NPM Version Build Status

identify-resource

Resolve the file paths to js, css, and html dependencies.

Usage

resolve(sourcepath, id, options): resolve the path for id from sourcepath.

id can be an absolute filepath, relative filepath, "node_modules" reference, or "node_modules" file reference.

Available options include:

  • fileExtensions: hash of valid file extensions by type, used to resolve ids with missing file extension (default { js: 'js', 'json', css: 'css', html: 'html' })
  • sources: array of source directories (in addition to cwd and "node_modules") in which to search for files (default [])
$ npm install identify-resource

/projects/myproject/index.js

var bar = require('./bar')
  , boo = require('boo')
  , http = require('http');

/project/myproject/index.css

@import 'bar';

/projects/myproject/node_modules/boo/package.json

{
  "name": "boo",
  "version": "1.0.0",
  "main": "index.js"
}
var resolve = require('identify-resource').resolve;

// Resolve relative path
console.log(resolve('/projects/myproject/index.js', './bar')); 
//=> '/projects/myproject/bar.js'

// Resolve node_modules
console.log(resolve('/projects/myproject/index.js', 'boo')); 
//=> '/projects/myproject/node_modules/boo/index.js'

// Resolve native node modules
console.log(resolve('/projects/myproject/index.js', 'http')); 
//=> 'false'

// Resolve css
console.log(resolve('/projects/myproject/index.css', 'bar'));
//=> '/projects/myproject/bar.css'

Configuring the package.json browser field enables overriding default behaviour:

/projects/myproject/package.json

{
  "name": "myproject",
  "version": "1.0.0",
  "main": "index.js",
  "browser": {
    "http": "./lib/http.js"
  }
}
// Alias native module
console.log(resolve('/projects/myproject/index.js', 'http')); 
//=> '/projects/myproject/lib/http.js'

See here for more details on using the browser field.

identify(filepath, options): retrieve the id for filepath. Id's are resolved from the cwd or "node_modules", as appropriate.

var identify = require('identify-resouce').identify;

identify('/projects/myproject/bar.js'); //=> 'bar.js'
identify('/projects/myproject/boo/index.js'); //=> 'boo/index.js#1.0.0'
identify('/projects/myproject/bar.css'); //=> 'bar.css'

hasMultipleVersions(id): determine if more than one version of id exists in resolve cache

clearCache(): clear the resolve cache
