Lucia is a tiny JavaScript library for web applications.
Put this within your <head> tags in html.

At the core of Lucia is a system that enables us to declaratively render data to the DOM using straightforward template syntax:
<div id="app">
<p>{{ hello }}</p>
<p>{{ hello === 'world' }}</p>
</div>
const app = new Lucia({
el: '#app',
data: {
hello: 'world',
},
});
// Change data
app.data.hello = 'there';
You can also use the l-html directive for more advanced content manipulation.
<div id="app">
<p l-html="hello"></p>
</div>
const app = new Lucia({
el: '#app',
data: {
hello: '<button>Hello World</button>',
},
});
// Change data
app.data.hello = 'there';
It’s easy to toggle the presence of an element, too:
<div id="app">
<button l-if="show">You can't see me</button>
<button l-if="show === show">Is it equal though?</button>
</div>
const app = new Lucia({
el: '#app',
data: {
show: false,
},
});
To let users interact with your app, we can use the l-on directive to attach event listeners that invoke methods on our Lucia instances:
<div id="app">
<button l-on:click="announce()">{{ message }}</button>
</div>
const app = new Lucia({
el: '#app',
data: {
message: 'Hello world!',
announce() {
alert(this.message);
}
},
});
In addition to text interpolation, we can also bind element attributes like this:
<div id="app">
<h1 l-bind:class="{ hello: show }">Classes are cool</h1>
<h1 l-bind:style="color">Styles are sassy</h1>
</div>
const app = new Lucia({
el: '#app',
data: {
show: true,
// You can also reference data vs inputing an object in the directive itself
color: { color: 'purple' },
},
});
Lucia is MIT Licensed.
