Automating My MDX Blog Workflow with a Simple Node.js Script

I maintain a private MDX blog repo that I sometimes push updates from. My portfolio website displays these posts as a blog page.

But over time, a few small annoyances piled up:

Every time I write a new post, I have to manually create the .mdx file with a proper filename like sorting-p5-visualization.mdx.
I need to check the last post’s ID to assign the next one correctly.
I have to manually add frontmatter (ID, date, title, tags) every time.

It wasn’t a huge problem, but it felt repetitive and slow.

So, I decided to automate it.

The Automation Script

With a simple Node.js script, I can now:

Generate a new post boilerplate with just one command.
Provide a title (required) and optional tags.
Automatically update the next ID and current date.
Check the last post info, including file path.
Search for any post by ID.

commands:

# Create a new post with tags
pnpm new "Print all zero sum subarray" --tag "algorithm,arrays,dsa,python,hashmap,interview"

# Check last post
pnpm last

# Get info about a post by ID
pnpm post --id 19

The script takes care of creating the .mdx file, adding frontmatter, and maintaining IDs. No more copying boilerplate or double-checking filenames.

Why This Feels “Pretty Cool”

One-liner creation: I can generate a full post skeleton in seconds.
Safe ID management: Never worry about duplicate IDs.
Optional tags: Helps keep posts organized without extra typing.
Quick info retrieval: Last post or specific ID info is just a command away.

For a private or small MDX-based blog, this is a simple but huge productivity boost.
