Bright Data JavaScript SDK

Access web data through a unified Node.js/TypeScript SDK (@brightdata/sdk). One client, several services: web unlocking (scrapeUrl), platform scraping (scrape.<platform>), SERP search (search.google/bing/yandex), AI discovery (discover), datasets, browser automation, and Scraper Studio.

Requires Node.js ≥ 20. Ships ESM + CommonJS with full TypeScript types. The client is exported as bdclient (lowercase — not a typo).

Setup gate (do first)

npm install @brightdata/sdk     # or: pnpm add / yarn add

The client reads the BRIGHTDATA_API_TOKEN env var, or you pass { apiKey }. Get a token at https://brightdata.com/cp/setting/users.

// ESM (package.json "type": "module", or .mjs)
import { bdclient } from '@brightdata/sdk';

// CommonJS (.cjs / "type": "commonjs")
const { bdclient } = require('@brightdata/sdk');

const client = new bdclient();             // reads BRIGHTDATA_API_TOKEN
// const client = new bdclient({ apiKey: '...' });
try {
  const html = await client.scrapeUrl('https://example.com');
} finally {
  await client.close();                    // always close (or `await using`)
}

await using client = new bdclient() (TS 5.2+ / Node ≥20) auto-closes at scope end.

Service Selection (decide first, then look up the method)

Pick the service BEFORE reaching for a specific method. Most routing mistakes come from skipping this step and pattern-matching on keywords.

Have a URL?
  ├── On a supported platform (Amazon, LinkedIn, Facebook, Instagram, YouTube,
  │   TikTok, Reddit, Pinterest, ChatGPT, Perplexity, DigiKey)?
  │     → Platform scraping: client.scrape.<platform>.<method>(urls, opts?)
  │
  ├── Generic page (no dedicated platform scraper)?
  │     → Web unlocker: client.scrapeUrl(url, { dataFormat: 'markdown' })
  │
  └── Need login / JS / click-scroll-fill / CAPTCHA / multi-step nav?
        → Browser API: client.browser.getConnectUrl() (connect via Playwright)

No URL?
  ├── Want entities matching natural-language criteria
  │   ("find AI startups in Berlin", "competitors of Acme")?
  │     → Discover: client.discover(query, { intent })
  │
  ├── Want web pages / search-result links ("search Google for X")?
  │     → SERP: client.search.google(query) [or .bing / .yandex]
  │
  ├── Want to search WITHIN a platform ("Amazon products by keyword",
  │   "LinkedIn jobs", "Instagram reels by profile")?
  │     → Platform discovery: client.scrape.<platform>.discover*(filters)
  │       or amazon.productSearch(...)  (NOTE: client.search is SERP-only here)
  │
  └── Want bulk/historical data at scale?
        → Datasets: client.datasets.<name>.query(filter) → .download(snapshotId)

Edge cases:

• Supported-platform URL BUT user mentions login/click/scroll/JS → Browser API (the interaction trumps the platform).
• Supported-platform scrape returns 403/blocked → fall back to client.scrapeUrl() (web unlocker).
• "Find/research who are X" with a URL alongside ("competitors of acme.com") → still Discover; the URL is context, not the scrape target.

⚠️ Key differences from the Python SDK

If you know the Python SDK (brightdata-sdk), the JS surface differs — do not port names blindly:

Method Names: Verify Before Asserting

Before claiming a platform method exists/doesn't exist, consult references/scrapers.md — it lists every platform's verified methods. The SDK ships TypeScript types, so in a typed project you can also let the compiler/editor confirm a method exists.

Each platform exposes up to three method styles (see references/scrapers.md):

• collect<Thing>(input, opts?) — returns the rows directly (object[]).
• <thing>(input, opts?) — orchestrated (trigger → poll → download); returns { data, status, rowCount }. Default to this.
• discover<Thing>By<X>(filters, opts?) — find items by keyword/category/URL filter instead of by direct URL.

Likely hallucinations (do NOT write these — verify in references/scrapers.md):

Useful standalone methods

Gotchas

• Always await client.close() (or await using). The client holds a keep-alive transport; leaking it hangs the process.
• client.search is SERP-only (google/bing/yandex). To search within a platform, use that platform's discover* / productSearch scraper methods — there is no client.search.amazon.
• chatGPT is camelCase on client.scrape — client.scrape.chatGPT.search(...), not .chatgpt.
• Batch: pass an array, don't loop. scrapeUrl([...urls]) and search.google([...queries]) run in parallel internally. For platform scrapers with many inputs, prefer the orchestrated method with an array, or the *Trigger + job.wait() pattern (see references/advanced.md). Don't wrap blocking calls in Promise.all of single-item calls — you'll fight the rate limiter.
• Orchestrated methods block for minutes. products/profiles/etc. trigger a job and poll until ready (often 2–10 min). Don't set tiny pollTimeouts; tune via { pollInterval, pollTimeout }. Defaults are calibrated.
• Datasets are historical/bulk, not live. Need current data → use platform scrapers or scrapeUrl. query() returns a snapshotId; download() blocks until the snapshot is ready.
• Web unlocker fallback on 403. If a platform scraper is blocked, retry the URL through client.scrapeUrl().
• Don't add your own retry loop. The transport already retries network/timeout errors with backoff; double-retrying wastes credits. Tune timeout / rateLimit on the constructor instead.
• Cost hierarchy (cheapest first): datasets → SERP → platform scrapers → web unlocker → discover → Scraper Studio → Browser API. Prefer the cheapest service that satisfies the request.

Error handling

All errors extend BRDError. Import the specific classes to branch:

import { bdclient, ValidationError, AuthenticationError, BRDError } from '@brightdata/sdk';

try {
  const data = await client.scrape.amazon.products(['https://www.amazon.com/dp/B0D77BX8Y4']);
} catch (err) {
  if (err instanceof AuthenticationError) { /* bad/expired token */ }
  else if (err instanceof ValidationError) { /* bad input */ }
  else if (err instanceof BRDError) { /* any SDK error */ }
  else throw err;
}

Classes: BRDError (base), ValidationError, AuthenticationError, ZoneError, NetworkError, NetworkTimeoutError, TimeoutError, APIError, DataNotReadyError, FSError.

Examples

Scrape a generic page as markdown

const md = await client.scrapeUrl('https://example.com/article', { dataFormat: 'markdown' });

Get an Amazon product (orchestrated — default)

const res = await client.scrape.amazon.products(['https://www.amazon.com/dp/B0D77BX8Y4']);
console.log(res.status, res.rowCount, res.data);

SERP, batched

const results = await client.search.google(['best running shoes', 'best trail shoes'], { country: 'us' });

Find entities (Discover)

const startups = await client.discover('AI startups in Berlin', {
  intent: 'early-stage machine-learning companies',
  numResults: 10,
});

Bulk/historical via datasets

const ds = client.datasets;
const snapshotId = await ds.instagramProfiles.query({ url: 'https://www.instagram.com/natgeo/' }, { records_limit: 50 });
// download() blocks until the snapshot is ready
const rows = await ds.instagramProfiles.download(snapshotId);

Troubleshooting

• AuthenticationError / 401 — token missing or invalid. Check BRIGHTDATA_API_TOKEN or the apiKey option.
• 403 / blocked — site blocked the scraper. Retry the URL via client.scrapeUrl() (web unlocker).
• Timeout — increase timeout (constructor, 1000–300000 ms) or the orchestrated pollTimeout; do not lower it.
• "Dataset not found" — call client.datasets.list(); dataset names are camelCase (amazonProducts, linkedinProfiles).
• Process hangs after work finishes — you forgot await client.close().
• SSL/proxy errors in sandboxes — see references/advanced.md for zone/SSL options.
• Rate-limit errors — set { rateLimit, ratePeriod } on the constructor, or batch via arrays / the trigger pattern instead of Promise.all.

When to load references

• references/scrapers.md — when the user names Amazon, LinkedIn, Facebook, Instagram, YouTube, TikTok, Reddit, Pinterest, ChatGPT, Perplexity, DigiKey — verified per-platform method tables (collect / orchestrated / discover) and the scrapeUrl web-unlocker options.
• references/search.md — SERP engines (search.google/bing/yandex) and the Discover API (discover / discoverTrigger), with all options.
• references/datasets-overview.md — dataset names, the query → getStatus → download lifecycle, and filters.
• references/advanced.md — constructor options & env vars, batch/trigger orchestration, Browser API (Playwright/Puppeteer), Scraper Studio, error classes, and zones/SSL.
