Ogone

Description

use Ogone to compile web-components for your applications. it’s based on Deno. Actually Ogone is under an experimental phase. avoid using it for production. Ogone has it own extension *.o3 which allow some new features. No Proxies, no getters, no setters used for the reactivity, just code…

Installation

import o3 from 'https://x.nest.land/Ogone@0.16.0-rc.3/mod.ts';

o3.run({
  entrypoint: 'path/to/root-component.o3',
  modules: '/modules',
  port: 8080,
});

Usage

After the first example, in your root-component.o3, you can make this first greeting app

<proto>
  def:
    name: SRNV
</proto>
<p>Hello ${name}</p>

let’s change the name after 1 second.

<proto>
  def:
    name: SRNV
  default:
    setTimeout(() => {
      this.name = 'World';
    }, 1000);
  break;
</proto>
<p>Hello ${name}</p>

this will only update the textnode containing ‘Hello ${name}’ and replace name by it’s value. You certainly recognized the default expression of a switch statement.

so now what is proto def ?

Making the choice to use only the switch statement to rule the code, includes that the wordings has to be clear enough to understand what is going on.

instead of using script tag, I choosed to use proto tag which is a custom element. the fact is, when we define the Ogone components we are not building a module js. you wont be able to use inside <proto> the import statements. we will see after how to import modules inside your component.

at this point, it means Ogone has to read something that is not conventionnal. It’s all new to code component only in a switch statement.

ok but def ?!

def means ‘definition’ or ‘define’ (like Python), this custom statement let you define the data of your component. def is the area that only supports YAML language

output

Ogone will wrap your code into a tiny function which takes 3 arguments. the state of the component, the context of the function and an event (Event | undefined)

(function (_state, ctx, event) {
  switch (_state) {
    ${yourCode}
  }
});

why in a switch statement ?

Switch statement provides an out of the box well structured code. it’s globally readable and understood by all. And Ogone is follwing a minimalistic philosophy. using few options/expressions to structure the code is a good way to make it clear, readable, radically clean.

Expressions and Custom Expressions

Following this structure of declarations is strongly recommanded:

def* (YAML)
before-each* (for global declarations)
case
default

*only supported by Ogone

Some examples/

Async component example

read this documentation on Async Components.

// require statement tells to the parent component what is needed inside the component.
require id as Number;
// use statement tells to Ogone to use the file as store-component
use @/examples/tests/async/reloading/store.o3 as 'store-component';

<store-component namespace="user"/>
<proto type="async">
  def:
    user: null
  before-each: // 0.6.0
    const getUser = () => Store.dispatch('user/getUser', this.id)
        .then((user) => {
          this.user = user;
          return user;
        });
  case 'async:update':
    getUser();
  break;
  default:
    getUser().then(user => Async.resolve(user));
</proto>

<div> Welcome ${user ? user.username : ''}</div>
<img src="public/ogone.svg"  --await />

let’s see what we can do inside the parent component

use @/examples/tests/async/reloading/async.o3 as 'async-component';
use @/examples/tests/async/reloading/store.o3 as 'store-component';

<store-component namespace="user" />
<async-component :id="id" --await --then:user-loaded />
<proto type="async">
  def:
    id: 1
  case 'then:user-loaded':
    Store.commit('user/USER-IS-LOADED', ctx)
      .then(() => {
        Async.resolve();
      });
    break;
</proto>

Reflected datas

read the docs on reflected datas

<proto>
  def:
    name: SRNV
    fullname: ''
  before-each:
    this.fullname => this.name + Math.random();
  default:
    setTimeout(() => {
      this.name = 'Rudy';
    }, 1000);
  break;
</proto>
<p>Hello ${fullname}</p>

recursive component example

require item as Object

use @/examples/app/components/menu/tree-recursive-button.o3 as 'tree-recursive'
use @/examples/app/components/scroll.o3 as 'scroll'

<proto>
  def:
    openTree: false
  case 'click:toggle':
    this.openTree = !this.openTree
  break;
</proto>

<div class="container">
  <div class="title" --click:toggle --router-go="item.route">
    <span>
     ${item.name}
    </span>
    <span --class="!item.children && item.status ? `status ${item.status}` : ''">
      ${!item.children && item.status ? item.status : ''}
    </span>
    <span --if="item.children && !openTree"> > </span>
    <span --else-if="item.children && openTree"> < </span>
  </div>
  <div class="child" --if="item.children" --class="{ 'child-open': openTree }">
    <scroll>
      <tree-recursive
        --if="!!item.children"
        --for="item.children as (child)"
        :item="child ? child : {}"></tree-recursive>
    </scroll>
  </div>
</div>

Theory

Minimalist:

the less is more.
Every solutions have a minimalist alternative solution (cleaner, scalable).
what you wrote twice, you have to write it once.
no useless code has to be compiled.
everything is a component, because everything is a part of a composition.

All in one. including:

Store
Router
Controllers for Stubs
Tests
- unit tests
- Integrations tests
- e2e
HMR
