{ } scss-to-css

Recursively compile all SCSS files into minified CSS.

⚡ Installation

As a global utility:

$ npm install -g @adamlui/scss-to-css

As a dev dependency (e.g. for build scripts), from your project root:

$ npm install -D @adamlui/scss-to-css

As a runtime dependency (e.g. for on-the-fly compilation), from your project root:

$ npm install @adamlui/scss-to-css

💻 Command line usage

The basic global command is:

$ scss-to-css

Sample output:

💡 Note: Source maps are also generated by default unless -S or --no-source-maps is passed.

To specify input/output paths:

$ scss-to-css [input_path] [output_path]

• [input_path]: Path to SCSS file or directory containing SCSS files to be compiled, relative to the current working directory.
• [output_path]: Path to file or directory where CSS + source map files will be stored, relative to original file location (if not provided, css/ is used).

💡 Note: If folders are passed, files will be processed recursively unless -R or --no-recursion is passed.

To use as a package script, in your project's package.json:

  "scripts": {
    "build:css": "<scss-to-css-cmd>"
  },

Replace <scss-to-css-cmd> with scss-to-css + optional args. Then, npm run build:css can be used to run the command.

Example commands

Compile all SCSS files in the current directory (outputs to css/):

$ scss-to-css

Compile all SCSS files in a specific directory (outputs to path/to/your/directory/css/):

$ scss-to-css path/to/your/directory

Compile a specific file (outputs to path/to/your/css/file.min.css):

$ scss-to-css path/to/your/file.scss

Specify both input and output directories (outputs to output_folder/):

$ scss-to-css input_folder output_folder

💡 Note: Output CSS is minified unless -M or --no-minify is passed.

Command line options

Boolean options:
 -n, --dry-run                            Don't actually compile the file(s), just show if they will be processed.
 -d, --include-dotfolders                 Include dotfolders in file search.
 -S, --no-source-maps                     Prevent source maps from being generated.
 -M, --no-minify                          Disable minification of output CSS.
 -R, --no-recursion                       Disable recursive file searching.
 -q, --quiet                              Suppress all logging except errors.

Parameter options:
 --ignore-files="file1.scss,file2.scss"   Files to exclude from compilation.
 --comment="comment"                      Prepend header comment to compiled CSS. Separate by line using '\n'.

Info commands:
 -h, --help                               Display help screen.
 -v, --version                            Show version number.

🔌 API usage

You can also import scss-to-css into your app to use its API methods, both as an ECMAScript module or a CommonJS module.

ECMAScript*:

import * as scssToCSS from '@adamlui/scss-to-css';

CJS:

const scssToCSS = require('@adamlui/scss-to-css');

*Node.js version 14 or higher required

compile(input[, options])

Compiles SCSS based on the string input supplied.

If source code is passed, it is directly compiled, then an object containing srcPath + code + srcMap + error is returned:

const srcCode = 'h1 { font-size: 40px ; code { font-face: Roboto Mono }}',
      compileResult = scssToCSS.compile(srcCode);

console.log(compileResult.error); // outputs runtime error, or `undefined` if no error
console.log(compileResult.code);  // outputs minified CSS: 'h1{font-size:40px}h1 code{font-face:Roboto Mono}'

If a file path is passed, the file's code is loaded then compiled to CSS, returning an object like above.

If a directory path is passed, SCSS files are searched for (recursively by default), each one's code is loaded then compiled, then an array of objects containing srcPath + code + srcMap + error is returned:

// Outputs paths to SCSS files in working directory + all nested directories
const compileResults = scssToCSS.compile('.');
compileResults.forEach(result => console.log(result.srcPath));

// Outputs compiled CSS from 2nd SCSS file if found, or `undefined` if not found
console.log(compileResults[1].code);

Options are boolean, passed as object properties. For example:

// Returns array of data objects where `.code` contains unminified CSS
scssToCSS.compile(inputDir, { minify: false });

Available parameters (and their default settings) are:

Name	Type	Desciption	Default value
recursive	Boolean	Recursively search for nested files if dir path passed.	true
verbose	Boolean	Show logging in console/terminal.	true
dotFolders	Boolean	Include dotfolders in file search.	false
minify	Boolean	Minify output CSS.	true
sourceMaps	Boolean	Generate CSS source maps.	true
ignoreFiles	Array	Files (by name) to exclude from compilation.	[]
comment	String	Header comment to prepend to compiled CSS. Separate by line using '\n'.	''

findSCSS(searchDir[, options])

Searches for all SCSS files within the searchDir string passed (useful for discovering what files compile() will process) and returns an array containing their filepaths.

Options are boolean, passed as object properties. For example:

// Search for SCSS files in exactly assets/scss
const searchResults = scssToCSS.findSCSS('assets/scss', { recursive: false });
console.log(searchResults);

/* sample output:

findSCSS() » Searching for SCSS files...
findSCSS() » Search complete! 2 files found.
findSCSS() » Check returned array.
[
  'E:\\js\\utils\\scss-to-css\assets\\scss\\foo.scss',
  'E:\\js\\utils\\scss-to-css\assets\\scss\\bar.scss'
]
*/

Available parameters (and their default settings) are:

Name	Type	Desciption	Default value
recursive	Boolean	Recursively search for nested files in searchDir passed.	true
verbose	Boolean	Show logging in console/terminal.	true
dotFolders	Boolean	Include dotfolders in file search.	false
ignoreFiles	Array	Files (by name) to exclude from search results.	[]
