Components from this plugin can be interracted with using hadron-app and hadron-app-registry. Here are a few examples of working with compass-crud's Action and Roles.

Render an editable document in a React component.

const app = require('hadron-app');
const React = require('react');

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.Document = app.appRegistry.getRole('CRUD.Document')[0].component;
  }
  render() {
    return <this.Document doc={this.props.document} editable />;
  }
}

Render a non-editable pre-expanded document in a React component.

const app = require('hadron-app');
const React = require('react');

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.Document = app.appRegistry.getRole('CRUD.Document')[0].component;
  }
  render() {
    return <this.Document doc={this.props.document} expandAll />;
  }
}

Listen to the various CRUD actions.

const app = require('hadron-app');
const CrudActions = app.appRegistry.getAction('CRUD.Actions');

CrudActions.documentRemoved.listen((id) => {
  console.log(`Document with _id ${id} removed.`);
});

CrudActions.openInsertDocumentDialog((doc, clone) => {
  if (clone) {
    console.log('Opening insert dialog with cloned document');
  }
});

CrudActions.insertDocument((doc) => {
  console.log('Inserting document into db');
});

Development

Code Tour

Compass Crud uses React, and Reflux for state management. There are two stores we manage: crud-store(./src/stores/crud-store.js) and grid-store(./src/stores/grid-store.js). Overall structure of this repo:

• ./dist: webpack-compiled version of this plugin.
• ./scripts: scripts to link and unlink React version to compass when developing this locally in Compass.
• ./src/actions: reflux actions that are available throughout this plugin.
• ./src/assets: css assets, such as variables and styles from compass.
• ./src/components: react components that make up this plugin. Almost all components have a .jsx, .spec.js, .less and .js files.
• ./src/stores: home to reflux stores.
• ./src/utils: util .js files to be used throughout the plugin.
