Configuring your environment variables

Tell dotenv-validator how you expect your environment variables by commenting them in your .env.sample file.

VAR2=123 # format=int
VAR3=notrequired
VAR4=bob@bobloblaw.com # required,format=email

Formats

• int, integer
• float
• str, string (this is always true!)
• email (by mail.ParseAddress)
• url (by url.ParseRequestURI)
• anything else is treated as a regular expression!
