get-module-file

This module is a utility for finding the path to a file within an installed module.

Example

Let's assume you have the following project structure:

-- my_module
  |
  |
  -- node_modules
  | |
  | |
  | -- style_mod
  |   |
  |   |
  |   -- style.css
  |
  |
  -- lib
    |
    |
    -- foo.js

For some reason your foo.js needs to read the contents of style.css. But a module of assets usually cannot be required (e.g. concise.css). On top of that, the node_modules directory may not be where you think if your module is installed in another module; with npm3 the style_mod module could be in the parent module's node_modules.

Solution: use get-file-module to find the file:

const gfm = require('get-file-module');
gfm.future(__dirname, 'style_mod', '/style.css')
  .then(function(filePath) {
    // read the file and do whatever is you need to do
  });

API

async(startDir, moduleName, filePath, callback)

  • startDir: the directory from which to start looking for node_modules
  • moduleName: the name of the module that contains the file you want
  • filePath: relative path to the file from the module directory
  • callback: a function with parameters error and resolvedPath.

sync(startDir, moduleName, filePath)

  • startDir: the directory from which to start looking for node_modules
  • moduleName: the name of the module that contains the file you want
  • filePath: relative path to the file from the module directory
  • returns: false on error (i.e. can't find file) or the resolved file path

future(startDir, moduleName, filePath)

  • startDir: the directory from which to start looking for node_modules
  • moduleName: the name of the module that contains the file you want
  • filePath: relative path to the file from the module directory
  • returns: a Promise that has the resolved file path on resolution and an Error on rejection (couldn't find the file)
