What are the best practices for using storage in Angular?

When using storage in Angular, it's important to consider performance, security, and data management. Here are some best practices:

1. Use Angular's built-in services for local storage and session storage.
2. Keep data minimal and avoid storing large objects.
3. Implement data expiration and cleanup strategies.
4. Secure sensitive data by encrypting it before storage.
5. Use observables to manage data changes effectively.

How can I secure sensitive data in local storage?

To secure sensitive data in local storage, you can:

1. Encrypt the data before storing it using libraries like CryptoJS.
2. Avoid storing sensitive information like passwords directly.
3. Use secure cookies or session storage for sensitive data when possible.

What libraries can help with data encryption?

Some popular libraries for data encryption in JavaScript include:

1. CryptoJS - a widely used library for various encryption algorithms.
2. jsEncrypt - for RSA encryption.
3. bcrypt.js - for hashing passwords securely.

Can you explain how to implement data expiration?

To implement data expiration in local storage, you can:

1. Store a timestamp along with your data.
2. Check the timestamp when retrieving data and compare it to the current time.
3. If the data is expired, remove it from storage and fetch fresh data.
