rcloader

For build system plugins that need to fetch relative config files (like .jshintrc).

  • Find the closest config file (like .jshintrc) relative to the file you are linting
  • Lookups are cahched to limit IO operations
  • Accepts input directly from plugin consumers to
    • specifiy a file that should always be used
    • specify overrides
    • disable file lookup
npm install rcloader

This plugin was written to specifcally address this issue for a couple gulp plugins.

var RcLoader = require('rcloader');
var map = require('map-stream');
 
module.exports = function MyGulpPlugin(options) {
  var rcLoader = new RcFinder('.configfilename', options);
 
  return map(function (filecb) {
    // get the options for this file specifically 
    rcLoader.for(file.path, function (errfileOpts) {
      // do something cool 
 
      // send the file along 
      cb(null, file);
    });
  });
};

If you would rather, just skip the callback and it will run synchronously.

var fileOpts = rcLoader.for(file.path, options);

The second argument to the RcFinder constructor should be the options that plugin consumers define, and they can take can take a few different forms.

If the user specifies a string, it is used as a path to the only config file that they care about. Calling rcLoader.for(path) will always return a copy of the config file at that path.

If the user specifies an object, the following keys will be striped from it and the remaining values will override values found in the config files.

  • lookup, Boolean, Find the closest config file each time .for() is called. default is true, unless config is a path.
