WordPress has existed for over two decades, powering 42.7% of all the internet pages on the Internet, consistent with W3Techs. It moreover holds a 62.5% market percentage for content material subject material keep an eye on tactics (CMSs) behind internet pages.

Today, many programming languages and frameworks are available to build user-friendly, high-performance internet pages which can be method faster than WordPress, it doesn’t subject what optimization you do for your WordPress dashboard. One example is Subsequent.js, a popular React framework.

This data displays simple find out how to use WordPress as a headless CMS, providing data for your Next.js device. It moreover explains deploying your Next.js code as a static web site to Kinsta’s free Static Website Internet hosting supplier.

Understanding headless WordPress

Headless WordPress refers to using WordPress just for its backend options — managing and storing content material subject material — and using a separate system, like Next.js, for the frontend presentation.

This decoupling lets in developers to use WordPress’s tough content material subject material keep an eye on apparatus while taking whole advantage of stylish frontend development choices, comparable to server-side rendering and static internet web page generation in Next.js.

Making able your WordPress internet web page

Forward of diving into the Next.js development, your WordPress internet web page needs a little bit of of preparation to serve as a headless CMS.

While you don’t already have a WordPress internet web page, you’ll be capable to create one merely with Kinsta. There are 3 tips about the best way to assemble a WordPress internet web page using Kinsta:

1. Create a internet web page to your native device (possibly using our DevKinsta equipment) previous to shifting the internet web page to our servers
2. Create a internet web page remotely using the MyKinsta dashboard
3. Create a internet web page remotely using the Kinsta API

Upon getting a WordPress internet web page, there are two approaches to fetching data from your WordPress CMS into your frontend framework: WPGraphQL and REST API.

The REST API facilitates data retrieval in JSON construction using JavaScript approaches identical to the Fetch API or the Axios library. The REST API has been built into WordPress since type 4.7, because of this it does not require any plugin to artwork. Then again to use WPGraphQL, which helps you to interact in conjunction with your WordPress data using GraphQL query, you’ll have to arrange the WPGraphQL plugin.

Let’s use the REST API for this knowledge. To get your WordPress data in a JSON construction, append /wp-json/wp/v2 for your WordPress internet web page URL:

http://yoursite.com/wp-json/wp/v2

If the JSON API isn’t enabled when you seek advice from http://yoursite.com/wp-json by means of default, you’ll be capable to permit it by means of opening Permalinks beneath Settings throughout the WordPress dashboard and selecting Submit Identify or every other surely certainly one of your variety aside from Easy:

This works for local and public WordPress internet sites, offering endpoints for content material subject material that comprises posts, pages, feedback, and media. Be informed our entire information to the REST API to be informed further.

Setting up your Next.js environment

Next.js helps developers assemble web techniques with ease, making improvements to capability and optimizing the advance experience. One in all its key choices is file-based routing, which simplifies the arrival of routes.

Next.js moreover focuses intently on capability, offering choices comparable to computerized code splitting, which fairly a little bit best the vital JavaScript for each internet web page, significantly lowering the burden time.

To prepare a Next.js project, you’ll be capable to run the following command and use its default responses:

npx create-next-app@latest nextjs-wp-demo

For this knowledge, you’ll be capable to clutch our Git starter template by means of following the ones steps:

1. Visit this project’s GitHub repository.
2. Choose Use this template > Create a brand spanking new repository to copy the starter code proper right into a repository within your GitHub account (check out the sphere to include all branches).
3. Pull the repository for your local pc and switch to the starter-files division using the command: git checkout starter-files.

4. Arrange the vital dependencies by means of operating the command npm arrange.

As quickly because the arrange is whole, unlock the project for your local pc with npm run dev. This makes the project available at http://localhost:3000/.

Understanding the project

The App Router was offered in Next.js 13, converting the present pages checklist for routing. Routing with the App Router moreover involves rising folders within the app checklist. Then, you nest a internet web page.js file within the right kind folder to stipulate your direction.

In this project, app is the core checklist you could be interacting with, and also you’re going to to search out the following file development.

/
|-- /app
    |-- /blog
        |-- /[postId]
        	|-- internet web page.js
        |-- internet web page.js
    |-- globals.css
    |-- construction.js
    |-- navbar.js
    |-- internet web page.js

3 pages are created: the home internet web page to turn basic knowledge, the blog internet web page to turn all posts from your WordPress CMS, and the dynamic internet web page ([postId]/internet web page.js) for rendering specific individual posts.

You’re going to moreover understand the navbar.js component, which is imported into the construction.js file to create a construction for the project.

Fetching data from WordPress to Next.js

With the WordPress REST API, you’ll be capable to fetch posts, pages, and custom designed post types by means of sending HTTP requests to specific endpoints.

Let’s make a fetch request throughout the blog/internet web page.js file to fetch all posts for your WordPress CMS and then in the end make a request to fetch each post dynamically throughout the blog/[postId]/internet web page.js in line with the identification parameter passed.

Forward of we make the ones requests, it’s good practice so to upload your JSON API maintain to an environment variable. This implies promises your API base URL is for sure configurable and not hardcoded right through a couple of data.

Create a .env file throughout the root of your Next.js project and add the following:

NEXT_PUBLIC_WORDPRESS_API_URL=https://yoursite.kinsta.cloud/wp-json/wp/v2

You should definitely change the URL in conjunction with your internet web page’s JSON API. Moreover, add .env for your .gitignore file so it does not push the file for your Git provider.

Fetch all posts from WordPress to Next.js

To fetch all posts from your WordPress internet web page, create an asynchronous function named getPosts for your blog/internet web page.js file. This function uses the Fetch API to make a GET request to the /posts endpoint of your WordPress REST API.

async function getPosts() {
    const response = look ahead to fetch(
        `${process.env.NEXT_PUBLIC_WORDPRESS_API_URL}/posts`
    );
    const posts = look ahead to response.json();
    return posts;
}

Upon receiving the response, it converts the response to JSON, building an array of post devices. The ones posts may also be rendered for your Next.js device, providing a dynamic tick list of blog posts fetched straight away from WordPress.

const BlogPage = async () => {
    const posts = look ahead to getPosts();
    return (
        

            
All Blog Posts
            
All blog posts are fetched from WordPress by way of the WP REST API.
            

                {posts.map((post) => {
                    return (
                        
                            
{post.identify.rendered}
                            

                        
                    );
                })}
            
        
    );
};

All through the Next.js internet web page component, identify getPosts asynchronously to fetch the posts. Then, map over the array of posts, rendering each post’s identify and excerpt within a component.

This not best displays the posts however as well as wraps each in a link that navigates to an extensive view of the post. This is achieved by means of using Next.js’s file-based routing, where the post ID is used to generate the URL path dynamically.

Fetch dynamic posts from WordPress to Next.js

Inside the code above, each post is wrapped in a link that is expected to help consumers navigate to an extensive view of the post.

For specific individual post pages, you use dynamic routing in Next.js to create a internet web page that fetches and displays a single post in line with its ID. A dynamic internet web page [postID]/internet web page.js is already created throughout the stater-files code.

Create a getSinglePost function, similar to getPosts, to fetch a single post using the post ID passed as a parameter.

async function getSinglePost(postId) {
    const response = look ahead to fetch(
        `${process.env.NEXT_PUBLIC_WORDPRESS_API_URL}/posts/${postId}`
    );
    const post = look ahead to response.json();
    return post;
}

Inside the dynamic internet web page component, you extract the post ID from the URL parameters, identify getSinglePost with this ID, and render the post’s content material subject material.

const internet web page = async ({ params }) => {
    const post = look ahead to getSinglePost(params.postId);
    // ... the rest of the internet web page code
};

You’ll then populate the internet web page with the fetched data:

const internet web page = async ({ params }) => {
    const post = look ahead to getSinglePost(params.postId);
    if (!post) {
        return 
Loading...
;
    }
    return (
        

            
{post.identify.rendered}
            

                
 dangerouslySetInnerHTML={{ __html: post.content material subject material.rendered }}>
            
        
    );
};

You’ll get right to use the entire code on our GitHub repository.

Deploying your Next.js device to Kinsta at no cost

Kinsta’s Static Website Internet hosting supplier supplies the ability to host up to 100 static internet sites for free.

This supplier hosts merely static data. While you use a static web site generator like Next.js, you’ll be capable to configure possible choices that assemble your project from GitHub and deploy the static data to Kinsta.

Static rendering in Next.js

To permit a static export in Next.js type 13 above, trade the output mode inside next.config.js:

const nextConfig = {
    output: 'export',
};

Now, when you assemble your project, Next.js is anticipated to supply an out folder that comprises the HTML, CSS, and JavaScript property for your device.

From type 13, Next.js has supported starting as a static internet web page, then later optionally upgrading to use choices that require a server. When you use server choices, building your pages won’t generate static pages.

For instance, throughout the dynamic direction, you could be fetching the ones data dynamically. You need so as to generate all the posts statically. This may also be performed using the generateStaticParams function.

The function is used in mixture with dynamic direction segments to statically generate routes at assemble time as a substitute of on-demand at request time. When you assemble, generateStaticParams runs previous to the corresponding layouts or pages are generated.

In [postID]/internet web page.js, use the generateStaticParams function to get all posts direction:

export async function generateStaticParams() {
    const response = look ahead to fetch(
        `${process.env.NEXT_PUBLIC_WORDPRESS_API_URL}/posts`
    );
    const posts = look ahead to response.json();

    return posts.map((post) => ({
        postId: post.identification.toString(),
    }));
}

When you run the assemble command, your Next.js project will now generate an out checklist with the static data.

Deploy Next.js to Kinsta static internet web page web page internet hosting

Push your codes for your preferred Git provider (Bitbucket, GitHub, or GitLab). Next, practice the ones steps to deploy your Next.js static internet web page to Kinsta:

1. Log in or create an account to view your MyKinsta dashboard.
2. Authorize Kinsta in conjunction with your Git provider.
3. Click on on Static Internet sites on the left sidebar, then click on on Add internet web page.
4. Choose the repository and the dept you wish to have to deploy from.
5. Assign a unique determine for your internet web page.
6. Add the assemble settings throughout the following construction:
   • Assemble command: npm run assemble
   • Node type: 18.16.0
   • Post checklist: out

7. In spite of everything, click on on Create internet web page.

And that’s it! You right now have a deployed internet web page within a few seconds. A link is equipped to get right to use the deployed type of your internet web page. You’ll later add your customized area and SSL certificates if you wish to have.

As an alternative to static internet web page web page internet hosting, you’ll be ready to make a choice to deploy your static internet web page with Kinsta’s Utility Internet hosting supplier, which provides higher web page internet hosting flexibility, a wider range of benefits, and get right to use to further tough choices — like scalability, customized deployment using a Dockerfile, and complete analytics encompassing real-time and historic data. You moreover don’t need to configure your Next.js project for static rendering.

Summary

In this article, you’ve were given discovered simple find out how to leverage headless WordPress in a Next.js project to fetch and display posts dynamically. This implies permits the seamless integration of WordPress content material subject material into Next.js techniques, offering a modern and dynamic web experience.
