Avoid the hassle of repeatedly importing global SCSS variables for Angular components

Question

Avoid the hassle of repeatedly importing global SCSS variables for Angular components

I have defined SCSS variables in the file

src/styles/settings/_variables.scss

and imported them into src/styles.scss. However, these variables are not available for every component.

Is there a way to create a global file that contains all SCSS variables for all my components? It is cumbersome to include @import in every component's .scss file, especially with nested components.

I know there are similar questions, but they seem outdated and do not apply to the latest versions of Angular.

I am using Angular 7.3 with CLI.

Answer №1

To enhance your configuration, consider enclosing your global variable declarations within the :root{} selector in the

src/styles/settings/_variables.scss

file.

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

When using these variables in SCSS, make sure to reference them like this:

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

In addition, this technique can extend beyond colors and fonts to include mixins, media queries, keyframes, and more. The possibilities are not limited to just styling attributes.

To further organize your styles, create a global file at src/assets/style/global and import each individual scss file into it as needed.

@import 'filename';

If you wish to prevent certain components from accessing global variables once they are implemented, explore how ViewEncapsulation in Angular can help isolate these styles.

Is there a way to have global access to scss variables in all components?

Unfortunately, it is not possible to automatically have access to the sass variables without importing the global file in each component.

In SASS, when using partials to organize code better, you can use the @import directive to reference shared variables. For example, if you have sass variables in a file called shared/_variables.scss:

$lightslategray: #778899;
$darkgray: #A9A9A9;

If you want to use these variables in another stylesheet, you need to import the stylesheet that contains them first:

// Shared
@import "shared/variables";

.content {
  background: $lightslategray;
}

In Angular, referencing external stylesheets works similarly. If you need to use some

sass variables, mixins, or functions

in a specific component.scss, you must use the @import directive to reference them in that file. To simplify this process, you can create a file named src/_variables.scss and use syntax like this in your component.scss:

@import “~variables.scss”;

Accessing sass styles globally is a breeze with just two simple steps.

Add the folder path of your style files to the includePaths array in the angular.json file.
Import specific style files by their filenames in any component as needed.

For example, if your file and folder structures look like this: src > my-styles-folder > var.scss

angular.json

"architect": {
  "build": {
    ...
    "options": {
      "stylePreprocessorOptions": {
        "includePaths": [
          "src/my-styles-folder" // Just add the path without the file name
        ]
      },
      "styles": [
        ...
      ]
    }
    ...
  }
}

var.scss

$toolbar-heigh: 70px;

some-component.scss

@import "var"; // Import var.scss

mat-toolbar {
  height: $toolbar-height;
}

First, navigate to the custom SCSS file located at shared/css/_variable.scss and add the following:

:root{
  --color-text: red;
  --color-btn-success: green;
}

Next, open the style.scss (main file) and import the variables file:

@import './shared/css/Variables';

You can now utilize these variables in all components using this syntax:

.sample{
  color : var(--color-text);
}

When using angular 8, this solution worked well for me.

To customize your styles in Angular, you need to modify the _variable.scss file as follows:

:root{--my-var:#fabada}

Next, navigate to your angular.json file and update the "styles" section with the following line:

{"input":"yourPath/_variables.scss"}

Answer №6

A quick way to streamline your stylesheets is by utilizing the :root{--my-var:#fabada} declaration in your styles.scss/css instead of relying on an additional _variables file. This allows you to simply reference var(--my-var) within any component.

Answer 13

Answer №7

After much experimentation, I discovered that the most effective method to accomplish this task is by translating scss variables into css custom properties.

Within the _variables.scss file, all scss variables are stored:

$purple: hsl(270, 60%, 50%);

Subsequently, I transform them into standard css variables:

:root {
    --purple: #{$purple};
}

Utilize variables from external files within each angular component:

@use "/src/styles/settings/variables" as *;

Once you import your variables, they will be accessible in your component. I trust this information proves helpful to you.
