🔑 Key Concepts

GraphQL

  • Queries: Fetch data from Neo4j
  • Mutations: Create, update, delete data
  • Variables: Type-safe query parameters
  • Fragments: Reusable field selections
  • Filtering: WHERE clauses with operators

React Query

  • useQuery: Fetch and cache data
  • useMutation: Modify data
  • Query Keys: Cache identification
  • Invalidation: Refresh stale data
  • Optimistic Updates: UI updates before server confirms

Neo4j DataAPI GraphQL

  • Nodes: Movies, People entities
  • Relationships: ACTED_IN, DIRECTED
  • Connect/Disconnect: Relationship management
  • Traversal: Following relationships in queries
  • Filtering: Complex WHERE conditions

Component Architecture

  • Container Components: Data fetching
  • Presentation Components: UI rendering
  • Custom Hooks: Reusable logic
  • Type Safety: TypeScript interfaces

🛠️ Tech Stack Details

Technology Version Purpose
React 18+ UI framework
TypeScript 5+ Type safety
Vite 5+ Build tool
graphql-request 6+ GraphQL client
TanStack Query 5+ Data fetching & caching
Tailwind CSS 3+ Styling
Neo4j Aura - Graph database
DataAPI GraphQL - GraphQL API layer

📖 Common Workflows

Creating a New Feature

  1. Define GraphQL Operations

    // src/graphql/myFeature.ts
export const MY_QUERY = gql`...`;
export const MY_MUTATION = gql`...`;

  2. Create TypeScript Types

    // src/types/myFeature.ts
export interface MyData { ... }

  3. Build Custom Hook (optional)

    // src/hooks/useMyFeature.ts
export function useMyFeature() { ... }

  4. Create Components

    // src/components/MyFeature.tsx
export function MyFeature() { ... }

  5. Add to App

    // src/App.tsx
import { MyFeature } from './components/MyFeature';

Debugging a Problem

  1. Check TROUBLESHOOTING.md for common issues
  2. Open React Query DevTools to inspect queries
  3. Check browser Network tab for GraphQL requests
  4. Verify environment variables are set correctly
  5. Test queries in GraphQL Playground
  6. Ask for help in Neo4j Community

Optimizing Performance

  1. Review BEST_PRACTICES.md performance section
  2. Implement pagination for large datasets
  3. Use React Query's staleTime appropriately
  4. Add prefetching for predictable navigation
  5. Monitor bundle size and code-split if needed
  6. Use React Query DevTools to identify slow queries

npm create vite@latest my-app -- --template react-ts

# Install dependencies
npm install graphql-request graphql @tanstack/react-query

# Development
npm run dev

# Build for production
npm run build

# Preview production build
npm run preview

Essential Imports

// GraphQL Client
import { GraphQLClient } from 'graphql-request';
import { gql } from 'graphql-request';

// React Query
import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';

// React
import { useState, useEffect } from 'react';

Common Patterns

// Query
const { data, isLoading, error } = useQuery({
  queryKey: ['key'],
  queryFn: () => graphqlClient.request(QUERY)
});

// Mutation
const mutation = useMutation({
  mutationFn: (data) => graphqlClient.request(MUTATION, data),
  onSuccess: () => queryClient.invalidateQueries({ queryKey: ['key'] })
});

// Conditional Query
const { data } = useQuery({
  queryKey: ['key', id],
  queryFn: () => graphqlClient.request(QUERY, { id }),
  enabled: !!id
});

// Relationship Connect
updateMovies(
  where: { title: "Movie" }
  connect: { actors: { where: { node: { name: "Actor" }}}}
)

// Relationship Disconnect
updateMovies(
  where: { title: "Movie" }
  disconnect: { actors: { where: { node: { name: "Actor" }}}}
)
