Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Grunt plugin for code generation view models by models description

Build Status

This repository provides a grunt plugin for code generation view models by models description.

Установка

npm install grunt-generate-view-model

Как начать использовать

  • Создайте gencofig.json в корневом каталоге
{
    "check":
        {
            "folders":[
                "./models"
            ]
        }
}

Свойство "folders" показывает для каких папок(и их внутренних папок) нужны модели отображений.

  • Установите декораторы на нужные модели
import { InnerClass } from "./innerClass";
import {GenerateView, ViewModelType} from "grunt-generate-view-model";
import {InnerClassView } from "../generated/viewmodels/innerClassView";
import {fromModelToView, fromViewtoModel} from '../function/transformFunction';

@GenerateView({
    'model':'ClassView',
    'filePath':'./generated/viewmodels',
    'mapperPath':'./generated/mappers'})
export class Class {
    public property1: number;

    public property2: Object;

    public property3: string[];
    @ViewModelType({'type': InnerClassView,
    'transformer':{
        "toView":{'function':fromModelToView, "isAsync":true},
        "fromView":{'function': fromViewtoModel}}})
    public property4: InnerClass;

    @ViewModelType({'type': InnerClassView})
    public property5: InnerClass;

    public property6: InnerClass[];
    
    @IgnoreViewModel()
    public property7: number[]

}
  • В package.json добавьте инициализирующую команду в свойство "scripts":
  "scripts": {
    "generation": "generateView"
  }

где "generateView" - строка для запуска плагина

  • npm run generation

  • после завершения работы плагина по пути, указанному в декораторе GenerateView, появятся файлы с расширением ".ts" :

view model

import { InnerClassView } from './innerClassView';
import { InnerClass } from '../../models/innerClass';

  export class ClassView {

  public property1: number;

  public property2: Object;

  public property3: string [];

  public property4: InnerClassView;

  public property5: InnerClassView;

  public property6: InnerClass [];
}

mapper

  import { ClassView } from '../viewmodels/classView';
import { Class } from '../../models/class';
import { fromModelToView,fromViewtoModel } from '../../function/transformFunction';
import { InnerClassViewMapper } from './InnerClassViewMapper';

export class ClassViewMapper {
      public static async toClassView(model: Class): Promise<ClassView> {
            let result = new ClassView();
            result.property1 = model.property1;
            if (model.property2) {
                  result.property2 = JSON.parse(JSON.stringify(model.property2));
            }
            if (model.property3) {
                  result.property3 =  model.property3.map(function(item: any ) { return JSON.parse(JSON.stringify(item)); });
            }
            result.property4  = await fromModelToView(model);
            if (model.property5) {
                  result.property5 =  await InnerClassViewMapper.toInnerClassView(model.property5);
            }
            if (model.property6) {
                  result.property6 =  model.property6.map(function(item: any ) { return JSON.parse(JSON.stringify(item)); });
            }
            return result;
      }
      public static async fromClassView(viewModel: ClassView): Promise<Class> {
            let result = new Class();
            result.property1 = viewModel.property1;
            if (viewModel.property2) {
                  result.property2 = JSON.parse(JSON.stringify(viewModel.property2));
            }
            if (viewModel.property3) {
                  result.property3 =  viewModel.property3.map(function(item: any ) { return JSON.parse(JSON.stringify( item )); });
            }
            result.property4  =  fromViewtoModel(viewModel);
            if (viewModel.property5) {
                  result.property5 =  await InnerClassViewMapper.fromInnerClassView(viewModel.property5);
            }
            if (viewModel.property6) {
                  result.property6 =  viewModel.property6.map(function(item: any ) { return JSON.parse(JSON.stringify( item )); });
            }
            return result;
      }
}

Декораторы

В этом плагине используются 4 декоратора: 1 для классов и 3 для свойств

Декораторы для классов

GenerateView

Основной декоратор для создания моделей отображения

+-------------+--------------+-------------------------------------------------------+
|                        @GenerateView                                               |
+------------------------------------------------------------------------------------+
|   Property  |  Mandatory   |                      Definition                       |
+-------------+--------------+-------------------------------------------------------+
| model       | true         | name of view model                                    |
| filePath    | true         | path to view model relative to the root of the folder |
| mapperpath  | false        | path to mapper                                        |
+-------------+--------------+-------------------------------------------------------+

Можно создавать несколько моделей отображения от одной базовой модели.

@GenerateView({
    'model':'ClassView',
    'filePath':'./generated/viewmodels',
    'mapperPath':'./generated/mappers'})

Декораторы для свойств

ViewModelName

Декоратор, который используется для переименования свойства у модели отображения.

+------------------------------------------------------------------------------------+
|                        @ViewModelName                                              |
+------------------------------------------------------------------------------------+
|   Property             |  Mandatory   |              Definition                    |
+------------------------+--------------+--------------------------------------------+
| 1st param(name)        | true         | name of field in view model                |
| 2nd param(using models)| false        | view model using this name of field        |
+------------------------+--------------+--------------------------------------------+
  • Если 2 параметр - null : свойство будет переименовано во всех создаваемых моделях отображения от базовой модели.
@ViewModelName("information")

@ViewModelName("information", "HeroViewModel")
public data: string;

IgnoreViewModel

Декоратор, который используется для удаления свойства из модели отображения.

+--------------------------------------------------------------------------------------------------+
|                              @IgnoreViewModel                                                    |
+--------------------------------------------------------------------------------------------------+
|   Property                   |   Mandatory  |               Definition                           |
+-------------+----------------+--------------+----------------------------------------------------+
| 1st param(name of view model)|     false    |name of view model ,which ignore ths field          |
+------------------------------+--------------+----------------------------------------------------+
  • Если параметр не определен - это свойство игнорируется во всех создаваемых моделях.
  • Если необходимо игнорировать несколько моделей - необходимо написать декоратор для каждой создаваемой модели отбражения.
@IgnoreViewModel()

@IgnoreViewModel("HeroViewModel")

ViewModelType

Декоратор, который используется для смены типа свойства в модели отображения.

+-------------------------------------------------------------------------------------------+
|                        @ViewModelType                                                     |
+-------------------------------------------------------------------------------------------+
|   Property  |  Mandatory   |                      Definition                              | 
+-------------+--------------+--------------------------------------------------------------+
| type        | true         | property type in view model                                  |
| transformer | false        | function used to transform to view model and back im mappers | - complex object
| modelName   | false        | name of view model which will be have property               |
+-------------+--------------+--------------------------------------------------------------+

+-------------------------------------------------------------------------------------------+
|                        transforner Type                                                   |
+-------------------------------------------------------------------------------------------+
|   Property  |  Mandatory   |                      Definition                              | 
+-------------+--------------+--------------------------------------------------------------+
| toView      | true         | transform object which used to transform base model to view  | - complex object
| fromView    | true         | transform object which used to transform view model to base  | - complex object
+-------------+--------------+--------------------------------------------------------------+


+-------------------------------------------------------------------------------------------+
|                        toView/fromView objects                                            |
+-------------------------------------------------------------------------------------------+
|   Property  |  Mandatory   |                      Definition                              | 
+-------------+--------------+--------------------------------------------------------------+

+-------------+--------------+--------------------------------------------------------------+
  • Если свойство "transformer" отсутствует:
    • Если тип свойства - составной, но не сгенерирован или сгенерирован без маппера - глубокое копирование.
    • Если тип скодогенерирован с маппером - используется маппер.
  • Если свойство "modelName" отсутствует, тип используется для всех моделей отображения для данной базовой модели.
    @ViewModelType({
    "modelName": "HeroViewModel",
    "transformer": { "toView" : { "function": toViewModelFunction , "isAsync": true},
                    "fromView": { "function": FromViewModelFunction }},
    "type": HeroDetail})
