[Site Web personnel] Comment intégrer la base de données Notion dans Next

Untuk menyepadukan pangkalan data Notion ke dalam projek Next.js, anda boleh menggunakan Notion sebagai sistem pengurusan kandungan (CMS) dan memaparkan kandungannya di tapak web anda. Di bawah ialah panduan langkah demi langkah yang mudah untuk membantu anda menyepadukan pangkalan data Notion ke dalam Next.js.

Persediaan Asas

Dapatkan Kunci API Notion dan ID Pangkalan Data

1. Dapatkan Kunci API Notion: Pergi ke Portal Pembangun Notion dan buat penyepaduan baharu. Setelah dibuat, anda akan menerima kunci API.
2. Dapatkan ID Pangkalan Data: Navigasi ke pangkalan data Notion yang anda mahu integrasikan, dan salin URL halaman pangkalan data. ID pangkalan data ialah rentetan aksara antara https://www.notion.so/ dan ?v= dalam URL.

Menggunakan SDK Rasmi

Langkah 1: Pasang Ketergantungan

Pertama sekali, anda perlu memasang SDK rasmi Notion, @notionhq/client, untuk berkomunikasi dengan API Notion. Anda boleh memasangnya menggunakan npm atau yarn:

npm install @notionhq/client
# or
yarn add @notionhq/client

Langkah 2: Sediakan Klien Notion

Buat fail lib/notion.js dalam direktori akar projek Next.js anda dan konfigurasikan klien Notion seperti berikut:

// lib/notion.js
import { Client } from '@notionhq/client';

const notion = new Client({
  auth: process.env.NOTION_API_KEY,
});

export const getDatabase = async (databaseId) => {
  const response = await notion.databases.query({ database_id: databaseId });
  return response.results;
};

Pastikan menyimpan kunci API Notion anda dalam pembolehubah persekitaran NOTION_API_KEY.（.env.local）

NOTION_API_KEY=your_secret_api_key

Langkah 3: Ambil Kandungan Pangkalan Data

Dalam halaman Next.js anda, anda boleh menggunakan getStaticProps atau getServerSideProps untuk mengambil kandungan daripada pangkalan data Notion.

// pages/index.js
import { getDatabase } from '../lib/notion';

export const getStaticProps = async () => {
  const databaseId = process.env.NOTION_DATABASE_ID;
  const posts = await getDatabase(databaseId);

  return {
    props: {
      posts,
    },
    revalidate: 1, // ISR (Incremental Static Regeneration)
  };
};

export default function Home({ posts }) {
  return (
    <div>
      <h1>My Notion Blog</h1>
      <ul>
        {posts.map((post) => (
          <li key={post.id}>
            {post.properties.Name.title[0].plain_text}
          </li>
        ))}
      </ul>
    </div>
  );
}

Pastikan anda mempunyai ID pangkalan data Notion anda disimpan dalam NOTION_DATABASE_ID sebagai pembolehubah persekitaran.

NOTION_DATABASE_ID=your_database_id

Langkah 4: Penerapan dan Pengesahan

Akhir sekali, gunakan projek Next.js anda ke Vercel atau platform lain dan sahkan bahawa anda berjaya mengambil dan memaparkan data daripada pangkalan data Notion.

Petua Tambahan

Anda boleh memaparkan sifat halaman Notion yang berbeza (seperti Nama, Teg, Tarikh, dll.) pada halaman anda.
Pertimbangkan untuk menggunakan getServerSideProps untuk mengambil data pada setiap permintaan atau gunakan getStaticProps dengan ISR (Incremental Static Regeneration) untuk mengoptimumkan prestasi.

Dengan mengikut langkah ini, anda boleh berjaya menyepadukan pangkalan data Notion ke dalam projek Next.js anda dan menggunakannya untuk mengurus serta memaparkan kandungan.

Menggunakan Notion API dengan URL Berbalut

Akhir sekali, saya akhirnya menggunakan kaedah ini untuk kemudahan apabila menyepadukan dengan komponen react-notion-x.

Pastikan anda menambah ID Pangkalan Data Notion dan Kunci API Notion anda pada fail .env.local:

NOTION_DATABASE_ID=your_database_id
NOTION_API_KEY=your_secret_api_key

Langkah 1: Pasang kebergantungan yang diperlukan

Mula-mula, pasang kebergantungan yang diperlukan seperti notion-types, notion-utils dan perlu mengendalikan permintaan kepada Notion API.

npm install notion-types notion-utils got p-map

Langkah 2: Buat fail untuk merangkum interaksi Notion API

Dalam projek Next.js anda, buat fail, contohnya, lib/NotionAPI.ts, yang akan merangkum interaksi dengan API Notion. Fail ini akan mengandungi kaedah untuk memanggil titik akhir Notion API untuk mengambil data daripada halaman dan koleksi.

// lib/NotionAPI.ts
import * as notion from "notion-types";
import got, { OptionsOfJSONResponseBody } from "got";
import {
  getBlockCollectionId,
  getPageContentBlockIds,
  parsePageId,
  uuidToId,
} from "notion-utils";
import pMap from "p-map";

// 定义权限记录接口
export interface SignedUrlRequest {
  permissionRecord: PermissionRecord;
  url: string;
}

export interface PermissionRecord {
  table: string;
  id: notion.ID;
}

export interface SignedUrlResponse {
  signedUrls: string[];
}

// 定义NotionAPI类
export class NotionAPI {
  private readonly _apiBaseUrl: string;
  private readonly _authToken?: string;
  private readonly _activeUser?: string;
  private readonly _userTimeZone: string;

  constructor({
    apiBaseUrl = "<https://www.notion.so/api/v3>",
    authToken,
    activeUser,
    userTimeZone = "America/New_York",
  }: {
    apiBaseUrl?: string;
    authToken?: string;
    userLocale?: string;
    userTimeZone?: string;
    activeUser?: string;
  } = {}) {
    this._apiBaseUrl = apiBaseUrl;
    this._authToken = authToken;
    this._activeUser = activeUser;
    this._userTimeZone = userTimeZone;
  }

        })),
      },
      gotOptions,

  }
}

Langkah 3: Gunakan Encapsulated API dalam Next.js Pages

Untuk mengambil kandungan pangkalan data Notion dalam halaman Next.js anda, anda boleh menggunakan kelas NotionAPI terkapsul dan menghantar data yang diambil kepada komponen reaksi-notion-x untuk pemaparan.

// pages/[pageId].tsx
import { GetServerSideProps } from 'next';
import { NotionAPI } from '../lib/NotionAPI';
import { NotionRenderer } from 'react-notion-x';
import 'react-notion-x/src/styles.css';

export const getServerSideProps: GetServerSideProps = async (context) => {
  const { pageId } = context.params;
  const notion = new NotionAPI();
  const recordMap = await notion.getPage(pageId as string);

  return {
    props: {
      recordMap,
    },
  };
};

const NotionPage = ({ recordMap }) => {
  return <NotionRenderer recordMap={recordMap} fullPage={true} darkMode={false} />;
};

export default NotionPage;

Langkah 4: Konfigurasikan Penghalaan dalam Next.js

Untuk memastikan bahawa fail [pageId].tsx boleh memaparkan halaman Notion yang berbeza secara dinamik, anda perlu menyediakan penghalaan dinamik dalam Next.js. Ini akan membolehkan anda memadankan parameter pageId dan mengambil kandungan halaman Notion yang sepadan.

Berikut ialah cara anda boleh mengkonfigurasi laluan dinamik:

1. Buat Fail Laluan Dinamik dalam direktori halaman:

Dalam direktori halaman anda, buat fail baharu bernama [pageId].tsx:

pages/[pageId].tsx

1. Laksanakan Perenderan Halaman Dinamik:

Dalam fail [pageId].tsx, ambil kandungan Notion berdasarkan pageId daripada URL dan jadikannya secara dinamik.

Contoh kod:

import { GetStaticProps, GetStaticPaths } from 'next';
import { NotionRenderer } from 'react-notion-x';
import { getNotionPageData } from '../lib/NotionAPI';
import 'react-notion-x/src/styles.css';

export default function NotionPage({ pageData }) {
  return (
    <div>
      <NotionRenderer recordMap={pageData} fullPage={true} darkMode={false} />
    </div>
  );
}

export const getStaticProps: GetStaticProps = async ({ params }) => {
  const { pageId } = params!;
  const pageData = await getNotionPageData(pageId as string);

  return {
    props: {
      pageData,
    },
    revalidate: 10, // Revalidate content every 10 seconds (ISR)
  };
};

export const getStaticPaths: GetStaticPaths = async () => {
  return {
    paths: [], // We’ll use fallback to handle dynamic routes
    fallback: 'blocking', // Generate pages on the fly if not pre-rendered
  };
};

1. Explanation:
2. getStaticPaths: Since your content is dynamic, we return an empty array for paths and set fallback: 'blocking' to generate pages on demand.
3. getStaticProps: Fetches the Notion page content based on the pageId passed in the URL.

Summary

By following the steps above, you can now encapsulate Notion API requests and render Notion pages dynamically in your Next.js project using react-notion-x. This setup allows you to efficiently integrate Notion as a CMS while ensuring scalability and maintainability in your Next.js application.
