Token Limit Exceeded + +**Problem**: Even individual sections exceed token limits +**Solution**: Reduce `maxTokensPerSection` or simplify prompts + +```typescript +const generator = new MultiStepReadmeGenerator(apiKey, githubToken, { + maxTokensPerSection: 600, // Reduce from default 800 +}); +``` + +#### 2. Rate Limiting + +**Problem**: API rate limits exceeded +**Solution**: Reduce concurrency and add delays + +```typescript +const generator = new MultiStepReadmeGenerator(apiKey, githubToken, { + concurrentSections: 1, // Generate one section at a time +}); +``` + +#### 3. GitHub API Rate Limits + +**Problem**: Repository analysis fails due to rate limits +**Solution**: Provide GitHub token and implement caching + +```typescript +// Implement simple caching +const cache = new Map(); + +class CachedRepositoryAnalyzer extends RepositoryAnalyzer { + async analyzeRepository(owner: string, repo: string) { + const key = `${owner}/${repo}`; + + if (cache.has(key)) { + return cache.get(key); + } + + const result = await super.analyzeRepository(owner, repo); + cache.set(key, result); + + return result; + } +} +``` + +#### 4. Incomplete Sections + +**Problem**: Some sections are consistently incomplete +**Solution**: Increase retries or customize prompts + +```typescript +// Custom prompt for problematic section +const customPrompts = { + installation: `Generate concise installation instructions for "${metadata.name}". + + Context: ${structure.techStack.primary} project + + Requirements: + - Prerequisites (if any) + - Single command installation + - Verification step + + Keep it under 300 words. Return only markdown.`, +}; +``` + +### Debug Mode + +Enable detailed logging: + +```typescript +// Set environment variable +process.env.DEBUG_README_GENERATION = 'true'; + +// In the generator +if (process.env.DEBUG_README_GENERATION === 'true') { + console.log('Section generation details:', { + sectionId, + prompt: prompt.substring(0, 200) + '...', + result: result.success ? 'success' : 'failed', + tokensUsed: result.tokensUsed, + }); +} +``` + +## πŸ“ˆ Performance Optimizations + +### 1. Caching Strategy + +Implement Redis caching for repository analysis: + +```typescript +import Redis from 'ioredis'; + +const redis = new Redis(process.env.REDIS_URL); + +class CachedAnalyzer extends RepositoryAnalyzer { + async analyzeRepository(owner: string, repo: string) { + const key = `repo:${owner}:${repo}`; + const cached = await redis.get(key); + + if (cached) { + return JSON.parse(cached); + } + + const result = await super.analyzeRepository(owner, repo); + await redis.setex(key, 3600, JSON.stringify(result)); // 1 hour cache + + return result; + } +} +``` + +### 2. Background Processing + +For large repositories, use background jobs: + +```typescript +import Bull from 'bull'; + +const readmeQueue = new Bull('readme generation'); + +// API route for immediate response +export async function POST(request: Request) { + const { githubUrl } = await request.json(); + + const job = await readmeQueue.add('generate', { githubUrl }); + + return Response.json({ + jobId: job.id, + status: 'queued', + }); +} + +// Background worker +readmeQueue.process('generate', async (job) => { + const { githubUrl } = job.data; + const generator = new MultiStepReadmeGenerator(...); + + return generator.generateReadme(githubUrl); +}); +``` + +### 3. Streaming Responses + +Stream sections as they're generated: + +```typescript +export async function POST(request: Request) { + const { githubUrl } = await request.json(); + + const stream = new ReadableStream({ + async start(controller) { + const generator = new MultiStepReadmeGenerator(...); + + // Override assembler to stream results + const originalAssembler = generator.assembler; + generator.assembler.generateSectionsInBatches = async (...args) => { + // Stream each section as it's completed + // Implementation details... + }; + + const result = await generator.generateReadme(githubUrl); + controller.close(); + }, + }); + + return new Response(stream, { + headers: { + 'Content-Type': 'text/event-stream', + 'Cache-Control': 'no-cache', + 'Connection': 'keep-alive', + }, + }); +} +``` + +## πŸ§ͺ Testing + +### Unit Tests + +```typescript +// __tests__/readme-generator.test.ts +import { MultiStepReadmeGenerator, RepositoryAnalyzer } from '@/lib/multi-step-readme-generator'; + +describe('MultiStepReadmeGenerator', () => { + it('should generate complete README for public repository', async () => { + const generator = new MultiStepReadmeGenerator( + process.env.GEMINI_API_KEY, + process.env.GITHUB_TOKEN + ); + + const result = await generator.generateReadme( + 'https://github.com/octocat/Hello-World' + ); + + expect(result.success).toBe(true); + expect(result.readme).toContain('# Hello-World'); + expect(result.stats.sectionsGenerated).toBeGreaterThan(0); + }); +}); +``` + +### Integration Tests + +```typescript +describe('API Integration', () => { + it('should handle README generation request', async () => { + const response = await fetch('/api/generate', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ + githubUrl: 'https://github.com/octocat/Hello-World' + }), + }); + + const result = await response.json(); + + expect(response.status).toBe(200); + expect(result.success).toBe(true); + expect(result.readme).toBeDefined(); + }); +}); +``` + +## πŸ“š API Reference + +### Main Classes + +- **`MultiStepReadmeGenerator`**: Main orchestrator class +- **`RepositoryAnalyzer`**: Analyzes GitHub repositories +- **`SectionPlanner`**: Plans optimal README sections +- **`SectionGenerator`**: Generates individual sections +- **`ReadmeAssembler`**: Assembles and validates final README + +### Configuration Options + +```typescript +interface GenerationConfig { + maxRetries: number; // Default: 3 + maxTokensPerSection: number; // Default: 800 + temperature: number; // Default: 0.7 + concurrentSections: number; // Default: 3 + enableContinuation: boolean; // Default: true +} +``` + +### Section Types + +- **Critical**: `header`, `description`, `installation` +- **High**: `features`, `usage`, `api` +- **Medium**: `configuration`, `development`, `contributing`, `deployment` +- **Low**: `testing`, `examples` + +This comprehensive integration guide provides everything needed to successfully implement the multi-step README generation pipeline in the ReadmeGenAI project, solving the token limit issues while providing a more robust and reliable generation process. \ No newline at end of file diff --git a/src/app/api/generate/route.ts b/src/app/api/generate/route.ts index acb17e5..25fd97e 100644 --- a/src/app/api/generate/route.ts +++ b/src/app/api/generate/route.ts @@ -1,170 +1,138 @@ -import { NextResponse } from "next/server"; -import { getGeminiModel } from "@/lib/gemini"; -import { getRepoData, getRepoContents } from "@/lib/octokit"; -import { SUPPORTED_LANGUAGES } from "@/constants/languages"; +import { NextRequest, NextResponse } from 'next/server'; +import { MultiStepReadmeGenerator } from '@/lib/multi-step-readme-generator'; -export const dynamic = "force-dynamic"; +export const dynamic = 'force-dynamic'; /** - * AI README Generation Endpoint - * Optimized for data accuracy, clean prompt interpolation, and multi-language support. - * - * @param {Request} req - The incoming Next.js/standard Web API Request object containing the repo URL and optional language. - * @returns {Promise} A JSON response containing the generated Markdown or an error message. + * Enhanced Multi-Step README Generation Endpoint + * + * This endpoint uses a sophisticated multi-step approach to generate READMEs: + * 1.
