Other-Task Utilities

A collection of web scraping and data analysis utilities for Chinese social media platforms and macro-economic data sources.

📋 Table of Contents


Overview

This repository contains standalone scraping and analysis tools for:

  • Social Media: Twitter/X lists, Weibo groups and user profiles
  • Financial Data: Eastmoney futures market data
  • Macro Economics: Chinese macro-economic indicators from official sources
  • Content Analysis: LLM-powered analysis of collected data

All scrapers use browser automation (Patchright - Playwright fork) with persistent browser profiles to maintain authentication sessions.


Quick Start

Installation

# Install dependencies
npm install

# Create browser profile for authenticated scraping
npm run browser 1

# Run your first scraper
npm run scrape:twitter

Prerequisites

  • Node.js >= 14.0.0
  • Chrome browser installed

Available Tasks

1. Twitter/X Scraper

Scrapes tweets (text + images) from X lists with support for retweets and quote tweets.

Script: other-task/twitter-task/scrape-twitter-list.js

NPM Commands

# Basic usage (default: 5 tweets, profile 1)
npm run scrape:twitter

# With custom arguments
npm run scrape:twitter -- --count 10 --since today
npm run scrape:twitter -- --profile 2 --since 24h
npm run scrape:twitter -- --no-cache  # Force regenerate

Direct Command

node other-task/twitter-task/scrape-twitter-list.js [options]

Parameters

Parameter Type Default Description
--profile <id> number 1 Browser profile ID to use
--count <n> number 5 Number of tweets to scrape
--since <when> string - Time filter (see below)
--url <url> string Built-in Custom X list URL
--output-dir <dir> string twitter-YYYY-MM-DD/ Output directory
--headless flag false Run browser in headless mode
--scroll-delay <ms> number 2000 Delay between scrolls (ms)
--no-cache flag - Force regenerate (ignore cache)
--help flag - Show help message

Time Filters (--since)

  • today - Start of today (midnight)
  • yesterday - Start of yesterday
  • 24h, 12h, 2h, 1h - Relative hours ago
  • 2d, 7d - Relative days ago
  • 30m, 90m - Relative minutes ago
  • YYYY-MM-DD - Specific date (midnight)

Note: Using --since removes the default 5-tweet limit. Add --count N to cap results.

Examples

# Latest 5 tweets (default)
npm run scrape:twitter

# All tweets from today
npm run scrape:twitter -- --since today

# Last 24 hours, max 20 tweets
npm run scrape:twitter -- --since 24h --count 20

# Since specific date
npm run scrape:twitter -- --since 2026-02-09

# Custom list URL with profile 2
npm run scrape:twitter -- --url https://x.com/i/lists/YOUR_LIST_ID --profile 2

# Show browser window (non-headless)
npm run scrape:twitter -- --no-headless

# Force regenerate cached data
npm run scrape:twitter -- --no-cache

User Timeline Scraper

For a single X profile, use:

# Default: https://x.com/aimikoda, down to 2026-02-07 inclusive
npm run scrape:twitter:user

# Resume is enabled by default through crawl-state.json
npm run scrape:twitter:user -- --profile 2

# Start over
npm run scrape:twitter:user -- --fresh

# Custom profile / cutoff
npm run scrape:twitter:user -- --url https://x.com/aimikoda --handle aimikoda --until 2026-02-07

# Optional: also download images
npm run scrape:twitter:user -- --download-images

Output defaults to other-task/twitter-task/twitter-user-aimikoda-2026-02-07/. Each post is saved as blog-0001-<tweet-id>/content.md; progress is recorded in crawl-state.json so interrupted runs skip previously saved post URLs.

Output Structure

twitter-2026-03-03/
  blog-1/
    content.md        # Tweet text with metadata
    image-1.jpg       # High-res images

# Resume interrupted workflow
npm run workflow:macro-news -- --resume

# Clear state and restart
npm run workflow:macro-news -- --no-cache

# Show workflow structure without running
npm run workflow:macro-news -- --dry-run

# Custom concurrency and retries
npm run workflow:macro-news -- --concurrency 3 --retries 3

# Skip LLM analysis
npm run workflow:macro-news -- --no-llm

Workflow Steps

Each data source creates a pipeline:

  1. fetch-page - Scrape source URL
  2. analyze - LLM analysis of content
  3. generate-report - Compile final report

State Management

State file: output/workflow-state.json

  • Automatically saves progress after each step
  • --resume continues from last completed step
  • --no-cache clears state for fresh start
  • Each step tracks: status, output, error, retry count

Output

  • State: output/workflow-state.json (progress tracking)
  • Report: output/macro-news-report-YYYY-MM-DD.md (final report)

Cache Behavior

🔄 State-based resume (not traditional cache):

  • Uses workflow-state.json to track step completion
  • Auto-resumes if state exists
  • --resume explicitly continues from state
  • --no-cache clears state for fresh start

Browser Profiles

All scrapers (except Eastmoney) use persistent browser profiles to maintain login sessions.

Creating a Browser Profile

# Launch browser with profile ID
npm run browser 1

# Or directly
node launch-browser.js 1

This opens Chrome with:

  • Persistent storage at browser-profiles/browser-1/
  • Interactive welcome page with login instructions
  • No auto-close (stays open for manual login)

Steps:

  1. Run npm run browser 1
  2. Log in to required platforms:
    • Twitter/X: Visit x.com and log in
    • Weibo: Visit weibo.com and log in
  3. Close browser when done
  4. Your session is saved!

Using Different Profiles

# Create multiple profiles
npm run browser 1  # Profile 1
npm run browser 2  # Profile 2
npm run browser 3  # Profile 3

# Use in scrapers
npm run scrape:twitter -- --profile 1
npm run scrape:twitter -- --profile 2
npm run scrape:weibo -- --profile 3

Use cases:

  • Multiple accounts
  • Different login sessions
  • Proxy rotation
  • Parallel scraping

Cache Behavior

Each task has optimized cache logic:

Task Cache Strategy Auto-invalidate Override
Twitter Date-based Daily --no-cache
Weibo List Date-based Daily --no-cache
Weibo User ❌ No cache Always fresh N/A
Eastmoney Date + Symbol Daily --no-cache
Macro News Date-based Daily --no-cache
Macro Workflow State resume Manual --no-cache

How It Works

Date-based cache:

  • Output directory/file includes date: twitter-2026-03-03/
  • Scraper checks if it exists before running
  • If exists: Fast exit with cache hit message
  • If not exists: Run scraper normally
  • Next day: New date → automatic invalidation

Symbol-based cache (Eastmoney):

  • Each symbol cached independently
  • ma pp cached → Add eg → Only scrapes eg
  • All cached → Fast exit
  • Use --no-cache to regenerate all

No cache (Weibo User):

  • Always fetches fresh data
  • User posts are frequently updated
  • Ensures accuracy

State resume (Workflow):

  • Not a traditional cache
  • Tracks step completion in workflow-state.json
  • --resume continues from last step
  • --no-cache clears state

Cache Examples

# First run: fresh scrape
$ npm run scrape:twitter
🚀 Launching browser...
✅ Scraped 10 tweets

# Second run: cache hit
$ npm run scrape:twitter
📦 Cache hit: twitter-2026-03-03/ already exists
   Contains 10 blog(s)
   Use --no-cache to regenerate

# Force regenerate
$ npm run scrape:twitter -- --no-cache
🗑️  Clearing existing output
🚀 Launching browser...

Proxy Configuration

(Optional) Configure proxies for browser profiles.

Setup

Create proxy-config.json in project root:

[
  {
    "server": "proxy1.example.com:8080",
    "username": "user1",
    "password": "pass1"
  },
  {
    "server": "proxy2.example.com:8080",
    "username": "user2",
    "password": "pass2"
  },
  {
    "server": "proxy3.example.com:8080",
    "username": "user3",
    "password": "pass3"
  }
]

Usage

Profile index maps to proxy array index:

  • Profile 1 → Proxy 1 (array[0])
  • Profile 2 → Proxy 2 (array[1])
  • Profile 3 → Proxy 3 (array[2])
# Create profile 1 with proxy 1
npm run browser 1

# Scrape with profile 2 (uses proxy 2)
npm run scrape:twitter -- --profile 2

Supported Tasks

Proxies work with:

  • ✅ Twitter scraper
  • ✅ Weibo scrapers (list + user)
  • ✅ Browser launcher
  • ❌ Eastmoney (no profile, no proxy)
  • ❌ Macro news (no profile, no proxy)

Troubleshooting

Not Logged In Error

Error: "❌ Not logged in to X/Weibo"

Solution:

  1. Create/refresh profile: npm run browser <profile-id>
  2. Log in to the platform
  3. Close browser
  4. Run scraper again

Browser Profile Not Found

Error: "❌ Browser profile not found"

Solution:

# Create the missing profile
npm run browser 1  # or 2, 3, etc.

Page Not Loading / Timeout

Symptoms: Scraper hangs or times out

Solutions:

  • Check internet connection
  • Increase scroll delay: --scroll-delay 5000
  • Increase timeout (macro only): --timeout 60000
  • Show browser to debug: --no-headless
  • Check if platform changed page structure

Image Download Failures

Symptoms: Some images missing in output

Causes: Network issues, invalid URLs, rate limiting

Solutions:

  • Scraper auto-retries with fallback URLs
  • Check console output for specific errors
  • Reduce concurrency if rate-limited
  • Increase --scroll-delay to give images time to load

LLM Analysis Failures (Macro News)

Error: "LLM call failed" or missing analysis

Solutions:

  1. Verify .env configuration:

    cd other-task/macro-news-task
    cat .env  # Should show LLM_API_KEY
  2. Check API quota and rate limits

  3. Skip LLM to test scraping only:

    npm run fetch:macro-news -- --no-llm
  4. Test with single source:

    npm run fetch:macro-news -- --source M2_M1_M0

Cache Issues

Problem: Stale cached data

Solution:

# Force regenerate with --no-cache
npm run scrape:twitter -- --no-cache
npm run fetch:macro-news -- --no-cache
npm run scrape:eastmoney -- ma pp --no-cache

Problem: Want to skip cache permanently

Solution: Delete cached output:

# Twitter
rm -rf other-task/twitter-task/twitter-2026-03-03/

# Weibo
rm -rf other-task/weibo-task/weibo-2026-03-03/

# Eastmoney
rm -rf other-task/eastmoney-task/2026-03-03_eastmoney_review/

# Macro news
rm other-task/macro-news-task/output/macro-news-report-2026-03-03.md

Workflow State Corruption

Problem: Workflow can't resume or shows errors

Solution: Clear state and restart

npm run workflow:macro-news -- --no-cache

Or manually:

rm other-task/macro-news-task/output/workflow-state.json
npm run workflow:macro-news

Debugging Tips

  1. Show browser window: Add --no-headless to see what's happening
  2. Check terminal logs: All scrapers print detailed progress
  3. Test with small counts: Use --count 1 for quick tests
  4. Verify platform access: Open URLs manually in browser
  5. Check rate limits: Reduce --concurrency if hitting limits
