I made Factory-js inspired by factory-bot (https://github.com/thoughtbot/factory_bot), supports Prisma and Drizzle ORM and more. TypeScript is now widely used in both backend and frontend, but there is no de facto standard factory library. I'm developing a web application using Prisma, trpc, and nextjs, but I was struggling with how to write more beautiful and readable back-end tests. That's why I made factory-js.
