Effect-TS Resource Management

Overview

Manage resource lifecycles using Scope and acquireRelease to guarantee cleanup. Cleanup always runs, even if the program fails, throws, or is interrupted.

When to Use

• Symptoms: Resource leaks (hanging connections), manual try/finally blocks, complex cleanup logic.
• Triggers: Opening files, connecting to databases, starting servers, acquiring locks.
• When NOT to use: For simple data transformations or values that don't require explicit closing/release.

Core Pattern

Manual try/finally is error-prone in Effect because it bypasses interruption handling.
