How to choose your tech stack?

Before you start developing an IT product, you have to make many decisions that will significantly impact the future of the project.

Choosing the right technology stack can affect development time, cost, application quality, and scalability, so making the right decision is essential.

In this article, we want to explain the technology stack of a mobile application, consider the available technologies, their pros and cons, and choose which technology is suitable for a particular case. Besides, we have selected several essential factors to consider before deciding on a technology stack.

What is a tech stack?

A technical stack is a set of tools used in projects and includes programming languages, frameworks, database management systems, compilers, etc.

Work performance, hardware resource requirements, and software reliability depend on the developer’s technology stack. As a result, it determines how financially affordable it will be to deploy the system and operate it and how much it will meet the customer’s requirements for complex processes and high-load systems.

How to choose a technology stack for a project?

At this stage, we would like to identify the main factors when deciding on the technical stack of mobile applications.

App size

It is necessary to consider the project’s size and purpose when forming a tech stack since they significantly affect the technologies’ choice. Then the project is larger, the bigger and more complex the stack will be.

For example, for small projects (MVP or single-page apps), well-established stacks like Python-Django or Node.js-React might be ideal.

Medium-sized projects such as online shopping and midsize business apps require slightly more complex tech stacks with multiple levels of programming languages ​​and frameworks.

Large projects, such as complex marketplaces or enterprise apps, require a large-scale stack to maintain its integrity and performance. Such large tech stacks typically use multiple levels of programming languages ​​and frameworks. They are designed and used to work in a data-heavy environment.

It is important to remember that you should not burden the project with other technologies. There should be exactly as many of them as is necessary for the practical solution of the task.

Experience and resources

It is necessary for a competent selection of technologies to have good technical and architectural experience and knowledge.

It is worth giving preference to a company that has expertise in your industry. Do not select a team that has not previously worked with the chosen technology. It can lead project developers to sit around and take apart new technology instead of effectively moving forward.

Template solutions or outdated technologies lead to difficulties with project support and efficiency.

Also, it is worth considering the availability of resources for the implementation of the project. You should consider your budget and time, as well as the number of developers working with the selected technology.

Development time

The speed of project development is one of the most critical factors. If the project were developed quickly, the best option would be to choose ready-made solutions. Stack providing easy integration. These combinations of technologies reduce overall development time through third-party integrations.

Security

In 2021, a mobile application must be secure. The number of cyberattacks continues to grow. You need to take it seriously to take care of the security of your data.

Any user wants to be sure that his data is safe. Therefore, when forming a stack, it is necessary to choose technologies that provide a high-security level. This problem is significant, especially when it comes to online payments.

The cost

For many companies, this is one of the most critical factors. Most frameworks and tools are free and open-source. Still, you need to calculate the number of developers to complete an application in a given period using your chosen technology.

You also need to factor in maintenance and server costs. If you want to reduce maintenance costs, it is worth considering a serverless architecture for your application.

Scalability

The app architecture must be scalable and maintainable. Therefore, you need to choose a good project structure and take care of using reliable technologies.

Scalability determines whether your application can handle the load. For example, if the number of users increases, your technology stack must allow your application to drive this growth.

There are two types of scalability - horizontal and vertical. The first means the ability to work on different devices and cope with the increasing number of users. Vertical scalability means the ability to add new features or elements to your application in the future.

To achieve good scalability, it is better to use powerful programming languages with various libraries and structures in their arsenal.

Serviceability

Serviceability is one of the main factors when building applications. Maintaining your application should be effortless, even when scaling.

In particular, two factors affect the serviceability of your application:

  1. architecture: should support reusability, be mobile and scalable;

  2. codebase: should not be too long or too short, as long code takes longer to process, and compressed code can lead to errors during debugging.

Technology stack for iOS apps

We have prepared the most common list of technologies for iOS apps:

  1. Programming languages: Objective-C or Swift. Objective-C is a proven compiled object-oriented programming language. However, the future belongs to Swift, as it is more functional. There are fewer bugs when writing Swift code. It also contains dynamic link libraries that are loaded directly into memory, reducing the application’s original size and improving its performance.

  2. IDE: Apple Xcode. If you prefer Swift, then you cannot do without an integrated development environment. Apple Xcode lets you build both mobile and desktop apps. Xcode supports Git repositories and has a built-in graphical editor for quick interface design. An auto-debugger is also integrated into the IDE.

  3. SDK: iOS SDK. It is an application programming interface (API) that serves as a link between software applications and the platform on which they run. The iPhone SDK includes the following kits: Cocoa Touch (responsible for the touchpad, control, and camera), Multimedia, Service Core, and OS X Kernel.

Technology stack for Android apps

For Android development, we most often use the following technology stack:

  1. Programming languages: Java or Kotlin. Java is a proven, authoritative language with extensive tooling and many open source libraries. Kotlin is a more stable and consistent option. Its syntax is much lighter and cleaner. If several programmers work on creating an application, it will be easier for them to finish each other's tasks.

  2. IDE: Android Studio and Android Developer Tools. Kotlin is paired with an IDE. With Android Studio, you can edit code, debug. It has productivity toolkits that provide a flexible build system and an instant build/deploy system. Using Android Studio allows you to focus on building cool apps instead of wasting time on tedious processes. Android Developer Tools makes coding easy. It includes various debugging tools, a GUI builder, emulators, and automated testing support.

  3. SDK: Android SDK. To write programs with the latest features, developers must download and install SDK versions for each smartphone model. You can download the official and third-party components of the Android SDK separately.

Conclusion

Choosing the right tech stack is essential to the application you plan to build and smoothly complete the development process to the deadline.

To make the right choice among all the technologies available on the market, you must carefully study the application’s essential features and look at the factors influencing the decision.

At the stage of planning and choosing a technology stack, it is best to turn to professionals. You must be sure that the selected technologies are suitable for your mobile application’s specifics and will allow you to implement all the features.
