In this post, you would learn about how to quickly get started with Angular 7 hello world app. Here are the steps to build the Angular App. Actually, the steps could be used to build an Angular app with any version of Angular such as Angular 6 or Angular 5.
npm install -g @angular/cli
In case, you have earlier versions such as Angular 6.* installed on your system, execute the following command to migrate to Angular 7 version.
ng update @angular/cli @angular/core
ng new smart-resumes
cd smart-resumes ng serve --open
The above would make the app accessible at the port, 4200. In case, the port is already in use, one could use the following command:
ng serve --open --port 4300
Go to a browser window and access the app at the URL such as http://localhost:4300.
In this post, you learned about steps which could be taken to create your first Hello World App using Angular 7. The important point to note is that one would need to have NodeJS and NPM (Node Package Manager) installed/updated to start working with Angular Apps. It is the Angular-CLI which makes it easy to create an Angular project and create boilerplate code for modules, components etc.
