Overview

Leetcode-Bot consists of two Lambda functions: Fetcher and Sender. The Fetcher regularly checks Leetcode APIs for new submissions by the specified users, sending them to an SQS queue. It also stores the timestamp of the last sent submissions in a DynamoDB table. The Sender consumes submissions from the SQS queue and sends them to a Discord channel using a webhook.

Getting Started

Setting up Leetcode-Bot is a breeze! Just follow these simple steps:

Prerequisites

Make sure you have the following installed:

• Rust
