JavaScript execution
Playwright for dynamic sizing

Sizing grids and stock availability on Joules load dynamically via API calls. We use Playwright to render the page fully, ensuring accurate stock capture per variant.

Variant expansion
Mapping parent to child SKUs

Apparel scraping requires unwrapping parent products into individual colour and size combinations. Our parsers normalise this into a flat, queryable structure.

UK Residential Proxies
Localised pricing and routing

We route requests through UK-based residential proxies to ensure we capture accurate GBP pricing and avoid geo-blocks or currency redirects.

Change detection
Only re-scrape what's changed

We maintain a hash index of last-seen values per field. Subsequent runs only push diffs — reducing compute cost and downstream processing load.

Observability
24/7 pipeline health

Every run emits structured logs to our observability stack. We alert on null-rate spikes or schema drift and respond immediately.

Why DataFlirt

"Joules presents a highly structured apparel catalogue, but tracking daily size-level availability and promotional pricing requires dedicated infrastructure."

Common questions.

About joules.com scraping, legality, and pipeline operations.

Ask us directly →
Can you extract inventory data at the size level?

Yes. We render the product page using Playwright to interact with the size selector, capturing in-stock, out-of-stock, and low-stock indicators for every individual size variant.

How often can the pipeline run?

For Joules, we typically recommend daily runs to capture pricing changes and stock depletion accurately. Hourly runs can be configured for specific high-priority categories.

Do you capture promotional pricing?

Yes. We extract the current selling price, original RRP, discount percentages, and any promotional banner text (e.g., '20% off at checkout') applied to the item.

Can I get a feed of only new products?

Yes. Our change detection system can be configured to emit only newly discovered SKUs, or specifically flag items that have dropped out of stock since the last run.

Are product reviews included?

Yes. We can paginate through the review sections to extract star ratings, review text, and helpfulness metrics for sentiment analysis.

What format is the data delivered in?

We deliver in JSON, CSV, or Parquet. We push directly to your S3 bucket, BigQuery, Snowflake, or via Webhook for integration into your existing systems.
