prisma-generator-js-enums

Prisma generator that creates JavaScript or TypeScript enum objects from your Prisma schema enums.

Install

npm install prisma-generator-js-enums

Usage

Add the generator to your schema.prisma:

generator jsEnums {
  provider = "prisma-generator-js-enums"
  output   = "./generated/enums"
}

Then run:

npx prisma generate

Schema

enum Role {
  USER
  ADMIN
  MODERATOR
}

enum Status {
  ACTIVE
  INACTIVE
}

JS output (default)

const Role = Object.freeze({
  USER: "USER",
  ADMIN: "ADMIN",
  MODERATOR: "MODERATOR",
});

const Status = Object.freeze({
  ACTIVE: "ACTIVE",
  INACTIVE: "INACTIVE",
});

module.exports = { Role, Status };

TypeScript output

Set outputType = "ts" to generate TypeScript with as const objects and union types:

generator jsEnums {
  provider   = "prisma-generator-js-enums"
  output     = "./generated/enums"
  outputType = "ts"
}

export const Role = {
  USER: "USER",
  ADMIN: "ADMIN",
  MODERATOR: "MODERATOR",
} as const;

export type Role = (typeof Role)[keyof typeof Role];
// "USER" | "ADMIN" | "MODERATOR"

export const Status = {
  ACTIVE: "ACTIVE",
  INACTIVE: "INACTIVE",
} as const;

export type Status = (typeof Status)[keyof typeof Status];
// "ACTIVE" | "INACTIVE"
