Batch Create README.md Files in Every Directory Using Node.js

Have you ever found yourself needing to create a README.md file for each folder in a directory? If you're working on a Node.js project with multiple subdirectories, this task can quickly become tedious. However, with a little bit of coding, you can automate this process! In this post, we’ll walk through how to batch create README.md files in every folder using Node.js.

The Problem

The challenge arises when you have several directories within your current directory, and you want to create a README.md file in each one. Initially, you might try something like this:

While this code is a good start, it doesn’t achieve the intended result. Here are a few issues with this approach:

The writeFile method doesn’t provide the full path, so it will not create the files in the desired directories.

The method does not filter for directories, so it will attempt to create a README.md in unintended locations.

The Solution: Improving the Code

Understanding fs.writeFile Parameters

To successfully create files, we need to understand how to use the fs.writeFile method correctly. The correct syntax is:

Where:

file is the path of the file you want to create or write to.

data is the content you want to write.

options are optional parameters (like encoding), and callback is used to handle any errors.

Revised Code Implementation

Let’s rework the initial code to ensure that we create a README.md file in every folder. Here's an improved version:

Code Explanation

Importing Modules: We import the necessary fs (File System) and path modules to interact with files and directories.

Reading the Directory: We use fs.readdirSync to synchronously read the contents of the current directory.

Filtering for Directories: The code filters out files to retain only the directories using fs.lstatSync to check if each item is a directory.

Creating the README.md Files: For each folder, we generate a full path for the README.md file and write an empty file. If successful, we log a confirmation message.

Conclusion

By automating the file creation process with Node.js, you save valuable time and ensure consistency across your project directories. With this improved code, you can easily create a README.md file in every folder within your current directory. Give it a try, and let us know how it works out for you!

Now you can focus on more complex tasks instead of manual file creation – happy coding!
