Save HTML locally with Javascript

Question

I do know that Javascript cannot write data in the filesystem, for security reasons. I have often read that the only way to save data locally with Javascript is cookies or <

Answer 1

You can just use the Blob function:

function save() {
  var htmlContent = ["your-content-here"];
  var bl = new Blob(htmlContent, {type: "text/html"});
  var a = document.createElement("a");
  a.href = URL.createObjectURL(bl);
  a.download = "your-download-name-here.html";
  a.hidden = true;
  document.body.appendChild(a);
  a.innerHTML = "something random - nobody will see this, it doesn't matter what you put here";
  a.click();
}

and your file will save.
