Comprehensive Study

The biome of JavaScript is constantly evolving and a new framework or library is launched on a regular basis claiming better features. This study focuses on giving guideline to the reader in the process of choosing the best technology by comparing the runtime performance of the MERN (MongoDB, Express, React.js and Node.js) and MEVN (V stands for Vue.js) stack as well as increasing their workability in the job market. To fulfill the purpose, an experiment was conducted to conclude how swift the said stacks perform in building a single page application. For the experiment, two easy to-do applications are built with MERN and MEVN and loading time, adding time, updating and deleting time of the tasks are measured. Moreover, to be able to reveal the software stack trend among the Swedish-based companies, a survey study was conducted. Out of approximately 70 companies contacted, 12 responded. Due to the low number of response on the survey drawing conclusions from the survey and generalizing, the result was challenging. However, the results gathered show that all the respondents use either Vue.js or React.js or both as their client-side software though they are not always combined with Node.js and MongoDB. Other preferred server-side software that are used in combination with React.js or Vue.js are Java, Go and Django. Some of the main factors that the respondents pointed out that affects their choice of software was the ease of learning, the community behind the software, clients’ need and availability of that specific software developer.

Core Part

Short for Browser/Server, B/S is designed to centralize the core part of system functions on the server side, when users just need to install a browser on the client side, such as Internet Explorer, Firefox. Thus, the browser can be used for data exchange through the Web Server anywhere, as long as the computer accesses to the Internet. As a result, there is no doubt that the development of B/S structure system has become main-stream as the Internet has developed rapidly today [1]. As we all know, it is increasingly challenging that customers are having more and more requirements of details and depths, which demands more of a software developer. Now we are exploring a new method of programming by configuring database in order to improve the traditional three layer architecture (3-tier application). It would be quicker and more convenient for developers to modify functions according to the requirement changes from customers, largely reducing the workload either in development or maintenance.

The approach to organizing the automated calculations’ execution process using the web services (in particular, REST-services) is reviewed. The given solution will simplify the procedure of introduction of the new functionality in applied systems built according to the service-oriented architecture and microservice architecture principles. The main idea of the proposed solution is in maximum division of the server-side logic development and the client-side logic, when clients are used to set the abstract computation goals without any dependencies to existing applied services. It is proposed to rely on the centralized scheme to organize the computations (named as orchestration) and to put to the knowledge base the set of rules used to build (in multiple steps) the concrete computational scenario from the abstract goal. It is proposed to include the computing task’s execution subsystem to the software architecture of the applied system. This subsystem is composed of the service which is processing the incoming requests for execution, the service registry and the orchestration service. The clients send requests to the execution subsystem without any references to the real-world services to be called. The service registry searches the knowledge base for the corresponding input request template, then the abstract operation description search for the request template is performed. Each abstract operation may already have its implementation in the form of workflow composed of invocations of the real applied services’ operations. In case of absence of the corresponding workflow in the database, this workflow implementation could be synthesized dynamically according to the input and output data and the functionality description of the abstract operation and registered applied services. The workflows are executed by the orchestrator service. Thus, adding some new functions to the client side can be possible without any changes at the server side. And vice versa, adding new services can impact the execution of the calculations without updating the clients.

New and efficient paradigms for web-based collaborative product design in a global economy will be driven by increased outsourcing, increased competition, and pressures to reduce product development time. We have developed a three-tier (client-server-database) architecture based collaborative shape design system, Computer Aided Distributed Design and Collaboration (CADDAC). CADDAC has a centralized geometry kernel and constraint solver. The server-side provides support for solid modeling, constraint solving operations, data management, and synchronization of clients. The client-side performs real-time creation, modification, and deletion of geometry over the network. In order to keep the clients thin, many computationally intensive operations are performed at the server. Only the graphics rendering pipeline operations are performed at the client-side. A key contribution of this work is a flexible architecture that decouples Application Data (Model), Controllers, Viewers, and Collaboration. This decoupling allows new feature development to be modular and easy to develop and manage.

In a typical DoS attack, the attacker tries to bring the server down. In this case, the attacker sends a lot of bogus queries to the server to consume its computing power and bandwidth. As the server’s bandwidth and computing power are always greater than attacker’s client machine, He seeks help from a group of connected computers. DDoS attack involves a lot of client machines which are hijacked by the attacker (together called as botnet). As the server handles all these requests sent by the attacker, all its resources get consumed and it cannot provide services. In this project, we are more concerned about reducing the computing power on the server side by giving the client a puzzle to solve. To prevent such attacks, we use client puzzle mechanism. In this mechanism, we introduce a client-side puzzle which demands the machine to perform tasks that require more resources (computation power). The client’s request is not directly sent to the server. Moreover, there will be an Intermediate Server to monitor all the requests that are being sent to the main server. Before the client’s request is sent to the server, it must solve a puzzle and send the answer. Intermediate Server is used to validate the answer and give access to the client or block the client from accessing the server.

Increasing demands on user interface (UI) usability, adaptability, and dynamic behavior drives ever-growing development and maintenance complexity. Traditional UI design techniques result in complex descriptions for data presentations with significant information restatement. In addition, multiple concerns in UI development leads to descriptions that exhibit concern tangling, which results in high fragment replication. Concern-separating approaches address these issues; however, they fail to maintain the separation of concerns for execution tasks like rendering or UI delivery to clients. During the rendering process at the server side, the separation collapses into entangled concerns that are provided to clients. Such client-side entanglement may seem inconsequential since the clients are simply displaying what is sent to them; however, such entanglement compromises client performance as it results in problems such as replication, fragment granularity ill-suited for effective caching, etc. This paper considers advantages brought by concern-separation from both perspectives. It proposes extension to the aspect-oriented UI design with distributed concern delivery (DCD) for client-server applications. Such an extension lessens the serverside involvement in UI assembly and reduces the fragment replication in provided UI descriptions. The server provides clients with individual UI concerns, and they become partially responsible for the UI assembly. This change increases client-side concern reuse and extends caching opportunities, reducing the volume of transmitted information between client and server to improve UI responsiveness and performance. The underlying aspect-oriented UI design automates the server-side derivation of concerns related to data presentations adapted to runtime context, security, conditions, etc. Evaluation of the approach is considered in a case study applying DCD to an existing, production web application. Our results demonstrate decreased volumes of UI descriptions assembled by the server-side and extended client-side caching abilities, reducing required data/fragment transmission, which improves UI responsiveness. Furthermore, we evaluate the potential benefits of DCD integration implications in selected UI frameworks.

There is a need to be able to verify plaintext HTTP content transfers. Common sense dictates authentication and sensitive content should always be protected by SSL/HTTPS, but there is still great exploitation potential in the modification of static content in transit. Pre-computed signatures and client-side verification offers integrity protection of HTTP content in applications where SSL is not feasible. In this chapter, the authors demonstrate a mechanism by which a Web browser or other HTTP client can verify that content transmitted over an untrusted channel has not been modified. Verifiable HTTP is not intended to replace SSL. Rather, it is intended to be used in applications where SSL is not feasible, specifically, when serving high-volume static content and/or content from non-secure sources such as Content Distribution Networks. Finally, the authors find content verification is effective with server-side overhead similar to SSL. With future optimization such as native browser support, content verification could achieve comparable client-side efficiency.

There are two kinds of handheld computing and programming, namely client- and server- side handheld computing and programming. The most popular applications of the latter are used with database-driven mobile web content, whose construction steps were described in the previous section. The remainder of this book will be devoted to client-side handheld computing and programming, whose applications do not need the support of server-side programs. Client-side handheld applications are varied and numerous, covering a wide range of everyday activities. Popular application examples include: • address books, which store personal information such as addresses, telephone numbers, and email addresses in an accessible format, • appointments, which allow users to edit, save, and view times reserved for business meetings and visits to the doctor, • calculators, which may be a standard 4-function pocket calculator or a multifunction scientific calculator, • datebooks/calendars, which allow users to enter hourly activities and show a daily or weekly schedule, or a simple monthly view, • expenses, which allow users to track and record common business expenses such as car mileage, per diems, air fees, and hotel bills, • mobile office functions, which include viewing and processing documents, spread sheets, presentations, and inventory. • multimedia, which includes playing music and videos, photography, and personal albums. • note pads, which allow users to save, view, and edit text notes, • to-do lists, which allow users to enter a list of tasks to be performed, and • video games, in addition to those on-line video games that require the support of server-side programs.
