env-check

Validate environment variables before deployment by comparing actual environment keys against requirements listed in a .env.example file to catch misconfigurations and prevent startup failures.

Checking for missing dotenv variables in a CI pipeline involves scanning the current environment against .env.example to enforce the presence of required keys and flag missing values.

Startup failures from missing environment variables occur when required keys are absent or misconfigured, which can be prevented by validating environment configurations against .env.example.

Yes, .env.example can detect environment misconfigurations in staging by comparing actual environment variables to the template, identifying missing or incorrectly set values before runtime.

Environment validation works across development, staging, and production pipelines by enforcing required key presence and suggesting steps to obtain or set missing values before deployment.

Ensure all required environment keys exist by running a validation check that compares actual environment variables to the .env.example template and flags any missing keys.
