Customized Gutenberg block: entry dom factor through JavaScript

I am creating a customized Gutenberg block and want to use the identical JavaScript code on frontend and backend.

Within the save perform of the block I generate the next html code (abridged):

return (
    <div {...blockProps}>
        <desk className="my-plugin-table" data-rows="50">
            <thead>
                <th>Col 1</th>
                <th>Col 2</th>
            </thead>
        </desk>
    </div>
)

The frontend code reads the info attribute and creates the tbody factor with 50 rows which might be fetched from an API through fetch(), like so:

const tables = doc.querySelectorAll('.my-plugin-table')
tables.forEach(desk => {
    const tbody = doc.createElement('tbody')
    desk.appendChild(tbody)
    const rows = desk.dataset.row
    const apiURL = 'https://xxxxxxx?rows=" + rows
    fetch(apiRUL)
        .then(response => response.json())
        .then(knowledge => {
            const trs = []
            knowledge.parts.forEach(factor => {
                const tr = doc.createElement("tr')
                const td1 = doc.createElement('td')
                const td2 = doc.createElement('td')
                td1.innerHTML = factor.key
                td2.innerHTML = factor.label
                tr.replaceChildren(td1, td2)
                trs.push(tr)
            })
            tbody.replaceChildren(trs)
        })
})

Within the edit perform of the block I exploit the equivalent html code:

return (
    <div {...blockProps}>
        <desk className="my-plugin-table" data-rows="50">
            <thead>
                <th>Col 1</th>
                <th>Col 2</th>
            </thead>
        </desk>
    </div>
)

What’s the greatest observe right here to make use of the frontend JavaScript within the backend as nicely? I have to entry the dom factor contained in the editor. I attempted it with wp.knowledge.choose( 'core/block-editor' ).getBlocks() however to no avail.

Are you able to possibly give me a touch what can be the perfect resolution within the Gutenberg and WordPress manner?
