If you are involved in web development, you will often come across the term “localhost”. But what exactly does “localhost” mean and how does it work?
What is “localhost”?
“Localhost” is a term used to refer to the computer you are currently working on. In the context of web development and network technology, “localhost” stands for your own machine and not for a remote server on the Internet.
How does it work?
- Virtual server: If you enter “localhost” in your web browser, you are accessing a web server that runs on your own computer. This web server can be part of a development environment such as XAMPP, MAMP or WAMP, which allows you to create and test websites and web applications locally.
- IP address: “Localhost” uses the IP address 127.0.0.1, which always points to your own computer. This IP address is, so to speak, a special address that always points to your own machine, regardless of how your computer is connected to the Internet.
- Test environment: When working with “localhost”, you can develop and test websites and web applications without having to put them online. This is particularly useful for safely testing changes or new functions before you publish them on a public server.
Why is “localhost” useful?
- Development and testing: By using “localhost”, you can develop and test your projects in a controlled environment. You have full access to the web server and database without having to worry about other users accessing your development work.
- Speed: Accessing a local server is usually faster than accessing a remote server. This speeds up the development process and allows you to see changes quickly.
- Security: Since “localhost” is only available on your own computer, you can work securely without your data or development work being accidentally published.
How do I access it?
To access “localhost”, simply open a web browser and enter http://localhost or http://127.0.0.1 in the address bar. If you have a local development environment like XAMPP installed, you can access your project files that are stored in the “htdocs” folder of your XAMPP installation.
For example, entering http://localhost/meinprojekt in your browser will access the files in the “myproject” folder in the “htdocs” directory.
Conclusion
“Localhost” is a fundamental concept in web development that allows you to develop and test websites and web applications locally on your own computer. It’s like a virtual server on your own computer that helps you create your projects securely, quickly and efficiently. By using “localhost”, you can ensure that your development work takes place under controlled conditions before you go live.
