Get the file associated with a dependency/partial's path

npm install --save filing-cabinet

var cabinet = require('filing-cabinet');

var result = cabinet({
  partial: 'somePartialPath',
  directory: 'path/to/all/files',
  filename: 'path/to/parent/file',
  ast: {}, // an optional AST representation of `filename`
  // Only for JavaScript files
  config: 'path/to/requirejs/config',
  webpackConfig: 'path/to/webpack/config',
  nodeModulesConfig: {
    entry: 'module'
  },
  tsConfig: 'path/to/typescript/config'
});

console.log(result); // /absolute/path/to/somePartialPath

• partial: the dependency path
• This could be in any of the registered languages
• directory: the path to all files
• filename: the path to the file containing the partial
• ast: (optional) the parsed AST for filename.
• Useful optimization for avoiding a parse of filename
• config: (optional) requirejs config for resolving aliased JavaScript modules
• webpackConfig: (optional) webpack config for resolving aliased JavaScript modules
• nodeModulesConfig: (optional) config for resolving entry file for node_modules. This value overrides the main attribute in the package.json file; used in conjunction with the packageFilter of the resolve package.
• tsConfig: (optional) path to a typescript configuration. Could also be an object representing a pre-parsed typescript config.
• noTypeDefinitions: (optional) For typescript files, whether to prefer *.js over *.d.ts.

By default, filing-cabinet provides support for the following languages:

• JavaScript: CommonJS, AMD, ES6
• TypeScript
• CSS Preprocessors: Sass (.scss and .sass), Stylus (.styl), and Less (.less)

You can register resolvers for new languages via cabinet.register(extension, resolver).

• extension: the extension of the file that should use the custom resolver (ex: '.py', '.php')
• resolver: a function that accepts the following (ordered) arguments that were given to cabinet:
  • partial
  • filename
  • directory
  • config

For examples of resolver implementations, take a look at the default language resolvers:

• sass-lookup
• stylus-lookup
• amdLookup

If a given extension does not have a registered resolver, cabinet will use a generic file resolver which is basically require('path').join with a bit of extension defaulting logic.

• Requires a global install npm install -g filing-cabinet
