In our case, the component we wanted to render was CKEditor5. It’s a tiny and simple WYSIWYG editor.
Its documentation gives the following example on how to render the editor using a static
In our application, we have a React function component:
The goal is to render the
ckeditor component within the
div with id
Can I call the component’s create function in React component?
The first idea that came to my mind was to somehow call the static
create function from
my-ckeditor as DOM element’s id. However, it turns out that we cannot do it directly in the function component before returning, because our div is not loaded into the DOM yet at this moment.
Fortunately, there’s another, easy solution ?
React on DOM element being mounted with useCallback
What we basically want to achieve is to execute the
create static function provided by
ckeditor when our
div is mounted into the DOM.
Let’s first install the ckeditor5 classic editor npm package:
npm i @ckeditor/ckeditor5-build-classic
ckeditor.js file as
Ckeditor in the .tsx file with our component:
const Ckeditor = require('@ckeditor/ckeditor5-build-classic/build/ckeditor.js');
Now, instead of assigning an
id to our
div element, let’s use the
React.useCallback hook and assign it to
Our callback function will be called after our
div component mounts (or unmounts). That’s why we check whether the
node is defined, and then we can do something with that.
This is how it looks in debug mode:
As you can see,
node is defined, and it’s a
div. Exactly the DOM element in which we want to render our
ckeditor component. Let’s now simply change
console.log to rendering the editor as per documentation:
Thanks to that, we can see our editor rendered on the page:
We often use external components in our projects at Yumasoft. In case of above-mentioned
ckeditor, we couldn’t use its React component (because of various reasons) and we had to render it statically using JS function. The solution with
