LeetUp

A streamlined LeetCode practice environment with automatic problem setup and multi-language support.

Features

• Fetch LeetCode problems automatically from API
• Generate problem descriptions, hints, and test scaffolding
• Support for several programming languages (Go, PHP)
• Run tests with a single command

Usage

1. Start the environment

docker-compose up -d

2. Setup a new problem

docker exec leetup setup <language> <problem-slug-or-link>

Examples:

docker exec leetup setup go two-sum
docker exec leetup setup php https://leetcode.com/problems/two-sum/

3. Generate unit tests using Claude Code custom command

After setting up a new problem, generate comprehensive unit tests (in Claude Code terminal):

/leetup-tests <problem-directory>

Example:

/leetup-tests 1-two-sum-GO

4. Implement your solution in the solution.<lang> file

5. Run tests

docker exec leetup check <problem-directory>

Example:

docker exec leetup check 1-two-sum-GO

6. Generate progressive hints

If stuck, generate a series of progressive hints to guide you through the problem (in Claude Code terminal):

/leetup-hints <problem-directory>

Example:

/leetup-hints 3-longest-substring-without-repeating-characters-GO

7. Review your solution

Get detailed feedback on your completed solution including complexity analysis and optimization suggestions (in Claude Code terminal):

/leetup-review <problem-directory>

Example:

/leetup-review 1-two-sum-GO
