In this tutorial, you will learn how to render content using Strapi's Rich Text Block Editor in a Next.js project.

Instead of building your project from scratch, I already have a repo with the example.

To save time, you will walk you through the example project and explain all the important details so you can get started with the new block renderer in your project.

Setting Up The Example Repo

You can find the example project here.

Start by cloning the repo with the following command.

Clone Github Repo and Setup Project

Ensure you have Github CLI installed.

gh repo clone PaulBratslavsky/strapi-block-renderer-test

Once you have the project cloned, run the following commands to set up all the project dependencies.

cd strapi-block-renderer-test
yarn setup

🖐️ NOTE: You might need to run yarn install for the above command to work.

Create Environment Variables File

Once all the dependencies are installed, you need to add a .env file inside your Strapi project. Navigate to the backend folder, create a new .env file, and add the following:

1HOST=0.0.0.0
2PORT=1337
3APP_KEYS=wXYvvOuO1EkHdx649y6VSw==,ybhl4JrYJCywPzD9/VCCHA==,ny2t0th9YSjS4CboaL5gaw==,4QqGB4RyQfuE/2QraXLUaw==
4API_TOKEN_SALT=ZZr3P8+Wb32+onN+nqki2A==
5ADMIN_JWT_SECRET=FuI/5Q6dpK3WIrmQjgy9RA==
6TRANSFER_TOKEN_SALT=sCUHUXnyxPfDyDtpNBy9Yw==
7JWT_SECRET=BcnO4bwwIbp3XwyVnDONpQ==

Seed Dummy Data for your Project

Once that is done. You will have to seed your dummy data so you have something to work with.

Change directory to the root of your project and run the following command.

yarn seed

yarn seed
yarn run v1.22.19**

$ cd backend && yarn strapi import -f ../seed-data.tar.gz
$ strapi import -f ../seed-data.tar.gz

? The import will delete your existing data! Are you sure you want to proceed?(y/N)

You will see the following message; just go ahead and click yes.

Start Project Frontend and Backend

Once everything is done, you can start both frontend and backend projects by running the following command.

yarn dev

Your Strapi project will start on http://localhost:1337/admin go ahead and create your first admin user.

Once done, you will be greeted with the dashboard.

If you navigate to Content Manager -> Note, you will see us using the new Strapi's Rich Text Editor.

You can find it as one of the options when building your collection type.

And finally open tour frontend project in your browser by going to http://localhost:3000 and you will seeyour article being displayed.

Now that your project is working. Review the implementation details in the code.

Take a Look At The Code

Go ahead and open your project in Vs Code if you haven't already done so. And take a look at the following file found in frontend/src/app/page.tsx

page.tsx

1import { type BlocksContent } from "@strapi/blocks-react-renderer";
2import BlockRendererClient from "./BlockRendererClient";
3
4async function getStrapiData() {
5  const res = await fetch("http://localhost:1337/api/notes");
6  const data = await res.json();
7  return data;
8}
9
10export default async function Home() {
11  const { data } = await getStrapiData();
12
13  const content: BlocksContent = data[0].content;
14
15  return (
16    <main className="max-w-[980px] mx-auto my-36">
17      <h1>{data[0].title}</h1>
18      <BlockRendererClient content={content} />
19    </main>
20  );
21}

In the code above. In Next.js. This defaults to RSC (React Server Component), which is why you are able to fetch the data directly via the getStrapiData() function, which is pretty cool.

1async function getStrapiData() {
2  const res = await fetch("http://localhost:1337/api/notes");
3  const data = await res.json();
4  return data;
5}

You can call it from your component.

1export default async function Home() {
2  const { data } = await getStrapiData();
3  
4  // the rest of the code
5  ...
6}

Once you get the data, you save it to a content variable and pass it to your BlockRendererClient component.

1export default async function Home() {
2  const { data } = await getStrapiData();
3  const content: BlocksContent = data[0].content;
4  
5  // the rest of the code
6  ...
7}

Before you take a look at the BlockRendererClient component, here is a brief note on Next.js 14, which can be learned here

In short, Strapi's BlocksRenderer component relies on client-side javascript.

That is why you must wrap it inside your BlockRendererClient and use the "use client" directive at the top of the page.

Take a Look At Strapi's BlocksRenderer

You can find the implementation of your BlockRenderer inside the /frontend/src/app/BlockRendererClient.tsx file.

BlockRendererClient.tsx

1"use client";
2import Image from "next/image";
3
4import {
5  BlocksRenderer,
6  type BlocksContent,
7} from "@strapi/blocks-react-renderer";
8
9export default function BlockRendererClient({
10  content,
11}: {
12  readonly content: BlocksContent;
13}) {
14  if (!content) return null;
15  return (
16    <BlocksRenderer
17      content={content}
18      blocks={{
19        image: ({ image }) => {
20          console.log(image);
21          return (
22            <Image
23              src={image.url}
24              width={image.width}
25              height={image.height}
26              alt={image.alternativeText || ""}
27            />
28          );
29        },
30      }}
31    />
32  );
33}

You can read more about the BlockRenderer here to get all the details, steps, and outlines on how to install and set it up in your project.

But you will learn the basics here.

You already have it installed, but if you were to install it in your own project, you would do it with the following command.

yarn add @strapi/blocks-react-renderer

For straight-forward implementation, all you would need to do is just import your component and use it by passing in the block data that you are getting from your API call.

1"use client";
2import {
3  BlocksRenderer,
4  type BlocksContent,
5} from "@strapi/blocks-react-renderer";
6
7export default function BlockRendererClient({
8  content,
9}: {
10  readonly content: BlocksContent;
11}) {
12  if (!content) return null;
13  return <BlocksRenderer content={content} />;
14}

But you can overwrite the default blocks.

In the example below, you will take a look at how you can replace the default with using Next.js Image component.

You can learn more about all the other options here.

But here are all the options available to you for blocks props:

• Blocks are full-width elements, usually at the root of the content. The available options are:
  • paragraph
  • heading (receives level)
  • list (receives format)
  • quote
  • code (receives plainText)
  • image (receives image)
  • link (receives url)

You are going to modify your code with the following.

1<BlocksRenderer
2  content={content}
3  blocks={{
4    image: ({ image }) => {
5      console.log(image);
6      return (
7        <Image
8          src={image.url}
9          width={image.width}
10          height={image.height}
11          alt={image.alternativeText || ""}
12        />
13      );
14    },
15  }}
16/>

Inside the BlockRenderer, you are passing an object where you are overwriting the image block with your custom Next.js Image component.
