nodejs recursively read directory

To recursively read a directory in Node.js, you can use the built-in fs module. Here are the steps:

  1. Import the fs module by including the following line at the beginning of your code:
const fs = require('fs');

  1. Create a function that takes the path of the directory as a parameter. This function will be responsible for reading the contents of the directory and its subdirectories recursively.

  2. Inside the function, use the fs.readdirSync() method to retrieve an array of the directory's contents. This method is synchronous, meaning it will block the execution until the contents are retrieved.

  3. Iterate through the array of directory contents using a loop or a forEach function. For each item in the array, check if it is a file or a directory.

  4. If the item is a file, you can perform the desired operation on it.

  5. If the item is a directory, recursively call the same function with the path of the subdirectory. This will repeat the process for the subdirectory's contents.

  6. Make sure to handle any errors that may occur during the reading process using try-catch blocks or error handling functions.

  7. Optionally, you can include additional logic to filter or exclude specific files or directories based on certain criteria.

By following these steps, you can recursively read a directory in Node.js and perform operations on its contents.
