Visual Studio Code cannot find VisualUpdateOptions

[ConnectedRoman]

Hello,

I'm currently trying to learn how I can create custom visuals and PowerBI.

This is the guide I'm following. I'm stuck at the "Adding Databinding to Bar Chart" part. Specifically where I have to create the visualTransform function. 

When I write the method head, Visual Studio Code underlines "VisualUpdateOptions" and "IVisualHost" red, saying it can't find those. 

I have copied the dependencies from the package.json on github into the package.json of my project and installed them. I also added all the dependencies into the pbiviz.json and tsconfig.json.

When I download the project from github and run it it works, without being underlined.

What am I missing?

UPDATE: The problem was that I didn't specify the barChart.ts file in the tsconfig.json.

Hi ConnectedRoman,

From what I see from the code you provided, it seems Visual Studio Code [using pbiviz new ... ] has generated a v1.7.0 version while the sample demo you're refering to was built in an earlier v1.5.0 version. So if you use any portion of the sample demo "AS-IS" - particularly pbiviz.json or tsconfig.son this may generate conflicts with your version some point and may be the reason you see the error. 

So in order to avoid conflict and use demo code sample "AS-IS" you'll either have the choice to import a v1.5.0 code version in your app, under the .api folder



or keep your existing v1.7.0 version and make a double-check to make sure any piece of code you may have borrowed from demo sample is pointing to the right version, especially pbiviz.json

and tsconfig.json

Thank you very much for your answer, that's something I didn't consider.

The problem was fixed when I added the barChart.ts to the tsconfig.json "files" member. I missed that I have to add everything to that file, as I'm pretty new to TypeScript.
