关于angular.json（关于angularjs1说法,错误的是）

当您将样式添加到angular-cli json时，angular会将所有样式编译为javascript文件，所有这些样式都将添加到head标签。当组件被加载到DOM中时，遵循Angular的组件样式化机制时，行为是相同的。因此，我不建议您添加angular json，而是可以添加index.html

我会向您推荐这篇文章

https://stackoverflow.com/questions/37484937/angular-cli-how-to-add-global-styles/42840828#:~:text=In%20an%20Angular%20project%2C%20when,This%20angular

,

好吧，在尝试了一堆之后，我发现必须在“ angular.json”文件中引用脚本。否则，这有点奇怪。 因此，以下步骤将解决大多数与脚本有关的错误，

  1. 将它们添加到 index.html

    中的脚本标签中

  2. 将它们导入到 angular.json

    的 scripts 字段中

谢谢！

angular default project (angular.json的解读)

angular default project (angular.json的解读)

Change the default Angular project

Understanding it''s purpose and limits

Angular''s default project is nothing more than a string, set in angular.json, to say which project should run with ng commands without a defined project.

Note: The defaultProject key was set to be deprecated in 7.0.0 , but it was blocked because there should be a large discussion about project layout for 8.x.x.

Let''s create a new project called my-app:

$ ng new my-app

It will create an angular.json with the following structure:

{
  ...,
  "projects": {
    "my-app": { ... },
    "my-app-e2e": { ... },
  },
  "defaultProject": "my-app",
}

So, when you run ng serve , it would serve my-app. It would be the same as running ng serve my-app.

Setting a new default project

To understand what values are valid, let''s create a library and an application.

$ ng create application my-application
$ ng create library my-library

Now, we have the following structure:

{
  ...,
  "projects": {
    "my-app": { ... },
    "my-app-e2e": { ... },
    "my-application": { ... },
    "my-application-e2e": { ... },
    "my-library": { ... }
  },
  "defaultProject": "my-app",
}

The highlighted values ( my-app, my-application and my-library) are the valid ones to use as the defaultProject. E2E projects are not valid ones, even if they are listed as projects, because they are used on ng e2e.

If you  created a blank workspace or just deleted the default project string, the first project you create (in this case  my-application) will automatically be set as the default project.

Commands

Each project type has their own commands to use, for example:
Applications: serve, build, test, e2e and xi18n.
Libraries: build and test.

Angular 学习系列 - - angular.uppercase、angular.lowercase、angular.fromJson、angular.toJson

Angular 学习系列 - - angular.uppercase、angular.lowercase、angular.fromJson、angular.toJson

高春辉、王春生、朱峰：关于开源创业的 15 件小事

angular.uppercase

将指定的字符串转换成大写

格式：angular.uppercase(string);

string: 被转换成大写的字符串。

使用代码：

var str = "ABCabc";  var upperCase = angular.uppercase(str);//ABCABC

angular.lowercase

将指定的字符串转换成小写

格式：angular.lowercase(string);

string: 被转换成小写的字符串。

使用代码：

　var str = "ABCabc";  var lowerCase = angular.lowercase(str);//abcabc

这两个方法的翻译也不是很难，也很容易理解。我们在做比较或者做一些字符串处理的时候，需要把大小写都存在的字符串转换为全部大写或者全部小写，这两个方法就是在这时候使用的...

angular. fromJson

反序列化 JSON 字符串

格式：angular.fromJson(str)

str: json 格式的字符串

使用代码：

var str = ''[{ "name": "A", "age": "1" }, { "name": "B", "age": "2" }, { "name": "C", "age": "3" }]'';var con = angular.fromJson(str);//con=[{ "name": "A", "age": "1" }, { "name": "B", "age": "2" }, { "name": "C", "age": "3" }]

angular. toJson

序列化 JSON 字符串

格式：angular.toJson(str)

str: 要转 string（json 格式的字符串）的 json 数据。

使用代码：

var str = [{ "name": "A", "age": "1" }, { "name": "B", "age": "2" }, { "name": "C", "age": "3" }];var con = angular.toJson(str);  //con = "[{ \"name\": \"A\", \"age\": \"1\" }, { \"name\": \"B\", \"age\": \"2\" }, { \"name\": \"C\", \"age\": \"3\" }]"

以上是这两个方法的使用，angular.fromJson 是将 json 格式的字符串转换为 json 格式数据，江湖人称 “反序列化 JSON 字符串”；angular.toJson 是将 json 格式的数据转换 “json 格式的字符串”（虽然有点绕口，但其本质是字符串），江湖人称 “序列化 JSON 字符串”。

Angular 项目里 angular.json 文件内容的学习笔记

Angular 项目里 angular.json 文件内容的学习笔记

看一个基于 Angular 的 SAP Spartacus 项目里 angular.json 的例子：

  • version: The configuration-file version.

  • newProjectRoot: Path where new projects are created. Absolute or relative to the workspace folder.

  • defaultProject: Default project name to use in commands, where not provided as an argument. When you use ng new to create a new app in a new workspace, that app is the default project for the workspace until you change it here.

  • schematics : A set of schematics that customize the ng generate sub-command option defaults for this workspace. See Generation schematics below.

  • projects : Contains a subsection for each project (library or application) in the workspace, with the per-project configuration options.

Angular generation schematics are instructions for modifying a project by adding files or modifying existing files.

Angular 生成原理图是一系列指令，用于通过添加新文件或者修改已有文件的方式来修改一个项目。

Individual schematics for the default Angular CLI ng generate sub-commands are collected in the package @schematics/angular.

ng generate 子命令各自的原理图，在 @schematics/angular 包里维护。

Specify the schematic name for a subcommand in the format schematic-package:schematic-name; for example, the schematic for generating a component is @schematics/angular:component.

给子命令指定原理图的语法：schematic-package + 冒号 + schematic-name，例如 @schematics/angular:component，用于生成一个 Component.

什么是 architect

Architect is the tool that the CLI uses to perform complex tasks, such as compilation and test running.

Architect 是 CLI 使用的工具，用来执行复杂任务，比如编译代码和运行测试。

Architect is a shell that runs a specified builder to perform a given task, according to a target configuration.

Architect 是一个 shell，运行一个特定的 builder，根据一个 target 配置来执行某种任务。

Default Architect builders and targets

Angular defines default builders for use with specific CLI commands, or with the general ng run command.

Angular 为特定的 CLI 命令定义默认 builder.

The JSON schemas that define the options and defaults for each of these default builders are collected in the
@angular-devkit/build-angular
package.

每个默认 builder 的 options 定义的 JSON schemas，定义在 @angular-devkit/build-angular 开发包里:

比如 ng serve, 执行的 builder 是 @angular-devkit/build-angular:dev-server：A development server that provides live reloading.

什么是 builder

A function that uses the Architect API to perform a complex process such as "build" or "test". The builder code is defined in an npm package.

Builder 是一种 function，使用 Architect API 来执行复杂的流程，比如 build 或者 test. Builder 代码定义在 npm 包里。

For example, browserBuilder runs a webpack build for a browser target and KarmaBuilder starts the Karma server and runs a webpack build for unit tests.

例如，browserBuilder 为一个 browser target 运行一个 webpack build.

The schemas configure options for the following builders.

  • app-shell
  • browser
  • dev-server
  • extract-i18n
  • karma
  • protractor
  • server
  • tslint

The architect section of angular.json contains a set of Architect targets.

angular.json 的 architect 区域包含了一系列 Architect targets.

Each target object specifies the builder for that target, which is the npm package for the tool that Architect runs.

每个 target 都指定一个 builder，该 builder 为该 target 服务。builder 的实现位于一个 npm package 里。

The npm package for the build tool used to create this target. The default builder for an application (ng build myApp) is @angular-devkit/build-angular:browser, which uses the webpack package bundler.

默认使用 webpack 的 package bundler 来完成 ng build.

Note that a different builder is used for building a library (ng build myLib).

The architect/extract-i18n section configures defaults for options of the ng extract-i18n command, which extracts marked message strings from source code and outputs translation files.

生成可供翻译的 translation files.

The architect/server section configures defaults for creating a Universal app with server-side rendering, using the ng run :server command.

生成支持服务器端渲染的 SSR 应用。

The architect/app-shell section configures defaults for creating an app shell for a progressive web app (PWA), using the ng run :app-shell command.

创建一个用于 PWA 应用的 app shell.

assets 配置

Each build target configuration can include an assets array that lists files or folders you want to copy as-is when building your project. By default, the src/assets/ folder and src/favicon.ico are copied over.

静态资源文件。

assets 里的通配符

  • glob: A node-glob using input as base directory.
  • input: A path relative to the workspace root.
  • output: A path relative to outDir (default is dist/project-name). Because of the security implications, the CLI never writes files outside of the project output path.

由于安全考虑，CLI 绝对不会在项目 output path 之外写入文件。

  • ignore: A list of globs to exclude.
  • followSymlinks: Allow glob patterns to follow symlink directories. This allows subdirectories of the symlink to be searched. Defaults to false.

可以用 glob 的这个功能，从项目文件夹之外的位置拷贝文件到 outdir 去。

例如：

"assets": [
 {
   "glob": "**/*",
   "input": "./node_modules/some-package/images",
   "output": "/some-package/"
 }
]

效果：

The contents of node_modules/some-package/images/ will be available in dist/some-package/.

budgets

Default size-budget type and threshholds for all or parts of your app. You can configure the builder to report a warning or an error when the output reaches or exceeds a threshold size.

Angular-chart.js 使用说明（基于angular.js工程）

Angular-chart.js 使用说明（基于angular.js工程）

Angular-chart.js是基于Chart.js的angular组件，引入项目后直接操作数据即可。

  引用方法：

   分别将Chart.js、angular-chart.js、angular-chart.css等文件引入工程（angular工程）中（注意引入顺序）。

   在app.js中module中引入‘chart.js’。

   创建你的项目的controller和html并用路由绑定。

  代码：

   在controller中写入以下代码：

复制代码 
//Line Chart
    $scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
    $scope.series = [''Series A'', ''Series B''];

    var dataA = [
      [65, 59, 80, 81, 56, 55, 40],
      [28, 48, 40, 19, 86, 27, 90]
    ];
    var dataB = [
      [11, 33, 54, 86, 51, 97, 33],
      [64, 53, 24, 21, 56, 12, 90]
    ];
    $scope.data =dataA;
    $scope.onClick = function (points, evt) {
      $log.debug(points, evt);
    };

    //change data
    $scope.changeData= function () {
      if($scope.data==dataA){
        $scope.data=dataB;
      }else{
        $scope.data=dataA;
      }
      $log.debug(''当前的数据更改为：'',$scope.data);
    };


    //Bar Chart
    $scope.labelsBar = [''2006'', ''2007'', ''2008'', ''2009'', ''2010'', ''2011'', ''2012''];
    $scope.seriesBar = [''Series A'', ''Series B''];

    $scope.dataBar = [
      [65, 59, 80, 81, 56, 55, 40],
      [28, 48, 40, 19, 86, 27, 90]
    ];


    //Doughnut Chart
    $scope.labelsDoughnut = ["Download Sales", "In-Store Sales", "Mail-Order Sales"];
    $scope.dataDoughnut = [300, 500, 100];


    //Radar Chart
    $scope.labelsRadar =["Eating", "Drinking", "Sleeping", "Designing", "Coding", "Cycling", "Running"];

    $scope.dataRadar = [
      [65, 59, 90, 81, 56, 55, 40],
      [28, 48, 40, 19, 96, 27, 100]
    ];

    //Pie Chart
    $scope.labelsPie = ["Download Sales", "In-Store Sales", "Mail-Order Sales", "Tele Sales", "Corporate Sales"];
    $scope.dataPie = [300, 500, 100, 40, 120];

    //Dynamic Chart
    $scope.labelsDynamic = ["Download Sales", "In-Store Sales", "Mail-Order Sales", "Tele Sales", "Corporate Sales"];
    $scope.dataDynamic = [300, 500, 100, 40, 120];
    $scope.typeDynamic = ''PolarArea'';

    $scope.toggle = function () {
      $scope.typeDynamic = $scope.typeDynamic === ''PolarArea'' ?
        ''Pie'' : ''PolarArea'';
    };
复制代码

   在相应的html中写入以下代码：

复制代码 
<div>
      <buttonng-click="changeData()">更改数据</button>
      <canvas id="line"chart-data="data"
              chart-labels="labels" chart-legend="true" chart-series="series"
              chart-click="onClick">
      </canvas>
    </div>


    <div>
      <canvas id="bar"chart-data="dataBar" chart-labels="labelsBar" chart-series="seriesBar">
      </canvas>
    </div>

    <div>
      <canvas id="doughnut"chart-data="dataDoughnut" chart-labels="labelsDoughnut">
      </canvas>
    </div>

    <div>
      <canvas id="radar"chart-data="dataRadar" chart-labels="labelsRadar">
      </canvas>
    </div>

    <div>
      <canvas id="polar-area"chart-data="dataPie" chart-labels="labelsPie">
      </canvas>
    </div>

    <div>
      <buttonng-click="toggle()">toggle</button>
      <canvas id="base"chart-type="typeDynamic"
              chart-data="dataDynamic" chart-labels="labelsDynamic" chart-legend="true">
      </canvas>
    </div>
