This is a blog about extending Qlik Sense. Qlik Sense has excellent support for using Qlik objects in your own web page or app. With the tools supplied with the product you can drag-and-drop charts from your Qlik app into a web page and get it injected into basically any web page without programming. That is not what this blog is about.
Looking at the material I have for this blog I realize that some of it (possibly all of it) is not easy. You need to know a bit about programming and have an interest in learning more. You probably also need to know something about Qlik.
