Client Management System: Feature Upgrade for Your App

Hey everyone! We're pumped to announce a major upgrade: a Client Management System for your todo-calendar app! This is a game-changer, folks. It's designed to help you stay super organized and on top of your game. Let's dive into the details, shall we?

Why Client Management?

Right now, the app rocks at managing tasks and calendars, but it's missing a key piece: the ability to connect those tasks and meetings to specific clients. With this new feature, you'll be able to:

  • Organize your work like a boss: Easily see everything related to a client in one place.
  • Get more context: Instantly understand the purpose of meetings and tasks.
  • Build a solid foundation: This is the first step towards powerful CRM features, like client history and activity tracking.
  • Support your business: Essential for any workflow that requires tracking client interactions.

What's the Plan?

We're building this feature using the same rock-solid architecture you're used to:

  • Database Layer: A brand new clients table in Supabase, complete with cool RLS policies.
  • Service Layer: Super-efficient Client CRUD operations in supabaseClientsService.ts.
  • State Management: We're sticking with React Context and a custom useClients hook.
  • UI Layer: List view, detail view, and form components, all with slick animations.
  • Integration: Seamlessly link clients to calendar events and tasks.

Tech Deep Dive

Alright, techies, let's get into the nitty-gritty!

Database Schema

We're creating a clients table in Supabase to store all the client info. Here's what it looks like:

-- supabase/migrations/20250113_create_clients_table.sql
CREATE TABLE clients (
  id UUID DEFAULT gen_random_uuid() PRIMARY KEY,
  user_id UUID REFERENCES auth.users(id),

  -- Identity
  name TEXT NOT NULL CHECK (char_length(name) >= 2 AND char_length(name) <= 100),
  email TEXT NOT NULL CHECK (char_length(email) >= 3 AND char_length(email) <= 255),
  phone TEXT CHECK (phone ~ '^[\\d\\s\\-\\+\${\}$]*{{content}}#39;),
  company TEXT CHECK (char_length(company) <= 100),

  -- Business context
  notes TEXT CHECK (char_length(notes) <= 1000),

  -- Metadata
  created_at TIMESTAMPTZ DEFAULT NOW() NOT NULL,
  updated_at TIMESTAMPTZ DEFAULT NOW() NOT NULL,

  -- Constraints
  CONSTRAINT unique_email_per_user UNIQUE(user_id, email)
);

-- Indexes for performance (matching tasks table pattern)
CREATE INDEX idx_clients_user_id ON clients(user_id);
CREATE INDEX idx_clients_email ON clients(email);

-- Enable RLS
ALTER TABLE clients ENABLE ROW LEVEL SECURITY;

-- RLS Policies (matching tasks table pattern)
CREATE POLICY "Users can view their own clients"
  ON clients FOR SELECT
  USING (user_id IS NULL OR user_id = auth.uid());

CREATE POLICY "Users can insert their own clients"
  ON clients FOR INSERT
  WITH CHECK (user_id IS NULL OR user_id = auth.uid());

CREATE POLICY "Users can update their own clients"
  ON clients FOR UPDATE
  USING (user_id IS NULL OR user_id = auth.uid());

CREATE POLICY "Users can delete their own clients"
  ON clients FOR DELETE
  USING (user_id IS NULL OR user_id = auth.uid());

-- Auto-update updated_at (using existing function pattern)
CREATE TRIGGER set_clients_updated_at
  BEFORE UPDATE ON clients
  FOR EACH ROW
  EXECUTE FUNCTION public.handle_updated_at();

We'll also add a relationship to the existing tasks table:

-- Add client_id to existing tasks table
ALTER TABLE tasks ADD COLUMN client_id UUID REFERENCES clients(id) ON DELETE SET NULL;
CREATE INDEX idx_tasks_client_id ON tasks(client_id);

ERD Diagram

Here's a visual of how everything connects:

erDiagram
    clients ||--o{ tasks : "has many"
    clients {
        uuid id PK
        uuid user_id FK
        text name
        text email
        text phone
        text company
        text notes
        timestamptz created_at
        timestamptz updated_at
    }
    tasks {
        uuid id PK
        uuid user_id FK
        uuid client_id FK
        text title
        text description
        boolean completed
        timestamptz scheduled_date
        text scheduled_time
        text end_time
        timestamptz created_at
        timestamptz updated_at
    }

TypeScript Types

We'll be adding some new types to src/lib/types.ts:

// Client interface (following Task interface pattern)
export interface Client {
  id: string;
  name: string;
  email: string;
  phone?: string;
  company?: string;
  notes?: string;
  createdAt: Date;
  updatedAt: Date;
}

// Helper function
export const getClientDisplayName = (client: Client): string => {
  return client.company ? `${client.name} (${client.company})` : client.name;
};

And updating src/lib/supabaseTypes.ts with generated types:

// To be generated after migration runs
export interface ClientDbRow {
  id: string;
  user_id: string | null;
  name: string;
  email: string;
  phone: string | null;
  company: string | null;
  notes: string | null;
  created_at: string;
  updated_at: string;
}

Validation Schemas

We'll use Zod to validate client data, with Hebrew error messages in src/lib/validationSchemas.ts:

// Client validation schema with Hebrew error messages
export const clientSchema = z.object({
  name: z.string()
    .min(2, '砖诐 讛诇拽讜讞 讞讬讬讘 诇讛讻讬诇 诇驻讞讜转 2 转讜讜讬诐')
    .max(100, '砖诐 讛诇拽讜讞 讗专讜讱 诪讚讬 (诪拽住讬诪讜诐 100 转讜讜讬诐)'),
  email: z.string()
    .email('讻转讜讘转 讗讬诪讬讬诇 诇讗 转拽讬谞讛')
    .min(1, '讗讬诪讬讬诇 讛讜讗 砖讚讛 讞讜讘讛'),
  phone: z.string()
    .regex(/^\\d\\s\\-\\+\${\}$\\*$/, '诪住驻专 讟诇驻讜谉 诇讗 转拽讬谉')
    .optional()
    .or(z.literal('')),
  company: z.string()
    .max(100, '砖诐 讛讞讘专讛 讗专讜讱 诪讚讬 (诪拽住讬诪讜诐 100 转讜讜讬诐)')
    .optional()
    .or(z.literal('')),
  notes: z.string()
    .max(1000, '讛讛注专讜转 讗专讜讻讜转 诪讚讬 (诪拽住讬诪讜诐 1000 转讜讜讬诐)')
    .optional()
    .or(z.literal('')),
});

export type ClientFormData = z.infer<typeof clientSchema>;

Service Layer

We're creating src/lib/supabaseClientsService.ts to handle all the CRUD operations, following the supabaseService.ts pattern:

import { supabase } from './supabaseClient';
import type { Client } from './types';
import type { ClientDbRow } from './supabaseTypes';

// Conversion functions (matching Task pattern from supabaseService.ts:16-51)
function dbRowToClient(row: ClientDbRow): Client {
  return {
    id: row.id,
    name: row.name,
    email: row.email,
    phone: row.phone || undefined,
    company: row.company || undefined,
    notes: row.notes || undefined,
    createdAt: new Date(row.created_at),
    updatedAt: new Date(row.updated_at),
  };
}

function clientToDbInsert(client: Omit<Client, 'id' | 'createdAt' | 'updatedAt'>) {
  return {
    name: client.name,
    email: client.email,
    phone: client.phone || null,
    company: client.company || null,
    notes: client.notes || null,
  };
}

function clientToDbUpdate(updates: Partial<Omit<Client, 'id' | 'createdAt' | 'updatedAt'>>) {
  return {
    ...(updates.name !== undefined && { name: updates.name }),
    ...(updates.email !== undefined && { email: updates.email }),
    ...(updates.phone !== undefined && { phone: updates.phone || null }),
    ...(updates.company !== undefined && { company: updates.company || null }),
    ...(updates.notes !== undefined && { notes: updates.notes || null }),
  };
}

// CRUD operations (matching pattern from supabaseService.ts:53-283)
export async function getAllClients(): Promise<Client[]> {
  try {
    const { data, error } = await supabase
      .from('clients')
      .select('*')
      .order('name', { ascending: true });

    if (error) throw error;
    return data.map(dbRowToClient);
  } catch (error) {
    console.error('[Supabase] Error fetching clients:', error);
    throw error;
  }
}

export async function createClient(clientData: Omit<Client, 'id' | 'createdAt' | 'updatedAt'>): Promise<Client> {
  try {
    const insertData = clientToDbInsert(clientData);
    const { data, error } = await supabase
      .from('clients')
      .insert([insertData])
      .select()
      .single();

    if (error) throw error;
    return dbRowToClient(data);
  } catch (error) {
    console.error('[Supabase] Error creating client:', error);
    throw error;
  }
}

export async function updateClient(id: string, updates: Partial<Omit<Client, 'id' | 'createdAt' | 'updatedAt'>>): Promise<Client> {
  try {
    const updateData = clientToDbUpdate(updates);
    const { data, error } = await supabase
      .from('clients')
      .update(updateData)
      .eq('id', id)
      .select()
      .single();

    if (error) throw error;
    return dbRowToClient(data);
  } catch (error) {
    console.error('[Supabase] Error updating client:', error);
    throw error;
  }
}

export async function deleteClient(id: string): Promise<void> {
  try {
    const { error } = await supabase
      .from('clients')
      .delete()
      .eq('id', id);

    if (error) throw error;
  } catch (error) {
    console.error('[Supabase] Error deleting client:', error);
    throw error;
  }
}

export async function searchClients(query: string): Promise<Client[]> {
  try {
    const { data, error } = await supabase
      .from('clients')
      .select('*')
      .or(`name.ilike.%${query}%,email.ilike.%${query}%,company.ilike.%${query}%`)
      .order('name', { ascending: true });

    if (error) throw error;
    return data.map(dbRowToClient);
  } catch (error) {
    console.error('[Supabase] Error searching clients:', error);
    throw error;
  }
}
