Development of applications for tracking the movement of goods

The growth of the online trading market has contributed to an increase in the requirements for express carriers – today the user wants not only to receive his package as quickly as possible, but also to be able to track its location at any time.

To meet customer needs and increase their competitiveness, many merchants and shipping companies are launching their own tracking services. However, in practice, this is not always convenient, since the buyer can place orders on different sites and use the delivery of several courier services, and monitoring each package in a separate application becomes inconvenient and time-consuming.

This situation has led to the emergence of more global tools on the market that provide the user with information about all his deliveries in a single interface.

For example, one of the most sought-after solutions in this industry is the AfterShip project, which monitors the movement of goods in more than 300 postal services around the world and provides effective tools for analysis and control.

Applications for cargo tracking can be developed to work on different platforms – in a browser, on a smartphone or on a personal computer. Accordingly, a different technological stack will be used to implement such solutions:

• Web applications. They work in the browser interface and do not depend on the operating system. The front-end part of such applications can be developed using static technologies such as HTML, CSS and JavaScript or reactive technologies such as Vue.js and React.js. In turn, the backend is created in PHP programming languages and its Yii2/Laravel frameworks, in Python and Django/Flask frameworks, or in Node.js.
• Desktop applications. Installed on a user’s laptop or computer. Their development is carried out using the Python and PHP programming languages, as well as their frameworks – Django / Flask and Yii2 / Laravel.

• Mobile applications. They are installed on a smartphone and work regardless of the browser and other applications. When implementing them, the operating system is taken into account: for development on IOS, the native Swift language can be used, and for Android, Java and Kotlin, respectively. However, there is an alternative, for example, using the Flutter framework and the Dart language, you can create cross-platform solutions that use the same code base to work on both operating systems, which can significantly reduce investment in production.

The choice of technology stack plays a fundamental role in the development of an application, because performance, development speed and scalability depend on it.

The process of creating an application can be compared to building a house: first, research is carried out, then the foundation is poured, load-bearing walls are erected, and so on – that is, all work is carried out in stages. If any step is missed, the final result will not be at all as planned. For example, it is difficult to imagine a house in which the roofing stage was missed, because it will simply be unsuitable for housing.

Let’s consider the main stages of creating a cargo tracking application, and what work is performed at each of them.

Stage 1. Information collection

First of all, developers need to define clear goals and objectives of the project. To do this, the Project Manager holds meetings or online meetings with the client, at which he records his requirements and wishes, and business analysts conduct a market analysis, which helps to determine the individual vector of development of the future application.

Stage 2. Design and preparation of technical documentation

After receiving all the necessary data, the developers begin to create a prototype – a schematic model of the future application, which will allow you to get a clear idea of ​​​​the capabilities and functional features of the project even before the start of its technical development. Most often, the prototype includes:

• Visualization of the project architecture and navigation system between its interfaces.
• Mockups of unique pages and screens, with a description of the functionality placed on them.
• Technological stack.
• Description of external services integrated into the project. For example, these can be postal service APIs, which will track the movement of goods in real time, banking interfaces for paying for subscriptions, etc.
• Implementation plan and planned development completion dates.

The created prototype will be used as a “foundation” for all subsequent stages of program production.

Stage 3. UI Design Development

A cargo tracking application is a project aimed at a wide range of users, so it is very important that it is convenient, attractive and intuitive for consumers from the first contact. To achieve this goal, professional UI designers are involved in the project, who shape the visual environment and feel of the project.

Stage 4. Creating the software part

Programming the program is a fairly general concept. If you delve a little into the processes, this stage can be divided into two key parts:

• Frontend development. It involves creating an interactive user interface in exact accordance with previously approved design layouts. In simple words, the frontend is a point of interaction between the user and the server – it receives requests from the client, sends them to the server, and then displays the processing result in a convenient format. However, there is a nuance here. If the frontend is developed using the reactive technologies Vue.js or React.js, which we mentioned above, in addition to the main task, it is also able to independently perform partial data processing, which reduces the load on the server. As a result, with this approach, the performance of the program and the speed of response to user actions increase significantly.
• Backend development. The backend is the server part of the program that processes client requests and is responsible for all processes that occur “inside” the program. When creating, programmers build the code architecture, organize the work of databases and integrate the project with external services using API or REST API interfaces.

Stage 5. Testing

Testing allows you to make sure that all the functions of the program work correctly and in accordance with the design. There are two main types of tests:

• Manual – carried out manually and are designed to identify non-obvious problems.
• Automated – performed using special computer scripts and allow tests to cover most of the project elements.

If errors are detected, the QA engineer writes a bug report and returns the project to the responsible specialist for revision, and after they are corrected, retests.

Stage 6. Technical support and development

Even with thorough testing, there are situations when, after starting to use the program in real conditions, users encounter problems that were not previously detected. In this case, developers study the error and quickly eliminate it within the framework of technical support.

In addition, during the first months after the release, it often becomes clear what functionality needs to be created or improved to increase the efficiency of the program. To solve such tasks, specialists draw up a new technical task, if necessary, refine design layouts, and then develop and implement the necessary changes. It is also worth adding that before installing an update to the original version of the program, it is pre-tested on a production server, which avoids unpredictable consequences.

The e-commerce market is constantly growing, and the number of local and international online orders is increasing accordingly. At the same time, users – including not only end consumers, but also retailers – need effective tools to track and manage shipments in real time. Thus, investments in the development of innovative solutions in this area will most likely become profitable and pay off.
