Implementation Plan - Publish @scrapshield/node The goal is to prepare and publish the @scrapshield/node package to npm. This package contains the backend middleware for ScrapShield integration.

Proposed Changes SDK Directory [NEW] package.json Create package.json with the following details: Name: @scrapshield/node Version: 1.0.0 Description: "ScrapShield Node.js Middleware" Main: index.js Keywords: ["scrapshield", "middleware", "security", "scraping-protection"] Author: "ScrapShield" License: "ISC" (or strictly private if not intended for public yet, but user implied public install) Verification Plan Automated Run npm pack in d:/Code/React/ScrapShield_ai/scrapshield_ai_backend/sdk/node to generate a tarball and verify its contents. Run npm whoami to check if the user is logged in. Manual User will need to approve the npm publish command.

roposed Changes chat_system_backend [MODIFY] package.json Add "name": "chat-system-backend" Add "version": "1.0.0" Add "description": "Backend for Chat System" (optional but good practice) Add "main": "server.js" (implicitly used by nodemon but good to refer) Verification Plan Automated Tests Run npm install to ensure the package usage is valid. Run npm pkg fix to let npm dry-run fix any anomalies (optional). (If user confirms publish intent) Run npm publish --dry-run to verify it would work. Manual Verification Check package.json content.
