You can pass custom renderers for nodes and text as optional parameters like so:
import { render, renderNodeRule } from 'datocms-structured-text-to-dom-nodes';
import { isHeading } from 'datocms-structured-text-utils';
const structuredText = {
type: 'root',
children: [
{
type: 'heading',
level: 1,
content: [
{
type: 'span',
value: 'Hello world!',
},
],
},
],
};
const options = {
renderText: (text) => text.replace(/Hello/, 'Howdy'),
customNodeRules: [
renderNodeRule(
isHeading,
({ adapter: { renderNode }, node, children, key }) => {
return renderNode(`h${node.level + 1}`, { key }, children);
},
),
],
customMarkRules: [
renderMarkRule('strong', ({ adapter: { renderNode }, children, key }) => {
return renderNode('b', { key }, children);
}),
],
};
render(document, options);
// -> [<h2>Howdy world!</h2>]
Last, but not least, you can pass custom renderers for itemLink
, inlineItem
, block
as optional parameters like so:
import { render } from 'datocms-structured-text-to-dom-nodes';
const graphqlResponse = {
value: {
schema: 'dast',
document: {
type: 'root',
children: [
{
type: 'paragraph',
children: [
{
type: 'span',
value: 'A ',
},
{
type: 'itemLink',
item: '344312',
children: [
{
type: 'span',
value: 'record hyperlink',
},
],
},
{
type: 'span',
value: ' and an inline record: ',
},
{
type: 'inlineItem',
item: '344312',
},
],
},
{
type: 'block',
item: '812394',
},
],
},
},
blocks: [
{
id: '812394',
image: { url: 'http://www.datocms-assets.com/1312/image.png' },
},
],
links: [{ id: '344312', title: 'Foo', slug: 'foo' }],
};
const options = {
renderBlock({ record, adapter: { renderNode } }) {
return renderNode('figure', {}, renderNode('img', { src: record.url }));
},
renderInlineRecord({ record, adapter: { renderNode } }) {
return renderNode('a', { href: `/blog/${record.slug}` }, record.title);
},
renderLinkToRecord({ record, children, adapter: { renderNode } }) {
return renderNode('a', { href: `/blog/${record.slug}` }, children);
},
};
render(document, options);
// -> [
// <p>A <a href="/blog/foo">record hyperlink</a> and an inline record: <a href="/blog/foo">Foo</a></p>,
// <figure><img src="http://www.datocms-assets.com/1312/image.png" /></figure>
