Web engineering

The World Wide web provides a wide range of complex enterprise applications that cover many different domain areas. Web applications are also unique to the Web application market and have specialized behavior and have unique challenges to be user friendly, performance, security, and ability to grow and evolve. Nevertheless, many of the apps are still being developed at a hot stage, causing a lot of us abilities, maintenance, quality, or reliability problems.

Merging proficient web engineering with an elevated level of technical expertise

Full-stack web engineers typically can create, develop and maintain features from idea to launch.

Web engineering is a term that describes the process of utilizing traditional software engineering practices [in an Open Web Application Security Project OWASP], methodologies, best practices, and tools when developing open web applications. An efficient development process needs to build upon skills that have been collected over time by the different members of the team. This enables quick learning about new team members joining in and guides less experienced developers in avoiding mistakes through lessons learned by more experienced people on the team. The result of this process should be a high standard code base with an established coding style, guidelines compliance, security audits, automated tests coverage, and so on.

Many open web engineers are familiar with the process of using internal resources, such as libraries or modules that simplify development tasks by abstracting out complex pieces of logic into reusable functions. The issue with this approach is that it breaks isolation - if an external library has a bug or becomes insecure, then all applications built upon that library can become vulnerable. This necessitates ongoing patching to maintain security but also causes an ongoing effort to be made to keep up with dependencies (e.g., keeping them up-to-date).

Decoupling code brings greater flexibility through increased modularity

A way to avoid these problems is to decouple our code from external open-source components by creating an abstraction layer between them which insulates the application against changes in other components. This allows us to update our code without having to worry about making changes across all applications that use it at once.

Web engineers typically use object-oriented programming (OOP) concepts like single responsibility, interface abstraction, dependency injection (DI), and encapsulation when creating web applications. This allows them to create an API that can act as the abstraction layer between modules or components of their application. The API needs to provide a boundary where code is isolated beyond this boundary it does not know the outside world. It also provides hooks for injecting dependencies (such as DAOs) into objects at runtime so that they are not coupled with concrete implementations during compile time. When developing APIs there are some standard methods for working with HTTP, however, to provide a flexible abstraction we cannot make use of these standard methods at all times.

Taking this principle further, the API should also expose only one entry point (one public endpoint) which is convenient for consumers but hides all internal implementation details from them. This provides developers the freedom to change the internal implementation whenever needed because it does not affect applications that depend upon it. By using this principle, open web engineers can evolve their APIs over time while maintaining backward compatibility making it easier to maintain and support existing projects that may still rely on older versions of an API.

This principle helps us prevent our components from becoming tightly coupled with every other component in the system. Any changes made to one part will not affect others which enhances stability and maintainability.

This principle helps us reduce the code duplication in the web application and make use of reusable modules instead. If we were to build each module from scratch, then that could result in a significant amount of duplicate code between modules; however, by decoupling our codebase into reusable modules/components we can avoid this problem and reduce maintenance efforts (since any changes made to existing components will not affect other parts).

This principle allows for increased portability since it enables moving pieces of functionality across different applications while avoiding conflicts between them. For example, if we have built a component that implements a specific algorithm - this same implementation can be reused by others without having to worry about version or conflict with another implementation found in different applications.

We discussed APIs and why they should be our primary concern when building a web application. An API acts as an abstraction layer between modules or parts of your application which can be upgraded without affecting the rest of the system. This helps you maintain backward compatibility while evolving APIs over time. We also went through some examples of how to properly utilize OOP concepts in a web application by applying the single responsibility principle, interface abstraction, dependency injection (DI), and encapsulation. Finally, we provided an example of how using these principles helps us decouple modules/components from other parts in a system allowing for increased stability and portability among them which ultimately improves maintainability.

Web engineering is all about creating powerful APIs to decouple modules in your application

When I'm building web projects the first thing I do is define my API contract and build upon it, exposing only one entry point (one public endpoint). My clients or consumers can access this one entry point which abstracts away all underlying implementations. This allows me to change internal features/implementations without having to worry about breaking existing applications -- because they are isolated beyond the boundary of my API.

Later on, when I need to add new functionalities not originally available in my initial release, I can simply do that by adding new modules that expose their APIs allowing other components in my system to access them while still maintaining backward compatibility (existing apps will continue using an older version of the API without any problems).

This design pattern is also known as Inversion of Control (IoC) and has been used in the .NET community for quite a while. IoC is achieved by creating a separate class/interface for each module or component that implements its functionality, then we inject this implementation into the main entry point which acts as an intermediary between our application logic and modules/components. We can also expose new interfaces if we need to add more functionalities without breaking the old ones. This is one of the most important architectural patterns that I use when building web applications.

What makes a good Web application?

A key criterion when developing a Web application is its appropriateness—the ability for it to perform exactly what was intended for it. To achieve this level of appropriateness, one must have a deep understanding of how users use their devices so they can take appropriate actions depending on their location, orientation, motion, data rate, etc.

The Web application is efficient in its use of the network, provides the most appropriate content for a specific device or situation, and offers feedback to the user about progress or lack thereof.

Functionality should also be considered when designing a Web application. The app should have exactly what users need to do their tasks successfully without any unnecessary bells and whistles that may cause errors within the system.

Security is another concern that must never be overlooked when developing a successful web-based application because the World Wide Web has become an open playing field with many different users across multiple networks who have varying access levels to information on it.

How do I become a web developer?

The web developer profile is based on the Internet world. Web developers are responsible for designing, creating, and implementing websites that are attractive to visitors. Web developers should have strong analytical skills and also be able to work well with other team members to address project objectives.

As a discipline

Web engineering increasingly draws on ideas from software engineering. It is expected that even more developers will be needed for this discipline, which generates challenges and opportunities. Web development requires the use of many programming languages (e.g., Perl, PHP, Python, Ruby), data storage technologies (e.g., SQL), web servers (Apache HTTP Server), and application servers (IBM WebSphere Application Server).

The emerging domain of web engineering focuses on challenges that are unique to Internet applications, such as scalability and accessibility while still working with existing standards such as HTML5, CSS, and HTTP. For example:

* Applications becoming unresponsive or unavailability due to spike in user requests * Applications where different data with different structures need to be displayed in the same view * Applications where different data with different structures need to be displayed in the same view

* Responsive design approach that enables a single application to adapt itself based on device, environment, or orientation in which it is being viewed

Web Engineering also focuses on the challenges of web applications' performance and availability, especially when working with large data volumes. Data mining can help discover new information from existing data. Web engineering stresses techniques such as caching, load balancing, and redundancy elimination for improving performance and scalability. Successful implementation of high traffic sites requires careful attention not only to algorithmic efficiency but also access patterns, machine characteristics (e.g., average access time), and cost of individual components (e.g., memory, bandwidth).

Types of projects in which web engineers can be involved include

Large information systems deployments * Support for modernization initiatives in large organizations * Large data-driven websites or portals driven by Big Data technologies such as Map-Reduce * Lightweight mobile environments where the emphasis is on high performance at low cost * Content management systems that manage large numbers of documents and images * Services to build web platforms that are self-managing, scalable, and robust.

As a domain of web engineering, Big Data collection and analysis has become an integral part of the data-driven aspect of Web engineering. In a world where data is the new gold, Big Data technologies such as MapReduce can help derive insights from large volumes of customer behavior data to understand customer preferences and predict future demand.

Web engineering is increasingly concerned with security models (e.g., authentication and authorization) to control user access to resources; network protocol implementations (e.g., HTTP, FTP), content management, and integration of existing application components (e.g., databases) with web-based applications through the use of web services (SOAP/RESTful).

What is a web engineer?

Web engineers are highly skilled software developers, with a responsibility to ensure that web applications consistently meet customer expectations for availability, security, speed of performance, and functionality. Typical responsibilities include

* Writing well-designed business logic that can be reused across many different use cases * Identifying bottlenecks in the application design and performing optimizations

* Participating in all phases of software development life cycle * Mentoring junior members of the team

Prerequisites include solid knowledge of object-oriented programming concepts (e.g., inheritance, polymorphism) and experience with at least one statically typed object-oriented languages such as C++ or Java. Familiarity with scripting languages such as PHP is also important to have an understanding of how web pages are generated on the fly.

Web engineers should know HTTP, HTML5, CSS3, and other web development-related standards to understand how a web application should properly behave on any device that requests it. Familiarity with Unix or Linux command lines is desirable as the majority of Web servers run on these platforms anyway. Experience with version control systems such as Git helps to manage code changes from multiple developers in a consistent manner.

As there are many layers involved in an enterprise-level web application, web engineers often work as part of a larger team where they will need to interact closely with software architects and product managers who specify use cases for the final delivery to the end customer.
