Your connection string will vary based on your installation. Next, we will add a simple class with a method that connects to the database. The Mongoose syntax in this article is specific to Mongoose v5 and beyond.

The above install command will install the latest version of the libraries. Let’s install Mongoose and a validation library with the following command: npm install mongoose validator Let’s go to the project folder and initialize our project npm init -y Fire up your favorite IDE, create a blank project, and let’s get started! We will be using the limited ES6 syntax in Node, so we won’t be configuring Babel. I am using Visual Studio Code, Node 8.9, and NPM 5.6. Let’s navigate through some of the basics of Mongoose by implementing a model that represents data for a simplified address book. Install Mongo using Docker if you prefer to use docker.Create a free sandbox database subscription on mLab.
Download the appropriate MongoDB version for your Operating System from the MongoDB Website and follow their installation instructions.You can choose from one of the following options (we are using option #1 for this article): Getting Started Mongo Installationīefore we get started, let’s setup Mongo. ‘Models’ are higher-order constructors that take a schema and create an instance of a document equivalent to records in a relational database. A Mongoose ‘schema’ is a document data structure (or shape of the document) that is enforced via the application layer. While Mongo is schema-less, SQL defines a schema via the table definition. ‘Fields’ or attributes are similar to columns in a SQL table. While a SQL row can reference data in other tables, Mongo documents usually combine that in a document. ‘Documents’ are equivalent to records or rows of data in SQL. ‘Collections’ in Mongo are equivalent to tables in relational databases.
Relational Tables in SQL Terminologies Collections This is one of the advantages of using NoSQL as it speeds up application development and reduces the complexity of deployments.īelow is an example of how data is stored in Mongo vs. It means you can store JSON documents in it, and the structure of these documents can vary as it is not enforced like SQL databases. MongoDB is a schema-less NoSQL document database. Object Mapping between Node and MongoDB managed via Mongoose

It manages relationships between data, provides schema validation, and is used to translate between objects in code and the representation of those objects in MongoDB. Mongoose is an Object Data Modeling (ODM) library for MongoDB and Node.js. By Nick Karnik Introduction to Mongoose for MongoDB
