# Next.js Integration Guide
|
|
|
|
Complete guide to integrating Brainy with Next.js applications, covering App Router, Pages Router, API routes, and deployment strategies.
|
|
|
|
## 🚀 Quick Start
|
|
|
|
### Installation
|
|
|
|
```bash
|
|
npx create-next-app@latest my-brainy-app
|
|
cd my-brainy-app
|
|
npm install @soulcraft/brainy
|
|
```
|
|
|
|
### Basic Setup
|
|
|
|
```jsx
|
|
// app/components/BrainyProvider.jsx
|
|
'use client'
|
|
import { createContext, useContext, useEffect, useState } from 'react'
|
|
import { Brainy } from '@soulcraft/brainy'
|
|
|
|
const BrainyContext = createContext()
|
|
|
|
export function BrainyProvider({ children }) {
|
|
const [brain, setBrain] = useState(null)
|
|
const [isReady, setIsReady] = useState(false)
|
|
|
|
useEffect(() => {
|
|
const initBrain = async () => {
|
|
const newBrain = new Brainy({
|
|
storage: { type: 'opfs' } // Browser storage for client-side
|
|
})
|
|
await newBrain.init()
|
|
setBrain(newBrain)
|
|
setIsReady(true)
|
|
}
|
|
|
|
initBrain()
|
|
}, [])
|
|
|
|
return (
|
|
<BrainyContext.Provider value={{ brain, isReady }}>
|
|
{children}
|
|
</BrainyContext.Provider>
|
|
)
|
|
}
|
|
|
|
export const useBrainy = () => {
|
|
const context = useContext(BrainyContext)
|
|
if (!context) {
|
|
throw new Error('useBrainy must be used within BrainyProvider')
|
|
}
|
|
return context
|
|
}
|
|
```
|
|
|
|
## 📱 App Router (Next.js 13+)
|
|
|
|
### Root Layout Setup
|
|
|
|
```jsx
|
|
// app/layout.jsx
|
|
import { BrainyProvider } from './components/BrainyProvider'
|
|
import './globals.css'
|
|
|
|
export const metadata = {
|
|
title: 'My Brainy App',
|
|
description: 'AI-powered search with Brainy'
|
|
}
|
|
|
|
export default function RootLayout({ children }) {
|
|
return (
|
|
<html lang="en">
|
|
<body>
|
|
<BrainyProvider>
|
|
{children}
|
|
</BrainyProvider>
|
|
</body>
|
|
</html>
|
|
)
|
|
}
|
|
```
|
|
|
|

## ⚡ Performance Optimization
|
|
|
|
### Client-Side Optimization
|
|
|
|
```jsx
|
|
// app/hooks/useBrainCache.js
|
|
import { useState, useCallback, useMemo } from 'react'
|
|
|
|
export function useBrainCache() {
|
|
const [cache, setCache] = useState(new Map())
|
|
|
|
const getCachedResult = useCallback((query) => {
|
|
return cache.get(query)
|
|
}, [cache])
|
|
|
|
const setCachedResult = useCallback((query, result) => {
|
|
setCache(prev => {
|
|
const newCache = new Map(prev)
|
|
newCache.set(query, result)
|
|
// Keep only last 100 results
|
|
if (newCache.size > 100) {
|
|
const firstKey = newCache.keys().next().value
|
|
newCache.delete(firstKey)
|
|
}
|
|
return newCache
|
|
})
|
|
}, [])
|
|
|
|
return { getCachedResult, setCachedResult }
|
|
}
|
|
```
|
|
|
|
### Debounced Search
|
|
|
|
```jsx
|
|
// app/hooks/useDebounceSearch.js
|
|
import { useState, useEffect, useCallback } from 'react'
|
|
import { useBrainy } from '../components/BrainyProvider'
|
|
|
|
export function useDebounceSearch(delay = 300) {
|
|
const { brain, isReady } = useBrainy()
|
|
const [query, setQuery] = useState('')
|
|
const [results, setResults] = useState([])
|
|
const [loading, setLoading] = useState(false)
|
|
|
|
const search = useCallback(async (searchQuery) => {
|
|
if (!isReady || !searchQuery.trim()) {
|
|
setResults([])
|
|
return
|
|
}
|
|
|
|
setLoading(true)
|
|
try {
|
|
const searchResults = await brain.find(searchQuery)
|
|
setResults(searchResults)
|
|
} catch (error) {
|
|
console.error('Search error:', error)
|
|
setResults([])
|
|
} finally {
|
|
setLoading(false)
|
|
}
|
|
}, [brain, isReady])
|
|
|
|
useEffect(() => {
|
|
const timer = setTimeout(() => {
|
|
search(query)
|
|
}, delay)
|
|
|
|
return () => clearTimeout(timer)
|
|
}, [query, delay, search])
|
|
|
|
return { query, setQuery, results, loading }
|
|
}
|
|
```

|
## 🔒 Security Best Practices
|
|
|
|
### Input Validation
|
|
|
|
```javascript
|
|
// app/utils/validation.js
|
|
export function validateSearchQuery(query) {
|
|
if (typeof query !== 'string') {
|
|
throw new Error('Query must be a string')
|
|
}
|
|
|
|
if (query.length > 1000) {
|
|
throw new Error('Query too long')
|
|
}
|
|
|
|
// Sanitize query
|
|
return query.trim()
|
|
}
|
|
|
|
export function validateDataInput(data, type, metadata) {
|
|
if (!data || !type) {
|
|
throw new Error('Data and type are required')
|
|
}
|
|
|
|
if (typeof data !== 'string') {
|
|
throw new Error('Data must be a string')
|
|
}
|
|
|
|
if (data.length > 10000) {
|
|
throw new Error('Data too long')
|
|
}
|
|
|
|
return { data: data.trim(), type, metadata }
|
|
}
|
|
```
|
|
|
|
### Rate Limiting
|
|
|
|
```javascript
|
|
// app/middleware/rateLimit.js
|
|
const requests = new Map()
|
|
|
|
export function rateLimit(req, limit = 100, window = 60000) {
|
|
const ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress
|
|
const now = Date.now()
|
|
|
|
if (!requests.has(ip)) {
|
|
requests.set(ip, [])
|
|
}
|
|
|
|
const userRequests = requests.get(ip)
|
|
|
|
// Remove old requests
|
|
const validRequests = userRequests.filter(time => now - time < window)
|
|
|
|
if (validRequests.length >= limit) {
|
|
throw new Error('Rate limit exceeded')
|
|
}
|
|
|
|
validRequests.push(now)
|
|
requests.set(ip, validRequests)
|
|
|
|
return true
|
|
}
|
|
```

## 📚 Advanced Patterns
|
|
|
|
### Context + Reducer Pattern
|
|
|
|
```jsx
|
|
// app/contexts/BrainyContext.jsx
|
|
'use client'
|
|
import { createContext, useContext, useReducer, useEffect } from 'react'
|
|
import { Brainy } from '@soulcraft/brainy'
|
|
|
|
const BrainyContext = createContext()
|
|
|
|
const initialState = {
|
|
brain: null,
|
|
isReady: false,
|
|
error: null,
|
|
stats: null
|
|
}
|
|
|
|
function brainyReducer(state, action) {
|
|
switch (action.type) {
|
|
case 'INIT_START':
|
|
return { ...state, error: null }
|
|
case 'INIT_SUCCESS':
|
|
return { ...state, brain: action.brain, isReady: true, error: null }
|
|
case 'INIT_ERROR':
|
|
return { ...state, error: action.error, isReady: false }
|
|
case 'UPDATE_STATS':
|
|
return { ...state, stats: action.stats }
|
|
default:
|
|
return state
|
|
}
|
|
}
|
|
|
|
export function BrainyProvider({ children }) {
|
|
const [state, dispatch] = useReducer(brainyReducer, initialState)
|
|
|
|
useEffect(() => {
|
|
const initBrain = async () => {
|
|
dispatch({ type: 'INIT_START' })
|
|
try {
|
|
const brain = new Brainy()
|
|
await brain.init()
|
|
dispatch({ type: 'INIT_SUCCESS', brain })
|
|
|
|
// Load initial stats
|
|
const stats = await brain.stats()
|
|
dispatch({ type: 'UPDATE_STATS', stats })
|
|
} catch (error) {
|
|
console.error('Brain initialization failed:', error)
|
|
dispatch({ type: 'INIT_ERROR', error: error.message })
|
|
}
|
|
}
|
|
|
|
initBrain()
|
|
}, [])
|
|
|
|
return (
|
|
<BrainyContext.Provider value={{ state, dispatch }}>
|
|
{children}
|
|
</BrainyContext.Provider>
|
|
)
|
|
}
|
|
|
|
export const useBrainyContext = () => {
|
|
const context = useContext(BrainyContext)
|
|
if (!context) {
|
|
throw new Error('useBrainyContext must be used within BrainyProvider')
|
|
}
|
|
return context
|
|
}
|
|
```
|
|
|
|
## 🔍 Testing

|
|
|
```javascript

|
import { render, screen, waitFor } from '@testing-library/react'
|
|
import { BrainyProvider } from '../app/components/BrainyProvider'
|
|
import { Search } from '../app/components/Search'
|
|
|
|
// Mock Brainy
|
|
jest.mock('@soulcraft/brainy', () => ({
|
|
Brainy: jest.fn().mockImplementation(() => ({
|
|
init: jest.fn().mockResolvedValue(undefined),
|
|
find: jest.fn().mockResolvedValue([
|
|
{ id: '1', data: 'Test result', score: 0.9 }
|
|
])
|
|
}))
|
|
}))
|
|
|
|
describe('Search Component', () => {
|
|
it('renders search input', async () => {
|
|
render(
|
|
<BrainyProvider>
|
|
<Search />
|
|
</BrainyProvider>
|
|
)
|
|
|
|
await waitFor(() => {
|
|
expect(screen.getByPlaceholderText('Search with AI...')).toBeInTheDocument()
|
|
})
|
|
})
|
|
})
|
|
```
