Prisma Pagination Extension

Introduction

Prisma Client extension for pagination.

Features

• Page number pagination
• Cursor-based pagination
• Fully tested

Installation

pnpm install @zhangwj0520/prisma-extension-pagination

Install extension to all models

import { PrismaClient } from "@prisma/client";
import { pagination } from "@zhangwj0520/prisma-extension-pagination";

const prisma = new PrismaClient().$extends(pagination());

Install extension on some models

import { PrismaClient } from "@prisma/client";
import { paginate } from "@zhangwj0520/prisma-extension-pagination";

const prisma = new PrismaClient().$extends({
  model: {
    user: {
      paginate,
    },
  },
});

Change default settings

import { PrismaClient } from "@prisma/client";
import { pagination } from "@zhangwj0520/prisma-extension-pagination";

const prisma = new PrismaClient().$extends(
  pagination({
    pageSize: 10,
  })
);

When using the extension on some models, you need to use createPaginator function to set the default values:

import { PrismaClient } from "@prisma/client";
import { createPaginator } from "prisma-extension-pagination";

const paginate = createPaginator({
  pageSize: 10,
});

// You can create many paginators with different settings.
// They can be reused for different models.

const prisma = new PrismaClient().$extends({
  model: {
    user: {
      paginate,
    },
    post: {
      paginate,
    },
  },
});

Usage

Page number pagination

Page number pagination uses pageSize to select a limited range and current to load a specific current of results.

• Load first current
• Load specific current

Load first current

const res = await prisma.user
  .paginate({
    select: {
      id: true,
    }
  })
  .withPages({
    pageSize: 10,
  });
{
  list: users,
  total:100,
  pagination: {
    pageSize: 10
    current: 1;
  }
}  

Load specific current

const res = await prisma.user
  .paginate()
  .withPages({
    pageSize: 10,
    current: 2,
  });

// res contains the following
{
  list: users,
  total:100,
  pagination: {
    pageSize: 10
    current: 2;
  }
}  

Load all results

Sometimes it's useful to return all results, if you need to do that, you can pass pageSize: null.
