reactive-di-react v1.1.1

reactive-di-react

react bindings for reactive-di

Features:

• Flowtype used for jsx props checking and resolving dependencies.
• React-related code moved from application to reactive-di-react. In application we use only jsx and pure functions.
• Dependencies mixed with props: just declare all them in interface of widget arguments.
• All widgets are statefull and listens only related changes via. reactive-di-observable: virtual dom is unnecessary. You don't need pass dependencies in props from hiorder to underlayer widgets.
• You don't need non-standard type-checking methods like React.PropTypes, use flowtype and babel-plugin-typecheck.
• reactBrowserRenderer helper to less boilerplate code

Define interfaces:

// @flow
// interfaces.js

export type Translate = (message: string) => string;
export type EditTodo = (id: string) => void;

export type TodoItem = {
    id: string;
    title: string;
    isCompleted: boolean;
}

export type TodoItemCollection = Array<TodoItem>;

Define todo element component

Use babel-plugin-react-require to autoimport react. Dependencies mixed with call-time arguments in function options. To separate dependencies use intersection of flow types or magic '@args' comment (see more babel-plugin-transform-metadata).

// @flow
// TodoElement.js
import type {
    TodoItem,
    EditTodo
} from './interfaces'
import type {
    Component,
    Element
} from 'reactive-di-react'

type Props = {
    item: TodoItem;
}

// To support TodoElement properties in flow jsx.
export type ITodoElement = Component<Props>;

type TodoElementProps = Props & {
    t: Translate,
    editTodo: EditTodo
}

export default function TodoElement({
    item,
    t,
    editTodo
}: TodoElementProps): Element {
    return (
        <div>
            <h1>{item.title}</h1>
            <div>
                <a onClick={() => editTodo(item.id)}>{t('edit')}</a>
            </div>
        </div>
    )
}

Define todo element list

All child widgets injects via di:

// @flow
// TodoElementList.js

import type {
    TodoItemCollection
} from 'reactive-di-todomvc/todo'
import type {
    Component,
    Element
} from 'reactive-di-react'
import type {ITodoElement} from './TodoElement'

type TodoElementListProps = {
    TodoElement: ITodoElement;
    data: TodoItemsFacet
};

// Needed for flow support in jsx.
export type ITodoElementList = Component<void>;

export default function TodoElementList({
    data,
    TodoItemCollection
}: TodoElementListProps): Element {
    return (
        <ul className="todo-list">
            {data.items.map((item) => <TodoElement item={item} key={item.id} />)}
        </ul>
    )
}

Setup in reactive-di

// @flow
// main.js
import type {
    Container,
    ConfigItem,
    ContainerManager,
    CreateContainerManager
} from 'reactive-di'

import type {Renderer} from 'reactive-di-react'

import type {ITodoElementList} from './TodoElementList'
import type {ITodoElement} from './TodoElement'

import _ from 'babel-plugin-transform-metadata/_'

import {
    createManagerFactory,
    defaultPlugins,
    createHotRelationUpdater
} from 'reactive-di'

import {observablePlugins} from 'reactive-di-observable'

import {component} from 'reactive-di-react/configurations'
import {
    createReactBrowserRenderer,
    ReactPlugin
} from 'reactive-di-react'

const deps: Array<ConfigItem> = [
    [(_: ITodoElement), component(TodoElement)],
    [(_: ITodoElementList), component(TodoElementList)]    
]

const createContainerManager: CreateContainerManager = createManagerFactory(
    defaultPlugins.concat([ReactPlugin], observablePlugins)
);
const appCm: ContainerManager = createContainerManager(deps);
const di: Container = appCm.createContainer();
const render: Renderer = createReactBrowserRenderer(
    di,
    document.getElementById('app')
);

render((_: ITodoElementList))
