dotenv-with-expand

This is a drop-in replacement for dotenv but with preloaded dotenv-expand functionality.

Install

``bash


with npm

npm install dotenv-with-expand

or with Yarn

yarn add dotenv-with-expand

or with pnpm

pnpm install dotenv-with-expand
`

Usage

As early as possible in your application, require and configure dotenv.

`javascript
require('dotenv-with-expand').config();
`

Create a .env file in the root directory of your project.
Add environment-specific variables on new lines in the form of NAME=VALUE.
For example:

`dosini
DB_HOST=localhost
DB_USER=root
DB_PASS=s1mpl3
DB_URI="${DB_USER}:${DB_PASS}@${DB_HOST}"
`

process.env now has the keys and values you defined in your .env file.

See dotenv-expand for more substitution examples.

`javascript
const db = require('db');
db.connect({
host: process.env.DB_HOST,
username: process.env.DB_USER,
password: process.env.DB_PASS,
});
console.log(connected to ${process.env.DB_URI});
`

$3

You can use the --require (-r) command line option to preload dotenv. By doing this, you do not need to require and load dotenv in your application code. This is the preferred approach when using import instead of require.

`bash
$ node -r dotenv-with-expand/config your_script.js
`

The configuration options below are supported as command line arguments in the format dotenv_config_=value

`bash
$ node -r dotenv-with-expand/config your_script.js dotenv_config_path=/custom/path/to/your/env/vars
`

Additionally, you can use environment variables to set configuration options. Command line arguments will precede these.

`bash
$ DOTENV_CONFIG_=value node -r dotenv-with-expand/config your_script.js
`

`bash
$ DOTENV_CONFIG_ENCODING=latin1 node -r dotenv-with-expand/config your_script.js dotenv_config_path=/custom/path/to/.env
`

Config

config will read your .env file, parse the contents, assign it to
process.env,
and return an Object with a parsed key containing the loaded content or an error` key if it failed.

Please refer to dotenv for more information.

Parse

The engine which parses the contents of your file containing environment
variables is available to use. It accepts a String or Buffer and will return
an Object with the parsed keys and values.

Please refer to dotenv for more information.
