HTTPS is enforced, and secure HTTP headers (HSTS, CSP) are enabled.

The term "production settings" often appears in user interfaces as a specific button or a group of configuration options, but its meaning varies significantly by context. In manufacturing, it refers to the machine-level parameters that define how a product is made. In software engineering, it describes the unique configuration files used to optimize an app's performance in a live environment. In data science, it is the challenging act of deploying a machine learning model into a real-world application.

Deploying software to a production environment is the ultimate test of an engineering team’s discipline. In a local development environment, shortcuts are acceptable; in production, those same shortcuts trigger outages, data breaches, and financial loss.

Shifting from traditional, hierarchical, hands-on production to high-tech environments can encounter resistance from long-term staff. HTTPS is enforced, and secure HTTP headers (HSTS,

Every production environment should have a "Runbook" or documentation that lists every required configuration value, its source, and its expected format.

Provide for software production environments.

For production, .env files are an absolute anti-pattern. You must integrate a dedicated secrets management solution. Several excellent options exist for different needs:

Layered configuration loading provides a robust architectural foundation. A base configuration file defines settings structurally identical across all environments. Environment‑specific JSON files overwrite colliding keys based on the runtime environment variable. User secrets provide a security buffer for local development, preventing secrets from ever touching the Git repository. Environment variables serve as the ultimate override, loaded last and capable of overwriting even production JSON files. The golden rule is never to commit production API keys, passwords, or client secrets to any configuration file in source control. If a file is in source control, it is potentially public.

Never store API keys, database passwords, or URLs in your source code.
