We will create a project named expressjs-tutorial. All you have to do is type express and then the name of the project that you want to create. Next up, let’s go ahead and create a new Express project using our newly installed Express Generator. Just type npm install -g express-generator at your command line, and this will install it for you. The first thing we need to do is to install the express generator module on our system. The Express framework, created by TJ Holowaychuk, provides convenience methods and syntactic sugar for many common tasks that would otherwise be tedious and redundant. With Express, configuring routes becomes a breeze. Express builds on Node and offers many tools that make working with Node easier. The repetitive tasks like parsing urls and setting up manual routing can be handled by the framework. Express will allow you to focus on your business logic and the needs of your application. This is why we are now moving on to taking a look at Express.js. Well guess what? Like most other things in software development, what you are trying to do has likely been done already with a stable and tested solution. This is prone to errors, is likely insecure, and just plain lots of work. Working with Node.js in it’s pure form requires that we write everything all on our own. In addition, if we wanted to add multiple routes, it would not scale that well. If you take a look at the code in the routes tutorial, you’ll notice that it is kind of a lot of work to just set up some routes on our own. We learned about what Node.js is, how to write and read data from the file system, handled some requests and responses, as well as set up our own basic routing system. So at this point we have taken some time to get used to working with Node.js at a very basic level. What is Express.js and why do we want to use it? Let’s take a look at how the complete beginner can get up and running with Express.js right away. Thankfully, this is made pretty easy by the fact that there is a dedicated tool to create a new Express project automatically called Express Generator. In this Express beginner tutorial, we can download and install Express.js to our system and see how to get a super basic skeleton application set up and configured.
