@runtimevault/core

Framework-agnostic RuntimeVault SDK. Captures the complete runtime state at the moment of failure so you can replay production bugs locally.

Install

Works the same on macOS, Windows, and Linux (any modern Node / package manager). The browser bundle also runs in Chrome, Firefox, Safari, and Edge.

npm install @runtimevault/core
# or
pnpm add @runtimevault/core
# or
yarn add @runtimevault/core

Quick start

import { RuntimeVault } from '@runtimevault/core';

RuntimeVault.init({
  apiKey: 'rv_live_...',
  environment: 'production',
  // Optional: capture only a fraction of errors (0–1). Default 1 = all.
  // sampleRate: 0.1,
});

That is enough for automatic capture on window.onerror and unhandled promise rejections.

Features

• Call stack, variables, network buffer, console history, DOM, and environment
• Privacy masking before data leaves the browser
• Gzip compression and low overhead capture path
• sampleRate — drop a fraction of captures client-side to control volume
• Pluggable transports (cloud ingest or local)

Manual capture

import { RuntimeVault } from '@runtimevault/core';

try {
  risky();
} catch (error) {
  RuntimeVault.captureException(error);
  throw error;
}

Replay

npx @runtimevault/cli login
npx @runtimevault/cli replay <snapshot-id>
