Appwrite Service Layer Pattern

When to use this skill

• Before writing database logic in a component.
• When a database query needs to be reused across multiple pages or actions.

Folder Structure

• services/tours.ts
• services/bookings.ts
• services/auth.ts

Example Pattern

import { databases, DATABASE_ID, COLLECTIONS } from '@/lib/appwrite';
import { Query } from 'appwrite';
import { Tour } from '@/types';

export const TourService = {
    async getAll(limit = 10) {
        return await databases.listDocuments<Tour>(
            DATABASE_ID,
            COLLECTIONS.TOURS,
            [Query.limit(limit), Query.orderDesc('$createdAt')]
        );
    },
    async getById(id: string) {
        return await databases.getDocument<Tour>(DATABASE_ID, COLLECTIONS.TOURS, id);
    }
};

Instructions

• Abstraction: Components should call TourService.getAll() rather than the Appwrite SDK directly.
• Error Handling: Catch errors in the service or re-throw them with descriptive messages.
