HTML template strings for the Browser with support for Server Side Rendering in Node.

Installation

$ npm install nanohtml

Usage

Browser

var html = require('nanohtml')

var el = html`
  <body>
    <h1>Hello planet</h1>
  </body>
`

document.body.appendChild(el)

Node

Node doesn't have a DOM available. So in order to render HTML we use string concatenation instead. This has the fun benefit of being quite efficient, which in turn means it's great for server rendering!

var html = require('nanohtml')

var el = html`
  <body>
    <h1>Hello planet</h1>
  </body>
`

console.log(el.toString())

Interpolating unescaped HTML

By default all content inside template strings is escaped. This is great for strings, but not ideal if you want to insert HTML that's been returned from another function (for example: a markdown renderer). Use nanohtml/raw for to interpolate HTML directly.

var raw = require('nanohtml/raw')
var html = require('nanohtml')

var string = '<h1>This a regular string.</h1>'
var el = html`
  <body>
    ${raw(string)}
  </body>
`

document.body.appendChild(el)

Attaching event listeners

var html = require('nanohtml')

var el = html`
  <body>
    <button onclick=${onclick}>
      Click Me
    </button>
  </body>
`

document.body.appendChild(el)

function onclick (e) {
  console.log(`${e.target} was clicked`)
}

Static optimizations

Parsing HTML has significant overhead. Being able to parse HTML statically, ahead of time can speed up rendering to be about twice as fast.

Browserify

From the command line

$ browserify -t nanohtml index.js > bundle.js

Programmatically

var browserify = require('browserify')
var nanohtml = require('nanohtml')
var path = require('path')

var b = browserify(path.join(__dirname, 'index.js'))
  .transform(nanohtml)

b.bundle().pipe(process.stdout)

In package.json

{
  "name": "my-app",
  "private": true,
  "browserify": {
    "transform": [
      "nanohtml"
    ]
  },
  "dependencies": {
    "nanohtml": "^1.0.0"
  }
}

Webpack

At the time of writing there's no Webpack loader yet. We'd love a contribution!

Babel / Parcel

Add nanohtml to your .babelrc config.

Without options:

{
  "plugins": [
    "nanohtml"
  ]
}

With options:

{
  "plugins": [
    ["nanohtml", {
      "useImport": true
    }]
  ]
}

Options

  • useImport - Set to true to use import statements for injected modules. By default, require is used. Enable this if you're using Rollup.
  • appendChildModule - Import path to a module that contains an appendChild function. Defaults to "nanohtml/lib/append-child".
