LeetCode API

The API for retrieving your Leetcode Solved Questions stats

About

Leetcode - the worlds leading platform for for coding and algorithmic problems.

I discovered that there are not many APIs that allow you to enter a username and see your Leetcode Stats and as a Leetcode advocate I decided to tackle this problem.

Technologies Used

• Springboot backend
• Thymleaf for the view/front-end
• GraphQL
• Postman for testing leetcode's graphql endpoint

https://leetcode.com/graphql - uses Leetcode's GraphQL endpoint to retrieve data

Getting Started

• Clone the repository
• Run the following command in the project directory:
  • /mvnw spring-boot:run
• Navigate to http://localhost:8080/leetcode/stats

Project Structure

• LeetcodeApiApplication.java - Entry point of the Spring application
• LeetcodeController.java - Handles request relating to Leetcode stats and returning the response
• LeetcodeData.java - Plain old Java objects (holder of the data passed by the Controller to be displayed on a View)
• LeetcodeService.java - Service class that calls Leetcode's graphQL endpoint, converts data to POJO and returns to controller
• schema.graphqls - GraphQL schema
• form.html - Thymleaf template for the view

Further Work

• Improve front-end UI
