Intro

Marko is HTML re-imagined as a language for building dynamic and reactive user interfaces.
Just about any valid HTML is valid Marko, but Marko extends the HTML language to allow
building modern applications in a declarative way.

Among these extensions are conditionals, lists, state, and components.
Marko supports both single-file components and components broken into separate files.

Single file component

The following single-file component renders a button and a counter with the
number of times the button has been clicked.

click-count.marko

class {
    onCreate() {
        this.state = { count:0 };
    }
    increment() {
        this.state.count++;
    }
}

style {
    .count {
        color:#09c;
        font-size:3em;
    }
    .example-button {
        font-size:1em;
        padding:0.5em;
    }
}

<div.count>
    ${state.count}
</div>
<button.example-button on-click('increment')>
    Click me!
</button>

Multi-file component

The same component as above split into an index.marko template file,
component.js containing your component logic, and style.css containing your
component style:

index.marko

<div.count>
    ${state.count}
</div>
<button.example-button on-click('increment')>
    Click me!
</button>

component.js

module.exports = {
  onCreate() {
    this.state = { count: 0 };
  },
  increment() {
    this.state.count++;
  }
};

style.css

.count {
  color: #09c;
  font-size: 3em;
}
.example-button {
  font-size: 1em;
  padding: 0.5em;
}

Concise Syntax

Marko also supports a beautifully concise syntax as an alternative to its HTML
syntax. Find out more about the concise syntax here.

<!-- Marko HTML syntax -->
<ul class="example-list">
    <for, color, of=['a', 'b', 'c']>
        <li>${color}</li>
    </for>
</ul>
// Marko concise syntax
ul.example-list
    for, color, of=['a', 'b', 'c']
        li -- ${color}
