How to define env file mail form

An .env file is a common way to store environment variables for a project. Here's a basic outline of how to define an .env file for a mail form:

What is an .env file?

An .env file is a plain text file that contains key-value pairs, where each line represents an environment variable. The file is used to store sensitive information, such as API keys, database credentials, and other settings that should not be committed to version control.

How to define an .env file for a mail form

To define an .env file for a mail form, you'll need to specify the following variables:

MAIL_HOST: The hostname or IP address of your mail server.
MAIL_PORT: The port number used by your mail server.
MAIL_USERNAME: The username used to authenticate with your mail server.
MAIL_PASSWORD: The password used to authenticate with your mail server.
MAIL_FROM: The email address that will be used as the sender's address.
MAIL_TO: The email address that will receive the mail form submissions.

Here's an example .env file:

MAIL_HOST=smtp.example.com
MAIL_PORT=587
MAIL_USERNAME=myusername
MAIL_PASSWORD=mypassword
[email protected]
[email protected]

How to use the .env file in your code

To use the .env file in your code, you'll need to load the variables into your application. The exact method will depend on the programming language and framework you're using.

For example, in PHP using the dotenv package:

<?php
require 'vendor/autoload.php';

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

$mailHost = $_ENV['MAIL_HOST'];
$mailPort = $_ENV['MAIL_PORT'];
$mailUsername = $_ENV['MAIL_USERNAME'];
$mailPassword = $_ENV['MAIL_PASSWORD'];
$mailFrom = $_ENV['MAIL_FROM'];
$mailTo = $_ENV['MAIL_TO'];

In Node.js using the dotenv package:

const dotenv = require('dotenv');
const env = dotenv.config();

const mailHost = process.env.MAIL_HOST;
const mailPort = process.env.MAIL_PORT;
const mailUsername = process.env.MAIL_USERNAME;
const mailPassword = process.env.MAIL_PASSWORD;
const mailFrom = process.env.MAIL_FROM;
const mailTo = process.env.MAIL_TO;

Remember to never commit your .env file to version control, as it contains sensitive information. Instead, add it to your .gitignore file to exclude it from version control.
