// create a JSLRender instance and bind it to the body tag of the page
const view = new JSLRender(document.body);

view.render({
    tag: "h1",
    content: "hello world"
});

JSL-Render also support JSX / TSX Syntax

view.render(<h1>hello world</h1>);

Getting Started

Install

npm install jsl-render

Create a component

In order to create larger applications create "components". A component is any object with a render function that returns a virtual node (ISJLVNode).

import { JSLRender, IJSLComponent } from "jsl-render";

class HelloWorldComponent implements IJSLComponent {

    private counter = 0;

    public render() {
        return {
            tag: "div",
            children: [
                {tag: "button", content: "click", attr: {click: this.increment}},
                {tag: "span", content: "Button was clicked (" + this.counter + ") times"},
            ]
        };
    }

    private increment() {
        this.counter++;
    }

}

const view = new JSLRender(document.body);
view.render(new HelloWorldComponent());

When the button is clicked JSL-Render will automatically refresh the content to display the number of times the button was clicked. The refresh happens because the click handler that updates the counter is bound through the JSL-Render engine.

in case the counter is updated outside of the JSL-Render scope (for example a setTimeout function) refresh has to be executed manually.

import { refresh } from "jsl-render";
refresh();
