To handle async errors in TypeScript without silent failures, define explicit typed errors and establish safe async boundaries. Apply custom error classes and Result-style returns across service layers and API adapters to capture expected and unexpected failures with clear context.

The best way to implement custom error classes in TypeScript is to define them with specific codes, status information, and context. This approach allows targeted try/catch blocks to differentiate between expected recoverable failures and unexpected issues across modules.

Use Result-style returns for recoverable failures to enforce explicit error checking at compile time, while applying targeted try/catch blocks for unexpected failures. Combining both patterns across service layers and repositories prevents silent failures and simplifies debugging.

Structure error handling across TypeScript service layers and API adapters by applying consistent typed error patterns. Implement custom error classes with context and codes, use Result-style returns for recoverable failures, and wrap boundaries in targeted try/catch blocks.

You need typed error handling patterns in TypeScript when reducing silent failures and simplifying debugging across async boundaries. Explicit typed errors are essential when managing complex modules like service layers, repositories, and API adapters where unexpected failures occur.

TypeScript may not catch async exceptions in service layers due to untyped or unbounded async boundaries. Resolve this by implementing safe async boundaries, applying targeted try/catch blocks, and returning explicit Result-style objects to capture failure context and codes.
