NODE-ENV-FILE 

Parse and load environment files (containing ENV variable exports) into Node.js environment, i.e. process.env.

Example

.env

``bash
# some env variables

FOO=foo1
BAR=bar1
BAZ=1
QUX=
# QUUX=
`

.env2

`bash
# some env variables using exports syntax

exports FOO=foo2
exports BAR=bar2
exports BAZ=2
exports QUX=
# exports QUUX=

`

index.js

`javascript
var assert = require('assert');
var env = require('node-env-file');

process.env.FOO = "defaultfoo";

// Load any undefined ENV variables form a specified file.
env(__dirname + '/.env');
assert.equal(process.env.FOO, "defaultfoo");
assert.equal(process.env.BAR, "bar1");
assert.equal(process.env.BAZ, "1");
assert.equal(process.env.QUX, "");
assert.equal(process.env.QUUX, undefined);

// Load another ENV file - and overwrite any defined ENV variables.
env(__dirname + '/.env2', {overwrite: true});
assert.equal(process.env.FOO, "foo2");
assert.equal(process.env.BAR, "bar2");
assert.equal(process.env.BAZ, "2");
assert.equal(process.env.QUX, "");
assert.equal(process.env.QUUX, undefined);
