mock-data

Mock Data Generator Skill

Creates typed mock data files following project patterns.

File Pattern

src/​data/​mock-{feature}.ts

Template Structure

// src/​data/​mock-{feature}.ts

export interface {Feature}Data {
    id: string;
    name: string;
    // Add fields based on requirements
}

export const mock{Feature}Data: {Feature}Data = {
    id: "1",
    name: "Example",
};

// For arrays:
export const mock{Feature}List: {Feature}Data[] = [
    { id: "1", name: "Item 1" },
    { id: "2", name: "Item 2" },
];

Conventions

1. Filename: kebab-case with mock- prefix
2. Named exports: Both interface and data
3. Type-first: Define interface before data
4. Realistic data: Use meaningful values, not "test123"

Examples

See these files for reference patterns:

• src/​data/​mock-order.ts
• src/​data/​mock-project.ts
• src/​data/​mock-unmatched-items.ts

Usage with TanStack Query

// hooks/​use{Feature}.ts
import { useQuery } from "@tanstack/​react-query";
import { mock{Feature}Data, {Feature}Data } from "../​data/​mock-{feature}";

async function fetch{Feature}Data(): Promise<{Feature}Data> {
    await new Promise((r) => setTimeout(r, 500)); // Simulate API
    return mock{Feature}Data;
}

export function use{Feature}() {
    return useQuery({
        queryKey: ["{feature}"],
        queryFn: fetch{Feature}Data,
    });
}
