@zarianec Invalid indentation style, you should use tabs instead of spaces.

I think using angular wrapper for sweetalert is more preferable:

Hi @fiftin, we are just discussing that in discord. Why tabs instead of spaces if spaces is widely used and is, de facto, standard for styling js code.
Angular uses 2 spaces as indentation. Also there is a style guides from google and airbnb that suggests using 2 spaces for indentation.
Airbnb JavaScript Style Guide

Tabs used in this project initially. The question should be addressed to @twhiston.

[zarianec]

Ok, i will convert spaces to tabs and open another issue related to code style.

@zarianec thanks, that would be great. Let's pick a common and well know style guide in the new issue you create and then enforce it through the ci pipeline

[twhiston]

ii'll merge this and we can address angular wrapper stuff and style guide separately. Thanks
