Express Production Setup - 3 | CORS

 Express Production Setup - 3 | CORS  To enable Cross-Origin Resource Sharing (CORS) in an Express.js application, you can use the cors middleware package. This middleware allows you to control which domains can access your API, what methods are allowed, and what headers can be sent in requests. index.js     const express = require (' express ');     const cors = require (' cors ');     const app = express ();     // CORS options to allow only POST requests     const corsOptions = {         origin: ' http://example.com ', // Replace with your client's origin         methods: [' POST ', " GET ", " PUT ", " PATCH ", " DELETE "],         credentials: true // allow cookies     };     // Apply CORS middleware with the above options     app . use ( cors ( corsOptions ));     // Example route     app . post (' /a...

Ensuring File Creation in the Current Directory when Converting Python (.py) Script to Executable (.exe). When you create a file in Python within the current directory, everything works seamlessly. However, if you decide to convert your Python script into a standalone executable (.exe) using tools like PyInstaller, you might encounter a situation where the file is created in a temporary folder, and upon code execution completion, it mysteriously disappears. To overcome this challenge and ensure that your file appears in the current directory, consider using the following code snippet: Explanation: In the above code, we use sys.frozen to check if the script is running in a frozen (compiled into an executable) environment. This is particularly relevant when the script is converted to a standalone executable using tools like PyInstaller. When the script is running as a .py file, myPath is set to the absolute path of the script using os.path.abspath(__file__). When the script is running as...
