Sitemap generator for Remix applications
robots.txtnpm i remix-sitemap
// entry.server.tsx
import { createSitemapGenerator } from 'remix-sitemap';
// Step 1. setup the generator
const { isSitemapUrl, sitemap } = createSitemapGenerator({
siteUrl: 'https://example.com',
generateRobotsTxt: true
// configure other things here
})
export default async function handleRequest(
request: Request,
responseStatusCode: number,
responseHeaders: Headers,
remixContext: EntryContext
) {
// Step 2. add the sitemap response
if (isSitemapUrl(request))
return await sitemap(request, remixContext);
let markup = renderToString(
<RemixServer context={remixContext} url={request.url} />
);
responseHeaders.set('Content-Type', 'text/html');
return new Response('<!DOCTYPE html>' + markup, {
status: responseStatusCode,
headers: responseHeaders
});
}
lib/sitemap.ts file// lib/sitemap.ts
export const { experimental_sitemap, robots } = createSitemapGenerator({
siteUrl: 'https://example.com',
// configure other things here
})
sitemap[.]xml route// app/routes/sitemap[.]xml.tsx
import { routes } from '@remix-run/dev/server-build';
import { experimental_sitemap } from '~/lib/sitemap';
export const loader: LoaderFunction = async ({ request }) => {
return await experimental_sitemap(request, routes);
}
robots[.]txt route// app/routes/robots[.]txt.tsx
import { robots } from '~/lib/sitemap';
export const loader: LoaderFunction = ({ request }) => {
return robots();
}
Create a remix-sitemap.config.js file at the project root
/** @type {import('remix-sitemap').Config} */
module.exports = {
siteUrl: 'https://example.com',
generateRobotsTxt: true
// configure other things here
}
Add a script using remix-sitemap to package.json to run after build.
For example if you are using npm-run-all
{
"scripts": {
"build": "npm-run-all build:*",
"build:remix": "remix build",
"build:sitemap": "remix-sitemap"
}
}
If you are using build time generation, the request will be empty
// app/routes/posts.$slug.tsx
import type { SitemapFunction } from 'remix-sitemap';
export const sitemap: SitemapFunction = ({ config, request }) => {
const posts = await getPosts();
return posts.map(post => ({
loc: `/posts/${post.slug}`,
lastmod: post.updatedAt,
exclude: post.isDraft, // exclude this entry
// acts only in this loc
alternateRefs: [
{
href: `${config.siteUrl}/en/posts/${post.slug}`,
absolute: true,
hreflang: 'en'
},
{
href: `${config.siteUrl}/es`,
hreflang: 'es'
}
]
}));
};
// app/routes/private.tsx
import type { SitemapFunction } from 'remix-sitemap';
export const sitemap: SitemapFunction = () => ({
exclude: true
})
Url set can contain additional sitemaps defined by google. These are Google news, image or video.
You can add these sitemaps in sitemap function by adding the news, images or videos property.
export const sitemap: SitemapFunction = () => ({
images: [{ loc: 'https://example.com/example.jpg' }],
news: [{
title: 'Random News',
date: '2023-03-15',
publication: {
name: 'The Example Times',
language: 'en'
}
}]
});
If you have a lot of urls, you can split the sitemap in multiple files. You can do this by setting the size property in the config.
This is only available in build time generation
/** @type {import('remix-sitemap').Config} */
module.exports = {
siteUrl: 'https://example.com',
size: 10000
}
you have two ways to cache the sitemap, the first one is using the Cache-Control header
This is only available in runtime generation
createSitemapGenerator({
siteUrl: 'https://example.com',
headers: {
'Cache-Control': 'max-age=3600'
}
})
and the second one is using the cache property in the config
createSitemapGenerator({
siteUrl: 'https://example.com',
cache: {
get: async () => {
return await redis.get('sitemap') || null;
},
set: async (sitemap) => {
await redis.set('sitemap', sitemap, 'EX', 3600);
}
}
})
