I do not know anything about this, and an application came up here in the service where I need to get the data from a HTML page, and generate a TXT , or a PDF >, the save will be on the machine itself, because the server is local.
I've been researching a little and I only find information in PHP, where I am not aware of it.
Could anyone help me understand how this manipulation works in HTML/JS ?
If it's in PDF, you can use JSPdf with HTML2Canvas , a simple example of its use.
<div id="div">CONTEUDO</div>
<button id="download">GERAR PDF</button>
let html = document.getElementById('div')
html2canvas(html, {
onrendered: function(canvas) {
let retorno = canvas.toDataURL(
'image/png');
let doc = new jsPDF('p', 'mm');
doc.addImage(retorno, 'PNG', 10, 10);
doc.save('arquivo.pdf');
}
})
