What methods should I use to sanitize inputs for a MERN application

I'm creating a MERN application and normally I would think about SQL injection but I was wondering what should be done for node/mongoDB and if there is something React has that could help with anything that needs to be done to protect inputs.

The application has registration and a user profile, social media structure.

I am also using CKEditor to allow people to save the text formatting for their posts.

But when I display this I am currently using dangerouslySetInnerHTML={{ __html: viewPost.entry }} in the React frontend.

Is there a way to sanitize this going in with CKEditor or a different way to display it without using dangerouslySetInnerHTML?

<CKEditor
            editor={ClassicEditor}
            data=''
            value={entry}
            onInit={(editor) => {
              // You can store the "editor" and use when it is needed.
              // console.log("Editor is ready to use!", editor);
              editor.editing.view.change((writer) => {
                writer.setStyle(
                  'height',
                  '500px',
                  editor.editing.view.document.getRoot()
                );
              });
            }}
            onReady={(editor) => {
              // You can store the "editor" and use when it is needed.
              console.log('Editor is ready to use!', editor);
            }}
            onChange={(event, editor) => onChangeInEditor(event, editor)}
            onBlur={(event, editor) => {
              console.log('Blur.', editor);
            }}
            onFocus={(event, editor) => {
              console.log('Focus.', editor);
            }}
          />
