Create a document using a file

const Document = require('node-html-light').Document
const resolve = require('path').resolve

Document.fromPath(resolve('./index.html')).then((document) => {
    // head is an instance of Node
    const head = document.head()
    // body is an instance of Node
    const body = document.body()

    // find child elements
    // append child elements
    // remove child elements
    // replace child elements

    return document.toHtml()
}).then((html) => {
    // ..
})

Create a Node using a File

const Node = require('node-html-light').Node
const resolve = require('path').resolve

Node.fromPath(resolve('partial.html')).then((node) => {})

Create a Node using a String

const Node = require('node-html-light').Node

const node = Node.fromString('<div></div>')

Create a Node with raw data

const Node = require('node-html-light').Node
const Attributes = require('node-html-light').Attributes

const node = Node.of('meta', Attributes.of({
        'name': 'viewport',
        'theme-color': '#795548'
    })
)

Find a child Node of an existing Element

const Node = require('node-html-light').Node
const Attributes = require('node-html-light').Attributes
const resolve = require('path').resolve

Node.fromPath(resolve('partial.html')).then((node) => {
    const content = node.find('div', Attributes.of({
        'name': 'viewport',
        'theme-color': '#795548'
    }))
})
