cherry-on-lit v1.0.1

cherry-on-lit

This package offers a mixin (CherryOnLit) you can use to aggregate elements with an id attribute in your LitElement template.

Usage

import { LitElement, html } from 'lit-element';
import { CherryOnLit } from 'cherry-on-lit';

class MyApp extends CherryOnLit(LitElement) {
  render () {
    return html`
    <div id="myElement">loading</div>
    `
  }

  firstUpdate() {
    this.$.myElement.innerText = 'hello anonymous';
  }
}

(it also works with typescript)

Installation

npm install cherry-on-lit

Notes

Pros:

• It's easy to install
• You don't need to write all the query functions.

Cons:

• Everytime you request $ it scan the dom, it may affect the performance of your code if your template is massive and you overuse it.
• Your IDE will lose track of the typings because the $ aggregator is naively querying the elements in the dom without any cast. For this reason I recommand using typescript and casting the elements as you request them:

const i = this.$.importantInput as HTMLInputElement;
i.value = 'new value';
