Det här är till för att skapa ett system där andra webbutvecklare kunde skapa sina hemsidor online. Det webbutvecklaren inte behöver tänka på är att ha en egen webbserver, vilket kan vara ett problem för många om dom sitter vid datorer med begränsade rättigheter så att dom inte kan ladda ner och installera en webbserver. En annan bra fördel är att webbutvecklaren kan logga in vart som helst, när som helst och redigera koden till en hemsida. Skulle webbutvecklaren vilja ha sitt projekt på en egen webbserver, går det enkelt att ladda ner projektet.

The goal of this thesis is to design and develop a framework for building modern single- page application in the JavaScript programming language and describe this approach to development. The work also contains the documentation for a more comfortable use and customization. The content is divided into eight chapters. The introduction is followed by the retrieval of information resources, including the specifics of the JavaScript programming language and explanation of the formation of single-page application. The description of the basic principles of their functioning, motivation and justification, when and why this approach is appropriate is also included. The work is primarily focused on the issue of single-page application, for which the use of the JavaScript programming language is crucial. For this reason, this work provides a whole chapter about this programming language, also including a description of its history and role in the context of others. Below are the common characteristics of single-page applications frameworks, built on top of the library ReactJS, whose formation is engaged in the following chapter. The developed framework also contains the user guide. The practical outcome of this work is an open source framework for creating serverless single-page applications, which is due to its architecture and documentation appropriately adaptable.

The diploma thesis deals with the proposal and succeeding implementation of the municipal information portal for the municipality of Radošov. It takes into account legal specifications for information providing and publishing in the public administration and also some current trends in the websites development. The thesis also contains a critical evaluation of the present state of the municipality official website.

For my thesis work I have done an evaluation of the newly released Microsoft developed web framework Blazor. My methodology is based upon a couple of previous articles about evaluating web frameworks. From these articles I have gathered a number of criteria used in my evaluation: documentation, lines of code,community size, framework usage, framework maturity, framework freshness, browser support and framework cost. Additionally, since Blazor is based on C# instead of JavaScript, I have included a 9th criterion, comparing JavaScript with C#. Many of the criteria need some kind of counterpart for Blazor to be compared with, for this purpose I have mainly used the established web framework Angular, and in some cases Ember.js. When evaluating, I have not expected Blazor to exceed Angular. Rather I have counted all cases where Blazor can at least be considered comparable to Angular (or Ember.js) as favourable.I found that overall Blazor did very well in the comparison as 6 out of the 8 criteria I took from the articles evaluated favourably for Blazor. The two criteria where I found Blazor lacking were framework usage and framework maturity. While there are large numbers of showcases and example sites I did not find any large production websites developed with Blazor, and for obvious reasons the framework that was officially released earlier this year has yet to reach a mature state. Furthermore I found the extra criteria, JavaScript vs C#, was favourable to Blazor.Thus, my conclusion is that Blazor is certainly worth picking up for new projects. I argue that even though the framework is not yet fully mature it has come far in its short lifespan, and that even though Blazor is not widely used yet it is unlikely to go away considering that it is developed and supported by a large company like Microsoft.

Web applications are used more and more and mainly they are developed with the help of Javascript, but when you have heavy demanding processes in a web app, javascript can be too slow. The new language WebAssembly is an alternative that seeks to solve this problem. But unlike Javascript, there are many compilers for many different languages that have WebAssembly as their compilation goal. This means that the choice of language to compile from could make a difference when it comes to execution time. This article takes a closer look at two of the most popular languages, namely C and Rust, to see if language choice makes a difference. The differences between the languages are measured with the help of tests done between a server and a client and also with the help of an analysis of the WebAssembly code. The result shows that Rust is faster than C in matrix multiplication and insertion sort but the addition test shows that the languages are similar in speed.

This thesis deals with the theory of creating modern web applications. Various technologies that are commonly used are analyzed. Thesis mainly deals with creating specific application for processing Warranty Claims. The application serves as a service for eshops.

This work deals with creating and providing mocked data for applications that use REST interface to communicate between the client and server parts. From the various implementations of the REST interface, the work focuses only on OData standard. The project itself is mainly for SAP company. Naturally, even the libraries that are used in the final solution are from SAP. Primaly JavaScript framework SAPUI5 is used. The merit of this work is a library that facilitates the development of the client side of web applications. It fully supports CRUD operations over OData calls. Compared to other libraries creating mocked data that always return the same static data, this one simulates the behavior of the real server. So, when DELETE method is called for a specific entity, the given entity is deleted. This functionality is enabled by the client-side database created directly in the web browser, which corresponds to the database on the server side. A similar library for OData protocol does not exist, so it is a unique solution. The solution is verified using prepared web application.

This thesis is about designing and creating 3D visualisation of interior localization using Sewio system. Visualisation is presented as web application with WebGL technology. WebGL deployment is simplified with Three.js library. For future scalability of the application, I deal with integration of Three.js into Model-View-Controller architecture. The last part of the thesis is about additional sensors and their use to make the localization more precise. There is a barometric senzor making vertical localization possible and inertial sensors useful for determining rotation of localized devices.

This diploma thesis is focused on the description and implementation of the user interface for the analysis of local DNA structures as a web application in the Vue.js framework. The local structure can be described as an alternative DNA structure which arises in a specific DNA sequence that occurs in important regions of the genome. The first part of the thesis is theoretical and examines the field of DNA research and a description of selected technologies. The second part deals with the implementation and testing of the user interface on specific DNA sequences.

The main goal of this master's thesis was development of Burp Suite extension capable of interacting with various other automated tools, accompanied with development of a web application. Chapter two contains analysis of tools commonly used in penetration testing that could benefit from the ability to share Burp Suites data or functionality. The programming languages used were Java and JavaScript. The extension acts as a gateway to inner functionality of Burp Suite. It enables exfiltration of in memory objects such as sitemap, proxy history or found issues in JSON format to other tools, and also listens for incoming data that can be inserted into it's existing modules such as Repeater, Scanner, Spider or Comparer. Frontend application was written using JavaScript library React. The web application offers a graphical visualization of issue data.
