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.
-c, --copy Copy compiled CSS to clipboard instead of
writing to file if single source file is
processed.
-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 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. | []
