@est/errcode

The TS mirror of the errcode crate. Normative source: conformance/errcode/cases.json; the Rust crate passes the same fixture. See packages/errcode/SPEC.md for REQ anchors and oracles.

import { errcode, makeProblem, display } from "@est/errcode";

errcode("NotFound").status; // 404
display("NotFound"); // "Not Found (404)"
makeProblem("Validation", { detail: "name is required" });
// { type: "https://httpstatuses.com/422", title: "Validation Error", status: 422, detail: "..." }
