termleet

Revise LeetCode problems (with C++ solutions from walkccc) directly in your terminal — no browser required.

Preview

Installation

npm install -g termleet

Requires Node.js 18 or later.

Usage

dsa                        # random problem + C++ solution
dsa --difficulty=medium    # filter by difficulty (easy | medium | hard)
dsa --no-solution          # show the problem only

Run locally during development

# from repository root
npm install
npm install -g .

# run the globally linked CLI
dsa

If dsa can't find a walkccc solution after several attempts, it falls back to showing a LeetCode problem without the solution block so you can continue practicing.

dsa renders markdown directly in terminal using:

• marked-terminal for markdown structure
• cli-highlight for C++ syntax highlighting

The output is markdown-friendly.

How it works

1. Fetches the full LeetCode problem list from the public endpoint (https://leetcode.com/api/problems/all/).
2. Picks a random free problem.
3. Fetches problem details without login:
   • First tries LeetCode's public GraphQL endpoint (https://leetcode.com/graphql/).
   • If GraphQL is blocked/rate-limited/unavailable, falls back to the public problem page (/problems/<slug>/description/) and extracts description data from embedded JSON.
4. Fetches the corresponding C++ solution from the walkccc/LeetCode repository.
5. If walkccc has no solution for the chosen problem, a different problem is tried automatically.
6. During retries, unavailable slugs are tracked only in-memory for the current run (no local persistence file).
7. Renders markdown to styled terminal output.

Development

# run unit tests (no network required)
npm test
