Is it possible to save textinput (locally) from a form to a textfile, and then open that document to use it later on?
Just using HTML, javascript and jQuery. No databases or php.

There is a built-in Module or in-built library in NodeJs which handles all the writing operations called fs (File-System). It is basically a JavaScript program (fs. js) where function for writing operations is written. Import fs-module in the program and use functions to write text to files in the system.
It's possible to save only if the user allow it to be saved just like a download and he must open it manually, the only issue is to suggest a name, my sample code will suggest a name only for Google Chome and only if you use a link instead of button because of the download attribute.
You will only need a base64 encode library and JQuery to easy things.
// This will generate the text file content based on the form data
function buildData(){
var txtData = "Name: "+$("#nameField").val()+
"\r\nLast Name: "+$("#lastNameField").val()+
"\r\nGender: "+($("#genderMale").is(":checked")?"Male":"Female");
return txtData;
}
// This will be executed when the document is ready
$(function(){
// This will act when the submit BUTTON is clicked
$("#formToSave").submit(function(event){
event.preventDefault();
var txtData = buildData();
window.location.href="data:application/octet-stream;base64,"+Base64.encode(txtData);
});
// This will act when the submit LINK is clicked
$("#submitLink").click(function(event){
var txtData = buildData();
$(this).attr('download','sugguestedName.txt')
.attr('href',"data:application/octet-stream;base64,"+Base64.encode(txtData));
});
