Usage

Step 1: Scrape LeetCode Problems

1. Go to LeetCode Top Interview 150
2. Open DevTools Console (F12)
3. Copy and paste the contents of scraper.js into the console
4. Press Enter and wait for the download

This will download leetcode_top150.json with all the problems.

Step 2: Import to Notion

node import.js

This will:

• Create a new Notion database (or update existing one)
• Import all problems with proper categorization
• Set up tracking fields for your study progress

Database Schema

The created Notion database includes these properties:

• Name - Problem title
• URL - LeetCode problem link
• LeetCode ID - Problem number
• Slug - URL slug for deduplication
• Difficulty - Easy/Medium/Hard
• Topic - Problem category (Array, String, etc.)
• Status - Not Started/In Progress/Completed/Reviewed
• Claimed by - Who's working on it
• Completed by - Who finished it
• Date Started - When work began
• Date Completed - When finished
• Time Spent - Minutes invested
• Attempts - Number of tries
• Notes - Personal notes
• Solution Link - Your solution repository
• Tags - Custom tags
• Priority - High/Medium/Low

Usage Tips

For Study Groups

• Use "Claimed by" to assign problems
• Use "Completed by" to track who finished
• Filter by person to see individual progress

Views to Create

• My Problems - Filter by your name in "Claimed by"
• By Topic - Group by Topic property
• By Difficulty - Filter Easy/Medium/Hard
• Progress Board - Kanban view grouped by Status

Workflow

1. Claim a problem by adding your name to "Claimed by"
2. Set Status to "In Progress" and Date Started
3. When done, set Status to "Completed", add Date Completed
4. Add your name to "Completed by"
5. Optionally add time spent and notes

Re-running

The import script is idempotent - you can run it multiple times without creating duplicates. It matches problems by slug and URL.
