dotenv file is not loading environment variables

Question

I have .env file at root folder file

NODE_ENV=development
NODE_HOST=localhost
NODE_PORT=4000
NODE_HTTPS=false
DB_HOST=localhost
DB_USERNAME=user
DB         


        

Answer 1

Here is a single-line solution:

require('dotenv').config({ path: require('find-config')('.env') })

This will recurse parent directories until it finds a .env file to use.

You can also alternatively use this module called ckey inspired from one-liner above.

.env file from main directory.

# dotenv sample content
USER=sample@gmail.com
PASSWORD=iampassword123
API_KEY=1234567890

some js file from sub-directory

const ck = require('ckey');

const userName = ck.USER;     // sample@gmail.com
const password = ck.PASSWORD; // iampassword123
const apiKey   = ck.API_KEY;  // 1234567890

Answer 2

This solved the issue for me:

const path = require('path');
require('dotenv').config({
  path: path.resolve('config.env'),
});

Answer 3

One time I have got the same problem. Dotenv did not load .env file. I tried to fix this problem with a path config, to put .env file in a root folder, to put .env in the folder where the file is running and nothing helps me. Then I just trashed Node_modules folder, reinstall all dependencies and it works correctly

Answer 4

This solved my issues in Node v8.14.1:

const path = require('path')
require('dotenv').config({ path: path.resolve(__dirname, '../.env') })

Simply doing require('dotenv').config({path:__dirname+'/./../../.env'}) resulted in a location that resolved as /some/path/to/env/./../../.env

Answer 5

Adding a little nuance to the answer above - if you are invoking dotenv from a nested file, and your .env file is at the project root, the way you want to connect the dots is via the following:

require('dotenv').config({path:'relative/path/to/your/.env'})

Answer 6

How about use require('dotenv').config({path:__dirname+'/./../../.env'}) ?

Your problem seems to be the execution path.
