The aim of the thesis is to analyse framework IONIC and determine the suitability of this framework for cross-platform mobile development. The intent of the theoretical part is to analyse the current market, introduction to the mobile development and a description of the framework IONIC and related technologies. The practical part deals with the analysis and design mobile application PowerFLOW, describing the implemented mobile application and sample code. The last part is about framework IONIC evaluation based on set criteria. The evaluation rating was determined on the experience gained during the implementation of mobile application PowerFLOW. There are also listed personal experience of the implementation. Based on this thesis the IONIC can be recommended as the framework for cross-platform mobile development.

Mobile applications can be developed using a variety of different techniques and technologies. One of the most recent of these techniques is the Progressive Web Application (PWA), a cross-platform solution that is built exclusively using common web technologies. The technique has great potential to become a major competitor to native applications but is currently held back by a few rather significant limitations. This project was initiated because of a significant lack of academic research on the topic of PWA, and a perceived poor level of knowledge in the industry about the technique. The goal of the project was to determine if PWA deserved broader utilization or if the current low level of adoption was justified. During the project, two surveys were conducted. The first survey asked mobile application developers from companies in different countries about things such as their knowledge of, experience with, and opinions of PWA. The second survey asked similar questions but was instead answered by lecturers in higher education in Sweden only. The results of this project show that the average level of knowledge of PWAis very low and that developers’ opinions of the technique are quite negative. The limitations of PWA were found to be few but crippling to its potential to achieve widespread adoption.

Mobila enheter så som mobiltelefoner och surfplattor är idag väldigt vanliga i arbetslivet, där de inte bara används för kommunikation utan även för att utföra arbetsuppgifter. Alla verktyg finns dock inte alltid tillgängliga för sådana enheter eller i alla fall inte i en form som gör det praktiskt att använda dem. Systemet Semko Instrument Register (SIR), utvecklat av Triona, är ett sådant verktyg i form av en ej mobilanpassad hemsida, som bland annat används för att hämta kalibreringscertifikat för mätinstrument. Målet med detta projekt är att komma fram till ett sätt att tillgängliggöra systemet på så många olika typer av mobila enheter som möjligt, på ett så enkelt sätt som möjligt. Olika metoder (mobilanpassade webbsidor, plattformsspecifika applikationer och plattformsoberoende applikationer) jämförs och analyseras, med fokus på möjligheter till att använda samma kod på flera plattformar samtidigt och huruvida de kan uppfylla kraven som är ställda på applikationen eller ej. Designförslaget tar upp ett sådant sätt, som sedan utvärderas med hjälp av olika aspekter, exempelvis mängd kod som kan återanvändas på flera plattformar. Slutsatsen är att det bästa sättet att tillgängliggöra en tjänst på så många plattformar som möjligt är genom mobilanpassade webbsidor, men på grund av de krav som ställts på projektet användes istället Ionic, ett webbteknologi-baserat verktyg för plattformsoberoende applikationsutveckling, då moderna webbläsare ej ännu har den funktionalitet som krävdes. / Mobile devices such as smartphones and tablets are very common at companies nowadays, where they’re not just used for communication but also for doing work. Not all tools are available for such devices though, or at least not in a suitable form that makes it practical to use them. Semko Instrument Register (SIR) is a such a system, developed by Triona, in the form of a website that is not adapted for mobile devices, which is used for downloading calibration certificates for measuring instruments among other things. The goal of this project is to come up with a method of making the system available to as many mobile devices as possible in the simplest way possible. Different methods (websites adapted for mobile devices, native applications and cross-platform applications) are compared and analysed with a focus on possibilities for sharing code on multiple platforms and whether they’re able to fulfill what is required of the application. The design chapter presents such a method which is then evaluated on different aspects, such as the amount of code that can be shared between platforms. The conclusion is that the best way of making a system available on multiple platforms is through websites adapted for mobile devices, but because of this particular system’s requirements a cross-platform solution called Ionic was used instead, as modern mobile browsers are not yet able to fulfill what was required of the application.
