Nodejs routing error when loading static web page

In the process of developing web applications using Node.js, it is often necessary to use the routing mechanism to manage different pages of the website. When routing loads static web pages, sometimes you will encounter some errors. This article will introduce some reasons that may cause routing errors when loading static web pages, and provide some solutions.

1. Path error
   When writing routing code, if the path is wrong, the static web page will not be loaded correctly. Common causes of this error include the following:

• Path writing error: The writing of the path in the routing code must be consistent with the actual path.
• Missing static web page file: The routing code calls the web page file, but the web page file does not exist, or the file name is incorrect.
• The path contains spaces: Containing spaces in the path may be parsed as " ", resulting in a path error.

Solution:
Check whether the path is correct, ensure that the web page file exists, and track the error message to determine the specific path error type.

2. Configuration Error
   In Node.js applications, if the routing configuration is incorrect, the static web page file cannot be called correctly.

Solution:
Configure application routing correctly and ensure that the routing code is correct.

3. The route and the static file have the same name
   When the route and the static file have the same name, the static file will not be loaded correctly because the route has a higher priority. This problem is common in the routing framework of Node.js.

Solution:
Modify the naming of routes or static files to ensure that the same name does not occur.

4. Lack of static file middleware
   When loading static files using Node.js, you need to use middleware to load them correctly. If the middleware is not configured correctly or installed, static files cannot be loaded.

Solution:
Use Node.js middleware such as express.static, or other suitable middleware to process static files.

To sum up, the reasons for routing errors when loading static web pages may include path errors, configuration errors, same name issues, missing middleware, etc. To solve these problems, you need to carefully check the code and configuration to ensure that the paths and contents are correct, and install the necessary middleware. This will help ensure the stability and good user experience of Node.js applications.
