## 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](https://markojs.com/docs/conditionals-and-lists/), [state](https://markojs.com/docs/state/), and [components](https://markojs.com/docs/class-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**
|
|
|
|
```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.marko` template file
|
|
- `component.js` component JS logic file
|
|
- `style.css` component styles file
|
|
|
|
**index.marko**
|
|
|
|
```marko
|
|
<output.count>
|
|
${state.count}
|
|
</output>
|
|
<button.press-me on-click('increment')>
|
|
Press me!
|
|
</button>
|
|
```
|
|
|
|
**component.js**
|
|
|
|
```js
|
|
export default {
|
|
onCreate() {
|
|
this.state = { count: 0 };
|
|
},
|
|
increment() {
|
|
this.state.count++;
|
|
},
|
|
};
|
|
```
|
|
|
|
**style.css**
|
|
|
|
```css
|
|
.count {
|
|
color: #09c;
|
|
font-size: 3em;
|
|
}
|
|
.press-me {
|
|
padding: 0.5em;
|
|
}
|
|
```
|
|
|
|
## Concise Syntax
|
|
|
|
Marko also supports [a beautifully concise syntax as an alternative](https://markojs.com/docs/concise/) to its HTML syntax:
