Tonic is a low profile component framework for the web. It's one file, less than 3kb gzipped and has no dependencies. It's designed to be used with modern Javascript and is compatible with all modern browsers and built on top of Web Components.
Contents
Install
npm i -S @substrate-system/tonic
tl;dr
You can pass full JS objects into components, not just strings, as in HTML.
Use
Bundler
import Tonic from '@substrate-system/tonic'
Pre-bundled
This package exposes minified JS files too. Copy them so they are accessible to your web server, then link to them in HTML.
Copy
cp ./node_modules/@substrate-system/tonic/dist/index.min.js ./public/tonic.min.js
HTML
<script type="module" src="./tonic.min.js"></script>
Examples
You can use functions as components. They can be async or even an async generator function.
async function MyGreeting () {
const data = await (await fetch('https://example.com/data')).text()
return this.html`<h1>Hello, ${data}</h1>`
}
Or you can use classes. Every class must have a render method.
class MyGreeting extends Tonic {
async * render () {
yield this.html`<div>Loading...</div>`
const data = await (await fetch('https://example.com/data')).text()
return this.html`<div>Hello, ${data}.</div>`
}
}
Tonic.add(MyGreeting, 'my-greeting')
After adding your Javascript to your HTML, you can use your component anywhere.
<html>
<head>
<script src="my-greeting.js"></script>
</head>
<body>
<my-greeting></my-greeting>
</body>
</html>

types
See src/index.ts.
tag
Get the HTML tag name given a Tonic class.
static get tag():string;
class ExampleTwo extends Tonic {
render () {
return this.html`<div>example two</div>`
}
}
ExampleTwo.tag
// => 'example-two'
emit
Emit namespaced events, following a naming convention. The return value is the call to element.dispatchEvent().
Given an event name, the dispatched event will be prefixed with the element
name, for example, my-element:event-name.
emit (type:string, detail:string|object|any[] = {}, opts:Partial<{
bubbles:boolean;
cancelable:boolean
}> = {}):boolean
emit example
class EventsExample extends Tonic {
// ...
}
// EventsExample.event('name') will return the namespace event name
const evName = EventsExample.event('testing')
document.body.addEventListener(evName, ev => {
// events bubble by default
console.log(ev.type) // => 'events-example:testing'
console.log(ev.detail) // => 'some data'
})
const el = document.querySelector('events-example')
// use default values for `bubbles = true` and `cancelable = true`
el.emit('testing', 'some data')
// override default values, `bubbles` and `cancelable`
el.emit('more testing', 'some data', {
bubbles: false
cancelable: false
})
static event
Return the namespaced event name given a string.
class {
static event (type:string):string {
return `${this.tag}:${type}`
}
}
example
class EventsExample extends Tonic {
// ...
}
EventsExample.event('testing')
// => 'events-example:testing'
dispatch
Emit a regular, non-namespaced event.
{
dispatch (eventName:string, detail = null):void
}
dispatch example
class EventsExample extends Tonic {
// ...
}
document.body.addEventListener('testing', ev => {
// events bubble by default
console.log(ev.type) // => 'testing'
console.log(ev.detail) // => 'some data'
})
const el = document.querySelector('events-example')
el.dispatch('testing', 'some data')
// override default values
el.dispatch('more testing', 'some data', {
bubbles: false
cancelable: false
})
