React SEO Tools
This library for React-based websites and applications can be used for 3 things:
- generating SEO-related tags for the HTML
<head>section - generating a
robots.txtfile for search engine crawlers - generating a
sitemap.xmloverview of URLs
It works especially well with the Next.js framework.
Installation
Yarn
yarn add react-seo-toolsNPM
npm install react-seo-toolsImports
// This imports the entire bundle via this library's index file,
// which might inflate your own website's bundle size a small bit
// (unless your frontend build tool uses tree shaking)
import { generateHeadTags, generateRobotsTxt, generateSitemapXml } from 'react-seo-tools';
// Therefore, each of these utilities can also be imported from their own file
import { generateHeadTags } from 'react-seo-tools/lib/generateHeadTags';
import { generateRobotsTxt } from 'react-seo-tools/lib/generateRobotsTxt';
import { generateSitemapXml } from 'react-seo-tools/lib/generateSitemapXml';Usage
GenerateHeadTags (API Options)
This function generates an array of elements which can be inserted into the <head> section of your HTML page.
If you're using Next.js,
you would render these elements inside a pair of <Head></Head> tags, as shown by the example below.
If you're not using Next.js,
you might want to add the react-helmet library to your project,
so you can render these head elements inside a pair of <Helmet></Helmet> tags.
import Head from 'next/head';
import { generateHeadTags } from 'react-seo-tools/lib/generateHeadTags';
export default function ArticlePage() {
return (
<div>
<Head>
{generateHeadTags({
title: 'Website - Articles - How to SEO',
description: 'Want to learn SEO with React? Look no further!',
openGraph: {
type: 'article',
title: 'How to SEO',
image: 'https://www.example.com/how-to-seo.jpg',
'article:author': 'Jessy',
'article:tag': ['react', 'seo'],
'article:published_time': '2020-12-31',
},
})}
</Head>
<main>
<h1>How to SEO</h1>
<p>...</p>
</main>
</div>
);
}

**********************/GenerateRobotsTxt (API Options)
This function generates a string which can be served as your website's robots.txt file.
Here's how you would use it in a Next.js lambda.
import { NextApiRequest, NextApiResponse } from 'next';
import { generateRobotsTxt } from 'react-seo-tools/lib/generateRobotsTxt';
export default function (req: NextApiRequest, res: NextApiResponse) {
const robotsTxt = generateRobotsTxt({
policy: {
userAgent: '*',
allow: '/',
},
sitemap: 'http://localhost:8080/sitemap.xml',
});
res.setHeader('Content-Type', 'text/plain');
res.end(robotsTxt);
}
/**********************
User-agent: *
Allow: /
Sitemap: http://localhost:8080/sitemap.xml
**********************/And here's how you'd use it with Express (Node).
const express = require('express');
const { generateRobotsTxt } = require('react-seo-tools/lib/generateRobotsTxt');
const app = express();
app.get('/robots.txt', (req, res) => {
const robotsTxt = generateRobotsTxt({
policy: {
userAgent: '*',
allow: '/',
},
sitemap: 'http://localhost:8080/sitemap.xml',
});
res.type('text/plain').end(robotsTxt);
});
app.listen(8080);
/**********************

Allow: /
Sitemap: http://localhost:8080/sitemap.xml
**********************/GenerateSitemapXml (API Options)
This function generates a string which can be served as your website's sitemap.xml file.
Here's how you would use it in a Next.js lambda.
import { NextApiRequest, NextApiResponse } from 'next';
import { generateSitemapXml, Changefreq } from 'react-seo-tools/lib/generateSitemapXml';
export default function (req: NextApiRequest, res: NextApiResponse) {
const sitemapXml = generateSitemapXml({

{ loc: '' },
{ loc: '/articles', lastmod: '2020-12-31', changefreq: Changefreq.daily },
{ loc: '/articles/123', lastmod: '2020-12-31', changefreq: Changefreq.monthly },
],
});
res.setHeader('Content-Type', 'application/xml');
res.end(sitemapXml);
}
