Douban Sync

Export Douban collections (books, movies, music, games) to CSV and keep them in sync via RSS.

Two Modes

1. Full Export (first time)

Use the browser tool to scrape all collection pages. Requires the user to be logged into Douban.

browser → douban.com/people/{USER_ID}/{category}?start=0&sort=time&mode=list

Categories and URL paths:

Books: book.douban.com/people/{ID}/collect (读过), /do (在读), /wish (想读)
Movies: movie.douban.com/people/{ID}/collect (看过), /do (在看), /wish (想看)
Music: music.douban.com/people/{ID}/collect (听过), /do (在听), /wish (想听)
Games: www.douban.com/people/{ID}/games?action=collect (玩过), =do (在玩), =wish (想玩)

Each page shows up to 30 items in list mode (some pages may have fewer due to delisted entries). Paginate with ?start=0,30,60... — the script uses the paginator's "next" button to determine whether to continue.

Rate limiting: Wait 2-3 seconds between pages. If blocked, wait 30 seconds and retry.

Scripts:

scripts/douban-scraper.mjs — HTTP-only, no browser needed (may get rate-limited)
scripts/douban-browser-scraper.mjs — via Puppeteer CDP, needs a running browser
scripts/douban-extract.mjs — generates a browser console script for manual extraction

2. Incremental Sync (daily, via RSS)

Run scripts/douban-rss-sync.mjs — no login needed.

node scripts/douban-rss-sync.mjs

Setup: Set environment variables:

DOUBAN_USER (required): Douban user ID
DOUBAN_OUTPUT_DIR (optional): Output root directory, default ~/douban-sync

Recommended: Add a daily cron job for automatic sync.

Output Format

Four CSV files per user in the output directory:

douban-sync/
└── {user_id}/
    ├── 书.csv
    ├── 影视.csv
    ├── 音乐.csv
    └── 游戏.csv

CSV columns:

title,url,date,rating,status,comment
"书名","https://book.douban.com/subject/12345/","2026-01-15","★★★★★","读过","短评内容"

status: 读过/在读/想读, 看过/在看/想看, 听过/在听/想听, 玩过/在玩/想玩

Deduplication

Both full export and RSS sync deduplicate by Douban URL — safe to run multiple times.
