Tips for integrating Angular 4 with SASS

As I embark on my inaugural project utilizing Angular4 and sass, I am grappling with the best approach for working with sass. My setup involves using angular-cli with a default style configuration set to utilize scss syntax. I have also configured the compilation process accordingly.

However, I have encountered an issue with the styleUrls option in the component, where specific styles are designated for use only within that component.

The dilemma arises when I specify a scss file in a particular component, as it fails to generate its own corresponding .css file or include it within the main .css file generated from the root of the project.

My project structure is organized as follows:

app
    app.module.ts
    app.routing.ts
    home
        home.component.ts
        home.html
        _home.scss
    client
        client.component.ts
        client.html
        _client.scss
scss
    _imports.scss
    colors
        _colors.scss
    ui
        _button.scss
        _table.scss
    //.. more folders and files
styles.scss
index.html

I aim to define the primary css style in the styles.scss file, which will later be injected into the index.html file during the build process. Additionally, I want the ability to generate a separate css file for each individual component, such as home and client, and exclusively apply those styles within their respective components.

Is there a way to achieve this desired functionality? Despite my attempts, I have yet to come across any other resources addressing this specific challenge!

If you're searching for it, what you need is the import directive:

@import "styles.scss";  
@import "css/styles.scss";  
@import url("http://example.com/css/styles.scss");

This function brings in the CSS from different CSS files into the main CSS file, adding each file's contents to the main file according to the order you specify.

Remember that you don't have to include the .scss file extension because SASS takes care of that automatically. You can simply import with @import "file". Also, there's no need to list each file separately for import; you can consolidate them all in a single import statement:

@import "styles.scss", "css/styles.scss", url("http://example.com/css/styles.scss");

You can even nest imports by using the @import within a selector:

.global-nav {  
  @import "nav-bkgd";
}

I hope this information proves useful! :)

To implement styling changes in an Angular 4.4+ project using ng-cli, simply adjust the settings within the .angular-cli.json file as shown below:

{
  ...
  "apps": [
    ...
    "styles": [
        "styles.scss"
      ],
      ...
  ]
  ...
  "defaults": {
    "styleExt": "scss",
    "component": {}
  }
}

If needed, modify the file extensions within each component from .css to .scss like so:

@Component({
    selector: 'app-your-component',
    styleUrls: ['./your-component.component.scss']
})

If you want to use scss in your project, you can specify it during project creation.

ng new my-project --style scss

I encountered a similar issue recently with my left navigation component. It seemed like the SCSS file was not being compiled, despite trying various solutions. I even started a new app using ng new command, but that didn't solve the problem. Eventually, I fixed it by changing my approach and thinking outside the box.

It appears that using the same component selector inside its relative .scss file may cause issues. Instead, wrapping the content in a div with a suitable className and using that className as the root wrapping of the .scss file content is a better approach.

Let me illustrate this with an example:

app/component/leftnav
  |leftnav.scss
  |leftnav.html ==> simply `left nav works!`
  |leftnav.ts ==> selector leftnav
app/
  |app.html
  |app.scss

In the original leftnav.scss file:

leftnav{
    background:red;
}

In app.html:

<leftnav></leftnav>

To resolve the issue, I added a wrapping div with the className .leftnav inside leftnav.html and used it as the root wrapping in my leftnav.scss instead of the component selector.

So my new leftnav.scss contains:

.leftnav{
    background:red; 
}

And it worked flawlessly!

If your project is already up and running, using ng new my-sassy-app --style=scss won't work. Instead, you need to update the default style extension by using ng set defaults.styleExt scss. This will modify the angular.cli.json file as shown below:

"defaults": {
  "styleExt": "scss",
  "component": {
 }
}

Next, go ahead and change all existing css files to use the scss extension. You should notice that now scss is functioning properly. Remember to also update the file extensions in your component definitions from css to scss. Check out the source for more information.
