Users of the extension providing ReactJS support for Web applications.

Summary: This document provides information about the extension providing ReactJS support for Web applications.

What's new

  • Initial version

Description

This extension provides support for the ReactJS framework.

In what situation should you install this extension?

If your Web application contains ReactJS 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 Javascript Front-end connected to Node.js/Express/MongoDB Back-end

ReactJS Application

This declaration will create a ReactJS application named App:

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

ReactJS Component

This declaration will create a ReactJS component named Sequence because the class inherits from Component. 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:

import React, { Component } from 'react';
 
 class Sequence extends Component {
 
  shouldComponentUpdate(nextProps) {
    return this.props.positionFrom !== nextProps.positionFrom ||
      this.props.sequence !== nextProps.sequence ||
      this.props.nucleotidesPerRow !== nextProps.nucleotidesPerRow ||
      this.props.rowHeight !== nextProps.rowHeight;
  }
 
  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>
    );
  }
}

ReactJS Form

This declaration will create a ReactJS form named contact:

import React from 'react'
import { Field, reduxForm } from 'redux-form'

let ContactForm = props => {
  const { handleSubmit } = props
  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="firstName">First Name</label>
        <Field name="firstName" component="input" type="text" />
      </div>
      <div>
        <label htmlFor="lastName">Last Name</label>
        <Field name="lastName" component="input" type="text" />
      </div>
      <div>
        <label htmlFor="email">Email</label>
        <Field name="email" component="input" type="email" />
      </div>
      <button type="submit">Submit</button>
    </form>
  )
}

ContactForm = reduxForm({
  // a unique name for the form
  form: 'contact'
})(ContactForm)

export default ContactFormrender() {
  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>
  );
}

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>
  );
}

In the code example for the ReactJS application, we can see that it contains also a HTML fragment.

Icon(s)FileExtensionNotes

HTML

*.html, *.htm, *.xhtml
  • creates one "HTML5 Source Code" object that is the caller of html to js links and a transaction entry point
  • broadcasts tags and attributes/values to other CAST extensions such as AngularJS. Other extensions will not need to analyze the files themselves.

Javascript*.js
  • creates Functions, Classes and Constructors
  • local call links between function calls and functions inside each JavaScript file.

Cascading Style Sheet*.css
  • No specifc objects are created

Java Server Page*.jsp


JSX*.jsx

Active Server Page*.asp, *.aspx


HTML Components*.htcHTC files contain html, javascript fragments that will be parsed. Created objects will be linked to the HTC file.

.NET Razor*.cshtml


Function Point, Quality and Sizing support

This extension provides the following support:

  • Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
  • Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

Dependencies with other extensions

Some CAST extensions require the presence of other CAST extensions in order to function correctly. The ReactJS extension requires that the following other CAST extensions are also installed:

Note that when using the CAST Extension Downloader to download the extension and the Manage Extensions interface in CAST Server Manager to install the extension, any dependent extensions are automatically downloaded and installed for you. You do not need to do anything.

Download and installation instructions

Please see:

The latest release status of this extension can be seen when downloading it from the CAST Extend server.

Packaging, delivering and analyzing your source code

Once the extension is downloaded and installed, you can nowpackage your source code and run an analysis. The process of packaging, delivering and analyzing your source code is described below:

Packaging and delivery

Note that the ReactJS extension does not contain any CAST Delivery Manager Tool discoverers or extractors, therefore, no "ReactJS" projects will be detected. However, the Web Files Discoverer extension will be automatically installed (it is a "shipped" extension which means it is delivered with AIP Core) and will automatically detect projects as HTML5 if specific files are delivered, therefore ensuring that Analysis Units are created for your source code.

Using AIP Console

Using CAST Management Studio

 Click here to expand...
  • create a new Version
  • create a new Package for your ReactJS source code using the Files on your file system option:

  • Define the root folder of your Application source code:

  • Run the Package action
  • Before delivering the source code, check the packaging results:
Without the Web Files Discover

If you are not using the Web Files Discoverer, the following will occur:

  • the CAST Delivery Manager Tool will not find any "projects" related to the ReactJS application source code - this is the expected behaviour. However, if your ReactJS related source code is part of a larger application (for example a JEE application), then other projects may be found during the package action (click to enlarge):

With the Web Files Discoverer

If you are using the Web Files Discoverer, the following will occur:

  • the CAST Delivery Manager Tool will automatically detect "HTML5 file projects" (see Web Files Discoverer for more technical information about how the discoverer works) related to the ReactJS application source code. In addition, if your ReactJS related source code is part of a larger application (for example a JEE application), then other projects may also be found during the package action (click to enlarge):

  • Deliver the Version

Analyzing

Using AIP Console

AIP Console exposes the technology configuration options once a version has been accepted/imported, or an analysis has been run. Click Universal Technology (3) in the Config (1) > Analysis (2) tab to display the available options for your ReactJS source code:

Then choose the relevant Analysis Unit (1) to view the configuration:

Using the CAST Management Studio

 Click here to expand...
  • Accept and deploy the Version in the CAST Management Studio.
Without the Web Files Discover

If you are not using the Web Files Discoverer, the following will occur:

  • No Analysis Units will be created automatically relating to the ReactJS source code - this is the expected behaviour. However, if your ReactJS related source code is part of a larger application (for example a JEE application), then other Analysis Units may be created automatically:

  • In the Current Version tab, add a new Analysis Unit specifically for your ReactJS source code, selecting the Add new Universal Analysis Unit option:

  • Edit the new Analysis Unit and configure in the Source Settings tab:
    • a name for the Analysis Unit
    • ensure you tick the HTML5/JavaScript option (the ReactJS extension depends on the HTML5 and JavaScript extension - and therefore the Universal Analyzer language for the AngularJS extension is set as HTML5/JavaScript)
    • define the location of the deployed ReactJS source code (the CAST Management Studio will locate this automatically in the Deployment folder):

  • Run a test analysis on the Analysis Unit before you generate a new snapshot.
With the Web Files Discoverer

If you are using the Web Files Discoverer, the following will occur:

  • "HTML5" Analysis Units will be created automatically (see Web Files Discoverer for more technical information about how the discoverer works) related to the ReactJS application source code. In addition, if your ReactJS related source code is part of a larger application (for example a JEE application), then other Analysis Units may also be created:

  • There is nothing further to do, you can now run a test analysis on the Analysis Unit before you generate a new snapshot.

What results can you expect?

Once the analysis/snapshot generation has completed, you can view the results in the normal manner:

Objects

The following objects are identified:

IconMetamodel name

ReactJS Application

ReactJS Component

ReactJS Form

HTML5 HTML fragment

Links from the ReactJS application

  • A relyon link is created from the application to the HTML fragment of the application.
  • A call link is created from the fragment to the ReactJS component refered to in the fragment
  • A call link is created from the component to the render method of the class representing the component (as render method is automatically called).
  • A call link is created from the render method to the fragment comtained inside the render method

Please remember that components are called mainly from html fragments, and render methods are implicitly called from ReactJS components.

Links from a HTML fragment

Many links are created from fragments, for example:

Click to enlarge:

HTML tags present in HTML fragments are linked to ReactJS components if they exist, or else a JavaScript function:

Click to enlarge:

HTML atribute values present in HTML fragments are linked to methods when they are represented between { ... }:

Click to enlarge:

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.
