I was able to fix this by adding a blockToHtml
key along with entityToHtml
. I took a clue from #30 (second post). The following code is what works for me :
getInnerHtml() {
return convertToHTML({
styleToHTML: (style) => {
return (
<span
style={
Object.keys(this.customStyleMap).indexOf(style) > -1 ? this.customStyleMap[style] :
style === 'UNDERLINE' ? {textDecoration: 'underline'} :
style === 'BOLD' ? {fontWeight: 'bold'} :
style === 'ITALIC' ? {fontStyle: 'italic'} :
{}
}
/>
);
},
blockToHTML: (block) => {
const type = block.type;
if (type === 'atomic') {
return {start: '<span>', end: '</span>'};
}
if (type === 'unstyled') {
return <p />;
}
return <span/>;
},
entityToHTML: (entity, originalText) => {
if (entity.type === 'IMAGE') {
return `<img src='${entity.data.src}' />`;
}
return originalText;
}
})(this.state.editorState.getCurrentContent());
}
Notice the start
and end
of atomic block types. The styleToHtml
is where I add my custom inline styles.
Hope it helps !

Thanks for following up - I think the built-in default HTML still uses a media
block type - the previous name for atomic
block types. I'll find some time to fix that.
Additionally, I'd recommend for newer versions of draft-js
using block metadata instead of an entity within the atomic block to store information - it makes things a lot more straightforward. See Modifier.setBlockData
and ContentBlock.getBlockData
for more info on usage. For conversion when using that you can then just have a single blockToHTML
function where you can inspect all parts of the block metadata and make a decision on HTML output in one place.

I'm having a similar issue.
In my ContentState I have an atomic block with an entity, which represents an icon. I want it to be rendered as <span class="icon"><i class=${name}></i></span>
.
As far as I understand the documentation it should work like this:
entityToHTML: (entity, originalText) => {
if (entity.type === 'icomoon-icon') {
const { data } = entity
return `<span class='icon'><i class='${data}'></i></span>`
}
return originalText
}
But the entity is contained in an atomic block. And that throws the same error:
Invariant Violation: Expected block HTML value to be non-null
Am I doing something wrong? Do I need a blockToHTML case for the atomic block?

@benbriggs Thanks. I'll fix my editor to use blockData instead of entity within a block.
