The purpose of this study is to show how transaction data from PEPPOL can bedisplayed in an effective way. PEPPOL is used to exchange e-documents betweenpublic and private entities worldwide. When there are many transactions comingthrough every day it is important to highlight the ones that have failed, and to beable to filter the transactions. This is done with Angular 9, and because Angular is being upgraded frequentlythis study also focuses on making maintainable and readable code which will helpfuture developers. Angular Materials table is being used, to display the transactions,as it provides a simple but modern table, and above the table there is a search barwhich helps us find specific transactions. Comments are added to the code, so it is easy to tell what each code block doesand the MVC pattern is used to split up the components, models and views.

In this project assignment, the ability to create RSS feeds for Smartsign's new web application, New Publisher, has been developed. The current version of Publisher has been in its current form for a long time and is beginning to feel somewhat outdated, motivating the need for an update. The development work has been carried out in the JavaScript framework Angular, in combination with SCSS and Angular-Materials. The purpose of the work has been to create this part of the new web application, which upon implementation will provide a new, simpler, and more visually appealing interface for users who want to distribute messages to connected signage screens in the form of RSS feeds, here in New Publisher called feeds. The work has resulted in a fully functional part of the application which is ready to be put into production / I detta projektarbete har RSS-flöden för företaget Smartsigns nya webbapplikation Nya Publisher utvecklats. Publisher används för att ge företagets kunder möjlighet att leverera budskap till signage-skärmar. Den nuvarande versionen av Publisher har funnits i sin nuvarande form en lång tid och börjar nu kännas något omodern, vilket motiverar behovet av en uppdatering. Utvecklingsarbetet har genomförs i JavaScript-ramverket Angular i kombination med SCSS och Angular-Materials. Syftet med arbetet har varit att skapa denna del i den nya webbapplikationen vilket vid implementering kommer att ge ett nytt, enklare och mer visuellt tilltalande gränssnitt för användare som vill nå ut med budskap till anslutna signage-skärmar i form av RSS-flöden vilket i Publisher kallas för feeds. Arbetet har resulterat i en fullt fungerande del av applikationen vilken i sig är redo att sättas i produktion
