TypeScript Models and Interfaces

When to use this skill

• •When defining the data structure for a new Appwrite collection.
• •When creating props for components that data-fetch.
• •To avoid using any across the codebase.

Workflow

• • Export interfaces from a central types/ directory.
• • Include standard Appwrite fields ($id, $createdAt, $updatedAt, $permissions).
• • Use Enums for fields with fixed values (e.g., BookingStatus).

Example Template

import { Models } from 'appwrite';

export interface Tour extends Models.Document {
    title: string;
    description: string;
    price: number;
    location: string;
    images: string[];
    rating: number;
    availableDates: string[]; // ISO Strings
}

export type BookingStatus = 'pending' | 'confirmed' | 'cancelled';

export interface Booking extends Models.Document {
    userId: string;
    tourId: string;
    status: BookingStatus;
    totalPrice: number;
}

Instructions

• •Generics: Use these interfaces with Appwrite SDK methods: databases.listDocuments<Tour>(...).
• •Readonly: Mark fields as readonly if they shouldn't be mutated by the frontend.
