Mongoose VS node

To manage user auth we need to create a user account - identification. So, let's install mongoose and jsonwebtoken to handle JWT authentication - an alternative to creating a user session when a user logs in

If your application uses MongoDB's Node.js driver or Mongoose ODM, occasionally you may observe errors such as querySrv ECONNREFUSED _mongodb._tcp.cluster0.abcde.mongodb.net or Error: querySrv ETIMEOUT _mongodb._tcp.cluster0.abcde.mongodb.net being thrown. The MongoDB Atlas documentation outlines several methods to troubleshoot connection issues, including how to handle "Connection Refused using SRV Connection String" scenarios, but why does this happen in the first place?

If you use Sequalize, TypeORM or for MongoDB, we have Mongoose these types of ORM tools, then you are safe by default because these help us against the SQL query injection attacks by default.

Mongoose

Now that we have created a new MongoDB deployment and saved the connection string in .env file, we would enter the code below to connect to MongoDB database through mongoose. Then, open db.js and enter this code:

Mongoose is a popular JavaScript library used with MongoDB, a NoSQL database. It provides an elegant and user-friendly way to interact with MongoDB from Node.js applications. Mongoose offers several key benefits:

To simplify this process, Cerbos developers have come up with adapters for popular Object-Relational Mapping (ORM) frameworks. You can check out for more details on the query plan repo - which also contains adapters for Prisma and SQLAlchemy - as well as a fully functioning application using Mongoose as its ORM.

After importing the mongoose module, use the [mongoose.connect()](https://mongoosejs.com/docs/api/mongoose.html#mongoose_Mongoose-connect) function to connect to the database. The first argument is the connection string, and the second argument is an object that contains the options, which are used to configure the connection. The above code logs the message, MongoDB connection is established successfully! 🎉, once the connection is successful.

Helmet helps “sanitise” the input, which might not have come from the UI directly. Mongoose is what is known as an Object Document Modelling (ODM), which defines a structure (schema) for the stored data, making it easier to manage in Express. These additions have been omitted from our example stack purely to simplify the tutorial and focus on the fundamental tiers and interfaces.

Before starting a new project in react, you need to make sure that you have NodeJS install on your system. You can download the latest version of node at https://nodejs.org. Follow the instructions on the node website to do the installation.

Installing Node.js: Download and install Node.js from nodejs.org. Choose the version recommended for most users, unless you have specific needs that require the latest features or earlier compatibility.

You should have Nodejs installed on your laptop and if not, check the Node.js official website, and download/ install the latest and stable release.

Node.js

To install and run Ember.js, you'll need to follow these steps: Install Node.js and npm (Node Package Manager) on your computer. You can download the latest version of Node.js from the official website. Once Node.js and npm are installed, open a terminal window and run the following command to install the Ember.js command line interface (CLI):

To get involved in the Node.js developer community, you can join community discussions or begin with learning if you’re new. The community discussion houses a GitHub list of issues related to Node.js' core features. If you want to chat in real time about Node.js development, there are Slack groups, and you can still connect with IRC clients or web clients when using the browser. Node.js has a calendar for public meetings.
