The article showcases a command-line tool called "pm_ts" that generates TypeScript interfaces based on Postman collection JSON files. The tool, built on top of Node.js, extracts information from the Postman collection JSON, including examples response output, URL request query parameters, and URL request query body.

Developers can use the tool by exporting their Postman collection and running the script with the appropriate command-line arguments. The script supports various flags, with the "-i" and "-o" flags being the most stable. After successful execution, the folder structure will change, and developers will see the generated TypeScript interfaces.

The author notes that the project is still in the beta stage and may occasionally return files with "undefined" values. They encourage users to contribute to the project and report any issues they encounter.

This tool is beneficial for developers working with TypeScript and Postman, as it automates the process of generating TypeScript interfaces from Postman collections, saving time and effort. It simplifies the integration between API testing and TypeScript development, ensuring type safety and consistency in the codebase.
