feat!: migrate scrapegraph-js to api v2

[lurenss]

Summary

Full rewrite of scrapegraph-js from v1 flat-function API to v2 client factory targeting /api/v2/* endpoints.

What changed

• Client factory: scrapegraphai({ apiKey, baseUrl?, timeout?, maxRetries? }) replaces all standalone functions
• Endpoints: scrape, extract, search, credits, history as top-level methods; crawl.* and monitor.* as namespaced sub-objects
• Request layer (src/http.ts): retry on 502/503 with exponential backoff, Authorization + SGAI-APIKEY + X-SDK-Version headers, configurable timeout and AbortSignal support
• Schemas (src/schemas.ts): Zod v4 validation schemas copied from sgai-stack shared contracts — used for type derivation, not runtime validation in the SDK
• Zod-to-JSON-schema (src/zod.ts): converts Zod v3/v4 schemas to JSON Schema so consumers can pass z.object(...) to extract({ schema })
• URL validation (src/url.ts): private/internal hostname and IP blocking (used server-side, exported for contract alignment)
• Fetch mode enum: replaced render/stealth booleans with fetchConfig.mode enum (auto, fast, js, direct+stealth, js+stealth)
• Extract endpoint: removed fetchConfig and llmConfig from extract body — extract only accepts url, prompt, schema, mode, contentType
• Nationality param: added nationality (2-letter ISO) to search endpoint
• Types: all derived from Zod schemas via z.infer<>, exported from src/types/index.ts
• Migration guide: MIGRATION.md with v1→v2 mapping for every function, parameter, and type

Removed

• src/scrapegraphai.ts (old monolithic module with smartScraper, searchScraper, markdownify, agenticScraper, sitemap, generateSchema, checkHealth)
• src/env.ts (env-based config)
• tsup.config.ts (replaced with bun build)
• integration_test.ts (replaced with unit test suite)
• All examples/ (to be recreated for v2 API)
• .DS_Store

Breaking changes

• All v1 exports removed — consumers must use scrapegraphai() factory
• crawl and monitor are namespaced (crawl.start, monitor.create, etc.)
• All requests target /api/v2/*
• Return type is { data, requestId }, errors throw
• snake_case params replaced with camelCase
• Node.js >= 22 required

Test plan

• 16 unit tests pass (bun test) — mock HTTP servers, no real API calls
• tests/http.test.ts: POST body, retry on 502, auth headers, 401 error
• tests/client.test.ts: scrape, extract, search, search+nationality, credits, crawl.start/status/stop, monitor.create/delete, fetchConfig.mode, history query params
• tests/zod.test.ts: Zod object/optional/array/nested conversion, raw passthrough
• Type-check passes (tsc --noEmit)
• Integration tested against localhost:3002 — all endpoints working

Client surface

const sgai = scrapegraphai({ apiKey: "sgai-..." });

// Top-level
sgai.scrape(url, options?)         // POST /api/v2/scrape
sgai.extract(url, extractOptions)  // POST /api/v2/extract
sgai.search(query, options?)       // POST /api/v2/search
sgai.credits()                     // GET  /api/v2/credits
sgai.history(filter?)              // GET  /api/v2/history

// Crawl namespace
sgai.crawl.start(url, options?)    // POST /api/v2/crawl
sgai.crawl.status(id)              // GET  /api/v2/crawl/:id
sgai.crawl.stop(id)                // POST /api/v2/crawl/:id/stop
sgai.crawl.resume(id)              // POST /api/v2/crawl/:id/resume

// Monitor namespace
sgai.monitor.create(input)         // POST   /api/v2/monitor
sgai.monitor.list()                // GET    /api/v2/monitor
sgai.monitor.get(id)               // GET    /api/v2/monitor/:id
sgai.monitor.pause(id)             // POST   /api/v2/monitor/:id/pause
sgai.monitor.resume(id)            // POST   /api/v2/monitor/:id/resume
sgai.monitor.delete(id)            // DELETE /api/v2/monitor/:id

Fetch mode enum (fetchConfig.mode)

Replaced the old render/stealth booleans:

Value	Description
auto	Tries all providers in order (default)
fast	Direct HTTP only (impit)
js	JavaScript rendering
direct+stealth	Residential proxy
js+stealth	JS render + stealth proxy

Extract endpoint (simplified)

Extract accepts only: url, prompt, schema, mode, contentType.
fetchConfig and llmConfig have been removed from this endpoint.

Search endpoint — nationality

Added nationality parameter (2-letter ISO code, maps to hl in Serper for language-targeted results).

Request layer

• Headers: Authorization: Bearer <key>, SGAI-APIKEY: <key>, X-SDK-Version: js@2.0.0
• Retry on 502/503 with exponential backoff (default 2 retries)
• Retry on network errors (TypeError — fetch failed, connection refused)
• Configurable timeout (default 30s) and AbortSignal support
• Timeout range: 1000–60000ms

Unit tests — 16/16 ✅

File	Tests	Coverage
tests/http.test.ts	4	POST body, retry on 502, auth headers, 401 error
tests/client.test.ts	7	scrape, extract, search, search+nationality, credits, crawl (start/status/stop), monitor (create/delete), fetchConfig.mode, history query params
tests/zod.test.ts	5	Zod object, raw passthrough, optional fields, arrays, nested objects

Integration tests (localhost:3002) ✅

Endpoint	Tests	Status
scrape (markdown, html, screenshot, mock, stealth, all 5 fetch modes)	12	✅
extract (basic, schema, complex, fetchConfig, llmConfig)	5	✅
search (basic, numResults, llmConfig, nationality)	4	✅
history (no filters, limit, service filter)	4	✅
credits	1	✅
Error handling (invalid API key)	1	✅

Pending changes (uncommitted)

Two uncommitted changes ready to be committed:

1. src/schemas.ts: added nationality field to apiSearchRequestSchema
2. tests/client.test.ts: added search forwards nationality test
