Node.js Question

Can't find config directory in JS file

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
WARNING: To disable this warning set SUPPRESS_NO_CONFIG_WARNING in the environment.
/home/rc-user/node/node_modules/config/lib/config.js:181
throw new Error('Configuration property "' + property + '" is not defined');
^

Error: Configuration property "database.host" is not defined

at Module.runMain (module.js:607:10)
at run (bootstrap_node.js:420:7)
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" : {
"apnkey" : "something",
"apnkeyid" : "something",
"apnteamid" : "something",
"googleAPI" : "something",
"authorization" : "something",
"push_app_id" : "something"
}
}


This is the config file (default.json) in config directory.

Answer Source

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
