Documentation
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:
āāā src
āāā pages
āāā projects
ā āāā computers
ā ā āāā laptop.js
ā ā āāā pc.js
ā āāā phones
ā āāā android.js
ā āāā ios.js
āāā admin
ā āāā account.js
ā āāā cms.js
āāā index.js
All static routes from pages folder will be automatically added to the 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).
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();
Example of exportPathMap in next.config.js
module.exports = {
i18n: {
domains: [
{
domain: 'example.com',
defaultLocale: 'en',
locales: ['en-US', 'en-CA'],
},
],
},
trailingSlash: true,
exportPathMap: async function () {
return {
'/': { page: '/' },
'/admin': { page: '/admin' },
'/p/learn-nextjs': { page: '/post', query: { title: 'learn-nextjs' } },
};
},
};

With dynamic routes
For dynamic routes, you have to declare them with the include property.
Example src folder:
āāā src
āāā pages
āāā project
ā āāā [id].js
āāā index.js
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.
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
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();
Look at public directory
āāā src
āāā public
āāā sitemap.xml
āāā sitemap1.xml
āāā sitemap2.xml
āāā sitemap3.xml
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
defaultLocale?: string; // non-routing language
locales?: string[]; // routing languages
http?: boolean; // http or https
}
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:
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');
const Sitemap = configureSitemap({
excludeExtensions: ['.ts'],
});
Sitemap.generateSitemap();
excludeIndex (optional): boolean
Remove index from URL, directory will be ending with the slash. Defaults to true.
include (optional): string[]
Array of extra paths to include in the sitemap. If you want to add any route with dynamic parameters, you have to set an array of dynamic routes.
Example:
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');
const Sitemap = configureSitemap({
include: ['/project/1', '/project/2'],
exclude: ['/project/[id]'],
});
Sitemap.generateSitemap();
trailingSlash (optional): boolean
Add trailing slashes. Defaults to false.
nextConfigPath (optional): string
Use exportPathMap from next.config.js file.
pagesConfig (optional): IPagesConfig[]
Object configuration of priority and changefreq per route / folder.
IPagesConfig {
[key: string]: {
priority: string,
changefreq: string
}
}
Example:
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');
const Sitemap = configureSitemap({
pagesConfig: {
'/about': {
priority: '0.5',
changefreq: 'daily',
},
'/project/*': {
priority: '0.9',
changefreq: 'daily',
},
},
});
Sitemap.generateSitemap();
pagesDirectory (required): string
The directory where there are Next.js pages.
targetDirectory (required): string
The path to the public folder.
sitemapUrl (optional): string
The url which will be specified in the sitemap index file.
sitemapSize (optional): number

sitemapStylesheet (optional): ISitemapStylesheet[]
Array of style objects that will be applied to sitemap.
ISitemapStylesheet {
type: string;
styleFile: string;
}
Example:
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');
const Sitemap = configureSitemap({
sitemapStylesheet: [
{
type: "text/css",
styleFile: "styles/styles.css"

Sitemap.generateSitemap();
Useful information
-
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.
-
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.
Look at code how you can generate sitemap.xml.gz
const zlib = require('zlib');
const fs = require('fs');
const { configureSitemap } = require('@sergeymyssak/nextjs-sitemap');
async function getDynamicPaths() {
const data = ['house', 'flower', 'table'];
return data.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().then(() => {
const inp = fs.createReadStream('public/sitemap.xml');
const out = fs.createWriteStream('public/sitemap.xml.gz');
const gzip = zlib.createGzip();
inp.pipe(gzip).pipe(out);
fs.unlink('public/sitemap.xml', () =>
console.log('Sitemap.xml has been deleted!'),
);
console.log('Sitemap.xml.gz has been created!');
});
});
