Nuejs-core NPM

Nue JS

Nue JS is a tiny (2.3kb minzipped) JavaScript library for building web interfaces. It is the core layout engine in Nue providing both server-side templating and client-side reactive islands.

"It's just HTML"

Nue uses a simple HTML-based template syntax that you can use for both server-side layouts and reactive, client-side components. For example:

<div class="{ type }">
  <img src="{ img }">
  <aside>
    <h3>{ title }</h3>
    <p :if="desc">{ desc }</p>
    <slot/>
  </aside>
</div>

If React is "just JavaScript", then Nue is "just HTML" because any valid HTML is also valid Nue. You can extend the standard HTML with template expressions that help you build modern websites and web- applications in a simple, declarative way.

Nue is best suited for UX developers dealing with the front of the frontend and with topics like interaction design, accessibility, and user experience.

Class- based

Nue uses ES6 classes to make web development feel more natural and standards-based. Here is an example Nue- component with a submit() instance method:

<form @submit.prevent="submit">
  <input type="email" name="email" placeholder="your@address.com" required>
  <button>Submit</button>

  <script>
    // input validation is natively taken care of by the browser
    async submit({ target }) {
      await fetch(`/api/leads?email=${target.email.value}`)
      location.href = '/thank-you'
    }
  </script>

</form>

The most notable thing is the <script> tag, which is now nested inside the component. This is the place for your ES6 class variables and methods.

ES6 classes make your code look amazingly compact and clean. You can add variables, methods, getters, setters, and async methods with the cute and short syntax. There are no hooks, effects, props, portals, watchers, provides, injects, suspension, or other unusual abstractions on your way. Learn the basics of HTML, CSS, and JavaScript and you are good to go.
