Intro
Marko is HTML reimagined as a language for building dynamic and reactive user interfaces. Almost any valid HTML is valid Marko, and Marko extends HTML for building modern applications more declaratively. Among these extensions are conditionals and lists, state, and components.
Marko supports both single-file components and components across separate files.
Single-file component
The following renders a button and a counter of how many times the button has been pressed:
click-count.marko
class {
onCreate() {
this.state = { count: 0 };
}
increment() {
this.state.count++;
}
}
style {
.count {
color: #09c;
font-size: 3em;
}
.press-me {
padding: 0.5em;
}
}
<output.count>
${state.count}
</output>
<button.press-me on-click('increment')>
Press me!
</button>Multi-file component
The same component as above, but split into:
index.markotemplate filecomponent.jscomponent JS logic filestyle.csscomponent styles file
index.marko
<output.count>
${state.count}
</output>
<button.press-me on-click('increment')>
Press me!
</button>component.js
export default {
onCreate() {
this.state = { count: 0 };
},
increment() {
this.state.count++;
},
};style.css
.count {
color: #09c;
font-size: 3em;
}
.press-me {
padding: 0.5em;
}Concise Syntax
Marko also supports a beautifully concise syntax as an alternative to its HTML syntax:
| Concise syntax | HTML syntax |
|---|---|
ul.example-list
for|color| of=[a, b, c]
li -- ${color} |
<ul class="example-list">
<for|color| of=[a, b, c]>
<li>${color}</li>
</for>
</ul> |
