@wallerbuilt/mycelia v1.1.0

mycelia

A minimal, DOM manipulation library with Javascript functions as elements and a universal dispatching system

This is a continuation/improvement/evolution from mantle

Installation

npm i -S @wallerbuilt/mycelia

Basic Usage

import { mount, dom } from "@wallerbuilt/mycelia";

// Main element to mount the mycelia app to
const appSelector = "#app"

// abstracting the div and h1 element from dom object (could also use it as `dom.div` and `dom.h1`)
const { div, h1 } = dom;

const Heading = h1({ classname: 'intro-heading' }, "Hello mycelia!");

// Children are an array of mycelia elements or non-array strings
const App = div({ classname: 'app-container' }, [Heading])

// mount our App to appSelector element
mount(App, appSelector);

Elements

Elements are created from the dom object.

import { dom } from "@wallerbuilt/mycelia";

const { div, button, p } = dom;

const Item = div({ className: "item" }, [
	p("I have some interesting things to say in this item's paragraph."),
	button({ onclick: console.log }, "Click me!")
]);

Mount

mount is the jumping off point of your application and typically takes the outermost element as an argument.

import { mount, dom } from "@wallerbuilt/mycelia";

const appSelector = "#app";

const App = dom.div("the app here")

mount(App, appSelector);

Events and Dispatch

import { Emitter } from "@wallerbuilt/mycelia";

type State = {
  todos: string[];
}

const emit = new Emitter<State>(); // the generic is then passed to `on` and `dispatch` on instantiation

When using emit.on or emit.dispatch, your payload returned and sent (respectively), requires that type of state object to be passed.

emit.on("event:name")(({ todos }) => console.log(todos));

emit.dispatch("event:name")({ todos: ["one added"] });
