1. Get an IDE
You’ll need to get one of the free IDEs in order to run Angular. See below :
For me, I recommend either IntelliJ IDEA or Visual Studio Code(VS Code) because they are free and feature rich.

5. Next Steps
If you have come this far, congrats!
We would now take a look at the file and folder structure of the Angular Application. Also, we have been working in the command line. In the next part, we would open this application using an IDE.
If you need to deploy an Angular application on a server running Apache, and are making use of routing for navigation, you can’t just upload the built application onto the server and be done with it. As soon as you navigate to another path, the Apache server will try to look for that resource on the server and most likely will give you an 404 Not Found error.
You need to rewrite all the URLs to the
index.html
so that the Angular application can take care of it. Your server needs to support mod_rewrite
for that. If that is the case, you can upload a file .htaccess
with the following content to your directory where the Angular application resides in.This will rewrite all requests to the
index.html
file and append any extra path to it. Unless, the request is for an existing file or directory on the server, then it will not rewrite it. This is necessary for the additional resources that will need to be loaded, such as CSS and JS files and images.Create Angular App
In order to get the necessary feedback when a resource is requested that does not exist, the third condition excludes to rewrite any request located inside the assets folder.
