@gotocva/express-env

Overview

@gotocva/express-env is an Express middleware that allows secure and dynamic updates to the .env file of an Express project. It provides:

• A POST API to update environment variables.
• A GET API to retrieve all environment variables.
• Optional authentication for security.

Installation

Install the package using npm:

npm install @gotocva/express-env

Usage

1. Import and Use Middleware in Express App

const express = require('express');
const expressEnv = require('@gotocva/express-env');

const app = express();
app.use(express.json());

// Initialize middleware with authentication (optional)
app.use(expressEnv({ auth: { token: 'your_secure_token' } }));

app.listen(3000, () => console.log('Server running on port 3000'));

2. Update Environment Variables via API

Endpoint: POST /gotocva/env

Request Body:

{
  "key": "API_KEY",
  "value": "123456",
  "authToken": "your_secure_token"
}

Response:

{
  "success": true,
  "message": "Environment variable updated"
}

3. Retrieve All Environment Variables

Endpoint: GET /gotocva/env?authToken=auth_token

Response:

{
  "success": true,
  "env": {
    "API_KEY": "123456"
  }
}

Security Considerations

• Always enable authentication (authToken) to prevent unauthorized changes.
• Restrict access using middleware like cors or IP whitelisting.
