## Golden config for golangci-lint v1.59.0

# This is the best config for golangci-lint based on my experience and opinion.
# It is very strict, but not extremely strict.
# Feel free to adapt and change it for your needs.

run:
  # Timeout for analysis, e.g. 30s, 5m.
  # Default: 1m
  timeout: 3m

# This file contains only configs which differ from defaults.
# All possible options can be found here https://github.com/golangci/golangci-lint/blob/master/.golangci.reference.yml
