    Gatsby Kontent Components

    Gatsby plugin library Stack Overflow

    npm version npm

    The package containing React components useful when processing Kontent data to the site.

    To see the progress of the Gatsby v3 supported packages - check out this pull request.


    npm install @kentico/gatsby-kontent-components gatsby-plugin-image

    Also, add gatsby-plugin-image to plugins array in gatsby-config.js.


    Components exports their typescript definitions so that you know what data format you need to provide via props and what data format expect from function prop callback arguments.

    Image element component

    Images from Kentico Kontent can be displayed using the ImageElement component. This wraps the GatsbyImage component from gatsby-plugin-image, so ensure that you also install that plugin. This component will give the best experience for your users, as it includes responsive srcset, blur-up, lazy loading and many other performance optimizations. Automatic format optimization is always enabled. In many cases it can improve Lighthouse scores by 10-20 points.

    The component takes all the GatsbyImage props, as well as the following properties. All are optional except image:

    Properties of the image object (e.g. width and height) are reflected in Kontent's image API query. Props of the ImageElement component (e.g. width and height) are reflected in the rendered DOM. If the optional props of ImageElement are omitted, the properties of the image object are applied.

    You can find a showcase in the author.js on the development site.

    import React from 'react'
    import { ImageElement } from "@kentico/gatsby-kontent-components"
    import { graphql } from "gatsby";
    export default Page = ({ data }) => {
      const avatar = data.author.elements.avatar_image.value[0];
      return (
    export const query = graphql`
        author: kontentItemAuthor {
          elements {
            avatar_image {
              value {

    Rich text element component

    Rich text elements from Kentico Kontent could be resolved to React components using "html-react-parser" as described in this article.

    This package should make the usage easier. Basically by loading the rich text data and use these components to provide this data and resolution functions.

    Complete showcase could be found in rich-text.js in the development site.

    import { RichTextElement, ImageElement } from "@kentico/gatsby-kontent-components"
    // ...
          resolveImage={image => {
            return (
                alt={image.description ? image.description : image.name}
          resolveLink={(link, domNode) => {
            const parentItemType = contextData.type // It is possible to use external data for resolution
            return (
              <Link to={`/${link.type}/partner/${parentItemType}/${link.url_slug}`}>
          resolveLinkedItem={linkedItem => {
            return <pre>{JSON.stringify(linkedItem, undefined, 2)}</pre>
          resolveDomNode={(domNode, domToReact) => {
            if (domNode.name === "table") {
              // For options - check https://www.npmjs.com/package/html-react-parser#options
              return (
                <div className="table-responsive">

    Resolution scope

    If you don't need to resolve anything, you could just provide value property.


    If you want to resolve images pass images and resolveImage properties.

    • images have to contain at least image_id property
    • resolveImage has one parameter image usually containing one record from images array
    • when resolving images in Rich text element using Image element component, image object must follow data contract defined in Image element component section. Moreover, for correct resolution, the additional image_id identifier of the image is mandatory, as well.

    Links to content items

    If you want to resolve links to other content items pass links and resolveLink properties.

    All other links (web URL, email, asset link) are not resolved. If you could use this functionality, please submit a feature request.

    • links have to contain at least link_id property
    • resolveLink has two parameter link basically containing one record from links array and domNode dome link element that could be used for i.e. getting the inner text of the current link domNode.children[0].data.

    Content components and Linked content items

    If you want to resolve images pass linkedItems and resolveLinkedItem properties.

    • linkedItems have to contain at least system.codename property
    • resolveLinkedItem has one parameter linkedItem basically containing one record from linkedItems array

    Custom resolution for any other dom node

    The general resolution method resolveDomNode is called for every DOM node, except for ones that are resolved specifically (described above). In the example above, all table elements will be wrapped with the div element. You could also return just a JSX if you want to replace the domNode completely.

    If you want to resolve elements via resolveDomNode, you get the following parameters:


    npm i @kentico/gatsby-kontent-components
