Like any kind of apps, JavaScript apps also have to be written well.

Otherwise, we run into all kinds of issues later on.

In this article, we’ll look at some best practices we should follow when writing Node apps.

Generating Random Strings Using Node.js

We can generate random strings with the cryptoRandomBytes method.

Other methods might not be as random as we think.

And this makes applications vulnerable to cryptographic attacks.

Authentication

We should use multi-factor authentication for important services and accounts.

Passwords should be rotated frequently, including SSH keys.

Strong password policies should be applied everywhere.

Don’t ship apps with any default credentials.

Only standard authentication methods like OAuth, OpenID, etc should be used.

Basic auth is insecure so we shouldn’t use it.

Auth endpoints should have rate-limiting so attackers can’t use brute force attacks to attack our app.

When there are login failures, we shouldn’t let users know that username or password validation failed.

The error message should be generic to avoid guessing.

Using a centralized user management system is also a good idea to avoid multiple accounts.

Access Control

The principle of least privilege should be followed.

This means the least amount of power should be granted to a user for them to do their work.
