import-resolve

resolve @import statements in css preprocessors

What this does

What if you have some less or stylus files that you want to smash together into a master file, without compiling to css? Just use import-resolve and all your dreams will come true. All @import statements will be resolved and you'll be left with one file containing all your precious mixins, variables and declarations.

Example:

// foo.less 
@color_1: #444444;
@color_2: #555555;
 
// random-dir/bar.less 
.mixin () {
    font-size: 16px;
}
 
// main.less 
@import 'foo.less';
@import 'random-dir/bar.less';
 
#it-worked {
    color: green;
}

becomes...

@color_1: #444444;
@color_2: #555555;
 
.mixin () {
    font-size: 16px;
}
 
#it-worked {
    color: green;
}
 

Using import-resolve

npm install import-resolve

// some-node-thing.js
var importResolve = require('import-resolve');
 
// spits out a master dist file with all your wonderful stylesheet
// things concatenated
importResolve({
    "ext": "less",
    "pathToMain": "path/to/main.less",
    "output": "path/to/output.less"
});
 
// if you don't specify an output file, output accepts a callback parameter
// and passes the concatenated file text
var output = importResolve({
    "ext": "styl",
    "pathToMain": "path/to/main.styl"
}, function (output) {
    fs.writeFile('foo.styl', output, function (){
        console.log('did it myself.');
    });
});
 
// You can pass aliases if you have some files which have alias in your build process
importResolve({
    "ext": "less",
    "pathToMain": "path/to/main.less",
    "output": "path/to/output.less",
    "aliases": {
        "~myUniqueAlias": "path/to/unique/file.less"
    }
});
