There is so much that you can learn about on their official documentation. In this article, we have shown how you can use Redis with nodejs with a basic implementation.

We can see that the time taken for the response is reduced from 1563ms to 33ms which is a huge change. Let us run this code and see the response on the postman to see the results. In our case, searchtext is the key and the data from JSON placeholder API is its value. In case of cache not being there, the server will hit the external API and cache it for subsequent requests.Ĭtex() is the function that takes a key, its value, and duration for the validity of cache as an input. Install To install node-redis, run: npm install redis Connect Connect to localhost on port 6379. See Getting started for Redis installation instructions. node-redis requires a running Redis or Redis Stack server. Inside the endpoint, we make Redis cache the data against a specific key and return the response if the appropriate cached data is available without hitting our external API. node-redis is a modern, high-performance Redis client for Node.js. Firstly, we have initialized the Redis client on the port of choice. Create a new NodeJS project: First, create a blank NodeJS. Let’s understand how to make the connection of NodeJS to Redis. The NodeJS and Redis must be installed on your machine in order to make a connection with the Redis. Let us explain what is happening in the above piece of code. In this tutorial, you will learn how to establish a connection between NodeJS and Redis using the node-redis library. Const searchtext = Ĭlient.get(searchtext, async (err, data) => `)
