Production Best Practices: Security
Overview
The term “production” refers to the stage in the software lifecycle when an application or API is generally available to its end-users or consumers. In contrast, in the “development” stage, you’re still actively writing and testing code, and the application is not open to external access. The corresponding system environments are known as production and development environments, respectively.

Development and production environments are usually set up differently and have vastly different requirements. What’s fine in development may not be acceptable in production. For example, in a development environment you may want verbose logging of errors for debugging, while the same behavior can become a security concern in a production environment. And in development, you don’t need to worry about scalability, reliability, and performance, while those concerns become critical in production.

Helmet helps you secure your Express apps by setting various HTTP headers. It's not a silver bullet, but it can help!
