Caching can be implemented using in-memory solutions like Redis or in-process caching with libraries such as node-cache
. This helps reduce load times and improve performance by storing frequently accessed data. Example using Redis for caching:
const redis = require('redis');
const client = redis.createClient();
client.set('key', 'value', redis.print);
client.get('key', (err, reply) => {
console.log(reply); // Will print 'value'
});
