📚 Documentation

For comprehensive API documentation and type definitions, see the API Reference section below.

📦 Importing

$3

`typescript
// Standard Prisma client
import { PrismaClient } from "@prisma/client";
import PrismaPaginate from "prisma-paginate-extension";

// Custom Prisma client paths also work
import { PrismaClient } from "./generated/client";
import PrismaPaginate from "prisma-paginate-extension";
`

$3

`javascript
const { PrismaClient } = require("@prisma/client");
const PrismaPaginate = require("prisma-paginate-extension").default;
`

> Note: The extension works seamlessly with any Prisma client instance, regardless of the import path. No additional configuration needed!

🔧 Usage

$3

`typescript
const prisma = new PrismaClient();
const xprisma = prisma.$extends(PrismaPaginate);

// Simple pagination with page and limit
xprisma.user
.paginate({ limit: 10, page: 1, select: { id: true, name: true } })
.then((result) => {
console.log(result);
});

// Pagination with filters
xprisma.post
.paginate({ where: { published: true } }, { limit: 10, page: 1 })
.then((result) => {
console.log(result);
});
`

$3

`typescript
// Assume database has 100 rows: [ { id: 1 }, { id: 2 }, ..., { id: 100 } ]
xprisma.user
.paginate(
{
where: {
active: true,
},
orderBy: {
createdAt: "desc",
},
},
{ page: 1, limit: 50 },
)
.then((result) => {
console.log(result.result); // Array of 50 users
console.log(result.totalPages); // Total number of pages
console.log(result.hasNextPage); // true if there's a next page
console.log(result.hasPrevPage); // true if there's a previous page
console.log(result.count); // Total count of records
});
`

$3

For complex queries using raw SQL, you can still leverage the pagination utilities:

`typescript
// Get the total count
const [{ count }] = await prisma.$queryRawUnsafe<[{ count: bigint }]>(
'SELECT COUNT(*) FROM "User";',
);

// Create pagination instance
const pagination = new Pagination(limit, page, Number(count));

// Execute paginated query
const data = await prisma.$queryRawUnsafe(
'SELECT name FROM "User" LIMIT $1 OFFSET $2;',
limit,
Pagination.offset(limit, page),
);
`

📋 API Reference

$3

`typescript
// Option 1: Combined findMany args and pagination
paginate(findManyPaginationArgs: PrismaFindManyArgs & PaginationArgs)

// Option 2: Separate findMany args and pagination
paginate(findManyArgs: PrismaFindManyArgs, paginationArgs: PaginationArgs)
`

$3

#### findManyArgs (Object)

Standard Prisma findMany arguments including:

- where - Filter conditions
- select - Fields to select
- include - Relations to include
- orderBy - Sorting options
- And all other Prisma query options

#### paginationArgs (Object)

Pagination configuration:

- page (Number) - Page number (starts from 1)
- limit (Number) - Number of items per page
- onCount? (Function) - Optional callback: (pagination: Pagination) => void

$3

The paginate() method returns a Promise with the following properties:

| Property | Type | Description |
| ------------------ | -------- | ---------------------------------------------- |
| result | Array | Array of paginated records |
| totalPages | Number | Total number of pages available |
| hasNextPage | Boolean | Whether a next page exists |
| hasPrevPage | Boolean | Whether a previous page exists |
| count | Number | Total count of all records matching the query |
| nextPage | Function | Returns Promise to fetch the next page |
| exceedCount | Boolean | Whether the query exceeded the maximum count |
| exceedTotalPages` | Boolean | Whether the requested page exceeds total pages |
