spf13/viper

This system is a configuration management library that provides a unified interface for reading and writing configuration data in multiple formats, including JSON, YAML, TOML, and Dotenv. It supports pluggable encoders and decoders, allowing for custom file finding mechanisms and additional format support. The system also enables remote configuration retrieval from various backends like etcd, Firestore, and NATS. Additionally, it offers optional struct binding and customizable file search behaviors, all of which can be enabled via feature flags.

About this page

  • The description of this project is derived from its own commit history, not from its README.

  • Measured at commit 528f7416c4 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
