Building a Scalable Camp Management System with Next.js and Supabase: Essential Patterns and Examples

Are you developing a comprehensive web application for managing summer camp operations? Whether you’re working on scheduling, program management, staff coordination, or integrating external systems, having clear architectural patterns and code examples can significantly accelerate your progress. In this guide, we’ll explore key techniques and best practices for building such a system using Next.js, Supabase, and related tools, with practical snippets to help you implement complex features confidently.

1. Managing Program Data and Workflows

Creating, updating, and approving camp programs and requisitions requires reliable data handling and robust workflows.

Form Handling and Data Persistence

Use React Hook Form combined with Zod for validation, and Supabase’s client library for database interaction:

“`tsx
import { useForm } from ‘react-hook-form’;
import { z } from ‘zod’;
import { supabase } from ‘../lib/supabaseClient’;

const programSchema = z.object({
name: z.string().min(1),
description: z.string().optional(),
// add other fields as needed
});

function CreateProgramForm() {
const { register, handleSubmit, errors } = useForm({
resolver: zodResolver(programSchema),
});

const onSubmit = async (data) => {
const { data: inserted, error } = await supabase
.from(‘programs’)
.insert([data]);
if (error) console.error(error);
else console.log(‘Program created:’, inserted);
};

return (

);
}
“`

Implementing Approval Workflows with Row-Level Security (RLS)

Define your schema with an approvals table and proper RLS policies:

``sql
-- Example:programs` table
CREATE TABLE programs (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
name TEXT NOT NULL,
description TEXT,
status TEXT DEFAULT ‘draft’, — e.g., ‘draft’, ‘pending’, ‘approved’
created_by uuid REFERENCES auth.users(id),
— other fields
);

— RLS policy granting access only to creators or
