We use it on our production system to store arbitrary data which does not have hard schema, nor needs acid or transactions support.īut seeing code examples / tutorial on the internet that 'teaches' you how to code a store or a financial application and it uses Mongo. If you need schema-less, non-acid transaction lacking storage - Mongo is great. Connect MongoDB cloud using Node.js npm init -y npm install mongodb express cors dotenv -save const dbo require(./db/connection) require(dotenv). const express require ('express') const mongoose require ('mongoose') Now, transfer the contents of Express into a new constant called app. And in this file, let's add Express and Mongoose, and run the file. This will be the entry point for our application. It looks like 'NodeJS + MongoDB' is some cool 'buzzword' and its cool to use node with mongo and all the cool people do it. After they have finished installing, create one file named index.js. They even use it when ACID compliance is needed. They use MongoDB in cases when transactions among multiple documents are needed and Mongo can not provide it. People use MongoDB which is SCHEMA-LESS by design, but implicitly force a schema on it by using mongoose for example. And I'm afraid that one day it will become the same garbage as PHP today. Node is fast, scale able, advocates good practices by providing test covered npm modules, automatic build tools and high quality code. (Note: this is slowly improving right now). I come from PHP world, and PHP world is full of crap with bad design patterns, examples that still suggest to use not safe or deprecated functionality (like mysql_* function family), lack of tests and automation - thus producing low quality programmers.

Every code examples you look at on the internet uses Mongo, even though Mongo neither ACID compliant nor have support for transactions on multiple documents. There is even a 'term' for such stack - MEAN (Mongo, express, angular, node). router.Since the day I've introduced my self to NodeJS, all tutorials exclusively used MongoDB. But before that, this function needs to be asynchronous to work. Then it will generate a package.json file in that folder. This command will ask you for various details, such as the name of your project, the author, the repository, and more.

In an empty folder, run the following command: npm init If not, go to to download and install it. We will create endpoints for creating data, reading data, updating data, and deleting data (basic CRUD operations).īut before we get started, make sure you have Node installed in your system. In this article, we'll build a RESTful API using Node, Express, and MongoDB.
