This is my directory structure:

/node
. /config
  . default.js
. node_modules
. /controllers
  . myfile.js
  . other files
. app.js

And here's some of code written in myfile.js

const express = require('express');
const app = express();
const mysql = require('mysql');
const path = require('path');
const config = require('config');
const bodyParser = require('body-parser');
const moment = require('moment');
app.use(bodyParser.json({type: '*/*'}));
var client;
const redis = require("redis");
client = redis.createClient();

client.on("error", function (err) {
    console.log("Error " + err);
});

const connectionPool = mysql.createPool({
    host: config.get('database.host'),
    user: config.get('database.user'),
    password: config.get('database.password'),
    database: config.get('database.dbname'),
    connectionLimit: 2
});

function selectUpdatedData() {

    connectionPool.query("SELECT * FROM rc_devices_notifications", function (err, rows, fields) {
        //DO STUFF
        process.exit();
    });
}

selectUpdatedData();

Now, when I run this file using node myfile.js, I see following error:

WARNING: No configurations found in configuration directory:/home/rc-user/node/controllers/config

    at startup (bootstrap_node.js:139:9)

However, when I run app.js (my server, that too uses config), it shows no error. It gets config files.

What am I doing wrong?

EDIT: The default.json file:

{
  "database" : {
    "host" :"something",
    "user" : "something",
    "password" : "something",
    "dbname" : "something"
  },
  "parameters" : {

• javascript
• node.js
• path
• directory
• config

• 1 can you post the config file also, maybe there is some problem ? – Alexandru Olaru Commented Aug 28, 2017 at 7:02
• Updated. Please check. – Vikas Commented Aug 28, 2017 at 7:05
• please try running app from the root folder like: node controllers/myfile.js – Raghav Garg Commented Aug 28, 2017 at 7:07
• The config seems ok, and the configuration also, maybe you are exporting a different environment like export NODE_ENV=production or other and it can't find your configuration... – Alexandru Olaru Commented Aug 28, 2017 at 7:08

As you have in error

No configurations found in configuration directory:/home/rc-user/node/controllers/config

Since you are starting your app from subfolder, the config package is finding the config directory from that relative path.

Please use

node controllers/myfile.js

So that config will find the config directory from the root of the project.

You can use environment variable NODE_CONFIG_DIR for setting custom config directory path. Read more about NODE_CONFIG_DIR.

The default NODE_CONFIG_DIR is the /config directory under the current working directory
