![]() It also helps developers build applications with increased performance and high productivity. This allows developers to build applications in the same JavaScript environment they use to create web pages. Node.js is currently the most popular platform for building fast, responsive, and scalable web applications. It incorporates a program interface between JavaScript and the operating system that is non-blocking, allowing it to handle higher requests in less time and with fewer resources. Ryan Dahl first released Node.js in 2009 as an open-source project on GitHub. Node.js is gaining popularity due to its performance, scalability, and cross-platform capabilities, making it even more ideal for developing web applications that run on multiple platforms. Node.js is an open-source JavaScript runtime environment that allows developers to write server-side code using JavaScript. Then came Node.js, which is currently very popular and has built thousands of websites and applications that can run on multiple platforms. Therefore, the developers are considering whether Javascript can be run on the server side so that web developers only need to master one programming language, namely Javascript. But all of that can only be run on the client or browser side web developers must still understand programming on the server side, such as PHP, ASP, and others. In that era, AJAX (Asynchronous JavaScript and XML) emerged, and many JavaScript libraries to make programming more accessible, such as Jquery, Angular JS, and others. Javascript is run in the browser to manipulate web pages, and maybe your website's backend is PHP and MySQL. In short steps you just set up a complete web development environment.If you are an old web programmer, you are familiar with JavaScript to beautify or make the web pages you build more dynamic. If you want to install express locally to the application you first would change to the application directory and then issue a:Īs mentioned, this will create a “node_modules” folder (if not already there) and place the express module in it. In short, for installing express globally you would do: In order to install a module globally you simply append the “-g” flag to your install statement. Local modules are installed in the “node_modules” within your application folder whereas global modules will be installed in a global “node_modules” folder (within the path of nodejs itself). With every Nodejs application you can install modules for the application only or install them globally, so they are available to all applications. But before doing so, you should understand the difference between *global* and *local* modules. Since Express is for Nodejs we can now use npm to install express into our application. Express is the web application framework written for Nodejs. With npm installed you can now install Express. Now, in order to do some serious development with Nodejs you will also want to install NPM (which stands for Node Packaged Modules) which allows you to expand Node with, e.g. Thus you can simply issue “node” in the terminal. This install node and also adds it to your path. Once installed, you can simply install Nodejs with: To install Homebrew use this (in the terminal): In the many years I’ve used Homebrew I hardly ever had any issues with it. ![]() Homebrew pulls downs its updates from a global repository and keeps all packages up-to-date. In this guide I’m using Homebrew since this is seriously the best and easiest way to install software for the Mac. I’ve recently done a lot of work with Nodejs and thought I give a short installation guide on getting up and running on the Mac since there seems some confusion how to install it.
