nanoconstruct

Tiny tool to test and develop nanocomponents.

nanoconstruct provides a very simple wrapper around your components and serves them on a simple interface you can access with your browser. It's inspired by Kit and uses budo under the hood.

It includes choo-devtools, so you have access to the state and other Choo things, and tape for testing.

Installation

npm i nanoconstruct

Usage

If your component depends on a custom state or parameters, you can wrap it into a simple wrapper function. Otherwise, a neutral wrapper will be used around the component.

A simple wrapper function looks like this:

var html = require('choo/html')
var Component = require('./components/component')

var c = new Component()

module.exports = () => html`${c.render()}`

Then just point nanoconstruct to the file with:

nanoconstruct example.js

Tests

I want nanoconstruct to provide you with everything you might need to work on a component. So why not tests? You can define a test(t, el) function in your exported wrapper and it'll be ran automatically when you select the component in the app. Check the console!

It gets a tape test object and the rendered element.

var html = require('choo/html')
var Alert = require('./components/alert')

var component = new Alert('Click me!')

module.exports = {
  render: () => html`
    ${component.render(':)')}
  `,
  test: (t, el) => {
    t.plan(1)
    t.equal(el.innerHTML, 'Click me!')
  }
}

Multiple Components

It's also possible to use your whole component library at once. Use the --library mode and point nanoconstruct to a directory of wrapper functions or components.

However, if the structure of your components isn't that simple, export all the wrappers or components from a .js file and use this as input.

Like this:

module.exports = {
  Title: require('./title-wrapper'),
  Content: require('./component/content')
}
