Inline Images

Using Next.js Image component for inline images and media entities in body fields.


To replace inline images and media entities added via a WYSIWYG editor, we can use an html parser to replace the img tags with the Next.js Image component.

Dependencies

Install html-react-parser.

yarn add html-react-parser

Component

Let's create a component to render a text_long (example: node.body.processed) field type.

components/body.tsx
import { HTMLReactParserOptions } from "html-react-parser"
import { Element } from "domhandler/lib/node"
import parse from "html-react-parser"
import Image from "next/image"
const options: HTMLReactParserOptions = {
replace: (domNode) => {
if (domNode instanceof Element && domNode.name === "img") {
const { src, alt, width, height } = domNode.attribs
return (
<Image
src={`${process.env.NEXT_PUBLIC_DRUPAL_BASE_URL}/${src}`}
width={`${width}px`}
height={`${height}px`}
alt={alt}
layout="intrinsic"
objectFit="cover"
/>
)
}
},
}
export function Body({ value }: { value: string }) {
return <>{parse(value, options)}</>
}

We use intrinsic layout so that images scale down for smaller viewports but maintain the original dimensions for larger viewports.

Usage

pages/index.tsx
import { Body } from "components/body"
export default function Page({ node }) {
return (
<div variant="container">
<h1>{node.title}</h1>
<Body value={node.body.processed} />
</div>
)
}
