1688 Logistics Scraper

Extract product weight, size, and logistics data from 1688 product pages.

Run

bun scripts/run.ts scrape <url> [--dry-run]

Examples

bun scripts/run.ts scrape 'https://detail.1688.com/offer/852504650877.html'
bun scripts/run.ts scrape 'https://detail.1688.com/offer/852504650877.html' --dry-run

What It Does

Opens the 1688 product URL in the browser (port 18800)
Extracts weight/size data from wherever it appears on the page — product attributes, variant specs, 包装信息, 商品件重尺 table, logistics section
Downloads detail images (商品详情图片) for analysis — weight/size is often only in images
Outputs structured JSON

Where To Look For Data

Weight/size data on 1688 pages hides in multiple places. Check all before giving up:

Product attributes (商品属性 / 商品参数) — key-value table, most reliable
商品件重尺 table — dedicated weight/dimensions/volume table for logistics
包装信息 section — packaging type, box weight, box dimensions, units per box
Variant/SKU specs — per-variant weight or size
Logistics section — shipping weight, volume, freight info
Detail images — downloaded to /tmp/1688-logistics/<offer-id>/, read them to find weight/size text baked into images

null = not found in text. Check detailImages — the data may be in the images.

Rules

If the browser is not running, report the error. Do not try to launch it.
Check all data sources before reporting null.
Normalize units: 克→kg, 毫米→cm. Keep raw values in rawAttributes and raw fields.
No retries. If it fails, report as-is.
Trust page content. Do not guess values.
