Global scss variables for Angular components without importing them everytime

Question

I do already have SCSS variables defined in src/styles/settings/_variables.scss and I am importing them into src/styles.scss, but still these variables aren't available for every single component.

Is there any way to make a global file which holds all SCSS variables for the rest of my components? Because writing @import in every single component .scss file it is very frustrating, especially if I have many nested components.

I know, there is a lot of similar questions, but it seems like they're all outdated and do not relate to the recent versions of Angular.

I use Angular 7.3 with CLI.

You just need to add a little more config, so where you are declaring your global variables, you need to wrap it up in :root{}. So in src/styles/settings/_variables.scss.

:root  { --blue: #00b; // or any global you wish to share with components  } 

Then when you use them in the SCSS you will need to access them like so.

.example-class {   background-color: var(--blue) } 

To add to this regarding comments, this method can use mixins, @media and keyframes and is not limited to just colours / font. That was an example.

From my understanding you need a global file src/assets/style/global and then to import each scss file into there where you are defining them like so.

@import 'filename'; 

If you dont want global variables to be used in within a component look when you have the globals working. Look into ViewEncapsulation, as this can be used to ignore them.
