💣 Learning Load & Stress Tests 💣

Introduction

• A side project I created to learn and improve my skills in:

  • k6
  • Load Tests & Stress Tests
  • Load Balancer
  • Concurrency & Parallelism
  • A.C.I.D and Transactions CRUD operations
  • Performance Benchmarks using diferent technologies and databases

• Technologies:

  • NodeJS
  • Bun
  • ElysiaJS
  • Fastify
  • PM2 Process Manager
  • VineJS Data Validator
  • TypeScript
  • MongoDB
  • Mongoose ODM
  • PostgreSQL
  • Prisma ORM
  • Redis
  • Docker
  • JSON-RPC
  • NGINX
  • GraphQL
  • Serverless Framework
  • AWS
    • Lambda
    • DynamoDB
    • API Gateway

ToDo

• API using MongoDB
• API using PostgreSQL
• API using Serverless Framework and DynamoDB
• API using Load Balancer
• API using RPC
• API using GraphQL
• API using REST
• API using Redis

Prerequisites

• Install k6: https://k6.io/docs/get-started/installation/
• Install Bun: https://bun.sh/docs/installation
• Install NodeJS >= v20: https://nodejs.org/en/download/package-manager
• Install Docker & Docker Compose: https://docs.docker.com/engine/install/
• Have an AWS Account: https://aws.amazon.com/free/

Up API Servers

• Enter the API folder you wanna test and follow README.md instructions

Tips

• K6 Reports:
  • To see k6 tests reports, up a server in the root of this project
  • And go for example: http://localhost:3000/k6-tests/reports/rest-postgres-api-load-test-signup.html
• POST /signup:
  • Tests are made using fake data, to not repeat the same signup
• POST /checkout:
  • Check to increase ou add more stock units as you want in database while you are testing.

⚠️ Doing ⚠️

• Finish REST Postgres API Tests
• Finish GraphQL Redis API Tests
• Finish JSON-RPC MongoDB API Tests
• Finish Serverless API Tests
• Finish NGINX Load Balancer API Tests
