What is the backend of a mobile application
The backend is the internal “mechanism” that creates the logic of the application, processes user requests, and manages data. While the frontend is the client-side, the backend is the server-side of the client-server architecture. The backend ensures the functionality of the product, its interaction with external services, and the logical connection of all functions and data in the mobile app. Developing the backend is a mandatory step in creating most mobile applications that involve user interaction, database usage, and integration with other services.
Why is the backend important for mobile app users? Thanks to the backend, users can do more than just browse through the interface screens — they can perform targeted actions in the app, such as purchasing products, ordering services, searching, using navigation elements, logging in, making online payments, and much more. The user only sees the results of the backend’s work, which are displayed on the client-side, while the mechanics of these processes remain hidden in the server-side.
The main components of the mobile application backend are
The process of developing the backend of a mobile application includes several main components: server logic, working with databases, API integration, and creating an admin panel.
Server Logic
The backend processes commands received from the user in the application interface. The rules and algorithms by which the application processes user requests are determined by the server logic embedded in the backend. The server logic can be thought of as the “brain” of the application, processing commands and deciding how to execute them.
How does it work? The user presses a button – the backend sends a request to the server, the server part processes the information, checks the conditions for applying certain algorithms, accesses the database or integrated third-party services, and returns the answer to the application. This happens instantly – immediately after pressing the button, the user sees the result of the command on the screen. All the mechanics of user interaction with the application functionality is handled on the server side, so the speed, security, and stability of the mobile product depend on the quality of the backend development.
Databases
The information processed by the backend is securely stored in a database. The database contains all the data that forms the functionality and logic of the application — for example, saved settings, pricing information, discounts, product availability, user action history, account data, authentication data, and much more. The backend accesses the database to retrieve or compare information, check the conditions for executing commands on the server side, and make decisions about further actions. We develop the backend using two main types of databases depending on the application’s functionality and the complexity of user scenarios:
- MongoDB – a document-oriented NoSQL database for working with unstructured data, allowing handling large volumes of information with efficient scalability.
- PostgreSQL – an object-relational database for working with large structured datasets, ensuring efficient operation of large-scale applications with complex functionality.
API Integrations
API (Application Programming Interface) is used for integrating the mobile application with third-party services. It is a set of instructions that ensures interaction between the client-side and server-side of the product. Common examples of services that can be integrated with mobile apps include:
- payment systems for secure online transactions;
- Google Maps for route planning;
- company websites for synchronous order processing;
- social networks for login via existing profiles;
- analytics systems for collecting data on app performance;
- CRM and other business automation programs used by the company.
Integrations with third-party services via API expand the functionality of the app, create convenient conditions for users, and provide the company with more tools to solve business tasks – increasing sales, attracting customers, and strengthening audience trust.
Admin Panel
The backend processes data and organizes the logic of the application – for more flexible configuration of these processes, an admin panel is created. The admin panel has a separate interface designed for administrators. They have the ability to:
- manage content – delete, edit, publish;
- set access levels for other administrators;
- adjust functionality, some API integration parameters;
- process user requests;
- receive statistical data on the app’s performance;
- work with the user database and their activity history in the app.
An administrator without programming skills can independently, without contacting the developer, partially adjust the application’s functionality, influence its operation, and change settings. This provides certain flexibility in managing the backend and makes the daily maintenance tasks of the app easier.
Benefits of custom backend mobile application development
Stages of back-end mobile application development
We analyze the client's tasks, estimate the project budget, determine the optimal functionality and practical implementation strategy. We formulate a technical task that includes a list of functions, application logic, structure, navigation, and user scenarios.
We create a detailed plan for the practical implementation of the project and the development of the backend of the application. We select database types, design the architecture, define the backend structure, interaction logic between application components, caching mechanisms, API integration methods, security parameters, etc.
We choose a stack of technologies - frameworks, programming languages, databases and other backend development tools. In our projects we use PostgreSQL and MongoDB databases, React JS library (Next/SSR), TypeScript programming language, React Native framework, Node.js platform (Express/Nest).
We move on to the practical implementation of the functionality, developing the backend logic, API for the interaction of the server side with the interface. We set up integration of the application with external services. We create an admin panel for managing the application settings and content.
We test the developed product, verify the speed of the application and correctness of API integrations, identify bugs and fix errors. We take measures to optimize the performance and security of the mobile application. We prepare the product for moderation in Google Play and App Store.
Супроводжуємо проект після запуску, моніторимо роботу бекенду, усуваємо помилки, запускаємо оновлення. Підтримуємо злагоджену роботу додатка та адмін-панелі. Якщо проект активно розвивається, проводимо роботи з розширення функціоналу та масштабування застосунку.
APPLICATION DEVELOPMENT TECHNOLOGIES
How much does backend mobile application development cost?
The cost of developing a backend mobile application is calculated individually for each project and depends on several factors.
Complexity of Logic and Functionality
The price is influenced by the functionality, logic, architecture of the mobile application and the need to develop an admin panel.
Technologies
The technology stack affects the level of specialists involved in the project and the labor costs for its practical implementation.
API Integration
The cost of the backend depends on the amount of integration of the application with third party services - payment instruments, cards, website, CRM and others.
Technical Support
The project budget may include the cost of technical support services, release of updates, and backend scaling.
