JSONEditor4Menu

JSONEditor4Menu is a JSON Editor for creating HTML5 menus with CSS and HTML Templates for Hamburger Menus - based on JSON Editor of Jeremy Dorn

Generate WebApp with responsive web design:

JSONEditor4Menu can be used to create such AppLSACs in a Responsive Web Design.

The following table of contents is generated with node doctoc README.md.

Related Package for JSONEditor4Menu

This repository is related to the following packages:

Installation JSONEditor4Menu

The library was designed to used in a browser (WebApp). So use the installation for your browser by using a bundle dist/jsoneditor4menu.js (see example Demo JSONEditor4Menu).

Installation for Browsers

If you want to use the library jsoneditor4menu.js in a browser, please copy the file dist/jsoneditor4menu.js into your library folder of WebApp that you want to test with a browser (e.g. js/jsoneditor4menu.js). If you want expand existing examples check the basic example in docs/index.html first and play around with that HTML-file. If you want to import the library with script-tag do it in the standard way with:

<script src="js/jsoneditor4menu.js"></script>

Now it is possible to use the constructor of JSONEditor4Menu

if (JSONEditor4Code) {
  var vJSONEditor = new JSONEditor4Menu();
  vJSONEditor.initDoc(document);
}

Now we define a hash that contains the options for the init()-call.

var pOptions = {
        "editor_var": "vJSONEditor", // Variable in index.html that stores the JSONeditor
        "editor_id": "editor_holder", // ID of DOM element, that stores the editor.
        "validator_id":"valid_indicator",  // ID of DOM, that contains the validator result "valid" or "not valid"
        "filejson_id" : "fileJSON", // ID of DOM element that contains the JSON file upload
        "filename_id" : "display_filename", // innerHTML for DOM element to display the loaded filename
        "filename_key" : "data.classname",  // key that stores the basename for the filename
        "out_json": "tOutJSON", // ID of textarea to visualise the generated JSON
        "out_code": "tOutput", // ID of textarea to visualise the generated code/markdown with the templates in docs/tpl
        "out_errors": "tErrors" // ID of textarea that shows the errors in the loaded JSON
};

After the initDoc() call the JSONEditor4Menu is aware about the document in the browser.

Init the JSON Editor

The init method of the JSON Editor gets as parameter the follow JavaScript objects:

  • pJSON is JSON data with which the JSON Editor is populated,
  • pDefaultJSON is the JSON data which is used, when the JSON Editor is resetted,
  • pSchema is JSON Schema which defines the input elements of JSON Editor JSONEditor4Menu
  • vDataJSON.tpl is a hash of string templates for Handlebars4Code. vDataJSON.tpl is hash with defined template strings. With the template ID the Handlebars4Code template engine uses this template for code generation.
  • pOption are options for the JSON Editor.
vJSONEditor.init(vJSON,
  vDefaultJSON,
  vDataJSON["class_schema"],
  vDataJSON.tpl,
  vOptions);

vDataJSON is a JSON container for all the loaded data. Templates are loaded with script-tags (see docs/index.html):

<script src="tpl/javascript_tpl.js"></script>
<!-- ### COMPILE HANDLEBARS TEMPLATES  ############
Template ID: "docu4github"
Template: vDataJSON["tpl"]["docu4github"]
-->
<script src="tpl/docu4github_tpl.js"></script>
<!-- ### SCHEMA LOADER ############################
script tag stores the JSON schema in
vDataJSON.tpl.["class_schema"]
<script src="schema/class_uml_schema.js"></script>
-->
<script src="schema/class_uml_schema.js"></script>

Folder and Files in docs/

The folder docs/ contains all files for the web demo of this repository, that can be accessed to the https://___PKG_GITHUBUSER___.github.io/JSONEditor4Menu.

Files, Folders and Structure of Repository

The following enumeration explains the structure of the repository and folders.

  • dist/ folder contains the generated library from the build process npm run build
  • docs/ folder contains all the web content that you can access via gitlab.io defined in the settings of the GitHub repository as server root for the demo.
    • docs/ace folder contains files for the editor ACE, that is used in JSON-Editor to edit source code.
    • docs/db folder contains JSON database which initializes the JSON-Editor with the default JSON data. If the user saves the file, the current JSON data is stored in the LocalStorage of the browser.
    • docs/css folder contains all style sheet for the webbased demo in docs.
    • docs/fonts folder contains the fonts for the FontAwesome.
    • docs/jquery folder contains the JQuery implementation so that a webbased demo runs offline.
    • docs/js folder contains all Javascript libraries used for the webbased demo.
    • docs/schema folder contains JSON schema for the webbased demo created JSON2schema, defining the input user interface for editing the JSON file
    • docs/tpl folder contains the HandleBars template generating the source code from the UML definition.
    • docs/index.html files starts the webbased demo.
  • jscc/ folder contains the JavascriptClassCreator files that are used to create object-oriented Javascript class files.
  • src/ folder contains the file main.js for NPM defined in package.json and other source files in the future, to create a the library for webbased use in a browser can be found in the folder dist/. The files in dist/ are created with browsersify and/or watchify.
  • update_src_libs.sh is a shell script that works on Linux and MacOSX to perform some library updates from the web and the update_src_libs.sh can be used to initialize a new repository with the basic WebApp structure as an privacy friendly AppLSAC.

Quick Start for Users of JSONEditor4Menu

Just download the ZIP-file of the JSONEditor4Menu repository. For using the AppLSAC unzip the file and navigate to the docs/-folder and load the docs/index.html in your browser as privacy-friendly AppLSAC-2. All files, that are equired for the AppLSAC to run are stored in the docs folder. Only if you are planing the change the source code of the AppLSAC JSONEditor4Menu you need the other folders.

If you just want to use JSONEditor4Menu in your browser it is recommended to

  • copy just the docs/-folder,
  • rename the folder to jsoneditor4menu/ and
  • start index.html with your browser as AppLSAC-2.

Templates for Handlebars4Code

For generation of the output files a template engine Handlebars4Code was used. It adds some additional helper functions to the original Handlebars.

In the Handlebars4Code demo the JSON data is stored in vDataJSON, which is the main JSON data storage defined in index.html. Data is located in (docs/db/) and the templates in the folder (docs/tpl/) are loaded into the JSON vDataJSON with a script-tag and loaded as a standard Javascript library. All predefined templates reside in vDataJSON.tpl, which is provided as parameter to Handlebars4Code.create_compiler(vDataJSON.tpl). The method create_compiler(vDataJSON.tpl) creates Handlebars compilers for all templates in vDataJSON.tpl.

  • create_compiler(vTplHash) expects a hash, for which the template ID is the key for accessing template (e.g. vDataJSON.tpl["docu4github"]) or vDataJSON.tpl["javascript"]) (see directory docs/tpl/).
  • The compilers need to be generated only once. Then the compiler for all templates are ready to process JSON data and generate output according to the template definition.
  • var my_compilers = Handlebars4Code.get_compiler() stores the generated Handlebars compilers in an individual compiler hash. var my_output = my_compilers.javascript(vJSON) provides JSON to the compiler function for the template javascript. var my_output = my_compilers.docu4github(vJSON) provides JSON to the compiler function for the template docu4github.

vDataJSON as Template Storage

Create a template storage in your main HTML file.

<script language="javascript">
  var vDataJSON = {};
  vDataJSON.tpl = {};
  vDataJSON.out = {};
</script>

vDataJSON.out contain the compilers, that are generated by Handelbars4Code. Each compiler in vDataJSON.out have are corresponding template in vDataJSON.tpl. vDataJSON.tpl is hash of strings for each ID and vDataJSON.out is hash of functions with the corresponding ID. The following code generates the compiler with HandleBars4Code.

Handlebars4Code.create_compiler(vDataJSON.tpl);
vDataJSON.out = Handlebars4Code.get_compiler();

Assume you have a template with the ID mytpl you will get a compiler function in vDataJSON.out.mytpl() that you can populate with JSON data. The call of vDataJSON.out.mytpl(pMyData) will replace the JSON data pMyData in the template mytpl.

Templates and JSON into vDataJSON

The javascript files in docs/tpl/ and docs/db/ are designed in way that allows the population of vDataJSON just by including a script tag in the underlying HTML file (see example docs/index.html).

Load JSON Data with Script Tag

The following script tag loads the JSON data into vDataJSON.

<script src="db/umljs.js"></script>

The data is stored in the following way in the JavaScript file:

vDataJSON["umljs"]= {
  "author": "Bert Niehaus",
  "description": "My description for repository."
}

It is recommended to use the same ID in vDataJSON as the basename of the corresponding JavaScript file db/umljs.js without path db/ and extension .js.

Load Templates with Script Tag

Every script tag loads a single template from the subdirectory docs/js/:

<script src="tpl/javascript_tpl.js"></script>
<script src="tpl/docu4github_tpl.js"></script>

Script Tag for handlebars4code.js

Use the script tag to embed the Handlebars4Code library in your HTML file::

<script src="js/handlebars4code.js"></script>

Additional Handlebars Helpers for Code generation

The following Handlebars helpers are added to the basic Handlebars features, to support better code generation. Generated code can be in any programming language (of course including markup or markdown languages):

List of Helpers in Handlebars4Code

  • filename create lower case filenames from camel-case class names (e.g. MyClass into myclass).
  • ifcond creates id-conditions in the Handlebars template to create JSON context dependent compiler output.
  • require_class_list inserts require commands according the used classes in the attributes and return values of the methods. It requires only modules that are not base classes that are provided by the programming language itself.
  • requirelibs The helper is designed to generate local and remote require commands in a class/module.
  • foreach is slighty different from the standard each helper in Handlebars. It allows to assign parent data hash to foreach context of the template

Helper: filename

The helper function filename generates from any input string a usable filename in lowercase that contains no blanks an no special characters.

Template 1: filename

Assume we have the following templates stored vDataJSON.tpl["mytpl1"] with

// The filename of the class {{data.classname}} is {{filename data.classname}}.js

The template ID mytpl1 is

JSON Data 1: filename

The following JSON

var my_json = {
  "data":{
    "classname" : "MyClass"
  }
}

Compiler Output 1: filename

The compiler call Handlebars4Code.compile.mytpl1(my_json) for the JSON data my_json and the template generates the following code

// The filename of the class MyClass is myclass.js

JSON Data 2: filename

The following JSON

var my_json = {
  "data":{
    "classname" : "MyClass",
    "superclassname" : "MySuperClass"
  }
}

Template 2: filename

Assume we have templates vDataJSON.tpl["mytpl2"] with:

const {{data.superclassname}} = require('{{filename data.superclassname}}');

Compiler Output 2: filename

The compiler call Handlebars4Code.compile.mytpl2(my_json) for the JSON data my_json and the template generates the following code:

const MySuperClass = require('mysuperclass');

If the input string contains blanks then these blanks are replaced by an underscore.

Helper: ifcond

If condition and application of JSON path to specific attribute to JSON. The following template generates a header as comment for the javascript output. Dependent on the value of data.superclassname (string not empty) an additional name for the superclass is inserted in the header of generated output of code (see Blog in StackOverflow)

Template: ifcond

Assume we have the following templates is stored vDataJSON.tpl["mytpl"] with

//#################################################################
//# Javascript Class: {{data.classname}}()
{{#ifcond data.superclassname "!=" ""}}
//#       SuperClass: {{data.superclassname}}
{{/ifcond}}
//#
//# Author of Class:      {{data.reposinfo.author}}
//# email:                {{data.reposinfo.email}}
//#################################################################

The ifcond is an if-condition, that inserts a line with name of the super class if the superclassname is not empty.

JSON Data: ifcond

The following JSON is used the helper call:

var my_json = {
    "data": {
      "classname": "NewClass",
      "superclassname": "MySuperClass",
      "comment": "Description of the class",
      "reposinfo": {
        "repository": "https://www.github.com/author/NewClass",
        "author": "My Name",
        "email": "name@example.com",
      },
    }
  };

The superclassname is not empty and has the value "MySuperClass". The ifcond used in the template will insert a line by the use of an if-condition.

Compiler Output: ifcond

The compiler call for the JSON data and the template generates the following code:

//#################################################################
//# Javascript Class: NewClass()
//#       SuperClass: MySuperClass
//#
//# Author of Class:      My Name
//# email:                name@example.com
//#################################################################

The compiled result contains a comment about the super class, due to the fact that the attribute superclassname is not empty and contains the value "MySuperClass".

Helper: require_class_list

The helper function creates a list of liberaries that must be required/imported (e.g. Javascript) so that the defined libary for the new class can used the required resources in other modules. Some classes/instances are already defined by the programming language (e.g. Math, JSON in Javascript). Those libraries do not need a require command. The code generator should know about

  • base classes (baseclasslist) - no need to create require
  • local classes (localclasslist) - store in local directory, a path is necessary to these locally defined libraries (see data.reposinfo.require_path).
  • remote classes (remoteclasslist) - retrieved from a remote server via a package manager.

Template: require_class_list

Assume we have the following templates stored vDataJSON.tpl["mytpl"] with

{{{require_class_list data settings}}}

The helper needs the data and the settings attribute of the JSON input as parameter:

  • data contains all the defined elements of the class.
  • settings contain basic definitions for the classes that are available in the software development project.
  • data.superclassname because a superclass will be handled with a separate require command.
  • settings.baseclasses because those classes are provided by the programming language by default and they do not need a require command.
  • settings.localclasses because those classes are created within the software developement of the repository and these modules need a special require command with a local pathname, where to to find the libraries, e.g. require('./libs/mylocallib').
  • data.reposinfor.require_path contain the local path to the libraries/modules of localclasses ./libs/.
  • settings.remoteclasses remote classes are download with a package manager and these modules are required just by the module name, e.g. require('mylocallib').

JSON Data: require_class_list

The following JSON

var my_json = {
  "data": {
    "classname": "NewClass",
    "superclassname": "MySuperClass"
  },
  "settings": {
    "extension4code":".js",
    "localclasslist": [
      "App",
      "AppAbstract"
    ],
    "remoteclasslist": [
      "LinkParam",
      "JSONEditor"
    ],
    "baseclasslist": [
      "",
      "Array",
      "Boolean",
      "Float",
      "Function",
      "Hash",
      "Integer",
      "Object",
      "RegularExp",
      "String"
    ]
  }  
};

Compiler Output: require_class_list

Assume that App, LinkParam and JSONEditor are used in the class as attributes or returned instances of method. App is a locally defined class while LinkParam and JSONEditor are remote classes downloaded from the package manager (e.g. NPM). The compiler call for the JSON data and the template generates the following code.

require('./libs/app');
require('linkparam');
require('jsoneditor');

Helper: requirelibs

The helper is designed to generate local and remote require commands in a class/module.

Template: requirelibs

Assume we have the following templates is stored vDataJSON.tpl["requiretpl"] with:

// NodeJS: Require additional Modules
{{#requirelibs data.reposinfo.requirelist}}
const {{variable}} = require('{{module}}');
{{/requirelibs}}

JSON Data: requirelibs

The following JSON is used the helper call:

var my_json = {
    "data": {
      "classname": "NewClass",
      "reposinfo": {
        "requirelist": [
          {
            "module":"handlebars",
            "variable":"Handlebars"
          },
          {
            "module":"filesaver",
            "variable":"FileSaver"
          },
          {
            "module":"jquery",
            "variable":"$"
          }
        ]
      },
    }
  };

Compiler Output: requirelibs

The compiler call Handlebars4Code.compile.requiretpl(my_json) for the JSON data my_json and the template generates the following code. The variable for the repository uses the module name in the requirelist and creates a variable name with an uppercase first character of the module name.

const Handlebars = require('handlebars');
const Filesaver  = require('filesaver');  
const $          = require('jquery');

Helper: foreach

The example for the foreach helper will generate HTML code e.g. for the document explaining the available methods in the class. The example for the paramcall helper provides an application of foreach for code generation.

Template: foreach

Assume we have the following templates stored in vDataJSON.tpl["htmltpl"] with:

<ul>
{{#foreach data.methods data}}
  <li>
  The {{visibility}} method {{name}} is defined in class {{data.classname}}
  </li>
{{/foreach}}
</ul>

Parameter of Helper: foreach

The output format is HTML and the template uses

  • the array data.methods to iterate over all methods and
  • the hash data as second parameter of the helper, so that parent attribute of the JSON like data.classname are available in the content of the foreach definition as well.
  • The second parameter data is added as data attribute to method items the array data.methods. You can assign a different hash e.g. mydata to the second parameter. For the template above the hash mydata needs the attribute mydata.classname. The second parameter is still mapped to {{data}} in the helper context. So if mydata.classname="MyNewClass2" the Handlebars {{data.classname}} will be set to MyNewClass2. With the new second parameter the template context will look this:
<ul>
{{#foreach data.methods mydata}}
  <li>
  The {{visibility}} method {{name}}(params) is defined in class {{data.classname}}
  </li>
{{/foreach}}
</ul>

For a Handlebars4Code helper foreach helper is called for arrays myarray with:

{{#foreach myarray data}}
    context for each array element
{{/foreach}}

JSON Data: foreach

The following JSON is used the helper call:

var my_json = {
    "data": {
      "classname": "NewClass",
      "methods": [
        {
          "visibility": "public",
          "name": "init",
        },
        {
          "visibility": "private",
          "name": "create",
        },
        {
          "visibility": "public",
          "name": "display",
        }
    }
  };

Compiler Output: foreach

The template was stored in vDataJSON.tpl["htmltpl"], so the compiler call will be Handlebars4Code.compile.htmltpl(my_json) for the JSON data my_json. The defined template generates the following code:

<ul>
  <li>
  The public method init(params) is defined in class NewClass
  </li>
  <li>
  The private method create(params) is defined in class NewClass
  </li>
  <li>
  The public method display(params) is defined in class NewClass
  </li>
</ul>

Helper: paramcall

The helper paramcall creates a list of parameter names of the method, that is comma separated.

Template: paramcall

Assume we have the following templates stored in vDataJSON.tpl["methodtpl"] with:

{{#foreach data.methods data}}
{{#ifcond visibility "==" "public"}}
    {{data.classname}}.{{name}} = function ({{#paramcall parameter}}{{/paramcall}})
{{/ifcond}}
{{#ifcond visibility "==" "private"}}
    // private function of class {{data.classname}}
    function {{name}}({{#paramcall parameter}}{{/paramcall}})
{{/ifcond}}
{{/foreach}}

The foreach helper iterates of all method (here only one method is defined in the class). The ifcond helper distinguishes between different outputs for public and private methods in the class.

JSON Data: paramcall

The following JSON is used for the helper call. The JSON contains one method with

var my_json = {
    "data": {
      "classname": "NewClass",
      "superclassname": "MySuperClass",
      "methods": [
        {
          "visibility": "public",
          "name": "init",
          "parameter": [
            {
              "name": "pJSON",
              "class": "Hash",
              "comment": "the parameter stores JSON definition for the class"
            },
            {
              "name": "pOptions",
              "class": "Hash",
              "comment": "the parameter stores the options for the JSON editor (developed by Jeremy Dorn)"
            },
            {
              "name": "pSchema",
              "class": "Hash",
              "comment": "the parameter contains the JSON Schema for JSON Editor"
            }
          ]
        }
    }
  };

Compiler Output: paramcall

The compiler call Handlebars4Code.compile.methodtpl(my_json) for the JSON data my_json and the template generates the following code:

NewClass.init = function (pJSON,pOptions,pSchmea)

The ifcond condition creates a different output if the visibility attribute is set to private. The generated code will be:

// private function of class NewClass
function init(pJSON,pOptions,pSchmea);

Helper: parameterlist

The helper function parameterlist is mainly used to insert a comments for all parameter of a function in the header of a function.

Template: parameterlist

Assume we have the following templates stored vDataJSON.tpl["mytpl"] with:

//#################################################################
//# {{visibility}} Method: {{name}}()  Class: {{data.classname}}
//# Parameter:
//#    {{parameterlist parameter "    //#    "}}
//#################################################################

JSON Data: parameterlist

The following JSON is used the helper call:

var my_json = {
  var my_json = {
      "data": {
        "classname": "NewClass",
        "superclassname": "MySuperClass",
        "methods": [
          {
            "visibility": "public",
            "name": "init",
            "parameter": [
              {
                "name": "pJSON",
                "class": "Hash",
                "comment": "the parameter stores JSON definition for the class"
              },
              {
                "name": "pOptions",
                "class": "Hash",
                "comment": "the parameter stores the options for the JSON editor (developed by Jeremy Dorn)"
              },
              {
                "name": "pEditorID",
                "class": "String",
                "comment": "the parameter provide DOM ID in which the JSON editor will be injected."
              }
            ]
          }
      }
    };

Compiler Output: parameterlist

The compiler call Handlebars4Code.compile.mytpl2(my_json) for the JSON data my_json and the template generates the following code:

//#################################################################
//# public Method: init()  Class: NewClass
//# Parameter:
//#    pJSON:Hash
//#      the parameter stores JSON definition for the class
//#    pOptions:Hash
//#      the parameter stores the options for the JSON editor (developed by Jeremy Dorn)
//#    pEditorID:String
//#      the parameter provide DOM ID in which the JSON editor will be injected.
//#
//#################################################################

Helper: indent

The helper function indent takes two parameters.

  • the text (e.g. comment or code)
  • the indent which is injected for all newlines in the text parameter. The indent helper shifts the text or code to the right.

Template: indent

Assume we have the following templates is stored vDataJSON.tpl["mytpl"] with:

   //#################################################################
   //# Comment:
{{indent comment "    //#     "}}
   //# Line after Comment
   //#################################################################

JSON Data: indent

The following JSON is used the helper call:

var my_json = {
    "data": {
      "classname": "NewClass",
      "superclassname": "MySuperClass",
      "methods": [
        {
          "visibility": "private",
          "name": "create",
          "comment":"one line \nsecond line\nthird  line"
        }
    },
    "settings": {

    }
  };

Compiler Output: indent

The compiler call Handlebars4Code.compile.mytpl(my_json) for the JSON data my_json and the template generates the following code:

    //#################################################################
    //# Comment:
    //#     one line
    //#     second line
    //#     third line
    //# Line after Comment
    //#################################################################

JSON2Schema for JSONEditor4Menu

The user interface of the JSON Editor is defined by a JSON schema. JSON Editor takes a JSON Schema and uses it to generate an HTML form.
It has full support for JSON Schema version 3 and 4 and can integrate with several popular CSS frameworks (bootstrap, foundation, and jQueryUI).

Check out an interactive demo (demo.html):

https://json-editor.github.io/json-editor/

JSON Editor has no dependencies. It only needs a modern browser (tested in Chrome and Firefox).

The JSONEditor4Menu uses the JSON Editor orginally developed by Jeremy Dorn and you can use the same type of JSON Schema.

If you want to create a new JSONEditor4Menu with additional attributes for editing the menu you can replace the JSON Schema in docs/schema/menu_schema.js that defines currently the graphical user interface (GUI) for the provided example of JSONEditor4Menu just make a copy of the docs/schema/menu_schema.js -folder in this repository JSONEditor4Menu and adapt the JSON-schema docs/schema and the JSON data in the folder docs/db/ to the schema for your requirements. If you want to create your own JSON schema use JSON2Schema.

Optional Requirements

The following are not required, but can improve the style and usability of JSON Editor when present.

  • A compatible JS template engine (Mustache, Underscore, Hogan, Handlebars, Swig, Markup, or EJS)
  • A compatible CSS framework for styling (bootstrap 2/3, foundation 3/4/5, or jqueryui)
  • A compatible icon library (bootstrap 2/3 glyphicons, foundation icons 2/3, jqueryui, or font awesome 3/4)
  • SCEditor for WYSIWYG editing of HTML or BBCode content
  • SimpleMDE for editing of Markdown content
  • Ace Editor for editing code
  • Select2 for nicer Select boxes
  • Selectize for nicer Select & Array boxes
  • math.js for more accurate floating point math (multipleOf, divisibleBy, etc.)

If you learn best by example, check these out to understand the basic prinples of using a JSON editor:

Menu Icon Selector in Schema

The file docs/schema/menu_schema.js defines the JSON schema for the JSON editor. In the definitions part of the JSON schema the selectoricon defines the all available icons for the menu. The used icons are CC0 icons from JQuery Mobile 1.4.5 Font Awesome Icons 4.7.0 to the selector expand the following part of the file docs/schema/menu_schema.js according to your needs.

The enum_titles define the name in the selector and the enum array defines the strings that are use

"selectoricon": {
  "type": "string",
  "title": "Menu Icon",
  "default": "",
  "enum":[
      "",
      "folder-open-o",
      "floppy-o",
      "cog",
      "trash"
  ],
  "options": {
    "enum_titles": [
      "NO ICON",
      "Load",
      "Save",
      "Settings",
      "Trash"
    ]
  }
}

Icon Contact: Assume you want to add a menu item for sending a message to the developer, institution or company. The contact information provides e.g. an e-mail address, so we select from the Wiki Commons an appropriate SVG icon. In this example we select the icon with the name envelop-o and some other icons that expand the selectoricon with the following lines.

"selectoricon": {
  "type": "string",
  "title": "Menu Icon",
  "default": "",
  "enum":[
      "circle-thin",
      "home",
      "folder-open-o",
      "floppy-o",
      "pencil-square-o",
      "calendar",
      "camera",
      "line-chart",
      "fa-picture-o",
      "envelope-o",
      "phone",
      "power-off",
      "search",
      "cog",
      "trash",
      "file-archive-o"
  ],
  "options": {
    "enum_titles": [
      " ",
      "Home",
      "Load",
      "Save",
      "Edit",
      "Calendar",
      "Camera",
      "Chart/Diagrams",
      "Images",
      "Mail",
      "Phone",
      "Quit/Exit",
      "Search",
      "Settings",
      "Trash",
      "ZIP"
    ]
  }
}

The underlying library is Icons4Menu on GitHub.

Build Process of npm run build

As a developer it is assumed that you have:

  • NodeJS and
  • git installed on your computer.

The build process must be called with npm run build. If you want change the existing code for JSONEditor4Menu clone the code from the Git-repository with:

git clone https://github.com/niebert/jsoneditor4menu.git

The you will have a folder jsoneditor4menu/ with all the files in your local file system. The code part for the build process are stored in the folder jsoneditor4menu/src/.

Now all the dependent libraries must be installed with:

npm install

You will find an additional folder node_modules/ in your cloned copy of jsoneditor4menu.

The build process is started by calling by npm run build which in turn call build.js. If you want to call the build process of build.js separately just call build.js with node build.js from the shell/console.

The templates for building the output are stored in the folder src/.

After the build process the README.md is generated and if you want to have the table of contents in the file for the concatenation of files in src/readme/ listed in files4build.js then you must run the DocToc generator for README.md by doctoc README.md from the shell to update the table of contents in README.md.

Define Filename for build in package.json

In package.json defines the filename for the automated build for

  • README.md for readme for the repository (parts in src/readme),
  • index.html for the web demo (parts in src/html),
  • main.css for the style sheet (part in src/css) and
  • src/main.js is generated from the parts in src/libs the sources in src/. To specify these filenames add the following build section to the package.json:
"build": {
  "readme": "README.md",
  "html": "docs/index.html",
  "css": "docs/css/main.css"
}

If you want to edit the generated file check the files that are selected for including into the generated files (see files4build.js) and set the files to a preliminary build name (e.g. like index_build.html instead of index.html to compare generated file index_build.html with the older version index.html for debugging

Compress after Build

After building (concat the file parts) and replacement of package variables (e.g. see build4code like jsoneditor4menu for package name) in the generated documents the module is browserified by the command

uglifyjs dist/jsoneditor4menu.js --compress -o dist/jsoneditor4menu.min.js

This command is called after build.js and the final step of the build process is the doctoc call to update the table of contents in the README.md. All steps of the npm run build command are defined in the script section of the package.json file.

Build and Compress with Browserify, Watchify, UglifyJS

The NodeJS modules can use require()-command. Browsers cannot execute the require()-command and other node specific programming features.

  • Browserify loads the file src/main.js as input file and resolves e.g. the require()-command and creates an output file in dist/jsoneditor4menu.brows.js
  • Watchify observes any changes in the source files in src/ and starts on the event of changes the build process of the file src/main.js as input file and creates an output file in dist/jsoneditor4menu.brows.js.
  • UglifyJS compresses the code in dist and takes the file dist/jsoneditor4menu.js and generates the compressed library in dist/jsoneditor4menu.min.js. The same is applied for docs/js/jsoneditor4menu.js and the output is docs/js/jsoneditor4menu.min.js. The compression of the source code can be perform without a total build by npm run compress.

Browserify and Watchify

Browserify and Watchify are used in this repository to control the WebApp-javascript development with the required Javascript libraries installed with NPM Node.js and similar framework world that greatly improve your javascript workflow: Using them, you no longer need to micro-manage your script tags but instead you just declare the libraries each of your client-side modules is using - or you can even create your own reusable modules! Also, installing (or updating) javascript libraries is as easy as running a single command!

Global Installation of Browserify, Watchify, UglifyJS and DocToc

Requirement: NPM is intalled. Now call for global installation of Browserfy, Watchify, UglifyJS and DocToc by:

npm install -g browserify watchify uglify-js doctoc

This is recommended because your will not install Browserfy, Watchify and UglifyJS for all your repositories separately.

  • Browserfy converts node_modules in a single library, that can be imported in WebApp. Browserify resolves dependencies and included the required libraries into the bundled javascript code.
  • Watchify watches changes in the source code and runs the build process whenever it detects changes in the your source code.
  • UglifyJS compresses the source code of dist/class_editor_uml.js into class_editor_uml.min.js to reduce download time and WebApp performance during load.
  • DocToc is used to create a helpful table of contents in the README (see DocToc-Installationhttps://github.com/thlorenz/doctoc#installation) for further details on NPM DocToc ). Run doctoc README.md for updating the table of contents.
  • jsLint is used to check the Javascript code, quality of code can be improved by application of jsLint

Package Installation of Browserify and Watchify - Alternative

If your prefer that browserify and watchify is installed with your npm install command, save these to modules to your dev-dependecies in your package.json by calling

  • (Install Browsersify) npm install browserify --save-dev
  • (Install Watchify) npm install watchify --save-dev
  • (Install UglifyJS) npm install uglify-js --save-dev
  • (Install DocToc) npm install doctoc -g
  • (Install jshint) npm install jslint -g

The difference between --save and --save-dev is, that development dependencies are installed with npm install because they are required for the development process of the code but they are not added to the generated Javascript-bundle that are used in the WebApp ClassEditorUML. The --save-dev commands for browserify and watchify will install the two modules with all the the dependencies in node_modules and add the dev-dependencies to your package.json.

"devDependencies": {
  "browserify": "^14.5.0",
  "watchify": "^3.9.0",
  "uglify-js": "^2.6.2",
  "doctoc":"^1.3.0",
  "lint": "^1.1.2"  
}

In the current repository Browserfy and Watchify are expected to be installed globally, because the package.json does not contain the dev-dependencies mentioned above.

Start Watching the Files with Watchify

Watchify will trigger the npm run build process if files were change due to alteration of code. To start watching the files, run the npm-watch script by npm run watch, which is defined in package.json

Source JS file and development bundle output

The main JS source file for the build process is src/main.js. The output library (resp. output file of build process) is stored in distrubtion library for browser based web-development in dist/jsoneditor4menu.js. Compressed code is generated with UglifyJS. It takes the dist/jsoneditor4menu.js as input file and creates the compressed file dist/jsoneditor4menu.min.js. The compression of dist/jsoneditor4menu.js into dist/jsoneditor4menu.min.js uses uglify-js module and can be started by

npm run compress

  • JSON-Editor by Jeremy Dorn. The JSON Editor takes a JSON Schema and uses it to generate an HTML form. The JSON-Editor is partially used to edit JSON file of the JavascriptClassCreator Project JSCC. The JSON-Editor of Jeremy Dorn has full support for JSON Schema version 3 and 4 and can integrate with several popular CSS frameworks (bootstrap, foundation, and jQueryUI). This would lead to major code reduction of JSCC . Refactoring of JSCC would make more use of the JSON-Editor features. Check out an interactive demo (demo.html): http://jeremydorn.com/json-editor/

With this library the users are able load files into your browser application and process the data in the browser and provide the output to the user, without submitting any data to a server. Demo LoadFile4DOM
  • FileSaver.js Developer Eli Grey provided the FileSaver.js that is used to store created JSCC files to the local filesystem. JSCC uses the same mechanism of browsers, that allows a Save as... in the context menu of a web pages or image. So not uncontrolled write access to your file system is implemented, because users have to select the locations in which the user whats to store the file (e.g. JSON, Javascript or HTML).
