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...
