JsonGPT

JsonGPT is a simple library for generating JSON from a template.

You can use it as a cli tool to generate once or run a local server to generate on demand.

Why?

Well, starting from "why spend 10 minutes to do something while you can spend a couple of hours to automate it?". I was working on a project and starting with the frontend and wanted to test and generate JSON. So I used GPT to describe to it the shape I wanted and it generates it for me.

Also an obligatory why not?

Installation

For now, you can just clone the repo and build it yourself.

Looking into publishing binaries.
