Description

This extension provides support for the ReactJS and React Native framework. 

In what situation should you install this extension?

If your Web application contains ReactJS or React Native source code and you want to view these object types and their links with other objects, then you should install this extension:

• creates HTML fragments, ReactJS applications, ReactJS components and ReactJS Forms.
• creates links between these objects.

ReactJS Application

Application name is the file name or the parent directory name if the file name is "index".

Following declarations will create a ReactJS application:

html fragment in ReactDOM.render() call:

import { Provider } from 'react-redux';
import { AppContainer } from 'react-hot-loader';

ReactDOM.render(
  <AppContainer>
    <Provider store={store}>
      <App version={appVersion} />
    </Provider>
  </AppContainer>,
  appElement
);

html fragment containing "Provider" or "AppContainer" tags, in or out of ReactDOM.render() call:

import { AppContainer } from 'react-hot-loader';

<AppContainer>
      <App version={appVersion} />
</AppContainer>

• A relyon link is created from the application to the HTML fragment of the application.

ReactJS Component

This declaration will create a ReactJS component named UserContainer because the class inherits from Component or PureComponent. A component corresponds to a class which contains a render method. The render method is automatically called when the component is refered to in an HTML fragment.

In the function "mapDispatchToProps", there are mapping of functions which are used to find resolutions from HTML fragments to functions. See an example with "deleteUsers" function.

import React, { Component } from 'react';
 
 class UserContainer extends Component {
 
  componentDidUpdate(prevProps) {
...
  }
  componentDidMount = () { ... };

  render() {
    return (
      <g>
        {this.props.sequence.map((nucleotide, index) =>
          <Nucleotide
            type={nucleotide}
            position={this.props.positionFrom + index}
            key={index}
            index={index}
            onClick={this.props.onNucleotideClick}
            {...this.props}
          />,
        )}
      </g>
    );
  }
}

function mapDispatchToProps(dispatch) {
  return {
    createUsers: bindActionCreators(createUsers, dispatch),
    searchUsers: bindActionCreators(searchUsers, dispatch),
    getUsers: bindActionCreators(getUsers, dispatch),
    triggerNotification: bindActionCreators(triggerNotification, dispatch),
    resetUsersActionStatus: bindActionCreators(resetUsersActionStatus, dispatch),
    deleteUsers: bindActionCreators(deleteUsers, dispatch),
    resetSearchUserApiStatus: bindActionCreators(resetSearchUserApiStatus, dispatch),
    getRoles: bindActionCreators(getRoles, dispatch),
    setConfigDetails: bindActionCreators(setConfigDetails, dispatch),
  };
}

function mapStateToProps(state) {
  return {
    loginUsersList: state.admin.loginUsersList,
    imagingUsersList: state.admin.imagingUsersList,
    usersActionStatus: state.admin.usersActionStatus,
    searchUserApiStatus: state.admin.searchUserApiStatus,
    securityMode: state.login.securityMode,
    deleteUserStatus: state.admin.deleteUserStatus,
    rolesList: state.admin.rolesList,
  };
}

export default compose(withStyles(tableStyles), connect(mapStateToProps, mapDispatchToProps))(UserContainer);

• call links are created from the component to its following methods: 'render', 'shouldComponentUpdate', 'componentWillReceiveProps', 'componentWillUpdate', 'componentWillMount', 'componentWillUnmount', 'componentDidUpdate', 'componentDidMount', 'componentDidUnmount'  when they exist.
• these components may be called from html fragments anywhere in code as here:

 <Route
        exact={true}
        path={`${basePath}/apps`}
        component={UserContainer}
      />

or

 <UserContainer ... />

• Functions refered to in the "mapDispatchToProps" function may be referenced anywhere in the code as here:

            <AlertDialog
              onClick={this.deleteUsers}
            />
  
  

ReactJS Function Component

This declaration will create a ReactJS function component named ReportContainer because the function is exported in one of the following statements:

• export default withRouter(connect(mapStateToProps, mapDispatchToProps)(ReportContainer));
• export default connect(null, mapDispatchToProps)(ReportContainer);
• export default connect(mapStateToProps, mapDispatchToProps)(withStyles(stylesTheme)(ReportContainer));
• export default connect(mapStateToProps, mapDispatchToProps)(RedirectIfNotGranted(ReportContainer, 'STORE_ORDER_READ', 'store'));
• export default withStyles(styles)(connect(mapStateToProps, mapDispatchToProps, null, {withRef: true})(ReportContainer));
• export default compose(withStyles(styles), connect(mapStateToProps, mapDispatchToProps))(ReportContainer);
• export default withStyles(styles)(ReportContainer);
• export default compose(withReducer, withSaga, withConnect)(injectIntl(ReportContainer));

File report/img-report-container.jsx

import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';
 
const ReportContainer = (props) => {
  const { isReportDialog, reportList, appName, reportDownloadQueue, reportQueue,
    reportActions, triggerDownload: { nextDownload, activeReportId } } = props;
...
}

function mapStateToProps(state) {
  return {
    isReportDialog: state.report.isReportDialog,
    reportList: state.report.reportList,
    appName: state.dataSource.selectedApp.value,
    reportDownloadQueue: state.report.reportDownloadQueue,
    reportQueue: state.report.reportQueue,
    triggerDownload: state.report.triggerDownload,
  };
}

function mapDispatchToProps(dispatch) {
  return {
    reportActions: bindActionCreators(Object.assign({}, Actions), dispatch),
    triggerNotification: bindActionCreators(triggerNotification, dispatch),
  };
}

export default connect(mapStateToProps, mapDispatchToProps)(ReportContainer);

• A call link is created from the function component to its function.
• these components may be called from html fragments anywhere in code as here:

import ReportDialog from '../report/img-report-container';
...
 <ReportDialog />

• The same is true for "mapDispatchToProps" function as for ReactJS components.

HTML fragment

This declaration will create a HTML fragment named render_fragment_1 starting with "<g>" and ending with "</g>". There can be several fragments in any function/method:

render() {
  return (
    <g>
      {this.props.sequence.map((nucleotide, index) =>
        <Nucleotide
          type={nucleotide}
          position={this.props.positionFrom + index}
          key={index}
          index={index}
          onClick={this.props.onNucleotideClick}
          {...this.props}
        />,
      )}
    </g>
  );
}

When you have purely javascript code inside an html fragment, the javascript code is analyzed and you have links as you would have in conventional javascript code. You may also have javascript functions inside html fragments, in this case, functions are children of the html fragment.
