![]() ![]() This is more than adequate for a simple app with a handful of users. It has a free plan which provides a single database with 512MB of storage running on a shared virtual machine. The quickest way to get up and running with Mongo is to use a service such as MongoDB Atlas. If you’ve never worked with Mongo before, you might like to check out our beginner-friendly introduction to MongoDB. MongoDB is a document database which stores data in flexible, JSON-like documents. We’ll be making quite extensive use of npm throughout this tutorial, so if you’re in need of a refresher, please consult A Beginner’s Guide to npm - the Node Package Manager. Npm is a JavaScript package manager which comes bundled with Node, so no extra installation is necessary here. Otherwise, grab the correct binaries for your system from the link above and install those. If you fancy going the version manager route, please consult our Install Multiple Versions of Node.js Using nvm quick tip. For example, it negates potential permission issues which would otherwise see you installing packages with admin rights. There are various advantages to using a version manager. This is a program which allows you to install multiple versions of Node and switch between them with ease. While that works, I would suggest that you use a version manager instead. ![]() Many websites will recommend that you head to the official Node download page and grab the Node binaries for your system. I won’t go into depth on the various installation instructions, but if you have any trouble getting set up, please visit our forums and ask for help there. A note about request and response objectsīefore we can start coding, we’ll need to get Node, npm and MongoDB installed on our machines.Using the layout file from the child template.Installing Pug and integrating it into the Express app.Checking the database connection using Compass.Checking that everything is installed correctly.It will, however, be suitable for those people who feel reasonably confident with the JavaScript language and who are looking to take their first steps in Node.js. If that’s the kind of thing you’re after, look here. These include routing, templating, dealing with forms, interacting with a database and even basic authentication. Starting from the ground up, I’ll demonstrate how to build a no-frills web app using Node.js, but instead of focusing on the end result, I’ll focus on a range of things you’re likely to encounter when building a real-world app. In this tutorial, I’m going to take a slightly different approach. This means that, by the time you’ve finished, you’ve built something nice and shiny, but you also have relatively few takeaways that you can apply to your next project. Once you get beyond the “Hello, World!” tutorials, much of the material out there has you copy-pasting code, with little or no explanation as to what you’re doing or why. If you’re just getting started with Node.js and want to try your hand at building a web app, things can often get a little overwhelming. ![]()
