JS Toolkit

A JavaScript data-attributes driven micro-framework shipped with plenty of useful utility functions to boost your project.

Installation

Install the latest version via NPM:

npm install @studiometa/js-toolkit

What is it?

This project is a JavaScript micro-framework (along with its utility functions) whose main objectives are:

• Enforcing best-practice and consistency between projects
• Using elements from the DOM easily
• Enabling custom behaviours on component initialization or other user events
• Disabling custom behaviours on component destruction or other user events
• Initializing components in the right place at the right time
• Defining dependencies between components

Quick overview

This framework lets you define components as classes, and bind them to the DOM with data-… attributes. For example, here is how a Counter component would be defined in JavaScript:

import { Base } from '@studiometa/js-toolkit';

export default class Counter extends Base {
  static config = {
    name: 'Counter',
    refs: ['add', 'remove', 'count'],
  };

  get counter() {
    return this.$refs.count.valueAsNumber;
  }

  set counter(value) {
    this.$refs.count.value = value;
  }

  onAddClick() {
    this.counter += 1;
  }

  onRemoveClick() {
    this.counter -= 1;
  }
}

And its accompanying HTML would be sprinkled with data-… attributes to bind elements from the DOM to the JavaScript class.

<div data-component="Counter">
  <button data-ref="add">Add</button>
  <button data-ref="remove">Remove</button>
  <input data-ref="count" type="number" value="0" />
</div>

You can define options that can be specified with data-option-... attributes as well. First in JavaScript:

  class Counter extends Base {
    static config = {
      name: 'Counter',
      refs: ['add', 'remove', 'count'],
+     options: {
+       step: {
+         type: Number,
+         default: 1,
+       },
+     },
    };

    onAddClick() {
-     this.counter += 1;
+     this.counter += this.$options.step;
    }

    onRemoveClick() {
-     this.counter -= 1;
+     this.counter -= this.$options.step;
    }
  }

And then adjust it as you wish in your HTML:

- <div data-component="Counter">
+ <div data-component="Counter" data-option-step="2">
    <button data-ref="add">Add</button>
    <button data-ref="remove">Remove</button>
    <input data-ref="count" type="number" value="0">
  </div>

The framework also offers a way to instantiate a root component as an application, with child components as dependencies:

import { Base, createApp } from '@studiometa/js-toolkit';
import Counter from './components/Counter.js';

class App extends Base {
  static config = {
    name: 'App',
    components: {
      Counter,
    },
  };
}

export default createApp(App);
