Power BI Developer Bootcamp is an intensive 4-day instructor-led training course with hands-on labs designed to get professional software developers up to speed on developing custom software solutions for the Power BI platform. This course assumes that incoming students already have hands-on experience creating and publishing projects with Power BI Desktop.
This course teaches students how to create custom data connectors using Visual Studio 2017, the Power Query SDK and the M programming language. Students will also learn how to develop custom visuals for Power BI using Typescript, the D3.js library and Microsoft’s recommended toolchain which includes Node.JS, Node Package Manager (npm) and the Power BI visual CLI tool (pbiviz). Along the way, students will learn how to package up a custom visual for testing purposes and for distribution to a production Power BI workspace.
The course also teaches students how to get started with the R data analytics platform and how to leverage R in a Power BI environment. Students will learn fundamental R programming syntax and become comfortable writing and testing R scripts in RStudio. The course also covers how to integrate R scripts into Power BI Desktop projects to import data and to generate charts and graphs using the R script visual. Students will also learn how to develop custom R visuals which make it possible to leverage the visualization power of the R platform while encapsulating the implementation details in a reusable custom visual.
