@burakbey/redacted v1.0.2

🔐 @burakbey/redacted

This is a library designed to safeguard sensitive data in your code. It provides a Redacted class that uses various techniques to prevent unintentional exposure of sensitive information. Even if an attempt is made to expose the data, it will appear as <redacted>.

📚 Credits

This library is inspired by concepts discussed in this YouTube video.

🚀 Installation

To install the package, use your preferred package manager. Here’s an example using pnpm:

pnpm add @burakbey/redacted

📝 Example Usage

The following example demonstrates usage in TypeScript. The library is also compatible with JavaScript.

import { Redacted } from '@burakbey/redacted';

// Unsafe Example:
// The value can be exposed if logged or written to a file without caution.
const password = 'super-secret-password';
console.log(password); // super-secret-password

// Safe Example:
// Use the `wrap` method to protect the value.
// The `unwrap` method explicitly reveals the original value, ensuring intentional access.
const password = Redacted.wrap('super-secret-password');
console.log(password); // <redacted>
console.log(Redacted.unwrap(password)); // super-secret-password

🔄 Change the Redacted Message

You can customize the default redacted message (<redacted>) to any string you prefer. To do this, set the environment variable REDACTED_MESSAGE to your desired value.

For example, if you set REDACTED_MESSAGE="[REDACTED]" and run the code, the output will reflect this change.

import { Redacted } from '@burakbey/redacted';

const password = Redacted.wrap('super-secret-password');
console.log(password); // [REDACTED]
