How do you make your blog stand out? You could start with an awesome design and some great content, but if it doesn't run on the latest technology there's not much point. In this tutorial, I'm going to show how easy building a high-quality application can be by using Fauna as our data layer, Next.js for our frontend framework, and Editor.js as our feature-rich visual editor.
The stack
Fauna
Fauna is a globally distributed, low-latency database that promises to be always consistent and secure. Equipped with native GraphQL support, it allows our application to access data through an API in contrast to traditional databases which require you to open up some sort of connection before being able to use them.
We store all of our blog posts in Fauna. We then use Graphql to fetch a single post or an entire list at once!
Next.js
Next.js is a powerful front-end framework, powered by React. It supports both static pages as well as dynamic content. Next is an excellent candidate to use with Fauna. We can store our data in the database and by using Fauna's Graphql data API we can query our posts data and show them in our frontend.
Editor.js
Text editors are an essential tool for content creators because they help you to edit the information on your browser. If you ever tried building a text editor yourself, then it's clear how difficult this task can be!
For our project, we're using EditorJS - which is simple and easy-to-use with clean JSON output that supports plugins allowing users to extend its functionality even further.
Step 1 - Setup Fauna
Make sure you sign up in Fauna. They have a great free tier you can enroll in for getting started with Fauna. It covers 100k read ops, 50k write ops, 500k compute ops, 5GB storage.
Create a Database
Create a database and generate an admin token by going to the Security tab on the left and then clicking on New Key. Give the new key a name and select the Admin role. Save the token in a safe place we are going to use in our Nex.js application.
Create Your Schema
In the left sidebar click on the GraphQL and after that click on the Import Schema button.
Our Schema looks like the following
type Post {
content: String!
published: Boolean
slug: String!
}
type Query {
allPosts: [Post!]
findPostBySlug(slug: String!): Post
}
Save this schema in a file and when the pop asks to choose a file pick where you saved the schema in it.
Getting familiar with the Endpoint
Create a Post
Now go back to the GraphQL section on the left sidebar and run the following in the GraphQL playground.
mutation CreatePost {
createPost( data:{
content: "Hello World"
slug: "hello-world"
published: true
}){
content
published
slug
}
}
The result should be like the following
On the left sidebar click on collections and you should see a collection called Post, it got created automatically when you imported the schema. You should see a document in that collection with what you just ran in the GraphQL playground.
Fetch a single Post by Slug
In the GraphQL section run the following query
query {
findPostBySlug(slug: "hello-world"){
content
slug
published
}
}
This query fetched a specific blog post using the slug filter.
Fetch all the Posts
In the GraphQL section run the following query
query {
allPosts {
data {
content
published
slug
}
}
}
This query fetches all the posts and returns the content, published status, and slug.
Step 2 - Set up Next.js project
open up your terminal and run:
npx create-next-app fauna-blog
Now enter to the project directory and install the dependencies
cd fauna-blog
npm i @apollo/client apollo-cache-inmemory apollo-client apollo-link-http @bomdi/codebox @editorjs/checklist @editorjs/delimiter @editorjs/editorjs @editorjs/header @editorjs/inline-code @editorjs/list @editorjs/marker @editorjs/paragraph @headlessui/react @heroicons/react @tailwindcss/forms editorjs-react-renderer graphql graphql-tag
TailwindCSS
Please follow the TailwindCSS instructions on how to set it up in your Next.js project.
GraphQL client
We use @apollo/client as the GraphQL client to fetch posts data from the Fauna endpoint and create a post.
Let's create a directory called lib in the root of the project and create a file called apolloClient.js in it.
import {
ApolloClient,
HttpLink,
ApolloLink,
InMemoryCache,
concat,
} from "@apollo/client";
const httpLink = new HttpLink({ uri: process.env.FAUNA_GRAPHQL_ENDPOINT });
const authMiddleware = new ApolloLink((operation, forward) => {
// add the authorization to the headers
operation.setContext(({ headers = {} }) => ({
headers: {
...headers,
authorization:
`Basic ${process.env.FAUNA_TOKEN}`,
},
}));
return forward(operation);
});
const apolloClient = new ApolloClient({
cache: new InMemoryCache(),
link: concat(authMiddleware, httpLink),
});
export default apolloClient;
At the root of the project create a file called .env like the following
FAUNA_GRAPHQL_ENDPOINT="https://graphql.fauna.com/graphql"
FAUNA_TOKEN="YOUR-TOKEN"
Components
In this project, we only have one component for the Editor. In this component
- we create an instance of the Editor.js
- Set it up with its tools and plugins like Header, List, and Paragraph
- Define what we want to do when the editor is
ready, the user makes somechanges, and when the user clicks on thesavebutton. The last step is an important one for us because when the user clicks on the save button we want to send the result to Fauna Endpoint to save the blog post content.

Pages
We are going to have 3 pages
Index.jsis where it shows all the blog posts to the user when they land on our project. Like https://fauna-blog-psi.vercel.app
[slug].jsis a dynamic page where it shows a specific blog post content. Like https://fauna-blog-psi.vercel.app/posts/hello-world
new.jsis Where we can create a new blog post by using EditorJS. Like https://fauna-blog-psi.vercel.app/posts/new
The pages structure should be like the following
Index Page
On this page, we are fetching all the posts from Fauna API and passing them as server-side props to the page. In the getServerSideProps function you can find the GraphQL function.
import gql from "graphql-tag";
import apolloClient from "../lib/apolloClient";
import Link from "next/link";
export default function Home(posts) {
let allPosts = [];
posts.posts.map((post) => {
const content = JSON.parse(post.content);
const published = post.published;
const slug = post.slug;
for (let i = 0; i < content.blocks.length; i++) {
if (
content.blocks[i].type === "header" &&
content.blocks[i].data.level === 2
) {
var title = content.blocks[i].data.text;
break;
}
}
for (let i = 0; i < content.blocks.length; i++) {
if (content.blocks[i].type === "paragraph") {
var description = content.blocks[i].data.text;
break;
}
}
title === undefined ? (title = "Without Title") : (title = title);
description === undefined ? (description = "Without Description") : (description = description);
allPosts.push({
title,
description,
published,
slug,
});
});

}
new.js
On this page, we're importing our instance of the EditorJS and sending the editor's output to the Fauna API to create a post.
We import the EditorJS using NextJS dynamic import because EditJS doesn't work with SSR and it should get imported once the code is running on the client-side.
import dynamic from "next/dynamic";
const Editor = dynamic(
() => import("../../components/editor"),
{ ssr: false }
);
export default function CreatePost() {
return (
<>
<div className="min-h-full">
<div className="bg-gray-800 pb-32">
<header className="py-10">
<div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
<h1 className="text-3xl font-bold text-white">

</div>
</header>
</div>
<main className="-mt-32">
<div className="max-w-7xl mx-auto pb-12 px-4 sm:px-6 lg:px-8">

<div className="bg-white rounded-lg shadow px-5 py-6 sm:px-6">
<div className="border-4 border-dashed border-gray-200 rounded-lg pt-10">
<Editor />
</div>
</div>
{/* /End replace */}
</div>
</main>
</div>
</>
);
}
[slug].js
On this page, we show the specific blog post. We get the blog slug from the query and find the post by its slug using the Fauna API findPostBySlug query. Then we pass the blog data as ServerSideProps. On this page, we use editorjs-react-renderer to render the EditorJS output.
import { useRouter } from "next/router";
import Output from "editorjs-react-renderer";
import gql from "graphql-tag";
import apolloClient from "../../lib/apolloClient";
import Link from "next/link";
export default function Post({ post }) {
const content = JSON.parse(post.content);
return (
<div className="min-h-full">

<Output data={content} />
</div>
</div>
{/* /End replace */}
</div>
</main>
</div>
);
}
export async function getServerSideProps(context) {
const { slug } = context.query;
const { data } = await apolloClient.query({
query: gql`
query Post($slug: String!) {
findPostBySlug(slug: $slug) {
content
published
slug
}
}
`,
variables: {
slug,
},
});
return {
props: {
post: data.findPostBySlug,
},
};
}
Let's See How it Works
Conclusion
In the past, to implement an application's persistent data layer we used to spin up a new server, install our database there, create a schema, load some data, and in our application, by using a client we could operate CRUD. But as we've seen in this article with Fauna in a couple of minutes we could create our database and an API for our data to use in NextJS without worrying about provisioning a server, configuring the database, and having the operational overhead.
What we built in this article is a great example of how you can reduce your development time by using Fauna and Nextjs for developing complex systems like Blogging Application from scratch.
