Overview

Repository destinated to study app cache strategies, such as cache aside, using Redis.

Redis is a powerful tool for caching data in memory, which can increase application benchmark when consuming

By default, redis is set up with some default credentials, so when app is live for production, it is necessary to provide some configurations in redis.conf such as user, password and other settings like maxmemory allocation

Used Technologies

• Redis 7.2.4-alpine
• Typescript 5.4.3
• Node v20.12.0

Strategy Perfomance Comparison

Cache Strategy: 1ms

HTTP Strategy: 567ms

Cache aside strategy can be even more rewarding when applied into massive recurrent data

Getting Started

1. Install dependencies

npm install

2. Run redis with docker

You can connect to redis with a different instance instead of running a docker, just be sure to let it running in redis://localhost:6379

docker compose up -d --build

3. Run application

npm run start
