using multiple .files() ?

[carpii]

I am trying to use two calls to file(), in the hope any elements present in one file will override those in the other

nconf.argv().env().file({file: 'nconf.json'}).file({file: 'host.json'});

If I util.inspect(nconf) it seems like the stores object is only able to hold one file store at a time, so nconf.json is being replaced entirely by host.json.

Is this a known issue, or have I misunderstood something?

+1 - I've just noticed this has been replacing parts of my config files.

My config files are:

default.json: Bare bones config, things that would otherwise need to be duplicated between all 'environment specific configs'

(production | stage | development).json: Environment specific configs, DB address etc

overrides.json: This is a special config file which can be updated, it is not included in the code repository like the other files.

I specify nconf.use('memory'); at the top of my code as I believed this would ensure no writing to any files...

How would you advise I go about this?

Temporary workaround:

    var localConfigPath = Path.resolve( '..my_path...', 'config'),

        defaultConfigPath = Path.resolve(localConfigPath, 'default.json'),
        defaultConfig = require( defaultConfigPath ),

        environmentConfigPath = Path.resolve(localConfigPath, nconf.get('environment') + '.json'),
        environmentConfig = require( environmentConfigPath ),

        remoteConfigPath = Path.resolve( '..my_path...', 'RemoteConfig.json'),
        remoteConfig = require( remoteConfigPath );


    nconf
        .add( 'remote', {
            type:'literal',
            store: remoteConfig
        })
        .add( nconf.get('environment'), {
            type:'literal',
            store: environmentConfig
        })
        .defaults({
            store: defaultConfig
        });

I think this is a duplicate of issue #97.

Shorter answer is that

var nconf = require('nconf');
nconf.file('overrides', 'overrides.json')
         .file('environment', development.json')
         .file('defaults', 'default.json');

should give you the effect you ask for.

Why is explained in my answer for #97.

I ran into a situation that the name of the store being "overrides" and "defaults" completely wipes out the stores for the call nconf.defaults() and nconf.overrides().

@vegar is this correct? I did the following to prevent that:

/**
 * Loads a given file based on the name.
 *
 * @param {string} appConfigDir the path to the file.
 * @param {string} fileName the name of the file.
 * @param {string} format is the format to be loaded.
 */
function _loadFile(appConfigDir, fileName, format) {
  var filePath = path.resolve(appConfigDir, fileName + "." + format);
  log.debug("Attempting to load the " + fileName + " file at " + filePath);

  if (format === "json") {
    nconf.file(fileName + "-store", filePath);

  } else {
    // load a yaml file using a custom formatter
    // https://gist.github.com/clarkdave/f31d92ca88d11ef5340c
    nconf.file({
      file: filePath + "-store",
      format: {
        parse: yaml.safeLoad,
        stringify: yaml.safeDump,
      }
    });
  }
}
