Javascript D3带角度cli

我尝试在D3中使用angular cli。 之后

我在node_模块中

在

打字

文件夹中

angular cli build.js

module.exports = function(defaults) {
  var app = new Angular2App(defaults, {
    vendorNpmFiles: ['d3/d3.js']
  });
  return app.toTree();
};

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      ...,
      'd3/build/*.js'
    ]
  });
};

map['d3'] = 'vendor/d3/build';

packages['d3'] = {
  main: 'd3',
  format: 'global' 
};

import * as d3 from 'd3';

index.html

System.config({
  packages: {
    app: {
      format: 'register',
      defaultExtension: 'js'
    }
  },
  d3: {
    'd3': 'vendor/d3/d3.js'
  }      
});

在

条形图

指令中，我尝试导入d3

import {Directive} from 'angular2/core';
import d3 from 'd3';


@Directive({
  selector: 'bar-graph',
  providers: [],
  host: {},

})
export class BarGraph {

  constructor() {
    console.log(d3);
  }

}

但该应用程序从未加载，而且

console.log

表示它试图获取localhost:4200/d3

我也有同样的问题，我在Angular（2.0.0-alpha.27）的旧版本中找到了这个示例，但可能会有所帮助

我认为您需要在

映射

块中添加d3条目：

System.config({
  packages: {
    app: {
      format: 'register',
      defaultExtension: 'js'
    }
  },
  map: { // <-----
    'd3': 'vendor/d3/d3.js'
  }      
});

System.config({
套餐：{
应用程序：{
格式：'寄存器'，
defaultExtension:'js'
}
},
map:{/我开始按照下面的步骤工作

首次安装：

npm install d3 --save

然后将d3添加到
angular cli build.js
，如下所示：

// Angular-CLI build configuration
// This file lists all the node_modules files that will be used in a build
// Also see https://github.com/angular/angular-cli/wiki/3rd-party-libs

/* global require, module */

var Angular2App = require('angular-cli/lib/broccoli/angular2-app');

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      'systemjs/dist/system-polyfills.js',
      'systemjs/dist/system.src.js',
      'zone.js/dist/**/*.+(js|js.map)',
      'es6-shim/es6-shim.js',
      'reflect-metadata/**/*.+(ts|js|js.map)',
      'rxjs/**/*.+(js|js.map)',
      '@angular/**/*.+(js|js.map)',
      'd3/build/d3.js'
    ]
  });
};

并修改您的
系统配置.ts
：

/***********************************************************************************************
 * User Configuration.
 **********************************************************************************************/
/** Map relative paths to URLs. */
const map: any = {
  'moment': 'vendor/moment/moment.js',
  "d3" : "vendor/d3/build/d3.js",
  'jquery': 'vendor/jquery/dist/jquery.js'
};

/** User packages configuration. */
const packages: any = {
  'moment': { format: 'cjs'},
  'jquery': { format: 'global'},
  "d3": { format: 'global'},
};

要确保systemJS加载模块，请向
index.ts
添加导入，并删除
d3
变量，该变量用于避免编译问题：

import 'd3'
declare var d3;

这里有一个有效的答案

npm install d3 --save

angular cli build.js

module.exports = function(defaults) {
  var app = new Angular2App(defaults, {
    vendorNpmFiles: ['d3/d3.js']
  });
  return app.toTree();
};

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      ...,
      'd3/build/*.js'
    ]
  });
};

map['d3'] = 'vendor/d3/build';

packages['d3'] = {
  main: 'd3',
  format: 'global' 
};

import * as d3 from 'd3';

系统配置.js

module.exports = function(defaults) {
  var app = new Angular2App(defaults, {
    vendorNpmFiles: ['d3/d3.js']
  });
  return app.toTree();
};

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      ...,
      'd3/build/*.js'
    ]
  });
};

map['d3'] = 'vendor/d3/build';

packages['d3'] = {
  main: 'd3',
  format: 'global' 
};

import * as d3 from 'd3';

应用程序组件.ts

module.exports = function(defaults) {
  var app = new Angular2App(defaults, {
    vendorNpmFiles: ['d3/d3.js']
  });
  return app.toTree();
};

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      ...,
      'd3/build/*.js'
    ]
  });
};

map['d3'] = 'vendor/d3/build';

packages['d3'] = {
  main: 'd3',
  format: 'global' 
};

import * as d3 from 'd3';
