Prismic Rich (💰) Text, for React

A simple utility to render Rich Text with Prismic API V2

Prismic provides content writers with a WYSIWYG editor. It's awesome for formatting text but harder to deal with on client side. Fortunately, Prismic React provides utilities to tackle this exact issue!

Based on prismic-richtext, it allows you to render Prismic generated Rich Text as React components. It's meant to work in pair with the prismic-javascript library, a new javascript kit for the prismic API v2 available here.

Installation

Prismic Api Endpoint

First and foremost, make sure you're using the V2 API. Your prismic-configuration.js (or equivalent) should probably contain a line like this one (or equivalent) 👇

apiEndpoint: your-repo-name.prismic.io/api/v2

Consider polyfilling:

NPM

👇 Prismic React is on npm...

npm install prismic-reactjs --save

CDN

... and on CDN!

https://unpkg.com/prismic-reactjs

(You may need to adapt the version number)

Downloadable version

You'll find downloadable versions on our release page: https://github.com/prismicio/prismic-reactjs/releases.

The kit is universal, it can be used:

  • Server-side with NodeJS
  • Client-side as part of your build with Browserify, Parcel, webpack...
  • Client-side with a simple script tag

Usage

Although this package is mainly about RichText, Prismic React exposes 3 utilities. Import them in your project this way:

import {Date, Link, RichText} from 'prismic-reactjs';

Date utility

Like Link, Date is directly imported from prismic-helpers. It converts a Date string received from the API, to an ISO (8601) Javascript Date (ie. something you're used to work with):

Date(mydoc.data.mydate)

Link utility

Link generates links to documents within your website (and outside). Give it a Link fragment and you'll get a full fledged url:

Link.url(mydoc.data.mylink, ctx.linkResolver)

👆Note that linkResolver argument is not required if you are 100% sure that your're not linking to a document !

RichText Component

RichText is a simple React component used to render a Rich Text. If you've been used to work with RichText.render, you're pretty much good to go!

Basic example

This is the most basic way to make it work, where myDoc.data.title is (obviously) a Rich Text object. linkResolver will be triggered everytime RichText meets a link and wants to correctly resolve it.

  import { RichText } from 'prismic-reactjs';
 
  // Use linkResolver if you *actually* have links
  const linkResolver = (doc) => {
    switch (doc.type) {
        case ('homepage'): return '/'
    }
  }
 
  const Header = (myDoc) => (
    <header>
        <RichText
            render={myDoc.data.title}
            linkResolver={linkResolver}
        />
    </header>
  );
  export default Header;

As text

Occasionally, you may require to render not a component, but a simple string. Use RichText's static property asText to do so:

  const Title = (myDoc) => (
    <h1>
        {RichText.asText(myDoc.data.title)}
    </h1>
  )

Creating a custom Link

Under the hood, prismic-richtext takes your rich text data and serializes it. Based on your data type (ie. heading, paragraph, list, link...), it creates an HTML template and renders it as a React component. Most of the time, it's enough: a list will always be a list. But if you work with React, you'll probably want to render Prismic links as React router dom Link instead of <a> tags. We created a property called serializeHyperlink, just for that:

const myCustomLink = (type, element, content, children, index) => (
  <Link key={element.data.id} to={linkResolver(element.data)}>
    <a>{content}</a>
  </Link>
);
  const MyComponent = (myDoc) => (
    <div>
        <RichText
            render={myDoc.data.textWithLinks}
            serializeHyperlink={myCustomLink}
        />
    </div>

Passing your own serializer

If serializeHyperlink is not enough, you can alternatively pass an htmlSerializer function. Full example and all accessible elements can be found here. If you need examples or help on this, feel free to open an issue!

Wrapping your rich text in a React component

Out of the box, RichText wraps your content in a React.fragment. But you can pass an optional Component property to RichText component. Re-writing our first example, we could simply pass header to Component:

  const Header = (myDoc) => <RichText render={myDoc.data.title} Component="header" />

Deprecation

In earlier versions of Prismic React, rich text rendering was deferred to a method called render. This method is still accessible, although it doesn't seem to offer any advantage over a React component. If you disagree, please let me know!

example use

 
import { RichText } from 'prismic-reactjs';
 
const Header = (myDoc) => (
    <header>
        {RichText.render(myDoc.data.title)}
    </header>
);

👆 Please note that this method is now a static property of RichText component.
