At the beginning of this year, I planned to use Node.js to rewrite the blog program based on the Express framework and say goodbye to ASP.NET. However, the VPS I am currently using is a Windows Server system and an IIS server. If both Express and IIS are allowed to listen to port 80, there will obviously be a conflict. Fortunately, there is an extension called iisnode that can host Node.js programs on IIS. Moreover, such hosting also means that you can use various functions in IIS (process management, GZip compression, logs, cache, permission control, domain name binding, etc.).
To use iisnode, you must install:
1.Node.js
2.URL Rewrite module of IIS
3.iisnode
After installation, follow the usual operations and create a site in the IIS manager, pointing to the directory of the Express program. The key is to add a web.config file:
in
This content can also be configured through the visual interface of IIS Manager. It probably means rewriting all requests to bin/www, and using the iisnode extension to run bin/www. However, after opening the site, this error message appeared:
Restart the site in IIS manager and access it again. It finally runs. It’s not easy! But it was still too early to be happy.
During the process of testing the function of the program, I found that the IP obtained was empty. In the Express framework, IP is obtained through req.ip, which in turn obtains the value from REMOTE_ADDR in the request header. Through a simple test code, it was found that the value of REMOTE_ADDR is also empty. Obviously, this header information was lost in the process from IIS to Node.js. After some Google, I found that iisnode does have
There is a configuration in Web.config (added before ) that can retain REMOTE_ADDR:

Copy code
However, after such adjustment, the obtained IP is still empty, which makes people wonder whether the assignment of req.ip failed. Looking at the source code of Express, we can find that req.ip is defined by define getter, so to overwrite it, you have to define it again:
Copy code
});
This problem is finally solved, but this is not a good method. It will be troublesome if Express sets req.ip to read-only in the future.
Continuing testing, another problem was discovered. Normally, the file upload function in the blog background will transfer files to the public/upload directory, but in fact, the public/upload folder is generated in the launch directory (the original bin directory). In fact, the reason is that the www file as the program entry is in the launch directory, so the launch directory becomes the execution directory of the application. My solution is to change the name of the launch directory back to bin, and create a launch.js in the root directory to call bin/www:

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
