The discover command scans your source code for environment variable usage and suggests additions to your .preflight.yaml schema. This is the fastest way to sync your configuration with your code.

​
Usage

dotset preflight discover [options]

​
Options

OptionDescription
-s, --schema <path>Path to your existing schema file
--fixAutomatically add discovered variables to the schema

​
How it works

Preflight performs a static analysis of your source code to find common patterns of environment variable access:
  • JavaScript/TypeScript: process.env.VAR or process.env['VAR']
  • Python: os.environ.get("VAR") or os.getenv("VAR")
  • Go: os.Getenv("VAR")

​
Automatic Syncing

If you run with the --fix flag, Preflight will append any missing variables to your .preflight.yaml with a default type of string and a description indicating it was discovered in the code. 
dotset preflight discover --fix
[!TIP] Run discover --fix as part of your local pre-commit hook or developer setup script to ensure the environment schema never drifts from the codebase.
