ShopDB - Claude Code Instructions

Project Overview

ShopDB is a Classic ASP/VBScript web application for managing manufacturing shop floor infrastructure at GE Aerospace. It tracks machines, PCs, printers, and network devices.

Technology Stack

• Backend: Classic ASP (VBScript)
• Database: MySQL 5.6
• Frontend: Bootstrap 4.6, jQuery, DataTables
• Server: IIS on Windows VM (192.168.122.151:8080)
• Version Control: Gitea (localhost:3000)

Key Architecture

Database Schema (Phase 2 - Current)

machines table (unified)
├── Equipment (machinetypeid 1-24, pctypeid IS NULL)
├── PCs (machinetypeid 33-35, pctypeid IS NOT NULL)
└── Network Devices (machinetypeid 16-20)

printers table (separate)
communications table (all network interfaces)
machinerelationships table (PC↔equipment links)

Key Queries

-- All PCs
SELECT * FROM machines WHERE pctypeid IS NOT NULL;

-- All Equipment
SELECT * FROM machines WHERE pctypeid IS NULL AND machinetypeid < 16;

-- Network devices
SELECT * FROM machines WHERE machinetypeid IN (16,17,18,19,20);

Log Locations

IIS Logs (Windows VM): /home/camp/projects/windows/logs/shopdb/

• Format: ex[YYMMDD].log (e.g., ex251201.log for Dec 1, 2025)
• These are synced from the Windows VM via Samba share
• Contains HTTP request logs with status codes and error messages

API Logs: Check logs/ folder in shopdb directory on IIS

Coding Standards

ASP/VBScript

1. Always use parameterized queries - Never concatenate user input into SQL
2. Use HTMLEncode for output - Prevent XSS attacks
3. Convert text fields to strings - Use & "" to avoid type mismatch errors
4. Use Option Explicit - Declare all variables

Example Safe Query

Dim cmd, rs
Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = objConn
cmd.CommandText = "SELECT * FROM machines WHERE machineid = ?"
cmd.Parameters.Append cmd.CreateParameter("@id", 3, 1, , machineId)
Set rs = cmd.Execute()

Example Safe Output

' Always convert to string and encode
Dim hostname
hostname = ""
If NOT IsNull(rs("hostname")) Then hostname = rs("hostname") & ""
Response.Write(Server.HTMLEncode(hostname))

Common Tasks

Reading Files

• Main pages are in project root (*.asp)
• Includes are in /includes/
• Check docs/ for documentation

Making Changes

1. Read the file first
2. Use parameterized queries for any SQL
3. Test on dev server (192.168.122.151:8080)
4. Check IIS logs for errors

Database Access

docker exec -it dev-mysql mysql -u root -prootpassword shopdb

Important Notes

VBScript Limitations

• No IIf() function - use If-Then-Else instead
• No Try-Catch - use On Error Resume Next carefully
• Strings are 1-indexed, not 0-indexed

Column Name Gotchas

• address not ipaddress in communications table
• machinenotes not notes in machines table
• machineid not pcid for PCs in machines table

PC Identification

PCs are in the machines table, identified by:

• pctypeid IS NOT NULL
• machinetypeid IN (33, 34, 35)

API Endpoints

Action	Method	Description
updateCompleteAsset	POST	PC data collection
getDashboardData	GET	Health check
