Can't access sass variables compile error with react app - reactjs

I am creating a react app with the create-react-app and I have tried to implement SASS pre-processor by following these steps over here. So everything went well and I have developed already some parts of my application. But for a really weird reason, I now got a error on compiling after already 2 days of development, without any reason I can imagine.
{
"status": 1,
"file": "/Users/glenngijsberts/Documents/Development/toggle/src/components/sass/assets.scss",
"line": 2,
"column": 9,
"message": "Undefined variable: \"$primary\".",
"formatted": "Error: Undefined variable: \"$primary\".\n on line 2 of src/components/sass/assets.scss\n>> \tcolor: $primary;\n --------^\n"
}
So the main problem is that I get now a compile error because my assets.scss can't access the variables. Assets is imported in my App.scss which also imported variables.scss.
In my App.scss file
//Import SCSS
#import "./sass/vars.scss";
#import "./sass/popup.scss";
#import "./sass/assets.scss";
#import "./sass/utils.scss";
#import "./sass/modal.scss";
#import "./sass/dropdown.scss";
#import "./sass/visualLine.scss";
#import "./sass/dashboard.scss";
#import "./sass/tabs.scss";
#import "./sass/projects.scss";
#import "./sass/colors.scss";
What is working is:
assets.scss
//Import SCSS
#import "vars.scss";
span.brand {
color: $primary;
}
But ofcourse, I don't like to include that vars file on every scss file where I want to use a scss variable. I am not used to it either (when using just sass files with a regular webpack project).

You have to put "_" to beginning name of every file you want to globally import. So your vars.scss would be _vars.scss. Sounds weird, but works.
If it won't help, rename your files to *.sass and use sass syntax. It is simplier and would work on 100%.

How to set eslint to ignore #import from scss files

In React project, I am running linter on js and scss files. In scss files, I have used #import statement but lint gives me following error
Parsing error: Unexpected keyword 'import'
#import './../shared/variables.scss';
I want linter to ignore these #import lines.
Do I need to add any rule in in eslintrc file?
Currently I am having following import rules in config:
'import/no-unresolved': 0,
'import/no-dynamic-require': 0,
'import/no-extraneous-dependencies': 0
Is there any comment line for scss files to ignore specific line, like we have it for js files? e.g. // eslint-disable-next-line
I have gone through a lot of online sources and added babel-eslint parser as well and also passed parserOptions too but nothing is working.
According to https://github.com/eslint/eslint/issues/12752#issuecomment-571561845 :
Looks like the cause is eslint 'src/**' command. You are linting other files than JavaScript.

Global scss variables in create-react-app

In my src folder, I have assets/styles folder where my global scss files are.
In my index.scss I import them like this
#import 'assets/styles/colors.scss';
#import 'assets/styles/links.scss';
#import 'assets/styles/basics.scss';
And then in index.js, I import compiled index.css
Problem: In basics.scss I'm using variable from colors.scss and getting an error Undefined variable: \"$black\".
And the same happens in components scss files if they use variables from that file. I really don't want to import colors in every single component. Is there a way to make these 3 files global?
To work with scss in reacting I'm using Adding a CSS Preprocessor (Sass, Less etc.) (Since moved here).
UPD
Use partials when importing parts into index.scss
#import 'assets/styles/colors';
#import 'assets/styles/links';
#import 'assets/styles/basics';
The filenames should be
_colors.scss
_links.scss
_basics.scss
You can read more about this in the SASS docs under the Partial section.

Gatsby.js css: "undefined [undefined]"

with the gatsby-starter-default build, running gatbsy develop, the build shows the following output:
src/layouts/index.css
undefined [undefined]
src/components/Footer/index.module.css
undefined [undefined]
What does this mean? The build seems to have succeeded. The only clue is that both these css files #import a variables.css file which uses custom css properties like :root { --blah-color: #ff3333; }. So that seems to be the issue but what is the process that is failing / printing undefineds?
I found the answer here: https://github.com/gatsbyjs/gatsby/issues/2462
quoting relevant bits:
postcss-reporter version used by gatsby has a small issue where it
prints out undefined [undefined] for every #import ... in *.module.css
files
The printed message is annoying but harmless.

Importing same file multiple times in different files?

Eg: I want to import a file called #import 's-grid-settings' in multiple different stylus files. Is this a bad idea?
It depends :)
Stylus have two ways of “importing” other stylus documents: via #import and via #require.
The difference is that #import would import the file each time, while #require would do this only once.
#require this way could be useful to share the settings and/or some common stuff like placeholders etc. between multiple stylus files in a such way those files could be either compiled each by itself or as a bundle. If the #import was used in this case, it would include all its stuff every time it was called, while #require would do this only once at the first call.
So, the answer to your question would depend on what is there inside your file.

Why is Sencha Cmd not compiling my custom sass files

UPDATE - when I put the file here, it works, the scss file is compiled into a css file.
\workspace\packages\amc-custom-theme\sass\etc\extra.scss
But a line in index.html referencing the new css file is not added. How do I make that happen?
I'm starting to use Sencha Cmd. I put a custom sass file here:
\workspace\extApps\MyApp\sass\etc\extra.scss
But it is not being compiled into the AMC-all.css file.
For now this is the contents of the scss file:
#import 'compass';
.actionColumnIcon {
margin-right: 10px;
cursor: pointer;
}
Its just a test. But I need it to work to continue.
Try sass/all.scss instead of sass/extra.scss.
