An implementation of a rate limiter to control the rate of requests to end users based on custom rules.
The application is built with Node.js, NestJS, TypeScript, Knex and Docker.
During the development, I've tried to follow the Hexagonal Architecture, so the application is divided into some layers
Also, I've tried my best to use TDD as much as possible, so I've created a test suite with Jest
$ yarn install$ yarn knex migrate:latest$ yarn knex seed:runThis will create some rules for testing.
