I'm trying to use Vaadin to make a table (technically a grid).

Someone saw a demo on vaadin's website, and basically just wants that recreated and tweaked: https://demo.vaadin.com/sampler/#ui/grids-and-trees/grid/features

I downloaded the starter project from https://vaadin.com/start/v10-simple-ui, and I was able to tack my table onto their demo app easily.

However, the features on their demo aren't available to me. Specifically, column.setHidable(true) isn't something I can call, because the Vaadin library lacks that method, even though it's in their demo.

I'm wondering if that's because the demo lied about vaadin's capabilities, or because I haven't downloaded the right part of a modular application.

I am trying to set up a small gulp script for the following actions:

1. Concatenate all Javascript files into one
2. Uglify this built Javascript file
3. Compile all SASS files to CSS
4. Minify these CSS files

In addition, I'd like to save the results of step 1 and 3 into one folder (developer version) and the results of step 2 and 4 into another (productive version). The problem is, gulp doesn't seem to find the generated files in step 2 and 4, so it always builds the files depending on the old version of the files. The workaround for this problem is to always run my gulp script twice. Does anyone know why this is the case and how I could fix that problem?

I am creating an angular application and I'm using Springboot for backend API's with postgresql database.

I need to make my application fully featured as well as responsive with Rich UI.

I have searched for many modules and packages that can help to build my angular2 app. I got some of them, such as; ngx permissionsModule, angular-simple-ui module, angular2-permissions module, etc.

So how can my application get facilitated from angular side?

Which features of angular should i use for my applications?

Please suggest me some key points to elaborate the angular2 side.
