react-mc-template

Render the value we got and modify if we want.

Installation

Using npm:

$ npm install --save react-mc-template

Usage

import React, { useState } from 'react';

import ReactMCTemplate, { Highlight, Core } from 'react-mc-template';

const core = new Core();
const highlight = new Highlight();

/**
 * In this case,
 * will only render some "div" with different id.
 * Because we have not set up options.getComponentClass.
 */
const App = (props = {}) => {
  const [value = {}, setValue] = useState({});
  const [selectedComponent = {}, setSelectedComponent] = useComponent({});

  return (
    <ReactMCTemplate
      core={core}
      highlight={highlight}
      value={value}
      selectedComponent={selectedComponent}
      onChange={setValue}
      onSelectComponent={setSelectedComponent}
    />
  );
};

export default App;

props.value: object

The value you can render.

Detail for value;

props.onChange: func

Trigger it when value was changed.

props.selectedComponent: object

The component you select.

props.onSelectComponent: func

Trigger it when others were selected.

props.document: dom

Set it to iframe.contentDocument you got when render in iframe.

props.body: dom

Set it to iframe.contentDocument.body you got when render in iframe.

props.highlight: object

Highlight when component are selected.

import { Highlight } from 'react-mc-template';

const highlight = new Highlight();

const {
  mask,
  render, // (dom) => {}, run when select component
  clear, // () => {}, run when unmount 
} = highlight;

props.core: object

Convenient operations for value.

import { Core } from 'react-mc-template';

const core = new Core();

const relation = {
  children: ['component-1', 'component-2'],
  list: [
    { content: 'component-3' },
    { content: 'component-4' },
  ],
};

 ['children'],
 ['list', 0, 'content'],

  copyComponent, // (value) => (component) => undefined
  pasteComponent, // (value) => (component) => value
  cutComponent, // (value) => (component) => value
} = core;

props.options: object

The parameters you need to configure to render value in the way you want.

const options = {
  isRoot: (component) => false,
  getComponentClass: (component = {}) => 'div',
  getComponentRenderDependencies: (component = {}) => [],
  getComponentPropsSchema: (component) => ({}),
  getComponentChildrenKeys: (component) => [],
  render: (ComponentClass, component = {}) => (props = {}, ref) => {
    return (
      <ComponentClass ref={ref} {...props} />
    );
  },
};

options.isRoot

Return the boolean means the component is root.If it's root, cannot been moved, copied or deleted.

options.getComponentClass

Return the ComponentClass to render the component.And automatically used react-mc-dnd HOC.If you don't need this, use origin ComponentClass in options.render.

We need ref for ComponentClass to get dom.!!!

import React from 'react';

const Input = React.forwardRef((props, ref) => {
  return 
});

const Text = React.forwardRef((props, ref) => {
  return <span ref={ref} {...props} />
});

const Img = React.forwardRef((props, ref) => {
  return <img ref={ref} {...props} />
});

const getComponentClass = (component = {}) => {
  const { name } = component;

  switch (name) {
    case 'input':
      return Input;
    case 'span':
      return Text;
    case 'img':
      return Img;
    default:
      return 'div';
  }
};

options.getComponentRenderDependencies

Ruturn the dependencies for rendering.The ComponentClass will render only if dependencies change.component, relation, selected and childrenKeys are already in the dependencies by default.

const visibleComponentIds = [];

// render when select the component
const getComponentRenderDependencies = (component = {}) => {
  const { id: componentId } = component;

  const visible = visibleComponentIds.included(componentId);

  return [visible];
};

options.getComponentPropsSchema

We use PropsSchema to define PropTypes. For webpack, you can add a plugin to babel to generate automatically.

Base on JSONSchema

Webpack example

options.getComponentChildrenKeys

The keys in relation we put when we drop something or paste to the component.

/**
 * childrenKeys for div
 *
 * ['children']
 */

options.render

The final touch to render component correctly.This function is useful when you want to do something nasty.

import { findDOMNode } from 'react-dom';

/**
 * ComponentClass: elementType, is what getComponentClass return
 * props: object, base on component.props and relation.
 */
const render = (ComponentClass, component = {}) => (props = {}, ref) => {
  const { current } = ref;
  const dom = findDOMNode(current);

  return (
    <ComponentClass ref={ref} {...props} />
  );
};
