At Koj, we use this package to automatically generate [`@koj/types`](https://www.npmjs.com/package/@koj/types) from our Prisma schema.
## ⭐️ Features
The `readAndGenerateClassValidator` method reads your generated Prisma client (after running `npx prisma generate`) and automatically generates a class-validator schema.
First, install from npm:
```bash
npm install --save-dev prisma-class-validator
```
Usage with TypeScript/Node.js:
```ts
import { readAndGenerateClassValidator } from "prisma-class-validator";
import { writeFile } from "fs/promises";
(async () => {
const schema = await readAndGenerateClassValidator();
await writeFile("validator.ts", schema);
})();
```
Usage with JavaScript/Node.js:
```js
const { readAndGenerateClassValidator } = require("prisma-class-validator");
const { writeFile } = require("fs/promises");
(async () => {
const schema = await readAndGenerateClassValidator();
await writeFile("validator.ts", schema);
})();
```
## 💻 Example
The `generateClassValidatorFromPrismaClient` method is used to take a string consisting of generated Prisma schema and converting it to class-validator. In this case, you are expected to read the generated Prisma schema `index.d.ts` file and supply that as the input.
Example input
```ts
generateClassValidatorFromPrismaClient(`
/**
* Client
**/
import * as runtime from '@prisma/client/runtime';
/**
* Model Lead
*/
export type Lead = {
browser: string | null
city: string | null
countryCode: string | null
createdAt: Date
email: string
id: number
name: string
operatingSystem: string | null
region: string | null
responses: Prisma.JsonValue | null
timezone: string | null
updatedAt: Date
}
/**
* Model User
*/
export type User = {
active: boolean
attributes: Prisma.JsonValue | null
checkLocationOnLogin: boolean
countryCode: string
createdAt: Date
gender: Gender
}
/**
* Enums
*/
// Based on
// https://github.com/microsoft/TypeScript/issues/3192#issuecomment-261720275
export const Gender: {
FEMALE: 'FEMALE',
MALE: 'MALE',
NONBINARY: 'NONBINARY',
UNKNOWN: 'UNKNOWN'
};
export type Gender = (typeof Gender)[keyof typeof Gender]
`);
```
Resulting output
```ts
`/**
* DO NOT EDIT THIS FILE MANUALLY
* ==============================
*
