MKP CORE SDK

This repo host the core of a secure, bidirectional communication system between host applications and client applications (running inside iframes). The project consists of:

• Core SDK – A lightweight, type-safe communication layer that uses the browser’s postMessage API to facilitate secure messaging between different window contexts. It handles low-level details such as secure handshakes, request/response patterns, event pub/sub, and origin validation. Consumed by Host SDK and Client SDK to abstract the communication layer

Structure

The repository is organized as follows:

/root
├── package.json          // Root configuration, workspaces, and scripts
├── core              // Core SDK (communication layer)
└── docs                  // Additional documentation and project guides

Getting Started

Prerequisites

• Node.js
• npm

Installation

Install dependencies from the root:

npm install

This installs all dependencies across the packages and sets up the workspaces.

Commands

Below are the main monorepo commands defined in the root package.json:

• Build Package
  Build every package (transpiling TypeScript, etc.):

  npm run build

• Clean Package
  Remove build artifacts (e.g., dist directories):

  npm run clean

• Lint All Packages
  Run ESLint checks:

  npm run lint

• Run Tests
  Execute test suites:

  npm run test

High-Level SDK Overview

Core SDK

• Purpose: Acts as the backbone for secure communication. It abstracts all low-level postMessage handling and exposes a uniform, type-safe API.
• Key Features: Secure handshake, request/response pattern, event pub/sub system, and origin validation.
