The aim of my thesis is to provide a collection of examples about document oriented MongoDB database using Node.js platform, specifically using the Mongoose program, for object-document mapping (ODM). The aim is met by analysis of Mongoose and Async module, which provides functions for more comprehensive asynchronous querying, needed for working with input/output to the MongoDB database in Node.js. The main merit of this thesis is (in the general sense) a demonstration of how to create a administration part of web application (backend) in Node.js, applying document oriented MongoDB database. The thesis discusses, in the theoretical part, about characteristics and significance of document oriented MongoDB database, about characteristics and architecture of Node.js platform employing untyped and multiplatform JavaScript language and about object document mapping (ODM) programs for Node.js on MongoDB. The practical part contains a collection of examples, where in the first chapter introduces an instalation and execution manual of necessary programs. The next chapter is dedicated to simple examples of Mongoose module and in the last chapter there are stated the complex examples of Mongoose and Async modules, which are the main merits of this thesis.

The thesis is concerned with comparison of web application development platforms, namely Nette Framework on PHP platform and platform Node.JS. The objective is to provide complex picture of differences between the frameworks. Previous theses compared Grails framework on Java platform, Zend Framework on PHP platform and ASP.NET MVC platform. This thesis builds upon them thus provides comparison of five different platforms for web application development. As a part of the thesis, I developed two web applications. One is in Nette Framework in PHP and one is in Node.JS. Their purpose is to be main source of information for the comparison. Furthermore, beginning developer learning new platform can use them as a study material. They can also help to examine platform differences. Applications I developed meet same user requirements as the applications contained in previous theses. Therefore it is possible to compare all five applications on five platforms with each other. The platforms are compared in several areas. First area focuses on fundamental platform differences. Second area is more theoretical. It concerns the platform architecture. Platforms are judged by amount of the support for Martin Fowler's architectonical patterns. Next area concerns platforms' usage during the web application development. There are both objective criteria as well as subjective evaluation based on the application development included. The last area compares available support of the platforms. Thesis provides complex comparison of five different platforms by same criteria. Developed web applications, based on same requirements, are also a benefit. Potential reader can form her own judgement based on the differences in implementation of same functionality she founds on different platforms.

This work deals with communicating issues in public space from citizens to municipalities. The main objective is the creation of a system for reporting those issues using smartphone. The first chapter contains the analysis of existing foreign and domestic projects focused on issues mapping. The second chapter focuses on analysis and design of a new system. The third chapter discuses variants of technologies available for each part of the system. The fourth chapter describes choice of technologies and development of individual parts of the system.

The goal with this project has been to develop an application where a user can create and manage tournaments that uses the Swiss format. The application would consist of one display page that can be used to show the current state of the tournament for all the competitors, and one admin page where a user can update match results and generate a new round of matches. The application has been developed with Node.js on the server side and the JavaScript library React on the client side. All the React code is written in the modern way with functional components and the usage of React Hooks. The document based database MongoDB has been used for the application. Real time-updates has been implemented with the library Socket.IO The project has led to a well-functioning application where a user can create och manage a tournament and where all the updates are done in real time in a neat and smooth way. The creator of the tournament can share both the admin page and the display page to other people who want to see the tournament result by sharing the link to the specific tournament. / Målet med denna projektuppgift har varit att utveckla en applikation där användare kan skapa och hantera turneringar som använder sig av Swiss-formatet. Applikationen skulle bestå av dels en uppvisningssida som kan användas till att visa upp turneringens aktuella resultat för medtävlande och dels en administrationssida där en användare kan uppdatera matchresultat och generera en ny omgång matcher. Applikationen har utvecklats med Node.js till serversidan och JavaScript-biblioteket React på klientsidan. All React-kod är skriven med funktionskomponenter och React Hooks, vilket är det moderna sättet att utveckla i React på. Som databas till applikationen har en dokumentbaserad databas använts: MongoDB. Realtidsuppdateringarna har möjliggjorts med hjälp av biblioteket Socket.IO. Projektet har lett till en väl fungerande applikation där en användare kan skapa och hantera en turnering, och där alla uppdateringar sker i realtid på ett snyggt och smidigt sätt. Skaparen av turneringen kan dela med sig både administrationssidan och uppvisningssidan till andra personer som vill se turneringsresultaten genom att dela länken till den specifika turneringen.

This thesis is focused on requirements analysis of a sawmill company for a new timber stock evidence system and based on the analysis describes the process of development of the system. The process covers architecture and structure design as well as data storage solution. Apart from the development stage itself, it also covers the implementation of the system in the company’s environment and economic evaluation of the process. The system is being developed using the Javascript programming language and uses modern technologies such as React, Node.js and MongoDB.

This thesis deals with the design and implementation of a tool for generating parts of client applications in TypeScript language from the description of a REST interface. The goal of the tool is an automatic generation of an application skeleton which uses the Angular framework including data structures and services enabling access to server endpoints. The thesis describes the interfaces based on the REST architectural style, as well as the technologies used for their description. The tool was implemented in TypeScript language and uses the Node.js runtime. The output file generation is based on the Mustache.js template system. The result is a tool which allows the generation of source code based on the provided WADL or OpenAPI interface description, which can be simply used as a part of an Angular application.

This thesis is focused on developing software with ITSM integration features. The aim of this work is to design a suitable software architecture for integration applications in a cloud environment. Due to the use of the solution for many customers, emphasis is placed on sustainability and reusability. After wide technology analysis, a web application has been created that is fully configurable to meet a wide range of customer needs. It is decided to use the Node.js environment and the Loopback 4 framework for application development. To ensure lower costs for the operation of cloud resources, compared to competing technologies such as Java. The entire system is deployed in IBM Cloud. The resulting application is put into production by IBM.

The aim of this thesis was to create an information system which consists of a mobile application, server and web application. Mobile application is designed for operating system Android and it is used for sending GPS coordinates of mobile devices to the server. These data are later processed by server and stored in database. Web application displays the current location of mobile devices in user group on a map, it also displays location history and statistics. Accuracy of the station location can be enhanced by using DGPS assuming that one of stations in a group does not change its location. The system was designed and then developed using modern web technologies and frameworks including PhoneGap, Ionic, Node.js, Express, MongoDB, Mongoose and AngularJS. Further measurements, that were performed, are supposed to present the effect of DGPS to location accuracy determination.

Följande arbete jämför databashanterarna MongoDB och Couchbase responstid i att hämta data i en Node.js REST api. Datasetet har en enkel struktur och består av befolkningsdata. Jämförelsen ska svara på vilken av dessa databashanterare som har kortast responstid i att hämta befolkningsdata i en Node.js REST api, eftersom responstiden är väldigt viktig för användare. Testet sker med egenutvecklade script och mäter tiden det tar att skicka en begäran till REST api:t och visa den hämtade datan på webbläsaren. REST api:t består av 5 endpoints vilket testades 6000 gånger var för MongoDB och Couchbase. MongoDB hade kortast responstid på samtliga test. I framtida arbeten kan resten av CRUD operationerna testas och då inte bara att hämta data, långsiktig kan datasetet ändras för att kunna testa mer komplexa sökfrågor.
