Show HN: File-Fabric – Generate Files (docs, media, archives) for Testing

1 freakynit 0 8/20/2025, 8:01:10 AM

https://github.com/freakynit/file-fabric

I just released File-Fabric, a tiny TypeScript toolkit to generate various files for demos, CI fixtures, prototypes, and seeding workflows.

It can produce documents (PDF, DOCX, TXT, JSON), spreadsheets/slides (XLSX, CSV, PPTX), media (JPG/PNG, WAV/MP3, MP4), and archives (ZIP, optional RAR). Everything has sensible defaults, with options to control size, duration, text, etc.

Supports both direct API usage and YAML-driven batch generation. Great for quickly spinning up sample data without hunting for random files.

Repo: https://github.com/freakynit/file-fabric

Would love feedback from folks who’ve struggled with needing realistic files for tests or demos!
