Let's go with two schemas <b>User</b> and <b>Bookmark</b> on different files ,where the relation is -
99+
- A User can have many bookmarks
100+
- Each bookmark has an userId field
101+
102+

```prisma
104+
generator client {
105+
provider = "prisma-client-js"
106+
}
107+
108+
datasource db {
109+
provider = "mongodb"
110+
url = env("PRISMA_DATABASE_URL")
111+
}
112+
```
113+
><b>user.prisma</b> [ root/prisma/subschemas/User/user.prisma ]
114+
```Prisma
115+
import { Bookmark } from "..\Bookmark\bookmark"
116+
model User {
117+
118+

119+
email String @unique
120+
121+
Bookmark Bookmark[]
122+
}
123+
//MongoDB model IDs in prisma -must have a @map("_id")

### Additional
171+
</summary>
172+
<p align="center">
173+
174+
- prisma schema files starting with header `//#exclude` will be excluded in final schema
175+
- Executing `npx prisma-multischema` will
176+
- <b>Automatically run</b> : `npx prisma generate`
177+
<br>So, You don't need to update `@prisma/client` manually, each time the schema updates
178+
- <b>Automatically run</b> : `npx prisma format`
179+
<br> because, Everyone likes clean code
180+
181+
- Add `npx prisma-multischema` command as a prefix to your <b>start</b> script in package.json.
182+
```json
183+
{
184+
"name": "my-app",
185+
"version": "1.0.0",
186+
"scripts": {
187+
"unify": "npx prisma-multischema",
188+
"start": "npm run unify && node index.js",
189+
...
190+
}
191+
}
192+
```
193+
<br>Now it will run & regenerate Main Schema everytime the project starts.
