Introduction

Which is the best Backend technology for mobile app development?

You might want to find out which backend technology to use if you are developing a mobile app. The good news is that many choices function, but the trade-offs for each one must be known.

Consider the main elements: 

• a lot of bandwidth
• low latency
• frequent updates
• dynamic or static data
• simultaneous sharing, or other features

Here are some of the popular solutions.

Mobile App Backend - What is it?

You can see the Backend as a mobile app. But the Backend works usually on the front end; the backend works differently. It is a piece of software running on remote servers. The Internet is accessible via the API (app public interface). The backend is not intended for direct use by humans. But it is for other applications (frontend apps). It aims to carry out distant operations that cannot be carried out by the front-end Apps for some reason.

If it's not clear, it's okay. It should be easy to grasp the front-end app and then attempt to find out what it is to be more intuitive.

The best backend technology for mobile apps in 2021

Have your new startup a fantastic idea? First, let's get to know the most suitable backend technology.

Web programming languages Python, PHP, Ruby, and NodeJS, are the most used backend technologies. To achieve success, each must be matched with the appropriate: 

• frameworks
• libraries
• runtime environments

Our main backend technologies are PHP and NodeXS. But we do have systems in C#, Python, and Ruby that allow us to use different technologies.

Following are some of the most well-known backend development languages.

1. Java

Java is the most common language developers have used for programming for over 20 years. But, it is pretty adaptable and may be used from smartphones to intelligent cards.

It is popular with makers of desktop and commercial software. But, Python is less easy to start with because more code is needed to create features.

For (Android) Java backend technology can be used for the creation of: 

• mobile apps
• websites
• database connections
• image processing
• GUI-based programs
• networking, etc.

2. PHP with {insert-framework-name}

We use PHP to construct dynamic websites in a simple yet powerful language. It is a dynamically characterized language, ideal for beginners. You can use this language to: 

• collect data
• generate the dynamic content of your page
• send and receive cookies
• write the command line
• write desktop apps on your server

For minimal viable product development, the programming language used is PHP. It is possible to speed up the development process and create Microservices and Full-Fledged Web Apps. These apps can have several frames, such as Symfony, Laravel, Yii, or WordPress. Yes, it is a CMS but can also be used as a framework.

PHP can be used in three different ways:

• Script on the server: For dynamic web pages creation.
• Scripting command-line: The command line can run scripts (like a Unix shell).
• Scripts can be used for the management of system tasks. We can construct completely developed user interface apps by using tools like PHP-GTK (gtk.php.net).

On most OS systems, Unix to Windows and Mac OS X, PHP is available for use.

3. Javascript/NodeJS

JavaScript is the language for the programming of the frontend as well as the backend. For novices, it is a wonderful language as you can begin coding on your browser rapidly.

Along with HTML and CSS technologies, JavaScript lets you create dynamic web pages. We can change the content of the page using JavaScript according to the users on the site.

Anyone with past programming expertise can master JavaScript very fast. Particularly since the JavaScript language syntax is found in other popular languages. Such as C++, C#, Java, etc.

JavaScript can be used for the construction of many site kinds and software such as: 

• websites
• web servers
• mobile apps
• desktop apps
• games
• presentations, etc.

4. Node.js

Node is a fast and scalable apps platform. This backend framework may be used to make web apps or messages. It also allows cross-platform apps to be created. 

Node.js is part of a strong JS package. Hence, this framework allows you to construct both frontend and backend.

Backend technologies have also been added to their menus. This is done by adding NodeJS as a backend JavaScript implementation. NodeJS makes it easier to handle "parallel" requests because of its asynchromic core. It enables many requests to be handled while waiting for "slow" database answers.

For instance, by clicking a button, we can change the text in one paragraph. In addition, you may construct JavaScript storage variables to make the page more interesting. We may then forward an app to the NodeJS backend server. It will collect data from the database and allow us to alter the content of the live page without loading the page.

5. Kotlin

The programming language Kotlin is the most promising to learn. It is a popular programming solution for the Android assembly language. In the way that it codes your apps, Kotlin is efficient, easy to comprehend and learn. No wonder why both professional and amateur programmers adore it.

6. Python with Django

Python is the fastest-growing online and desktop programming language. Like Java, it is easy for those who begin. It is accessible. Its syntax is easy to understand. Especially compared to other backend languages for app development.

Python allows you to use several helpful frames, one of which is Django. This website improves the creation of software. It accelerates and makes it dependable and scalable. The Python and Django combo offers you many new software capabilities.

For Python, some of the most popular apps are: 

• simple Internet development
• multi-platform shell scripting
• fast automation are among

7. Ruby & Ruby on Rails

Ruby is a generic programming language that is object-oriented. The Japanese Yukihiro Matsumoto designed and developed it in the mid-1990s. Ruby allows developers to make their work more productive and more enjoyable.

Matsumoto was more attentive to the concepts of user interfaces when building Ruby and less to computer requirements.

Most programming languages are machine-oriented, offering different computer management options (memory, processor, etc.). The developer is Ruby-focused.

What happens to the memory exactly and how the processor is used does not matter.

The focus is that for everybody, whether Ruby is familiar or not, the program is reasonable. Ruby's just a fun language to program.

With Ruby, you can: 

• automate repeat jobs
• construct web apps, mobile apps, and games
• create prototypes

Ruby on Rails relies on the development paradigm of the "convention on configuration." Thus, it promotes lowering the number of decision-makers without compromising flexibility.

Thus, you can concentrate on your business logic and not worry about other aspects that are important for rapid iteration or prototyping.

8. C# and .NET

Simply put, C# is a language of programming, whereas NET is the structure for languages.

C# is a high-level, objective-oriented, developer-friendly programming language. It enables developers to design apps on their own and has the power of C++. But it is easier to use.

The .NET Framework is the technology to manage a common library of code. These codes can be used by developers, so they need not write code every time from scratch.

9. Express.js

Developers may opt for some alternative runtime, such as Express.js, with Node.js or Node.js plus. The app for Express.js will be running on a Node.js server in this example.

Now, Node is a server runtime for your code and assets to be installed. Or you can host the Node server with a container like Docker.

So when are you going to use Express in your web app? Express is best used on a web server Node. Here are some node apps you can construct with Express:

• Angular 2 - Express + Angular 2 + MongoDB + MySQL
• Rails - Express + Rails + Sinatra + MySQL
• Rocking Rails - Express + Rails + Ruby + MongoDB + MySQL
• Clojure - Express + Clojure + MongoDB + MySQL
• JavaScript + Rails + Express (Babel) + Model

Express.js is an all-around, full-stack web framework with great performance. You may also use Express.js to create premium apps. It gives more than a similar structure (for example, angular) and customer frameworks (such as Angular 2).

Express was developed as a web app construction tool. It was found useful by my teams for the development of: 

• APIs
• microservices
• modules
• key frameworks for apps

10. Spring.js

What Spring.js does so brilliantly is to connect your old app with new technology. In doing so, Spring can make it easier and more maintainable to extend the program.

This function might be as basic as injecting object instances in your classes or extending methods. This is useful since those object instances or processes are given excellent architecture. These objects describe the state of your app. You may plug into classes of user authentication, user interface, and other business logic to this app. This can be done by constructing an example Spring app that can be placed in a sandbox.

Spring.js is the smallest development group on this list in many respects. But, I added it since it is an excellent tool for spinning concept evidence (POC) and experimenting.

11. Back4app

It is a leading open-source supplier. It helps developers to construct scalable, extensive online and mobile apps at speed.

The solution is fully controlled and provides automatic scaling and parse-server apps. In addition, this method might enable you to personalize and optimize each app differently. Back4app is one of the preferred solutions for app creators with this distinctive functionality.

Some of its most important characteristics are:

• The REST and GraphQL APIs
• spreadsheet-like databases
• scalable hosting
• live questions
• push & email notifications

12. Firebase

Firebase is a toolkit to build, enhance and expand your app. The tools it gives developers include a huge number of services. These you have to create by yourself even if you don't want to.

Thus, Firebase is the solution if you focus on the app experience. The services covered by this framework include: 

• authentication
• analytics
• settings
• databases
• push messages
• file storage

With little work from the end of the developer, the services are held on the cloud and in scale.

Core Functionalities: 

• databases for NoSQL.
• APIs REST.
• Notifications.
• ML.
• Analytics.

13. Meteor

Meteor is used for mobile and online apps as a full-stack JavaScript framework. It was created in 2011 and has been a popular choice for developers. This is because it is ideal and one of the fastest prototyping alternatives. But, not long ago, developers knew Meteor was more than just a prototype.

They found it can be used for business development. Their flexibility in coding is due to the packages it gives. Meteor makes building web apps secure, robust, and easy in real-time. It is also responsible for everything from the browser app to the database or server.

Core characteristics:

• Reload live.
• Integration of databases. 
• Ecosystem.

14. Lavarel

Laravel is a fully functional backend framework for development. It enables engineers to make excellent apps based on PHP. Also, it simplifies and delivers excellent apps for challenging tasks like authentication and queuing.

The sleek and concise coding syntax allows developers to move their web development capabilities to the next stage. It is used quite successfully around the web. It has a migration mechanism for the database. It enables developers to design, edit and share the visual representation of an app database schema.

It is best for creating large to small online apps with extensive backend demands.

Main features: 

• Cache. 
• Modularity. 
• Authentication.

Architecture and Server- Working

Now, you may learn all the techniques of custom backend development and prepare for your next job as a developer. You must also chat with your team before beginning to work on your next appl project.

Backend development prepares your mobile app for its intended purpose. There are now notions to make it possible that has the server or the 'Software Stack' side of Backend.

Remember that the backend varies from app to app.

The distinction points can be measured by the use of: 

• data warehouses
• cloud-based servers
• containerized systems
• BaaS suppliers or APIs to substitute sophisticated operations

Allow me to take you back to the Backend mechanics with this out in the open.

Simplifying Down Backend's Software Stack

Allow me to simplify and divide the backend technology stack into its four components: 

• database
• server
• software
• operating systems

Here are the component details -

Servers

Whether it is in the cloud or on-site, the life vein of the network is a backend server for mobile apps. These offer resources that the networks must function as a mobile hosting platform. These common resources may include: 

• cryptography and security
• storage of files
• email
• database
• web services

Now, these servers are using virtualization to house several apps. Also, another term used for the servers is Containerization. The technique in which the server delivers segmented apps to the operating system.

Database

The database is what drives a website or app. Whenever a user requests from the appl, the database should accept the query. It then collects the information and sends it to the user of the app.

Besides providing information to a user, the database also accepts new data and edits the old data as desired by the user.

Middleware

Middleware is server software that connects the front end of the app. It permits client-server connection. It might be organized in many tiers – both in business and presentation.

It interacts with local apps and cloud apps. It offers features such as error management and data integration. Effective middleware can improve the administration of: 

• business processes
• user commitment
• authentication
• content management

These three are, first of all, the key components on which Backend Development is based.

Now, let me tell you about the finest mobile app backend technology used for large-scale projects of different sizes.

This is the list here.

1. Web server tools

• NGINX

This Open Source Software is used to serve the Web, cache, invert proxy, stream media, and load balance. This works as a load balancer and reverses proxy for TCP, UDP, and HTTP servers. It may also be used as an email proxy (POP3, IMAP, and SMTP).

• Apache

More than 50,1% of world apps use Apache, another open-source software. In the webserver sector, the mobile app hosting platform has shown its reliability.

2. Databases tool

• MySQL

MySQL is an open-source platform that is easy to install, scale, and free. We have placed our confidence in MySQL for all database requirements due to such factors.

• MongoDB

The utility saves all the information in binary JSON format. This makes it easy for data to move from server to client. The tool is also a NoSQL database system free open source.

3. Git clients

• SourceTree

The tool streamlines the interaction between developers and repositories Mercurial and Git. It makes repository management easier to enable individuals to concentrate on development.

• GitHub Client

The program employs HTML, CSS, and JavaScript to create cross-platform desktop apps. It provides developers with a 100% open source cross-platform experience.

4. Microservice platform-tools

• Kubernetes

The open-source platform used to administer the container cluster provides room for the scalability and automation of applicational containers across the cluster of servers.

• Docker 

Docker pictures Microsoft's services through its development services. It creates compartmental apps that are easy to use and are quick to package, deploy, and distribute. It also provides an ecosystem of tools such as registry, clustering, and cloud-based services.

5. Local development environment

• WampServer

It allows mobile app developing organizations to use the PHP, Apache, and MySQL databases for web apps. In addition, it comes as a package that supports the management of databases using SQLite and PhpMyAdmin.

• XAMPP

Apache Distribution includes the PHP, Perl, and MariaDB open-source Web server solution stack merged into a single file. The Apache distribution is included. In addition, the package of XAMPP has been created to make the configuration and easy usage.

6. Collaboration service tools

• Slack

The renowned cloud-based collaboration and message app have revolutionized company communication. Slack continues to make developers' life enjoyable and productive. This is because of its appealing UI and fast-growing user community.

• Jira

Scrum and Kanban are used for the administration of projects on the web. The tool was renowned for supply chain management in the 1980s by Toyota.

7. App performance test tool

• Apache JMeter

It can be loaded into the server with different settings to check the app's performance and speed. In former times, it was used for web app testing, but today is used for app performance testing.

• AppLoader

Another tool to test the app is to produce the very same user experience from all points of access. The tool allows you to test the entire business flow without adding a plugin or writing code.

Pros of Backend Development

The backend role in the app development service offers many pros in the development phases.

• Fast Development Speed.
• Efficient cost. Cost.
• Concentrate on key business.
• In less time, better production.
• Shrinking market time.
• Set of an enlarged app.
• Cloud infrastructure externalisation.
• Continuous integration.
• Security and performance.
• Data protection needs such as GDPR.

How can you select the best technology stack for a mobile app development project?

You can select to start working with many technology stacks. But, you must have a firm plan in place if you will pick the one that fits you best. This assures the app that you have developed is scalable, maintained, and secure.

It is important to focus on several vital issues that have a major influence on decision-making while building this plan.

Let's have a look

Requirements for apps.

Each app is in many different ways different from the others. Elements that distinguish one app from another include:

1. The app's devices to work on
2. the kind of network circumstances to operate
3. the user experience
4. the time on the market
5. the platform to operate on

The developer decides which frame, library, language, and software to use to achieve the best outcomes. They use all these elements and many else.

The app's objectives.

The purpose or end goal of the app is crucial when a developer chooses the technology to construct the app. But for rapid-response mobile app with minimal latency. The technology would vary when designing an app with a significant delay.

When the mobile app depends on heavy load processing. It needs to be more durable than the app that works with only streamlined interactions.

Skillset inside the company.

There are a few languages and frameworks which provide similar results. But which differ from one another in several typical factors. It is good to go with the developer's strengths when you decide between two technology stacks. These are rather close together.

If you finally push your development team to select a technology stack you don't know about. Then your efforts will go up, and the time it takes to construct it. If you offer them a technological pile that your team is experienced with. The speed of the procedure would not only be superior but also the quality.

The technology manufacturer.

In the creation of your mobile app, the parent company of your selected technology stack is vital.

Some of the more established businesses offer better documentation and support for the community. Google, Microsoft, and Adobe would, of course, provide far better support to the community. They also have advanced development options than React Native on Facebook.

Functioning on several platforms.

When you compare an app running on a single platform to an app running on all platforms. You will find that the stacks of technologies chosen to construct both are a world of difference. Also, the tools for scalability would be different for the Native App Development. Especially if ported to other platforms like the hybrid or Cross-Platform App Development.

Problems of security.

Every modern mobile app development technology is built to avoid any safety flaws that an app may encounter after its launch on the market. But, it is difficult to write long scripts that increase the hazards during the process. Especially if the technology stack you have chosen is not described right.

The expertise level of the developer is a key aspect. No matter how much technology you choose. The hackers would wound up any weak areas you could have left during the development process.

This is why your team of developers must also be skilled, together with the choice of the technology stack.

Technology compatibility you already use.

Choosing a technological stack compatible with the technologies you have is quite important. This is particularly critical if you want to introduce a new technology stack following the start of the process. Ensure that your selected technology stack is compatible with the current technology in the project. Also, compatibility between the Tech Stack and any other tools you plan to use later must be checked.

Conclusion

You may rely on different factors to choose background technology, such as: 

• product and service types
• their requirements for safety
• administrative concerns and advertising cut-offs
• products to competitors and developers' reasonability
