Developing a progressive web application (PWA) is a complex process that consists of several stages and requires the participation of several dozens of specialists. Below we will review the process of developing such a product in a simplified version:
Planning and Analysis: defining the requirements and goals of the application, as well as market and competitor research. At this stage, the functionality and structure of the application are also determined. Specialists talk to the customer to take into account his wishes, after which they develop the terms of reference. Based on the TOR, all the next steps in the application development will be performed.
Design and interface: at this stage the design and user interface of the application are developed. The latter should be user-friendly and meet the goals and requirements of the application. The designer draws mockups of all screens, which is agreed upon with the customer.
Backend development and testing: at this stage, the server part of the application is created, which processes requests from the client and interacts with the database. Backend testing for functionality and security is also performed here. The backend is an important part: if there are bugs and errors here, the whole application will not work properly.
Frontend development and testing: at this stage the client part of the application is created, which displays the interface and interacts with the backend. Here testing is done for functionality, usability and design compliance.
Adding PWA functionality: in this phase, PWA functionality such as caching, etc. is added.
Performance Testing and Optimization: in this phase, performance testing and code optimization is done to make the application run fast and lag-free. The testers conduct manual and automated tests.
Deployment and publishing: at this stage, the application is ready to be deployed and published to the server. This is where the final testing is done and the server is configured to serve the users.
Maintaining and updating: once the application is published, you need to maintain and update it to keep it up-to-date and running smoothly.
Developing a progressive application is quite a complex task that requires taking into account a lot of information. Therefore, the creation of such a product should be entrusted to professionals.
