Portable Text for Svelte

Use Portable Text with native Svelte components (under development)


Note: this package is in active development, will likely change and may contain errors.


At the moment, it seems the best approach is to install @sanity/block-content-to-hyperscript alongside this component.

Installing Svelte components as a devDependency seems to address this issue.

npm install @movingbrands/svelte-portable-text @sanity/block-content-to-hyperscript --save-dev

Usage example

  import BlockContent from "@movingbrands/svelte-portable-text";
  import Image from "./Image";
  import Link from "./Link";

  export let content;
  export const customSerializers = {
    types: {
      image: props => {
        return {
          component: Image,
          childNodes: props.children,
          props: {
            url: props.node.url
    marks: {
      link: props => {
        return {
          component: Link,
          childNodes: props.children,
          props: props.mark

  <BlockContent blocks={content} serializers={customSerializers} />

Consuming components

With Svelte apps (recommended approach)

This package.json has a "svelte" field pointing to src/index.svelte, which allows Svelte apps to import the source code directly, if they are using a bundler plugin like rollup-plugin-svelte or svelte-loader (where resolve.mainFields in your webpack config includes "svelte").

Apps which aren't using Svelte elsewhere

npm run build will bundle your component's source code into a plain JavaScript module (index.mjs) and a UMD script (index.js).
