network, an Arduino board which has the capability of broadcasting data over the internet is required.

Uniqueness

Every business is interesting. There’s nobody size-fits-all solution to the extent business processes are concerned. Having a software customized to suit your one of a kind prerequisites can supplement your working model. Custom software development additionally supports your “one of a kind” character in the market.

Cost-effective

Developing custom software might be costly now and again, however they demonstrate advantageous over the long haul. Custom software does not require consistent change or development to suit company prerequisites. They can be utilized with no investment for quite a while.

Secure

Softwares that get hacked usually are the well-known ones in the market. Hackers and attackers are as of now mindful of the vulnerabilities of such software and realize where to settle. A custom-developed software is just utilized by your team and odds of interruption are limited.

Flexible

Custom software can be scaled by the changing needs of the company. An off-the-rack application can’t be controlled voluntarily and stays consistent in its contributions. It either turns out to be excessively costly or inadmissible to continue utilizing them.

Optimized business process

Every organization has its very own business model and in-house processes. It is extremely hard for organizations to change their processes to suit a specific software bundle or application, anyway productive and incredible it might be. In this way, software should be structured and developed in a way to such an extent that it can line up with the business model and pursue the organization’s one of a kind in-house processes. Custom software development streamlines your business processes instead of supplanting them.

Invention

Since the software is completely customized, you have the alternative to choose what sort of software development innovation to use to structure your own app. You have the ability to choose and pick pattern setting troublesome advances to plan your customized app and make it work the manner in which you need it to.

Reliability

The capacity to upkeep and pursue your business processes after some time encourages you to succeed in the end. Reliability is the main consideration that characterizes achievement. Appropriate testing of your custom software guarantees you have a solid IT apparatus that can develop your business.

Software that is developed solely for you guarantees that the majority of your exercises and processes are appropriately routed to and mechanized precisely according to your necessities.

Compatible

An organization utilizes much software for its activity. Custom structure software considers and develops it to be compatible with other company tools. General software ordinarily causes integration issues that are not there in the custom-developed software.

Scalability

Businesses continually develop; that is the general purpose of beginning them in any case. Off-the-rack software will be unable to deal with the overwhelming burden while custom software is developed in view of the considerable number of changes. Custom software develops as the company develops.

Support

With custom software, you likewise get a reliable technical support team that was engaged with the development process of your application. They know about your software and can deal with any issues that emerge en route.

These software components have been arranged in 4 categories in which one of the categories is Architecture Components. Other categories are Foundation Components, Behavior Components and UI Components.

Android architecture components are a collection of libraries that help us in:

Building a robust Android application.
Building the testable Android application.
Building the maintainable Android Apps.

Android architecture components help in managing our UI component lifecycle and handling data persistence.

The Android Architecture Components are as follows:

Data Binding: It helps in declaratively binding UI elements in our layout to data sources of our app.

Lifecycles: It manages activity and fragment lifecycles of our app, survives configuration changes, avoids memory leaks and easily loads data into our UI.

LiveData: It notifies views of any database changes. Use LiveData to build data objects that notify views when the underlying database changes.

Navigation: It handles everything needed for in-app navigation in Android application.

Paging Library: It helps in gradually loading information on demand from our data source.

Room: It is an SQLite object mapping library. Use it to Avoid boilerplate code and easily convert SQLite table data to Java objects. The room provides compile-time checks of SQLite statements and can return RxJava, Flowable, and LiveData observables.

ViewModel: It manages UI-related data in a lifecycle conscious way. It stores UI-related data that isn’t destroyed on app rotations.

WorkManager: It manages every background jobs in Android with the circumstances we choose.

There is a whole new set of components out there, start experimenting and using classes in your apps.
