VS code: indent single line with tab

Question

I have been using Emacs for a very long time and now I want to switch to something modern like VS code. One thing that I really used to in Emacs is auto indentation with a Tab key:

http://www.gnu.org/software/emacs/manual/html_node/emacs/Indentation.html

Turned on with tab-always-indent

I want VS code not to add a tab symbol when Tab is pressed, but auto indent a single line like Emacs does, how do I configure that?

Here is an example in Javascript:

function foo(){
    }  // Press Tab here

In Emacs the result will be (and I want the same in VS code):

function foo(){
}

so the bracket will go to the beginning of line, but the result in VS code will be

function foo(){
        } // second tab added

Emacs does indentation according to the current text mode (Python/JS/C++/Whatever).

PS. I know I can select a region of code and use "Format Selection" or do auto-formatting on save.

Alex, for which mode you want such behaviour? Most modes I'm using now: go, python, javascript - I use autoformat on save (for go - it's unswitchable, python - yapf, javascript - eslint). I suppose that you mean some of the "text" modes. Which? — Alex Yu
I suppose you can play with code.visualstudio.com/docs/getstarted/… I never tried (yet) but it looks promising - it allows custom bindings for language ids. Thank for the question! — Alex Yu

This only partly answers your question --- making Tab to indent-line --- it doesn't normalize indentation as you want. But, you could set it to some other command which may do what you want.

Plus it but breaks a few cases.

{
    "key": "tab",
    "command": "editor.action.indentLines",
    "when": "editorTextFocus && !suggestWidgetVisible && !inSnippetMode"
}

Where it yields to default behavior:

when using Tab to confirm a intellisense dialog (autocomplete)
when jumping to snippet placeholders

What it breaks:

pressing Tab to indent to the level of current block
expanding snippet cannot be done right after writing the snippet prefix (you need to wait for the intellisense to open)
maybe something else...
