VINNER TECH June 19, 2023

ASP.NET Core - wwwroot Folder



1. Overview The wwwroot folder is a special directory in an ASP.NET Core application that is used to store static files, such as HTML, CSS, JavaScript, images, and other assets. These files can be directly accessed by clients, without any processing by the server. This documentation provides an overview of the wwwroot folder and demonstrates how to use it in an ASP.NET Core application.

2. Location The wwwroot folder is located at the root of an ASP.NET Core application's project structure. By default, it is named wwwroot, but this can be changed by modifying the application's configuration.

3. Purpose The primary purpose of the wwwroot folder is to provide a location for serving static files to clients. These files are typically accessible using a URL path that corresponds to their location within the wwwroot folder.

4. Usage To use the wwwroot folder in an ASP.NET Core application, follow these steps:

4.1. File Structure Create a folder named wwwroot at the root of your ASP.NET Core application's project structure. The folder should have the following structure:

markdown
- wwwroot
  - css
  - js
  - images
  - ...

4.2. File Placement Place your static files, such as HTML, CSS, JavaScript, images, etc., in the appropriate subdirectories within the wwwroot folder. For example, CSS files can be placed in the wwwroot/css directory, JavaScript files in the wwwroot/js directory, and images in the wwwroot/images directory.

4.3. Serving Files The files within the wwwroot folder can be accessed directly by clients using their corresponding URL paths. For instance, if you have a file named styles.css inside the wwwroot/css directory, it can be accessed using the URL path https://example.com/css/styles.css.

5. Example Here's an example of using the wwwroot folder in an ASP.NET Core application:

5.1. Project Structure

markdown
- MyAspNetCoreApp
  - Controllers
  - Models
  - ...
  - wwwroot
    - css
      - styles.css
    - js
      - script.js
    - images
      - logo.png
  - ...

5.2. File Usage Assuming the above project structure, the CSS file styles.css can be referenced in an HTML file as follows:

html
<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="/css/styles.css">
</head>
<body>
    <!-- Content of the web page -->
</body>
</html>

Similarly, the JavaScript file script.js can be included in an HTML file like this:

html
<!DOCTYPE html>
<html>
<head>
    <script src="/js/script.js"></script>
</head>
<body>
    <!-- Content of the web page -->
</body>
</html>

And the image logo.png can be used in an HTML file using the <img> tag:

html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
    <img src="/images/logo.png" alt="Logo">
    <!-- Content of the web page -->
</body>
</html>

6. Conclusion The wwwroot folder is a crucial component of an ASP.NET Core application, providing a convenient location for serving static files. By following the outlined steps and organizing your files correctly, you can easily incorporate CSS, JavaScript, images, and other assets into your web application.
