turborepo-env

Purpose

Environment variable filtering and hashing for tasks. Filters environment variables based on task configuration and produces deterministic hashes for cache keys.

Architecture

Process environment
    └── turborepo-env
        ├── Filter by patterns (include/exclude)
        ├── Apply strict/loose mode
        └── Hash for cache key

Filtering modes:

• Strict: Only explicitly listed env vars
• Loose: All process env vars available

Notes

Environment variables are a key cache input. This crate ensures deterministic hashing (sorted, consistent format) and proper filtering based on turbo.json configuration.
