tsentials-http

What problem does it solve?

It eliminates repetitive error handling in TypeScript HTTP calls by returning a Result<T> for both success and failure responses instead of throwing exceptions or forcing manual try/catch logic.

Core Features & Use Cases

• fetchResult wrapper: Perform get/post/put/patch/delete requests and receive Promise<Result<T>> where 2xx becomes success and 4xx/5xx becomes failure.
• RequestBuilder fluent API: Build headers, query parameters, and JSON or raw bodies with a terminal .send<T>() call for typed responses.
• Error mapping and parsing: Convert HTTP status codes into AppError via httpStatusToError and extract human-readable details from RFC 9457 ProblemDetails via extractErrorDescription.

Quick Start

Use tsentials-http to call an endpoint and handle errors via Result<T> rather than exceptions by writing a single RequestBuilder flow that ends with .send<User>().
