Have you ever wanted to build a server-rendered, SEO-friendly website using and Node.js? The typical solutions for achieving this are either using a pre-rendering service like Prerender.io, or implementing server-side rendering of React components. React A relatively new alternative is , a framework for building universal React webapps. Next.js provides out-of-the-box for server-side rendering including setting HTML tags for SEO and fetching data before rendering components. Read more about the philosophy behind Next.js . Next.js tools here In this tutorial we are going to show you how to build a CMS-powered blog using , , and . The finished code for this tutorial is . React Next.js ButterCMS available on Github is an . You can think of Butter as similar to WordPress except that you build your website in your language of choice and then plug-in the dynamic content using an API. You can try for yourself by . ButterCMS API-based CMS and content API ButterCMS signing in with Github Getting Started Create a new directory for your app and add a package.json file: {"name": "react-blog"} Install Next.js and React. As of the time of this writing, we’ll want to install the Next.js so we can setup dynamic routes later: npm install next@beta react react-dom --save Then add a script to your package.json: { "scripts": { "start": "next" }} Next.js treats every js file in the directory as a page. Let's setup a basic homepage by creating a inside your project: ./pages ./pages/index.js export default () => ( <div>My blog homepage</div>) And then just run and go to . npm run start http://localhost:3000 Finally, create a and make sure it loads at : ./pages/post.js [http://localhost:3000/post](http://localhost:3000/post:) export default () => ( <div>A blog post</div>) Fetching blog posts Next we’ll integrate so we can fetch and render blog posts dynamically. ButterCMS First install the and restart your server: ButterCMS Node.js API client npm install buttercms --save We’ll update to be a React component that fetches and displays posts using the ButterCMS SDK: index.js import React from 'react'import Link from 'next/link'import Butter from 'buttercms'const butter = Butter('de55d3f93789d4c5c26fb07445b680e8bca843bd')export default class extends React.Component { static async getInitialProps({ query }) { let page = query.page || 1; const resp = await butter.post.list({page: page, page_size: 10}) return resp.data; } render() { const { next_page, previous_page } = this.props.meta; return ( <div> {this.props.data.map((post) => { return ( <div> <a href={`/post/${post.slug}`}>{post.title}</a> </div> ) })} <br /> <div> {previous_page && <Link href={`/?page=${previous_page}`}><a>Prev</a></Link>} {next_page && <Link href={`/?page=${next_page}`}><a>Next</a></Link>} </div> </div> ) }} With Next.js will execute on the server on initial page loads, and then on the client when navigating to a different routes using the built-in component. also receives a context object with various properties – we access the property for handling pagination. We are fetching posts from a ButterCMS test account – sign in with Github to setup your own posts. getInitialProps <Link> getInitialProps query In our method we use some clever syntax to only display pagination links only when they're applicable. Our post links will take us to a 404 – we'll get these working next. render() Displaying posts To get our post links working we need to setup dynamic routing for our blog posts. Create a custom server that routes all URLs to our post component: ./server.js /post/:slug const { createServer } = require('http')const { parse } = require('url')const next = require('next')const dev = process.env.NODE_ENV !== 'production'const app = next({ dev })const handle = app.getRequestHandler()app.prepare().then(() => { createServer((req, res) => { // Be sure to pass `true` as the second argument to `url.parse`. // This tells it to parse the query portion of the URL. const parsedUrl = parse(req.url, true) const { pathname, query } = parsedUrl if (pathname.includes('/post/')) { const splitPath = pathname.split("/"); // Add post slug to query object query.slug = splitPath[2]; app.render(req, res, '/post', query) } else { handle(req, res, parsedUrl) } }) .listen(3000, (err) => { if (err) throw err console.log('> Ready on http://localhost:3000') })}) We’ll also update our post component to fetch blog posts via slug and render the title and body: import React from 'react'import Butter from 'buttercms'const butter = Butter('de55d3f93789d4c5c26fb07445b680e8bca843bd')export default class extends React.Component { static async getInitialProps({ query }) { const resp = await butter.post.retrieve(query.slug); return resp.data; } render() { const post = this.props.data; return ( <div> <h1>{post.title}</h1> <div dangerouslySetInnerHTML={{__html: post.body}} /> </div> ) }} Finally, update our start script to use our customer server and restart: package.json "scripts": { "start": "node server.js"} SEO Next.js provides a component for setting HTML titles and meta tags. Add to the top of and use the component in the method: <Head> import Head from 'next/head' ./pages/post.js render() render() { const post = this.props.data; return ( <div> <Head> <title>{post.seo_title}</title> <meta name="description" content={post.meta_description} /> <meta name="og:image" content={post.featured_image} /> </Head> <h1>{post.title}</h1> <div dangerouslySetInnerHTML={{__html: post.body}} /> </div> )} Restart the server and inspect the HTML source of a post to verify that tags are getting set correctly.
