PathMap

PathMap reduces redundancy when declaring path and configuration objects.

Installation

Navigate to your project and run the following command:

npm install --save-dev sfco-path-map

Usage

sfco-path-map exposes the PathMap constructor, which can be imported into your project as follows:

const PathMap = require( 'sfco-path-map' );

The PathMap constructor accepts a single object argument: paths. The paths object may have any number of keys, so long as the value of each key is either a string or an array of strings.

const PATHS = new PathMap( {
	src: './src',
	dist: './dist',
	exclude: [ './spec', './demo' ]
} );

Each key on the paths object is transferred to the new PathMap instance, and can be accessed using either . or [] notation. Each valid value within the paths object which does not include a placeholder will be transferred to the PathMap instance verbatim/without transformation.

console.log( PATHS.src ); // './src'
console.log( PATHS[ 'dist' ] ); // './dist'
console.log( PATHS.exclude ); // [ './spec', './demo' ]

Any substrings within the paths object that are surrounded by either __...__ or {{...}} characters are considered to be "placeholders". During instantiation, PathMap checks the placeholder value(s) against its own keys, and replaces them with the corresponding values if possible.

const PATHS = new PathMap( {
	src: './src',
	dist: './dist',
	styles: '__src__/styles',
	scripts: '{{src}}/scripts',
	vendor: [ '__styles__/vendor', '{{scripts}}/vendor' ]
} );

console.log( PATHS.styles ); // './src/styles'
console.log( PATHS.scripts ); // './src/scripts'
console.log( PATHS.vendor ); // [ './src/styles/vendor', './src/scripts/vendor' ]
