@amarajs/plugin-dom

Plugin middleware for AmaraJS to add HTML to DOM nodes dynamically.

Installation

npm install --save @amarajs/plugin-dom

Usage

// https://github.com/Matt-Esch/virtual-dom
import virtualDom from 'virtual-dom';

import Amara from '@amarajs/core';
import AmaraDOM from '@amarajs/plugin-dom';
import AmaraBrowser from '@amarajs/plugin-engine-browser';
const amara = new Amara([
    AmaraDOM(virtualDom),
    AmaraBrowser()
]);

Feature Type

The @amarajs/plugin-dom middleware allows you to create features of type "dom".

Return Values

For {type: "dom"} features, your apply function should return either an array of virtual DOM nodes or a single root DOM node with optional children.

import h from 'virtual-dom/h';

amara.add({
    type: 'dom',
    targets: ['main'],
    apply: () => [
        h('div', [
            h('p', 'some text'),
            h('p', 'some more text')
        ])
    ]
});

amara.add({
    type: 'dom',
    targets: ['main > div'],
    apply: () => h('p', '... and even more text')
});

Using JSX

You can use JSX instead of creating virtual DOM directly. Simply add the @jsx pragma to the top of your file and use the appropriate configuration for your build process.

For example, the following index.js and rollup.config.js will produce a simple hello world application:

// index.js
/** @jsx h */

import vDOM from 'virtual-dom';
import Amara from '@amarajs/core';
import AmaraDOM from '@amarajs/plugin-dom';
import AmaraBrowser from '@amarajs/plugin-engine-browser';

const h = vDOM.h;

new Amara([
    AmaraBrowser(),
    AmaraDOM(vDOM)
])
    .add({
        type: 'dom',
        targets: ['main'],
        apply: () => (<p>Hello, world!</p>)
    })
    .bootstrap(document.querySelector('body'));

// rollup.config.js
import buble from 'rollup-plugin-buble';
import resolve from 'rollup-plugin-node-resolve';

export default {
    entry: 'index.js',
	useStrict: false,
	plugins: [
        resolve({
            jsnext: true,
            main: true,
            browser: true
        }),
        buble()
    ]
};

Applying Multiple Results to the Same Target

If multiple {type: "dom"} features target the same DOM, the DOM will be appended to the target node in the order the features were applied.

Customization

Construct the @amarajs/plugin-dom instance by providing an instance of VirtualDOM. See https://github.com/Matt-Esch/virtual-dom for details.

Bundled Dependencies

@amarajs/plugin-dom comes bundled with the excellent vdom-parser library to ensure HTML isn't overwritten when applying "dom" features to existing DOM targets.
