Progressive Web applications (Progressive Web Apps)

Recently, we have heard about the applications of the Progressive Web Apps (Progressive Web Apps) and their shortening is the PWA. These applications are Internet applications, which are used on the main screen of all mobile phones, and we will discuss in detail the applications of the Advanced Web on the website [ Ingeshop] (https://trinavo.com/).

Progressive Web applications (Progressive Web Apps)

1. [hyper application] (https://ar.wikipedia.org/wiki/%D8%AA%D8%B7%D8%A8%8A%8%D9%82 %D9%88%D9%8A%D8%D8%A8 %D8%A%D8%A%D9%82%D8%D8%D9%85%D9%D9%8A) or SPT.
2. Rather, it is a set of good practices and features that must be available in the application of the web to be similar to the original mobile applications we used to download from the Play Telephone android and the Apple Telephone and Applied Platform.
3. The objective is to give users of web applications a similar experience to the original application experience.
4. This type of application is supposed to work well in all devices, with all its advantages and technical potential.
5. For example, some features and functions may not be available in some old phones or devices.
6. But it must be ascertained that the application continues to work well, especially in terms of performance and speed.

When do we say the web application is progressive?

As we said at the outset, PWAs are just applications made up of CSS, HTML and JavaScript, and, of course, work in the canteens, but what distinguishes them from others is a set of advantages and points that we collectively find only in a few web applications, and we will not be able to establish a progressive application and a forward-looking Web unless we are fully aware of these points or principles.

Safe PWA applications

PWAs work with a number of original reviewer interfaces, which operate only on pages and sites provided through the https Protocol to protect users from man-in-the-middle attacks targeting their sensitive data. In general, the use of the HTTPS Protocol has become strongly recommended by each Web site owner, and even Google has decided since its adoption as one of the criteria for the classification of research results.

" Respondent Advanced Web applications

The phased application of the Web must respond to all types and forms of appliances, and the user interface must be easy and accessible to users regardless of the size of the screen they open to.

#" Applied even if there's no Internet connection

1. In the original mobile applications, we can open the application and see the main parts of the user interface (for example, top tape) even if the device is not connected to the Internet. No doubt you tried before entering Facebook or Twitter without contact. However, I noted that the application presented the old content stored in the temporary storage memory.
2. This experience is what progressive web applications seek to simulate, and the means to do so are known as service workers.
3. In short, service workers are a symbol or a text programme operated by the rear browler and separated from the web page (not able to reach DOM).
4. This advantage is used in progressive Web applications functions that do not require direct interaction with users.

The main objective of establishing advanced Web applications is to enable users to open them from the main screen of the telephone, as they do with local applications, to reach this goal, you must add Web Manifest to the application, a JSON file containing a set of application information such as code, name and screen direction.

• These applications are supposed to be very fast, especially during the downloading. According to Google, about 53% of users close any Web site that takes over 3 seconds. Speed and motionfulness in application must be a major objective and major concern during the construction of modern Web applications. By improving the speed of downloading only, companies and major locations have been able to increase the number of meetings per visitor, which means reducing the rate of return of visitors.
• Thus, the conversion rate has been raised at rates that in many cases have reached 10% to 15%.
• This job isn't easy, especially if the application is big.
• A number of techniques such as Webpack must be used to divide the source code upon request or what is known to divide the code.
• The Google model of PRPL has been formulated as a road map for building high-performance applications.

" PWA applications every page has a special connection

1. Each page in PWA must have its own connection so that search engines can fully as well as with other Web applications.
2. Also so that the user can share those pages on social communication platforms.
3. When establishing a single-page application, it must be ascertained that the guidance system creates the status of the starting page based on the address given to it by URL.
4. As I mentioned earlier, access to this advantage has become easier by Java frameworks. modern Script.
