Lord1Egypt 小红书自动发布 (Xiaohongshu Auto-Publish)
Publish image+text posts to Xiaohongshu via browser automation. No API key needed — uses CDP to control an already-logged-in browser.
Prerequisites
- playwright-core installed:
npm install -g playwright-core - A Chromium browser running with CDP (remote debugging) enabled
- Logged in to
creator.xiaohongshu.comin that browser
For OpenClaw users: the managed browser (profile="openclaw") provides CDP automatically at http://127.0.0.1:18800.
Quick Start
node scripts/publish.js \
--title "你的标题（20字以内）" \
--body "正文内容（1000字以内）" \
--images cover.png,slide2.png,slide3.png \
--hashtags "AI绘画,独立开发" \
--cdp-url http://127.0.0.1:18800
This auto-publishes the post. Add --dry-run to preview without publishing.

Workflow
- Connects to browser via CDP
- Navigates to
creator.xiaohongshu.com/publish/publish - Clicks "上传图文" (upload images) tab
- Uploads all images via file input
- Sets title (native input value setter for React compatibility)
- Sets body (innerHTML on TipTap/ProseMirror editor)
- Takes preview screenshot
- Optionally clicks "发布" (publish) button
Tips
- Title: Keep under 20 chars. Hook-style titles work best (e.g. "用AI画塔罗牌也太好看了吧")
- Body: Short paragraphs with emoji. 小红书 is scroll-heavy — hooks > long text
- Images: First image is the cover. Use 3:4 ratio (1242×1660) for best display
- Hashtags: Add 3-5 relevant tags for discoverability
- Preview first: Always run without
--publishfirst to verify via screenshot
Troubleshooting
| Problem | Solution |
|---|---|
| "Cannot connect to CDP" | Ensure browser is running with remote debugging. For OpenClaw: check openclaw browser status |
| "Redirected" / not logged in | Open the browser manually and log in to creator.xiaohongshu.com |
| Title input not found | Page may not have loaded. Increase wait time or check network |
| Images fail to upload | Ensure images are PNG/JPG/WebP and under 20MB each |
XHS Content Best Practices
- Short hook titles > descriptive titles (20 char limit forces creativity)
- 3-6 images per post is the sweet spot
- First image = cover — make it eye-catching
- Short punchy paragraphs with emoji — not walls of text
- End with a question to drive comments
- 3-5 hashtags for discovery, more feels spammy
