Examples

Marko provides an elegant and readable syntax for both single-file components and components broken into separate files. There are plenty of examples to play with on Marko's Try-Online. Additional component documentation can be found on the Marko.js website.

Single file

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

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

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 support a beautiful concise syntax as an alternative to the HTML syntax. Find out more about the concise syntax here.

<!-- Marko HTML syntax -->
<ul>
    <li for(color in ['a', 'b', 'c'])>
        ${color}
    </li>
</ul>

// Marko concise syntax
ul
    li for(color in ['a', 'b', 'c'])
        -- ${color}
