⚠️ 改进

• 改进计算结果是标准json,方便服务器组件跟客户端组件的交互

Documentation and usage

For more details and type definitions see:

http://sandrewtx08.github.io/prisma-paginate/

Importing

// ESM
import { PrismaClient } from "@prisma/client";
import {extension} from "@liuhuapiaoyuan/prisma-paginate";

// Commonjs
const { PrismaClient } = require("@prisma/client");
const { extension } = require("prisma-paginate");

Applying extension

const prisma = new PrismaClient();
const xprisma = prisma.$extends(extension);

xprisma.model2
	.paginate({ limit: 10, page: 1, select: { id: true } })
	.then((result) => {
		console.log(result);
	});

xprisma.table1
	.paginate({ where: { id: 5 } }, { limit: 10, page: 1 })
	.then((result) => {
		console.log(result);
	});

Paginating 100 rows

// on database = [ { id: 1 }, { id: 2 }, {...}, { id: 100 } ]
xprisma.model1
	.paginate(
		{
			where: {
				// query stuff...
			},
		},
		{ page: 1, limit: 50 },
	)
	.then((result) => {
		console.log(result.result); // [ {...}, { id: 48 }, { id: 49 }, { id: 50 } ]
	});

Paginating SQL queries

const [{ count }] = await prisma.$queryRawUnsafe<[{ count: bigint }]>(
	'SELECT COUNT(*) FROM "Model3";',
);

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

const data = await prisma.$queryRawUnsafe<unknown[]>(
	'SELECT name FROM "Model3" LIMIT $1 OFFSET $2;',
	limit,
	Pagination.offset(limit, page),
);

Parameters

• findManyArgs {Object}
• paginationArgs {Pagination&onCount?(pagination) => void}

• findManyPaginationArgs {Object&Pagination}

Return

• result {Array}
• totalPages {Number}
• hasNextPage {Boolean}
• hasPrevPage {Boolean}
• count {Number}
• nextPage {() => Promise}
• exceedCount {Boolean}
• exceedTotalPages {Boolean}
