When trying to optimise our applications, one of the first things we look to is caching. Caching involves storing data in a high performance store (many times temporarily) so such data can be retrieved faster at a later time. Redis is an efficient key-value data store that has become very popular for caching. One of the things that makes Redis a good choice is the number of data structures it supports — such as strings, hashes, lists, sets, and so on. This gives us some flexibility!
- Built a Node.js app from scratch,
- Provisioned a Redis server using the Manifold RedisGreen service,
- Connected to the Redis server, and
- Saved data to, and retrieved data from the Redis store using the node redis client.
- Assumed you have 8 >= Node.js and Redis installed
- Run redis server (If not then run
docker run --name redis -p 6379:6379 -d redis) - Now clone the repository
https://github.com/shamrat17/node-app-with-redis-cache.git - Hit
cd node-app-with-redis-cache - Install all dependency
npm install - Start server
npm start
Open you browser and go localhost:5000 you might see somethings like
Now select date and press Get rates button. You will see it takes some moments to get the result from server
After getting response hit again Get rates button and watch how faster it retrives
