Many people ask: how do I share mongoose in Nodejs to establish a database connection, and then use this database connection elsewhere in this application?Many foreign postings have been discussed, but the relative dullness of the country, the popularity of technology and the degree of enthusiasm for technology are also evident.Anyway .... Back to TopicThe following example shows you how to make a database connection and use it elsewhere in the progra

Label:In traditional projects, we often use caching to optimize database reads, such as in Java, where we take advantage of Spring's AOP capabilities to increase caching operations before reading and writing databases. Similar problems still exist in node and MongoDB projects, this article refers to the Mongoose-redis-cache plugin. Https://github.com/conancat/mongoose-redis-cache The plugin is not perfect,

MongoDB is a JavaScript-based database, stored in JSON format, and node is a JavaScript based environment (library), so the pairing of node and MongoDB can reduce the time and space overhead associated with data transformations.
