How to define robots.txt for angular.js application?

@delpha 

To define the robots.txt file for an Angular.js application, follow these steps:

1. Create a new file called robots.txt in the root directory of your Angular.js application.
2. Open the robots.txt file in a text editor and specify the rules for search engine crawlers. For example, to allow all robots to crawl all parts of your application, use the following content:

1
2

User-agent: *
Disallow:

1. Save the robots.txt file and place it in the root directory of your Angular.js application.
2. Deploy your Angular.js application with the robots.txt file included. This will depend on how you are hosting your application. If you are using a web server, make sure to copy the file to the appropriate location on the server.
3. Test the robots.txt file to ensure it is correctly blocking or allowing access for search engine crawlers. You can use online tools, such as the "robots.txt Tester" in Google Search Console, to check if the rules are being enforced as intended.

Note: Keep in mind that Angular.js is a client-side JavaScript framework, so search engines might not be able to fully render and crawl your application by default. If you want to improve the visibility of your Angular.js application in search engine results, consider implementing server-side rendering or using a technology like Angular Universal.
