SRBInfoAndSupportJS

Motivation

Our product installations are slowly piling up and support is becoming increasingly difficult. It is of course important for us to be able to identify errors quickly, simplify analyzes and be able to react quickly to problems.

For this reason I developed the JS Library SRBInfoAndSupport.js. This gives us the opportunity to evaluate important information quickly and easily.

The most important information for error identification includes:

• Browser designation ( version )
• Screen size
• URL of the application ( incl. port, hostname, path )
• Device Zoom
• Version of our product (last Git commit)
• What data is in the local storage
• Screenshot of the application
• ...

The most common application of the library will probably be to display a button that shows the user the important information mentioned above. This is very easy to do with the Lib. Simply integrate it into the project and a dialog is presented to the user with the following function call:

SRBInfoAndSupport.showSupportDialog("My dialog title", {​​
   captureScreenshot: true,
}​​);

This call results in:

As can be seen in the screenshot, the users/developers now have the option of sending the data via email or copying it to the clipboard.

Furthermore, it is mandatory for legal reasons to display licenses. Both our product licenses and licenses for the libraries we use (open source libs etc.)

This is also covered by SRBInfoAndSupport.js. Using the following function call...

SRBInfoAndSupport.showOverviewDialog("Title");

...a dialog is generated that displays all important information:

Important technical background:

All displayed fixed data is loaded dynamically from configuration files. This has a significant advantage when making the library dynamic. For example, in the case of licenses, a JSON file containing the licenses is loaded from the configuration. If it is necessary to display a new license due to an extension of the application, this can simply be added to the configuration.

Here's an example:

Demo

If you check out this project, there is a "demo" app to see how the library works. Simply clone the repo and run npm run test in the demo folder ( npm install required to install all necessary packages ).

Getting started

Initialize the SRBJSLogger via the NPM CDN:

For initializing the Logger via CDN, simply copy and paste the following in the index file of the HTML5 app:

<script src="https://npmcdn.com/srbinfoandsupportjs/src/SRBInfoAndSupport.js"></script>

Or use the minified version

<script src="https://npmcdn.com/srbinfoandsupportjs/src/SRBInfoAndSupport.min.js"></script>

Initialize SRBInfoAndSupportJS via downloading the latest version:

Download the latest minified version from here. Place that file into a directory of the app's folder structure, where it can access that file. For UI5 apps, using the index.html bootrapping, instantiate the Logger like above via

<script src="/path/to/SRBInfoAndSupport.min.js"></script>

For UI5 apps, not using the index.html startup logic, paste the following in the ressources section of the manifest file:

"resources": { "js": [ { "uri": "path/to/SRBInfoAndSupport.min.js" } ] }

Initialize the Logger temporarily via the browsers console. Just copy, paste and execute the following snippet in the browsers console:

var script = document.createElement("script");
script.type = "text/javascript";
script.src = "https://npmcdn.com/srbinfoandsupportjs/src/SRBInfoAndSupport.min.js";
script.addEventListener("load", function () {
  SRBInfoAndSupport.init({
    appname: "My testing app",
    version: "1.1.1",
    licenses: { MyLicense: "ABCABC" },
    copyright: "My version of the copyright",
    latestCommitHash: "asf82oap",
  });
});

document.head.appendChild(script);

Documentation

The documentation on this page is just an overview of the most relevant functions and features. Consider reading the JSDoc page!

The init function

SRBInfoAndSupport.init({
  appname: "My testing app",
  version: "1.1.1",
  licenses: { MyLicense: "ABCABC" },
  copyright: "My version of the copyright",
  latestCommitHash: "asf82oap",
});

or, if using the manifest properties instead:

SRBInfoAndSupport.init();

Parameters

init(config[{}])

• config - optional Configuration object for the init function. If provided, the following config object has to be used:

  {
    "appname": "",
    "version": "",
    "licenses": {
      "MyLicense": ""
    },
    "copyright": "",
    "latestCommitHash": "asf82oap"
  }

  If this configuration object is not provided, the library is searching for manifest properties of the UI5 app, that is using the library.

  Example manifest.json configuration:

    {
      "_version": "1.0.162",
      "_srbVersionInfo": {
        "productName": "My Product",
        "latestCommitHash": "3704aa5",
        "copyright": "© Copyright 2022 SRB Consulting Team GmbH. All Rights Reserved.",
        "licenses": {
          "My Product License": "",
          "html2canvas": "Copyright (c) Microsoft Corporation. Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted. THE SOFTWARE IS PROVIDED 'AS IS' AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS. IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR ANY SPECIAL, DIRECT, INDIRECT, OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, WHETHER IN AN ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE."
        }
      },
      ...
    }
  

The support dialog function

SRBInfoAndSupport.showSupportDialog("My dialog title", {
  captureScreenshot: true,
});

Parameters

showSupportDialog(title[String], config[{}])

• title - optional

  The shown title of the support dialog

• config - optional Configuration object, configuring the support dialog.

  • captureScreenshot true|false Indicates if a screenshot of the app shall be captured. For this, a extrenal library html2canvas is necessary. This library is not shipped with the SRBInfoAndSupportJS. See https://github.com/niklasvh/html2canvas for how to initialize the library.

    Quick and dirty example that is initializing html2canvas. You can use it in the browser console:

    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "https://github.com/niklasvh/html2canvas/releases/download/v1.4.1/html2canvas.min.js";
    document.head.appendChild(script);

  Example:

  {
    "captureScreenshot": true
  }

Results in

The overview dialog function

SRBInfoAndSupport.showOverviewDialog("Title");

Parameters

showOverviewDialog(title[String])

• title

  The title of the info dialog

Results in

The initializing hidden info

This function initializes a hidden feature. The feature is open the overview dialog or the support dialog, or both. The magic thing is that the dialogs are shown only after clicking on a specific DOM element a specific number of times in a specific time range. The number of clicks is 10 in a time range of 2000 milliseconds.

The DOM element that has to be clicked can be forwarded to the function via the parameter domElementId. What will be showing is set via overviewDialog and/or supportDialog.

SRBInfoAndSupport.initHiddenInfo({
  overviewDialog: true,
  supportDialog: false,
  domElementId: "__component0---Startpage--filterSearch",
});

Parameters

initHiddenInfo(config[{}])

• config - optional Configuration object, configuring the hidden info feature.

  • overviewDialog true|false - optional

    Shows the overview dialog if the hidden info is triggered by the user.

  • supportDialog true|false - optional

    Shows the support dialog if the hidden info is triggered by the user.

  • domElementId String - optional

    The DOM element ID that the user has to click.
