Here, we are telling Angular CLI to generate a new project called “hello-world” and store it in a folder with the same name. We provide a command (in this case new) to instruct Angular CLI on what we want it to do for us. So with Angular CLI in place, now we can create a new Angular project using the following command: ng new hello-worldĪs you can see, we can access Angular CLI using ng. If you’re on Mac, you need to put sudo at the beginning of this command to execute it as an administrator otherwise, you’ll get permission errors. If you don’t put -g here, Angular CLI will be installed only in the current folder, and it’s not going to be accessible anywhere else.

So, once again in the Terminal, run the following command to install Angular CLI: npm install -g -g flag stands for global.

It is also used for generating some boilerplate code during development (such as components, services, etc) as well as building an application for deployment. That is a command-line tool we use to create a new Angular project. In this tutorial, we’re going to use NPM to install Angular CLI. Node comes with a tool called Node Package Manager or NPM, which is used for installing third-party libraries. So, if you haven’t installed Node, head over to, and install the latest stable version. Now, let’s get dive into some code and get our hands dirty! The first thing you need to install is the latest version of Node. My suggestion to you is to learn the fundamentals of each of these frameworks and choose the one that works best for each project depending on its requirements. Each of these frameworks have strengths and weaknesses and there is no one shiny framework that makes every developer in the world happy.
These days there is a lot of debate between Angular vs React vs Vue.js. Whether Angular is better than React or Vue.js depends on how you define “better”. Sure, there is a learning curve involved, but once you master Angular, you’ll be able to build client applications faster and easier. But using a framework like Angular, makes your life far easier. But as your application grows, structuring your code in a clean and maintainable and more importantly, testable way, becomes harder and harder. In fact, a lot of web applications out there are built this way. There is nothing inherently wrong with using vanilla JavaScript/jQuery. Why do I need a framework like Angular?Ī common question a lot of beginners ask me is: “Why do we need Angular in the first place? What’s wrong with the plain old vanilla JavaScript and jQuery?”. And that’s the job of the TypeScript compiler. This process is called transpilation which is the combination of translate and compile. So, when building Angular applications, we need to have our TypeScript code converted into JavaScript code that browsers can understand. But many prefer TypeScript because it has additional features that we don’t have in the current version of JavaScript that most browsers understand. That means any valid JavaScript code is valid TypeScript code.
I will give you the basics in order to complete this tutorial. If you have never worked with TypeScript before, don’t worry. What is Angular?Īngular is a framework for building client applications in HTML, CSS, and either JavaScript or a language like TypeScript that can be compiled (more accurately, transpiled) to JavaScript.

If you’ve used any previous versions of Angular, feel free to skip this section and jump to “Getting the tools”. Let’s start with a few beginner’s questions.
