Database Seeding Instructions

This document explains how to seed the SIGAP database with sample data.

Prerequisites

• Node.js installed
• Required environment variables set (including database and Supabase credentials)
• Required data files in place (Excel files, GeoJSON, etc.)

Running the Seed Script

The main seeding script is designed to use both Snaplet and native Prisma operations to populate the database:

# Run the seed script
npx tsx seed.ts

What Gets Seeded

The seeding process runs the following operations in sequence:

1. Geographic data (cities, districts, geographic boundaries)
2. Police units (Polres and Polsek locations)
3. Permissions (Role-based access control)
4. Crime categories
5. Crime data (by unit and by type)
6. Crime incidents (by unit and by type)

Seeding Control

By default, the script will not reset your database. To enable database reset before seeding, uncomment the reset lines in seed.ts:

// Uncomment to reset database before seeding
// console.log("Resetting database...");
// await seed.$resetDatabase();
// console.log("Database reset complete.");

Customizing Seeds

Each seeder is contained in its own file under prisma/seeds/. To customize the seeding behavior, edit the corresponding file:

• geographic.ts - Seeds geographic data
• units.ts - Seeds police units
• permission.ts - Seeds permissions
• crime-category.ts - Seeds crime categories
• crimes.ts - Seeds crime data
• crime-incidents.ts - Seeds crime incidents by unit
• crime-incidents-cbt.ts - Seeds crime incidents by type

Performance Optimizations

The seeders include several optimizations to handle large datasets:

• Chunked batch operations
• Automatic retry with smaller batch sizes on failure
• Progress monitoring
• Throttling to prevent database overload
