Installation

Open a Terminal in the project root and run:

npm install @sergeymyssak/nextjs-sitemap

or

yarn add @sergeymyssak/nextjs-sitemap

Quick start

Example src folder:

└── src
    └── pages
        ├── projects
        │   ├── computers
        │   │   ├── laptop.js
        │   │   └── pc.js
        │   └── phones
        │       ├── android.js
        │       └── ios.js
        ├── admin
        │   ├── account.js
        │   └── cms.js
        └── index.js

All static routes from pages folder will be automatically added to the sitemap.

// import { configureSitemap } from '@sergeymyssak/nextjs-sitemap';
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');

const Sitemap = configureSitemap({
  domains: [{ domain: 'example.com', defaultLocale: 'en', http: true }],
  exclude: ['/admin/*'],
  excludeIndex: true,
  pagesConfig: {
    '/projects/*': {
      priority: '0.5',
      changefreq: 'daily',
    },
  },
  trailingSlash: true,
  targetDirectory: __dirname + '/public',
  pagesDirectory: __dirname + '/src/pages',
});

Sitemap.generateSitemap();

With exportPathMap

If you specify nextConfigPath prop, then all values indicated in the exportPathMap will be automatically added (pages folder will be ignored).

// import { configureSitemap } from '@sergeymyssak/nextjs-sitemap';
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');

const Sitemap = configureSitemap({
  exclude: ['/admin'],
  excludeIndex: true,
  pagesConfig: {
    '/p/*': {
      priority: '0.5',
      changefreq: 'daily',
    },
  },
  nextConfigPath: __dirname + '/next.config.js',
  targetDirectory: __dirname + '/public',
  pagesDirectory: __dirname + '/src/pages',
});

Sitemap.generateSitemap();

With dynamic routes

For dynamic routes, you have to declare them with the include property.

Example src folder:

└── src
    └── pages
        ├── project
        │   └── [id].js
        └── index.js

// import { configureSitemap } from '@sergeymyssak/nextjs-sitemap';
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');

async function fetchDynamicPaths() {
  return ['house', 'flower', 'table'];
}

async function getDynamicPaths() {
  const paths = await fetchDynamicPaths();

  return paths.map((item) => `/project/${item}`);
}

getDynamicPaths().then((paths) => {
  const Sitemap = configureSitemap({
    domains: [{ domain: 'example.com', defaultLocale: 'en' }],
    include: paths,
    exclude: ['/project/*'],
    excludeIndex: true,
    pagesConfig: {
      '/project/*': {
        priority: '0.5',
        changefreq: 'daily',
      },
    },
    trailingSlash: true,
    targetDirectory: __dirname + '/public',
    pagesDirectory: __dirname + '/src/pages',
  });

  Sitemap.generateSitemap();
});

With localization

If you have localization, you can use locales in domains prop.

// import { configureSitemap } from '@sergeymyssak/nextjs-sitemap';
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');

const Sitemap = configureSitemap({
  domains: [{ domain: 'example.com', locales: ['en', 'es'] }],
  excludeIndex: true,
  trailingSlash: true,
  targetDirectory: __dirname + '/public',
  pagesDirectory: __dirname + '/src/pages',
});

Sitemap.generateSitemap();

Multiple sitemaps

If the number of urls is more than 50000, then several sitemaps will be automatically created. You can customize the number of urls using sitemapSize

// import { configureSitemap } from '@sergeymyssak/nextjs-sitemap';
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');

const Sitemap = configureSitemap({
  sitemapUrl: 'https://www.example.com',
  sitemapSize: 5000,
  pagesConfig: {
    '/p/*': {
      priority: '0.5',
      changefreq: 'daily',
    },
  },
  nextConfigPath: __dirname + '/next.config.js',
  targetDirectory: __dirname + '/public',
  pagesDirectory: __dirname + '/src/pages',
});

Sitemap.generateSitemap();

Sitemap methods

generateSitemap: () => Promise<ISitemapWriterResultItem[]>;

Generate sitemap

ISitemapWriterResultItem {
  name: string; // sitemap file name
  count: number; // number of urls
}

regenerateSitemapIndex: (sitemapsNames: string[]) => void;

When there are multiple sitemaps, a sitemap index is generated. If we somehow changed our sitemaps externally, then you can use this function to update sitemap index

Sitemap options

domains (optional): IDomain[]

Domain list - same as in next.config.js.

IDomain {
  domain: string; // domain name

}

exclude (optional): string[]

The exclude parameter is an array of glob patterns to exclude static routes / folders from the generated sitemap.

excludeExtensions (optional): string[]

Ignore files by extension.

Example:

// import { configureSitemap } from '@sergeymyssak/nextjs-sitemap';
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');

const Sitemap = configureSitemap({
  // ...

  // ...

Useful information

Language localisation

The value of the hreflang attribute identifies the language (in ISO 639-1 format) and optionally a region (in ISO 3166-1 Alpha 2 format) of an alternate URL.

Gzip

You can gzip your sitemap.xml. The .gz extension just means that it's been compressed (using gzip compression), so that it's smaller and served faster. Most search engine bots can read gzip'd compressed content.
