Official Installation Docs

The following repository contains the performance of api using redis . We generally see the response time of request with both caching and no-caching

Installation Steps:

git clone https://github.com/uchiha-vivek/Redis-concepts.git

cd Redis-concepts

Install the dependencies

npm install

Run the file

node index.js

How to test :

Once the server is running

Call cached endpoint (first time hit's miss)

curl "http://localhost:3000/photos?albumId=1"

call cached endpoint again(hits)

curl "http://localhost:3000/photos?albumId=1"

Invoke no-cache endpoint

curl "http://localhost:3000/photos-nocache?albumId=1"

Test and check the metrics:

curl "http://localhost:3000/metrics"
