Javascript Mustache.js Example to Insert Dynamic Templates to DOM in Browser & Node.js

Welcome folks today in this blog post we will be using the Mustache.js library to insert dynamic templates to DOM in browser using node.js and javascript. All the full source code of the application is shown below.

Get Started

In order to get started you need to make an index.html file and copy paste the following code

index.html

<html>
  <body>
    <form id="form">
      <input type="text" name="" id="name" placeholder="Enter name" required />
      <input type="submit" value="Change Name" />
    </form>
    <div id="target">Loading...</div>
    <script id="template" type="x-tmpl-mustache">
      Hello {{ name }}!
    </script>

    <script src="https://unpkg.com/mustache@latest"></script>
    <script>
      let form = document.getElementById("form");

      form.addEventListener("submit", changeName);

      function changeName(e) {
        e.preventDefault();
        var template = document.getElementById("template").innerHTML;
        var rendered = Mustache.render(template, {
          name: document.getElementById("name").value,
        });
        document.getElementById("target").innerHTML = rendered;
      }
    </script>
  </body>
</html>

<html>

<body>

</form>

<div id="target">Loading...</div>

Hello {{ name }}!

</script>

let form = document.getElementById("form");

form.addEventListener("submit", changeName);

function changeName(e) {

e.preventDefault();

var template = document.getElementById("template").innerHTML;

var rendered = Mustache.render(template, {

name: document.getElementById("name").value,

});

document.getElementById("target").innerHTML = rendered;

}

</script>

</body>

</html>

As you can see we are including the mustache.js library cdn and then we are having the html5 form to allow the user to submit the dynamic username and then we are inserting this name into the html5 template.
