In a file app.js, create and save the following server-creation code: // app.js const http = require( 'http') It provides the interaction between users and your application.Ĭreating and starting a server is easy with Node.js's built-in http module. This simply means creating a new record in a database.Did you know that there are multiple ways to start a Node.js server and keep it running? In this post, we will explore various ways to start an HTTP Node server.Ī Node.js server makes your app available to serve HTTP requests. Let's quickly see some examples of these operations. These are the four fundamental options with which you can perform any sort of data manipulation in a database.

Restrict values if you can, using enums.ĬRUD means Create, Read, Update and Delete.

You should at least know about your database names and collections in your codebase. Although Mongoose can automatically give a collection name based on the name of model ( Completed here, for example), this is way too much abstraction in my opinion. But on a large scale they can really help you to speed up your queries a lot. Indexes are a broad topic, so I will not go into depth here. unique property can also be added within a schema.

Plus the free validation is super cool, too. This can be a huge pain saver for you if you don't use a static type checking system like TypeScript to assist you with correct property names while creating an object.

Try to keep required: true on all fields which are required.

A few interesting things you should note here: This is one trimmed down example directly from codedamn's codebase.

How to connect Mongoose + MongoDBįirstly, let's quickly see how you should connect to your MongoDB database in 2020 with Mongoose: nnect(DB_CONNECTION_STRING, )Ĭonst model = mongoose.model('Completed', CompletedSchema) Similarly, with Mongoose, you can limit your surface area of lower level API access, but unlock a lot of potential gains and good DX. Plus, for the most part you don't need to have the power C gives you to implement websockets. The Python example would be much easier and faster for you as a developer to implement with higher productivity.Ĭ might be more efficient, but it'll come at a huge cost in productivity/speed of development/bugs/crashes.

Sometimes it boosts productivity 1000x+ because you never really need to have full access to the underlying API anyway.Ī good way to think about it is you technically create a realtime chat app both in C and in Python. But that doesn't necessarily mean it is bad. The general rule of thumb with abstractions (the way I understand) is that with every abstraction you lose some low-level operation power.

HOW TO START MONGODB SERVER FOR NODE JS DRIVER

Mongoose is an abstraction over the native MongoDB driver (the npm package I mentioned above). You need to reduce your surface area of bugs and screw-ups you can make in your code. More power means more surface area to get things wrong. Now remember, the MongoDB driver is responsible for connecting and abstracting the low level communication request/responses from you – but this only gets you so far as a developer.īecause MongoDB is a schemaless database, it gives you way more power than you need as a beginner. MongoDB driver is available as an npm package here. MongoDB server listens on a TCP socket (usually), and your Node.js process can connect to it using a TCP connection.īut on the top of TCP, MongoDB also has its own protocol for understanding what exactly the client (our Node.js process) wants the database to do.įor this communication, instead of learning the messages we have to send on the TCP layer, we abstract that away with the help of a 'driver' software, called MongoDB driver in this case.

You have a Node.js script running (as a process).

You have a database server (MongoDB community server, for example).

To understand why we need Mongoose, let's understand how MongoDB (and a database) works on the architecture level. You can also find a free course on Mongoose + MongoDB + Node.js here. If you have very little experience with Node.js/JavaScript or the back end in general, this is probably a good place to start. Therefore I assume you have some experience with JavaScript (and Node.js) already. This article is one of the part codedamn's backend learning path, where we start from backend basics and cover them in detail. In this article, we'll review some of the best practices to follow when you're setting up MongoDB and Mongoose with Node.js. And it has a great community and ecosystem. MongoDB is undoubtedly one of the most popular NoSQL database choices today.
