TODO

IMPLEMENT

- @heleonix/testing wrapped mocks, auto deep mocks, auto shallow mocks, manual mocks
    ○ @heleonix/testing-jasmine
    ○ @heleonix/testing-jest
- Store full path to each view being rendered in the presenter and pass it to an exception if any
- Review all implementation and implement validation functions which throw exceptions for all components and all cases
- Use Object.is to compare values in setters of data, property, state decorators

CONTEXT

Context is an object with string values, which splits resources of applications:

{
    "env": "dev",
    "customer": "customer1",
    "culture": "uk-UK"
}

In webpack plugins context is specified as below:

[
    // Least specific
    {
        "name": "env",
        "values": ["dev", "test", "prod"],
    },
    {
        "name": "customer",
        "values": ["customer1", "customer2", "customer3"],
    },
    {
        "name": "culture",
        "values": ["en-US", "uk-UK"],
    },
    // Most specific
];

Context-specific files are named in format:

MyFile.ext MyFile.uk-UK.customer1.dev.ext MyFile.uk-UK.ext MyFile.dev.ext MyFile.customer1.ext

DICTIONARIES (MERGEABLE)

Buttons.en-US.dic Buttons.en-US.customer1.dic Buttons.es-ES.customer1.dic

Buttons.test.customer2.en-US.dic:

<Dictionary>
    <Add>Add</Add>
    <Remove>Remove</Remove>
    <Ok>OK {usertitle}</Ok>
    <!--for this message you must provide params: username, usertitle-->
    <OkOrCancel>
        Hi {username}! Are you {.Ok} or {@BaseControls.Cancel}?
    </OkOrCancel>
</Dictionary>

Compiled into:

{
    "name": "Buttons",
    "context": {
        "env": "test",
        "customer": "customer1",
        "culture": "en-US"
    },
    "items": {
        "Add": "Add",
        "Remove": "Remove",
        "Ok": "OK {usertitle}",
        "OkOrCancel": "Hi {username}! Are you {.Ok} or {#BaseControls.Cancel}?"
    }
}

Have methods:

setup(definition), like controls
getValue(key, args)

SETTINGS (MERGEABLE)

Key/Value pairs like dictionaries but with values of any JSON type and they cannot have replacement parameters and references to other keys or settings.

STYLES (MERGEABLE, EXTENDABLE)

Style is applied as class="auto generated classes" to the root native html elements only, i.e.:

<div class="auto generated classes">
	<button />
	<button />
	<button />
</div>

<li class="auto generated classes">one</li>
<li class="auto generated classes">two</li>
<li class="auto generated classes">three</li>

MyView.style MyView.customer1.style MyView.en-US.customer1.style

MyView.style:

<Style extends="MyBaseView">
	<border-color value="#aaa" />
  <width>
	<color>
    <!-- Think about conditional setting -->
  </color>
</Style>

Compiled into:

{
	"extends": "MyBaseView",
	"items": {
		"border-color": "#aaa";
		"color": "vm => vm.isValid ? 'green' : 'red'"
	}
}

SERVICES

Can inject another services.

HttpService - provides many scenarios with requests:

sequential requests
parallel requests
polling with intervals and specified number of retries
optimistic updates with pending statuses
etc
Returns an empty object with internal promise, so it can be bound to a view, so when promise is resolved, the empty object is populated with data and model is updated and view is refreshed.

CONVERTERS

classes with "format", "parse", getDictionary(dictionaryName, keyName, ...args), getSetting(...) functions.

TASKS

have "run" function and any number of properties. have getSetting(settingName, settingKey) function. Can inject services.

PROVIDERS

Provide dictionary definitions, control definitions, style definitions, theme definitions, settings definitions. Can inject services. have getSetting(settingName, settingKey) function.

index.html -> <div id="root"></div>

index.js -> new MyApplication().run()
