near-solution is an environment to develop mobile-oriented apps.

Features

• It is based on module structure.
  • You can configure related feature sets for each module.
  • It is removable by module.
  • You can define dependencies between modules. Apply nodejs module dependency structure.
• Redux pattern
• Use i18next for internationalization
• Packaging function uses webpack
• The code set is based on es6,7,8, and transpiling with babel
  • class-properties
  • decorators
  • object-rest-spread
• Using Web Component-based DomElement - Defining custom element with LitElement
• It is activated by linking with URL path and history in Single Page Application.
• Each page is loaded at the time of initial activation. (lazy loading)
• Zero Configuration function. It uses SSDP (Service Discovery Protocol) to automatically find services to be connected automatically and provide related functions. For example, it attempts to connect automatically by finding a server to connect to.
• Token-based authentication (requires improvement to be supported by the server framework)

Structural conventions

• Redux
  • The way to manage the overall state of an Application is using Redux pattern.
  • The application, or base modules, can prepare points in the store that can be extended by a sub-module and provide an action.
  • The sub-modules connect to the extension structure of the application or parent module using the action defined in the parent (base) module.
• Page, Layout and Component
  • Pages are activated by associating with the URL. (route)
  • Layouts provide a framework for the layout and structure of the entire application UI elements.
  • The components provide independent (atomic) functionality.
    • The component excludes dependencies on the application in order to maintain implementation independence.
      • Style maintains its independence by using css variables.
      • Multilinguals maintain independence by using i18n-msg components. (Only have dependencies on i18n-msg.)
      • The component does not have a premise for the layout (display, position) of the host (container) to which it will be used.
  • page, layouts are connected to redux.
  • Components do not connect to redux, but they work with pages through properties.
• Base Module and extension (common) Modules (ex. provider, ui)
  • The Base Module provides an abstract definition of special functions.
  • The Base Module is said to provide functional services to the extension module.
  • The extension module can add the base module as a dependent module and directly use the functions defined in the base module.
  • Another way the extension module extends the Base Module is by using the reducer and action added to the store.
  • The Base Module is a base module that reads a group of modules. For example, board-base module is a base module for all board functions. In addition, label-base module defines and implements functions related to the label, including barcode label pop-up, barcode label scanning, barcode label rendering and printing.
  • The naming convention of base module for xxx module is 'xxx-base'.
• Provider Module
  • Sub-module that fills the data of Base module
  • It mainly serves to fill the data defined in Base module from the external server.
  • The naming convention for Provider module of xxx module is 'xxx-provider'.
  • If it is necessary to be distinguished by the way data is provided, the naming convention for Provider module of xxx module using yyy method can be defined as 'xxx-provider-yyy'.
• UI Module
  • Sub-module responsible for the screen configuration related to Base module
  • The naming convention for UI module of xxx module is 'xxx-ui'.
  • If it is necessary to be distinguished by UI configuration method, the naming convention for UI module of xxx module using yyy method may be 'xxx-ui-yyy'.
• Shell, Module and Application
  • Shell provides all the structures that enable the module structure in the development and execution stages.
    • redux, assets, routing
    • build module, build application
  • Module is only responsible for implementing its own purpose in the Shell base.
  • Application is the final product that consists of the modules necessary for the purpose of Shell and the user.
    • Configurations by Application
      • Manifest file (brand-related - application name, logo image)
      • Other brand related - homepage link, banner logo
      • Style : Representative color table, other css variables
      • Server connection IP
      • Other source/resource override

Other coding conventions

• Source file length recommended

  • Each source file implements one of the most important purposes. (Be responsible for simple purposes rather than multiple purposes.)
  • If there is no specific reason for each source file, it is recommended not to exceed 200 lines.

• Naming

  • class
    • Class name : starts with uppercase, camel-case
    • private property, method : starts with _(underscore), camel-case
    • public property, method : starts with lowercase, camel-case
    • class property, method : starts with lowercase, camel-case
    • Event handler : starts with on + EventName, camel-case

• Localization

  • Don’t capitalize explicitly in locale file

"field.system brief": "System Brief" (x)
"field.system brief": "system brief" (o)

You can set it to style where you need it.

text-transform: capitalize;
text-transform: uppercase;

• If possible, use ‘ms.json’ rather than ‘ms-My.json’. In particular, use ‘ms-My’ only if it is a Malay language that is used differently only in Malaysia.

Authentication

near-solution/shell

• Control the authentication process through auth base.
  • Set authentication through auth base.
• Provide auth action.
  • You can change store through authentication related action.
• Provide auth reducer.
• That is, it sets through auth base and provides auth-related extension point.
• In particular, auth base function is provided directly in near-solution shell.

near-solution/auth-ui

• Provide the client side authentication process based on JSON webtoken.
