<p>Note: this feature is available with <code>react-scripts@2.0.0</code> and higher.</p>
|
||
</blockquote>
|
||
<p>Generally, we recommend that you don’t reuse the same CSS classes across different components. For example, instead of using a <code>.Button</code> CSS class in <code><AcceptButton></code> and <code><RejectButton></code> components, we recommend creating a <code><Button></code> component with its own <code>.Button</code> styles, that both <code><AcceptButton></code> and <code><RejectButton></code> can render (but <a href="https://facebook.github.io/react/docs/composition-vs-inheritance.html">not inherit</a>).</p>
|
||
<p>Following this rule often makes CSS preprocessors less useful, as features like mixins and nesting are replaced by component composition. You can, however, integrate a CSS preprocessor if you find it valuable.</p>
|
||
<p>To use Sass, first install <code>node-sass</code>:</p>
|
||
<pre><code class="hljs css language-sh">$ npm install node-sass --save
|
||
$ <span class="hljs-comment"># or</span>
|
||
$ yarn add node-sass
|
||
</code></pre>
|
||
<p>Now you can rename <code>src/App.css</code> to <code>src/App.scss</code> and update <code>src/App.js</code> to import <code>src/App.scss</code>.
|
||
This file and any other file will be automatically compiled if imported with the extension <code>.scss</code> or <code>.sass</code>.</p>
|
||
<p>To share variables between Sass files, you can use Sass imports. For example, <code>src/App.scss</code> and other component style files could include <code>@import "./shared.scss";</code> with variable definitions.</p>
|
||
<p>This will allow you to do imports like</p>
|
||
<pre><code class="hljs css language-scss">@<span class="hljs-keyword">import</span> <span class="hljs-string">'styles/_colors.scss'</span>; <span class="hljs-comment">// assuming a styles directory under src/</span>
|
||
@<span class="hljs-keyword">import</span> <span class="hljs-string">'~nprogress/nprogress'</span>; <span class="hljs-comment">// importing a css file from the nprogress node module</span>
|
||
</code></pre>
|
||
<blockquote>
|
||
<p><strong>Note:</strong> You must prefix imports from <code>node_modules</code> with <code>~</code> as displayed above.</p>
|
||
</blockquote>
|
||
<p><code>node-sass</code> also supports the <code>SASS_PATH</code> variable.</p>
|
||
<p>To use imports relative to a path you specify, and from <code>node_modules</code> without adding the <code>~</code> prefix, you can add a <a href="https://github.com/facebook/create-react-app/blob/master/docusaurus/docs/adding-custom-environment-variables.md#adding-development-environment-variables-in-env"><code>.env</code> file</a> at the project root with the variable <code>SASS_PATH=node_modules:src</code>. To specify more directories you can add them to <code>SASS_PATH</code> separated by a <code>:</code> like <code>path1:path2:path3</code>.</p>
|
||
<p>If you set <code>SASS_PATH=node_modules:src</code>, this will allow you to do imports like</p>
|
||
<pre><code class="hljs css language-scss">@<span class="hljs-keyword">import</span> <span class="hljs-string">'styles/colors'</span>; <span class="hljs-comment">// assuming a styles directory under src/, where _colors.scss partial file exists.</span>
|
||
@<span class="hljs-keyword">import</span> <span class="hljs-string">'nprogress/nprogress'</span>; <span class="hljs-comment">// importing a css file from the nprogress node module</span>
|
||
</code></pre>
|
||
<blockquote>
|
||
<p><strong>Note:</strong> For windows operating system, use below syntax</p>
|
||
<pre><code class="hljs"><span class="hljs-attr">SASS_PATH</span>=./node_modules;./src
|
||
</code></pre>
|

||
<p><strong>Tip:</strong> You can opt into using this feature with <a href="/docs/adding-a-css-modules-stylesheet">CSS modules</a> too!</p>

</blockquote>
|
||
<blockquote>
|
||
<p><strong>Note:</strong> If you're using Flow, override the <a href="https://flow.org/en/docs/config/options/#toc-module-file-ext-string">module.file_ext</a> setting in your <code>.flowconfig</code> so it'll recognize <code>.sass</code> or <code>.scss</code> files. You will also need to include the <code>module.file_ext</code> default settings for <code>.js</code>, <code>.jsx</code>, <code>.mjs</code> and <code>.json</code> files.</p>
