nodejs redis

To add Redis to a Node.js application, you will need to follow these steps:

Install the Redis module: First, you need to install the Redis module in your Node.js application using npm. Run the following command in your terminal:

npm install redis

Require Redis module: Once the Redis module is installed, you can require it in your Node.js application using the following line of code:

const redis = require("redis");

Create a Redis client: Next, you need to create a Redis client using the createClient() method:

const client = redis.createClient();

Use Redis client to store and retrieve data: You can use the Redis client to store and retrieve data. For example, to store a value in Redis, use the set() method:

client.set("key", "value", redis.print);

To retrieve a value from Redis, use the get() method:

client.get("key", function(error, result) {
  if (error) {
    console.error(error);
  } else {
    console.log(result);
  }
});

That’s it! You have successfully added Redis to your Node.js application.
