@condux/core

The isomorphic engine at the heart of every JavaScript Condux SDK. It emits the Sentry "store" wire shape and delivers it over a resilient, never-throwing transport, using only fetch / crypto / URL so it runs unchanged in Node, browsers and edge runtimes.

You usually do not install this directly. Pick the SDK for your runtime, which re-exports this core:

• @condux/node — Node services.
• @condux/browser — browsers, with automatic global error capture.
• @condux/edge — Cloudflare Workers / Vercel Edge / Deno, with a wrapFetch boundary.
• @condux/nextjs — the Next.js App Router adapter over the three above.

API

import { init, captureException, captureMessage, Level } from "@condux/core";

init({ dsn: "https://<publicKey>@relay.condux.ai/<projectId>" });

captureException(new Error("boom"));
captureMessage("checkout latency degraded", Level.Warning);

Both capture* calls return a Promise<SendResult> and never throw; a failed delivery reports { ok: false } rather than crashing the host app.

Layout

Split by responsibility to keep files small: types (options + Level + SendResult), dsn, transport (retry/backoff), stack (frame parsing + normalizeFramePath), client (the capture entry points). Built with plain tsc; tested on the .ts source under Node's type-stripping.
